@@MrXispas Neither was Carl Sagan. He believed in evolution, for which there is absolutely no scientific evidence. "In the beginning God created the heaven and the earth" (Genesis 1:1, KJV). If he couldn't get history right, he couldn't get science right.
I just realized I had totally forgotten what it was like when everyone in congress could manage to shut the hell up for a quarter of an hour until someone was done talking. Listening to Carl while they were doing that was icing on the cake. Miss this guy a lot.
I also miss him and we need more rational minds like his, but I think this was just his opening statement. His chance to have his say before questions and bickering.
I can even hear the squeaky voice of ted Cruz asking something genius like "But may I ask, if you say we can;t see the gasses, how can we be sure they are here?"
Yes they were listening to a nice 7th grade science lesson and little more. The predictions have been wrong and will continue to be wrong. Yes the Earth's climate is changing and we can do nothing to stop it. Nothing wrong with looking to new renewable energy source, (those that actually work and are actually renewable). Unfortunately nefarious new world order Marxists have hi-jacked the issue. What the climate accords and green new deals attempt to accomplish have no relationship with naturally accruing climate change. Do not conflate truth with lies.
@@SPBurt1 Yeah the earth is flat. Feminists are stealing our jobs. White racism exist. Trump won the elections. Keep it up wokeman. Save us from the reptilians.
@@raynaylor8602 Quantitative data bears out the facts of climate change. More frequent and more intense weather events: floods, droughts, fires, destructive storms, melting of glaciers, decrease in populations of animals in polar regions, ocean acidification, reduction in crop yields, sea level rise - all are observable and the data is available to the public.
No too much CO2, the amount of which cannot be ascertained. For example CO2 has been as high as 2,000 PPM in the atmosphere when dinosaurs roamed the Earth. It is currently 400 PPM. We are certaintly not turning into Venus.
Viewing this video from 40 years ago, I am struck by how the senators are actually listening, quietly, respectfully, paying attention without interrupting Dr. Sagan during this cogent, intelligent remarks. A far cry from the performative nature of government hearings today.
Yet the World is still spinning plants are still growing and no eco apocalypse has happened. Fear mongering then is still the same now just more dramatic
@@EdBate after 5 decades of getting it wrong. Yes it's time to admit that climate alarmists are frauds. It's simple to assume that this cult is right despite the fact they are overwhelmingly wrong. What's simple is listening to others not follow the rules that they are setting for you. Aka private jets, large envoys, energy consumption and production in relation to carbon footprints. Co2 is not the enemy. Europe is full of climate droughts and heat waves long before the industrial revolution and multi billion population. Blaming the low water supply on man made climate change is just absurd. 1935 was the hottest year on record. Again long before mass industrialization and energy production. Climate activists simply want to pass new taxes to attempt to control the economy and further damage the dollar. Climate taxes is something I'll pass on. You should too
It's a terrible thing we're doing to our children and grandchildren both then and today we're still not taking enough action to stop human caused greenhouse effect.
@@EdBate welllll I think most of the countries have done a lot. It’s the other countries that haven’t done much at all that would at least have us way better off. I’m in Canada and we contribute a very low percentage to climate change and we have carbon tax and blah blah blah on and on. No matter what we do it gets worse. China and Middle East must help out
Buzz word, butzz word, my political enemy **smear***, buzzword, triggerword, vote, change, uplift word, fearmonger, uplift, buzzword. Yeah, that gets old ^^^^
Carl Sagan was as an inspiration, R.I.P. he could explain the most complex subjects in the simplest terms that even a child could understand. An extraordinary teacher.
We’re not questioning his message, especially considering how we’re not even remotely close to the dirtiest country on the planet (to be fair, Florida isn’t helping our case). We’re questioning why the hell the rest of the world is ignoring this man’s message.
People dont understand that message :) ecology should be obvious for all but must be explained slowly. Its not a "rocket science", dont produce so much trash and control factories is a start. It's clear this famous scientist is not panicking like people today. You claim "noone" touched this subject and it's just childish. People work to minimize bad influence and another group is making money on panicked people - "nobody saves the planet, we will all die!" :) some day we will but people wiil kill people much faster than greenhouse effect. There is something to focus on.
Nobody's saying the climate doesn't change. We're saying the world isn't ending in 12 years or whatever insane bullshit people are pushing politically. If you read the IPCC report it actually says if we go to zero emissions tomorrow, which is impossible, that sea level rise and atmospheric warming will continue unabated for CENTURIES. So literally anything that we experience in our lifetimes is UNAVOIDABLE.
@@anusmcgee4150 Well the US is. You can't blame China for the pollution they're making for the products the US is buying cheaply. Their pollution is for the benefit of the western world.
Within 10 seconds of the video starting you can see how much people's respect, intelligence, and general demeanor have changed. It's _scary_ I had no idea it was this bad.
Carl Sagan was demonized by the majority of Americans (as the majority, not just plurality was Christian) during his time. The deep influence of the church reverberated across schools and homes alike because Sagan challenged creationism. Let's not pretend that he got respected by a majority of Americans when he was alive.
Everyone’s talking about how respectful and calm everyone is but no one is talking about how young they are. Far from the deranged nursing home battle royal we have today.
Yeah, you're right, young guns like Matt Gaetz and Marjorie Taylor Greene and Lauren Boebert and J.D. Vance and Josh Hawley, they're really respectful and calm and completely not deranged in any way. What alternative reality are you living in, Nicole?
@H Boogie Michio Kaku merely emulates someone like Carl Sagan who focuses on present matters. Michio Kaku is someone who says we're at level "zero" as a civilization cause we don't have a "dison sphere" around the sun, and because of that we're primitive and dumb!
Where is that? *With Glacier National Park having to take down the signs that predicted they would be GONE by* *2020??* *SURELY the SNOWS of Kilimanjaro are NO LONGER there RIGHT??* *AL GORE PREDICTED THEY would be gone in 2015 or something...WRONG, again*
His closing message was succent and spot on: "I think that what is essential for this problem is a global consciousness. A view that transcends our exclusive identifications with the generational and political groupings into which, by accident, we have been born. The solution to these problems requires a perspective that embraces the planet and the future, because we are all in this greenhouse together."
unfortunately this change in perspective would be more like a religious awakening. I think mankind literally values money more than its own existence. Pessimistic I know.
How realistic is it to call for the birth of a global consciousness? I'm pretty disappointed that he wasn't able to come up with anything better than that. Like... Investing the price of 2 aircraft carriers a year for 30 years will invent the technology to solve CO2 emissions. Dr. Sagan was a great scientist but maybe not a great judge of our potential as a species. One gallon of gasoline contains the equivalent of 400 person hours of labor. Now, go take that gallon a day away from 8 billion people and tell them they have to work 50 times longer for the same economic output. Not going to happen.
Highly likely he's in hell, far from resting in peace, because he rejected the one and only atonement for sin which every human is offered but sadly, many reject.
I was raised with hardcore creationist parents and they completely demonized Carl Sagan. As an adult I have learned more about him and have listened to him speak and educate and I am always blown away by not only his passion for science but his compassion for the life around him. He is a national treasure.
Carbon dioxide at 0.04% is a 2,500th part of the atmosphere. that means to warm the climate by just 1"c carbon dioxide molecules must capture 2,500"c of heat energy. That is impossible. It also breaks the fundamental laws of thermodynamics. Methane at 0.00017% is a 600,000th of the atmosphere so it's even more impossible. To cause 1°c of heating methane would have to capture 600,000°c of heat energy. Problematic as this is over a hundred times hotter than the surface of the sun. (Methane rapidly breaks down in sunlight). However, the climate is changing. This is because of deliberate geoengineering programmes, inparticular ozone thinning away from the poles. Though largely unreported ozone thinning effect is directly observable producing an unnaturally bright sun and even s bright moon. Under these conditions the pain felt when looking at the sun is not only from the increase in visible light but the much larger increase in infrared. (Look up at the sky and you will see a range of geoengineering operations in progress, these include chemtrail induced cloud or hazing, ripple patterns caused by HAARP installations, bizarre and unnatural cloud formations). Climate change is a programme to force change in accordance with the implementation of agenda 21/2030. Current events demonstrate this transition is well underway and will involve massive population cull through injected nanotech (re transhumanist programme). Agenda 21 also sees the permanent loss of all property rights with the introduction of universal basic income (ref nesara/gesara) and has/is being promoted by the World Economic Forum. 'You will own nothing and you will be happy' WEF In a depopulated world the surviving brainwashed and controlled population will be confined to mega cities. Carbon limits will be used to restrict consumption and liberty. Meanwhile the re-greened wilderness will be the exclusive playground of the ultra rich elite posing as conservationists. The co2 hoax amounts to the theft of the world and the enslavement of humanity by a parasitic few. Welcome to the future! _________ I have included a debunking of 'accumulated heat' as it is so often used to explain how trace elements, so called 'greenhouse gasses', can warm the planet. Accumulated heat whilst sounding a reasonable explanation of how heat can build up is rather nothing more than gobbledygook. In fact it shows those using such arguments do not even understand what heat is. When we measure temperature we are measuring the heat energy a thing is losing. In short heat is a measurement of flow, the transfer of heat energy and this will always be in the direction towards the colder. For this reason a thing can never 'accumulate heat' in the way those advocating co2 climate change describe. The temperature of a body is the measure of heat output, it can never be greater than the measure of heat input. Output = input. When a thing is warmed it is heated to an equivalent of the heat input. If this input is not maintained it will cool. Those that propose that heat can build up to be hotter than the total measure of heat input at a given time either do not understand what heat is or are being deliberately misleading. To illustrate, an object being heated by a flame can never become hotter than that flame, it's temperature cannot rise inexorably to the temperature of the sun for instance. heat cannot be accumulated. When we think about it common sense tells us this must be the case. Nasa and even nobel prize winning physicists have expounded 'accumulated heat' as the explanation how co2 is able to warm the atmosphere. They claim that over hundreds of years co2 has captured heat energy and this heat has 'accumulated' to produce a serious warming effect. As I have just explained, this is totally impossible and fundamentally violates all the laws of thermodynamics. That respected scientists should support such uneducated, unthinking nonsense is disturbing and only reflects that in terms of being able to think clearly about a subject they have no facility or inclination. These are the dark ages of science. Belief has outweighed logic or any critical thought. It tells us that we should not unquestioningly accept anything we are told, that experts can be fools. (nb: Be aware of attempts to discard thermodynamics by talking about biology. eg. 'it only takes a drop of arsenic to kill a person.' This would be somewhat desperate, muddled thinking. clearly biological processes based on the reaction of a cell are not the same as the laws of physics/thermodynamics).
Continued... It is impossible to trap more energy than the energy available. This is the first law of thermodynamics. Furthermore, climate change models require that this heat must be from radiant heat from the Earth's surface. The reason this must be so is explained by the thought experiment as follows: 'Five photons of energy from the sun, one photon is absorbed by CO2. Does the planet warm more than if all five photons had hit the surface? ' Anything that captures radiant energy will in turn radiate 50% of its energy back to space. This is as much a point of logic. It is also easily proved by everyday experience. When a cloud passes overhead it immediately becomes colder, this is because radiant energy is absorbed by the water molecules and the same will be true of CO2. Carbon dioxide can only reduce surface temps though as I explained the proportion of CO2 is so fractional as to have any measurable effect. Clouds, and the fact that nights are colder than days, also demonstrates that Earth loses heat extremely quickly and shows the importance of surface heating from direct sunlight. It also explains why all those peddling the CO2 climate hoax have to ignore infrared in direct sunlight. Were they not to do so the whole charade falls apart as it means half of all infrared energy from the Sun will be radiated back out to space. This is problematic as almost half of the Sun's radiant energy IS INFRARED!!! ... OUCH! Fractional elements have fractional effects. We understand this in everyday common sense as proportion. To imagine carbon dioxide can capture this magnitude of energy is absurd and breaks the basic law of thermodynamics. Were it so all energy needs could be solved through the magical energy capturing power of CO2. There are many other fundamental problems with the CO2 climate change model. Eg that CO2 is highly soluble and is washed out extremely quickly in rainfall; that CO2 levels fluctuate drastically seasonally showing on earth with its high rainfall CO2 is not a gas that accumulates; that heat cannot be trapped in oceans as described in climate models as they are more 'energy dense' than the adjacent air, rather if oceans are becoming warmer it can only be from direct sunlight; that increasing biomass increases CO2 because it increases the carbon in cycle; that correlation is not causation otherwise it could be said daisies cause hot temperatures because there are more daisies when it is warm; that there is extremely dodgy Victorian science/politics behind Ice Ages which is never questioned or examined - eg mammoths despite claims otherwise are not adapted to cold but rather appear to be cold temperate animals similar to highland cattle, their blood is not antifreeze as claimed, they have no sebaceous glands, hair is long but sparse - even yaks being hairier, mammoth remains as far south as Mexico; that how can ice cores be an accurate record of the past if miles of ice have supposedly melted?; that Milankovitch Cycles mean that the Southern Hemisphere is currently in the middle of it's Great Ice Age; that the hypothesis that burning of forest subsequent to Ice Ages resulted in warming is logically inconsistent as 'no new carbon' has been introduced into cycle this all being carbon already in cycle and in any case would be washed out almost immediately; that CO2 levels are at a geological low; that the oxygen cycle is intertwined with the carbon cycle and dependent on it; that life is carbon based and CO2 is essential; that a halving of CO2 levels would result in the extinction of nearly all plant species - problematic as it in turn means theorised measures of atmospheric CO2 during Ice Ages cannot be correct - contrary there was a proliferation of megafauna; that alarmingly, plants already struggle to get enough CO2 for growth which is why farmers will often increase CO2 in greenhouses to promote yields; that the so called 'proofs' showing CO2 is able to capture radiant heat energy only prove the opposite and how very minor this is - that atmospheric concentrations of 0.04% CO2 thermal effect would be far too fractional to even be measured; that comparisons to other planets eg Venus/Mars prove CO2 does not capture the proportion of energy claimed and maybe this is why these comparisons are done less and less; that in order to explain vastly higher concentrations of CO2 in the geological past the sun is deemed to have increased its output this despite losing solar mass (gravitational mass) as fuel, this in turn meaning that the orbits of all the planets are all moving away from the sun - such hypothesis where solar activity is used to exactly compensate for holes in the CO2 climate theory is to ignore other evidential explanations of stars such as the 'electric universe theory'; that the geological archive shows periods of millions of years when CO2 and temperature were heading in opposite directions... etc).

It's sad that we are not intelligent enough and ethical enough to elect people with ethics that understand these issues and do something about them. Thing is, doing something would directly cost the taxpayer money and affect the 1st world lives they lead. Until it's too late, and then it's too late.
@@RocketdogandSeptembr the world is not fine, bigger moron.

It's going straight to proverbial hell, because of morons like you.

Couldn't agree with you more! No one has ever explained climate change better than Carl Sagan! In fact many of his key point's he makes are repeated word for word by others but either come off too boring or biased. Carl Sagan explains in better in 15 minutes than Al Gore in a hour. Also he was respected by people on both sides of the isle.
Totally agree. Since the ice caps melted we have seen the sea rise dramatically and as soon as the water reaches the shore we are going to see some horrible flooding.
@@johnpollard744 If the increased temperature just affected homo sapiens, I would be okay with that. However, with the fact that literally thousands to millions of species will be negatively affected is what deeply disturbs me.

We've emitted far more carbon since 1985 than we did before, so the solutions are more urgent as well as better developed. We can't turn fossil fuels off immediately, Sagan says. No, but the IEA now says we don't need any new wells or fossil infrastructure.
@@robertmarmaduke186You’re seriously illiterate. He is exactly right about all of this. It’s verifiable. It’s proven facts. These things are not up for debate.

Your vocabulary can’t handle this presentation and you don’t know the first thing about planetary sciences which is that all systems are connected.
Politicians are generally not intelligent enough to grasp the concepts he'd talk about. They would pretend to understand and do nothing, as they do with everything else.
I'm so glad that this whole problem was acknowledged and addressed back in the days and is of no concern for current and future generations. Everrising sea levels, everrising temperatures and extreme heat, wildfires, migration movements, intensifying of extreme wheater, droughts and floodings sure don't sound so good, but I'm relieved everyone was aware of the incredible inertia of the global climate system and humanity together solved that problem.
@@frogwood1713Yeah it's a joke. The politicians back then were at least trained enough to not interrupt the experts that don't impact policy decisions. Today politicians overtly make it clear they don't care what any expert says unless it is service to our corporate masters.
His ability to talk to them in a way that they would understand as non-scientists is incredible. He speaks so clearly and conveys his points so well. We'd have been better off with him in congress!
If more master degree scientist types went into politics we would have the right laws passed and corporations ravaging earth would stop in a few decades.
All representatives should have a science degree of some sort, this country is run by lawyers, that's why we're doing so great. Carl was where he belonged, acurately predicting the future in 50 years. F'in amazing, both that he was so dead on and that these slack jawed yokels didn't remember any of it after lunch
A scientist is also a human being. That is to say that, in order to understand stuff, one needs to be able to dumb it down for oneself as well. We have this saying: "if you can't explain it to your grandma, then you don't know what you're talking about."
@@thewhosjoeEspecially US and Europe. Don't blame China as Carl said for using that energy to develop as much as we did for more than a century now. In Pekin they suffocate each summer so i think China is cleary awared of the situation. As Carl said, we need a worldwide cooperation to take these decisions not as nations, but as a specy.
Carl Sagan certainly was a great man and a great scientist. But it needs to be noted that he was a physicist, not a geologist or planetologist and certainly not a climatologist. We also got decades more of data and thought about this. He failed to take into account the gas pressure on Venus and how the composition of gases would be unimportant due to adiabatic pressure and temperature. Else Mars, with an almost entirely CO2-atmosphere would have a similar greenhouse effect and temperatures. Secondly he failed to take into account saturation. He correctly states that, if we saw the world in the absorption spectra, it would be black. Adding further absorbers is irrelevant when everything at 50microns already is absorbed, cause nothing more can be absorbed at these wavelengths. So, this endorsement of a globalist fight against climate change should be discarded for the fundamental scientific failures Carl Sagan made in this speech, I am very sorry to say.
@@donaldduck830 Not sure which yahoo you got this information from but you've been duped. Compression of gasses (what you're calling adiabetic pressure) does indeed cause a temperature rise, but only when going from lower pressure to higher pressure. In contrast a lowering of pressure causes a sudden drop in temperature. However the atmosphere of venus is not changing pressure. It's high pressure, but it's stable and unchanging. Thus there is no warming as a result of that pressure. The high pressure of venus is relevant here because it means that the amount of total CO2 in the atmosphere is MUCH higher than just reading the composition would expect. As Carl Sagan correctly states, this is an extreme example and not the expectation for earth. Mars is barely worth mentioning. While it is 95% carbon dioxide, the atmosphere is so thin that this is almost irrelevant to anything.
40 years later and there are still many humans who don’t believe climate change is real. His words fell on deaf ears and nothing has been done to address this issue. I am so glad he didn’t live to see the shocking weather events happening worldwide now. Still miss this incredible man, who tried desperately hard to warn us 😢
How do you, or how can you prove humans have been the major driver of climate change when the latest 10,000 years have been the most stable in earths beginning. And in the last 10,000 years have been a steady and very very slow change in temperature.
I never knew Mr Sagan or met him. But I did watch his documentary Cosmos, all of it as an adult in the early 2000s. The cosmos was broadcast in Malaysia in early 80s. But some very "smart" tv program executive in Radio Television Malaysia scheduled it after my 8 year old bedtime at 10pm. So I did not see it in the 1980s. I got my first telescope in 2003 after watching the whole cosmos series and realizing I actually love astronomy. I wished I watched Cosmos in 1980s and made a different career choice but I made the most of the past 20 years. 😊, I am happy. Tq Mr Sagan. RIP
Carl Sagans unparalleled ability to communicate has me lamenting his death. He taught me more about learning and science than any other. We still miss his counsel we still need his clarity and I valued his incorruptibility among many other things. I wonder about what he'd have to say now. The prognosis for us wouldn't be good at all.
@Just think What a lunatic; come off of this crazy narrative. I'm no liberal or screaming "snowflake" but your incendiary and uneducated comment is just plain ignorance. When you take the time to learn the science of atmospheric science (meteorology) and then study basic chemistry and physics you will come to a new realization. Your weather isn't created for "your" or me by "God" or any other divine being; it's the process of the Laws of Thermodynamics when combined with the earths rotational movement, incoming solar radiation, and water. Speak when you can explain the process of a thunderstorm: how it forms, why and how there is lightning, and what makes hail and ultimately rain?! Then you will have a basis of knowledge that is demonstrable; not some trite dribble and passive, baseless insult. If you are so motivated, watch some videos of the brilliant Brian Cox (physicist, not athlete) for quick catch-up courses on science you seemingly missed out on. Good luck.
Guy McPherson, David Suzuki, and Bill Nye are among the climate scientists carrying on what Carl Sagan explained in those days. They are described as "doomists".
This might be the smartest and most effective summary of the climate crisis you can find on the internet. Incredible that the entire diagnosis of the problem, the solutions and the obstacles in the way were evident all the way back in 1985 and yet we have still failed.
I really feel as though Jeff Goldblum based his portrayal of Ian Malcolm in Jurassic Park on this man - and added in some rocket-fuel rockstar charisma for good measure. The voice tone and pitch height, and the use of prosodic stress, are a near-perfect match. Carl Sagan was a very good scientist, but most importantly, he was an extraordinary communicator; he really uses his voice like a Juilliard-trained actor, draws his audience in, and this gives his words a weight and a sincerity that is unmistakable as well as impossible to ignore.
Carl Sagan was also a consultant on the 1984 movie "Threads", about the threat of nuclear arms. It is, by far and bar none, the most frightening movie I have ever seen. He was literally trying to save the world, one measured word at a time.
@@ballparkjebusite After nuclear energy started making headway and actually improving our energy infrastructure, the Left took a stance against it. They purposely conflated two separate issues, nuclear weapons and nuclear reactors, into one umbrella item to be an activist against. The average person likes to feel like a concerned citizen but at the same time has extremely little knowledge of either "nuke". The result was no growth in reactors since the 80s. Of course, our energy demand didn't shrink an iota, so the shortfall of not having nuclear energy meant extra pollution from coal or gas plants. Thanks Carl.
This was the calmest climate change talk I’ve ever heard. I think laying out the facts in a more objective way like this is so important, people can only grab onto the facts
I'm a big fan so scientific objectivity, but thinking facts alone will convince people is sometimes criticised as the 'deficit model'. Unless you are more motivated to learn and understand than you are to protect them perceived interests of your community, you may ignore or reject uncomfortable knowledge however you can. See Sagan in 1990 on Croesus versus Cassandra and how relating to climate change 'denial is not just a river in Egypt'. There's also a famous quotation of his about how painful it's is to admit you've been bamboozled by charlatans. So there need to be honest channels of communicating besides facts. You might be interested in Prof Katherine Hayhoe's book "Saving Us" about the importance of bonding and finding common ground with people and inspiring them with effective climate action. It seems many people whose political tribe or personality compels them to remain silent on global threats still see the local benefits of wind power and EVs. If facts aren't the problem, why am I writing all this :)
@@davedixon2068 And there are still people selling sand to ostriches. Surveys show (Yale Six Americas) most people aren't like that. The majority are concerned, but want to know what to do. Sagan's answers to that are broadly still correct, but other experts (like Mike Berners-Lee and Katharine Hayhoe) are a bit more up-to-date.
@@davedixon2068 That's an optimistic view. For every person doing the 'LALALA', there are 3 people who are so over their heads working 3 jobs to make ends meet they have no time to consider the future, and 1 person screaming 'trans - culture war - witch hunt - woke - great replacement - child abuse - baby killer - fascist' at everyone they meet, whilst engaging in or supporting at least one of the things they are screaming at others about. When those last people manage to elect an immature narcissist to 'the leader of the free world', alongside other countries where they don't even elect their own less immature and more deadly narcissist dictators, there is not a hope for real consensus to deal with the most important problems - they are less important than feeding the endless void of such leaders.
I read his book, Cosmos, as a young teenager and it influenced me to study science at university. While I did not turn out to be a natural scientist, I’ve remained very interested in these issues. It seems now that we tend to hear from politicians or activists but rarely from people so reasonable as Sagan.
Because everything that has to be said has been said. We need action now. Policians do what is popular with the citizens. But citizens are stupid. So a few activists try to press the issue. But most of them are stupid too, so they overshoot, asking for too much, resulting in the general population being less fond of the topic, resulting in politicians doing less. We're doomed. Just enjoy your life, don't get kids and wait for the end.
@@inanitas We are not doomed but we are very late. Mankind will not be extinct because of climate change but possibly from wars it can lead to. Climate change will kill millions and make life very tough to billions, how many of each is up to us. EU is doing something, have you heard of the Carbon Border Adjustment Mechanism? My representative in the EU-Parliament has played a major role in creating some building renovation rules that will reduce energy consumption, this is copied by the Indian government. And Denmark, Germany, the Netherlands and Belgium have decided to build 150 GW wind turbines in the North Sea. So I hope you will support the efforts! The reason why we elect politicians which do too little is because we are too poorly educated to elect adequate ones.
If Mr. Sagan was alive today, I can't imagine how discouraged he would be in seeing how little has been done to fight this global threat, due in no small part to the massive resistance by those who benefit from the continual poisoning of this planet, and those who so readily believe them.
People have generally been pretty good at reacting to an immediate threat like Pearl Harbour or a killer virus. Long term threats though we are not geared up well to deal with, most governments think only in terms of the next 5 years of their term, also the fossil fuel industry obviously out a lot of effort into delaying or denying need for change.
You have no idea what you're talking about. And I feel very sad for you. You falsely believe our planet is dying based off of a faulty understanding of the impacts of global warming. I mean this from my heart because if I believed the incorrect popular narrative, I, too, would be shitting my pants
@@jarren32Oh so understand climate science better than tens of thousand physicists studying and simulating with success the effects of climate change?

Also most predictions done back then when the science itself was fairly new and with far less computing power than today has been spot on. And Sagan's quotes nails it, he foresaw everything that's happening today, including the anti science "don't look up" crowd. Edit: This one: “I have a foreboding of an America in my children's or grandchildren's time -- when the United States is a service and information economy; when nearly all the manufacturing industries have slipped away to other countries; when awesome technological powers are in the hands of a very few, and no one representing the public interest can even grasp the issues; when the people have lost the ability to set their own agendas or knowledgeably question those in authority; when, clutching our crystals and nervously consulting our horoscopes, our critical faculties in decline, unable to distinguish between what feels good and what's true, we slide, almost without noticing, back into superstition and darkness... The dumbing down of American is most evident in the slow decay of substantive content in the enormously influential media, the 30 second sound bites (now down to 10 seconds or less), lowest common denominator programming, credulous presentations on pseudoscience and superstition, but especially a kind of celebration of ignorance”
@@gottagowork He didn't foresee anything, he just presented the pseudoscience, which is being done till today. If a theory is false, that does not depend on computing power.

How the world was hijacked by con artists is a question that induced scientists like Naomi Oreskes and Geoffrey Supran to move into the humanities to answer it. Have you seen 'The Power of Big Oil' (PBS title( or 'Big Oil Vs The World' (BBC title)'?

Carl Sagan was certainly amazing, his thoughts in 1985 spell out the irresponsibility that was put on-ice back then, and is now resurfacing today in 2022 is a testament to the criminality of capitalism. It displays our willingness to destroy this planet many times over then shrug like dumb monkeys about what happened. Perhaps it is a blessing to be an ancient and deceased civilization because our bones and decomposed bodies will not create the lakes of underground oil that the flora and fauna of the dinosaurs did. A future society will have to consider non-fossil fuel sources in order to survive. That is, if they ever get another chance like ours.
@@TheMPBailey "Climate changed" has NEVER been "put on ice". Every few years, our propaganda "news" media predicts eminent collapse of the environment that nearly every single kid between 13 and 23 believes is about to happen, and in about 10 - 15 years. Alexandria Ocasio-Cortez did the latest announcement then Greta Thunberg. Cortez said the world was about to end in 12 years in 2018. Gore predicted the end of all major glaciers in under 10 years in 2006 and the north pole being ice free within the next decade. Neither came to pass. We were supposed to run out of oil by 2005 due to Hubbert's Peak in 2005 back in 1990. In 1985 the UN was predicting the Las Angeles, NY, and San Francisco was going to be under water due to ocean levels rising. The Great Barrier Reef was supposed to be gone by 2005 because of an increase in ocean temperatures. It's been going on for 40 years. Some panic that all the "kids" believe, and some of the older ones, it's repeatedly endlessly in the "news" press, and then people forget the predictions never happened. They've been doing this for 4 decades. And people are sick of it. At least An Inconvenient Truth was put on film, and you can see all the predictions there, and see how completely wrong they were. In it there was "the hockey stick", at which point, supposedly, the Earth would hit a runaway greenhouse effect, and it would get hotter and hotter every year, and it was the point of no return. Go see the film. It's all just bunk. In the 1970's the impending disaster was the Population Bomb, and get this - a new ice age. They REALLY said this. How many times do they have to be wrong before you realize they're just full of crap?
I think Al Gore must have been the only one who paid attention to this testimony. That being said it took him 15 years to make "An Inconvenient Truth", based on this testimony. Imagine parking a car on train tracks and expecting it to stop a train. That's where we're at.

@@thebackpainmiracle what is he lying about? Glaciers are melting, ice sheets are breaking, weather is changing, Egypt and Middle East used to be more fertile, we can use mathematical equations to determine temperate on another celestial object and then measure to determine if the maths are correct, and we could use with more long term thinking.

Especially considering the tremendous advancements made in nuclear power plant technology in the nearly 40 years since this speech was given, it’s a wonder there hasn’t been a bigger push to nuclear power as it is clearly the best solution we have to the problem outlined by Carl Sagan here. But I suppose nuclear just poses too much of a threat to the fossil fuel industry which would be poised to lose trillions of dollars if nuclear power is widely adopted, and we can’t have that can we?
@@xCrusader66x Yes, improvements made but this talk was also before 2 major nuclear accidents (Chernobyl & Fukushima) which have clearly demonstrated the risks involved.

Isaac Asimov, modest as he was, said Sagan was the only person he knew more intelligent than him. Here, intelligence also includes breath of knowledge.
a brilliant and woefully uninformed man 40 years, nay, 60 years in current scientific understanding in the past. No. The Earth did not boil over when the Chinese started using fossil fuels to power their half of the Eurasian Continent, and neither will it boil over when the Africans do. The atmospheric increase in greenhouse gasses has very little impact on the climate outside the equators. There is no scientific proof for a positive feedback loop. There is no observable data that points us in the direction of a climate disaster. Weather events are de-escalating. The earth is getting warmer, only natural considering we are exiting an Ice Age. for crying out loud.
I watched this Congressional session just after watching Carl give a Royal Institution lecture for children on another subject. He was able to pitch his delivery to such differing audiences without losing any of his message or its power.
There are more than enough competent astrophysicists and climate scientists nowadays. Actually, more than ever. What we need is more politicians who are willing to listen and journalists who are willing to take a step back and stop their superficial clickbaiting
@@vinvic1578 I absolutely agree but Sagan was a force of nature. The ability for scientists to make science in general exciting is easier than ever but you really don’t see this as much as we should. Having a middle man that can make complex ideas exciting and palatable for the public is essential.
We have people like him; it's just that now we have half of the political establishment working against them.and even vilifying them. Any attempt at addressing this has politicians scaring people about them "coming for your gas stoves".
To think there was a time when we had mature adults in Congress who listened when people appeared to speak to them and it was not all about party politics. I miss these days. They still didn’t get anything done, but at least they listened respectfully.
With Hurricane Milton bearing down on Florida at the moment Sagan's words about "if you don't worry about climate change now (1985) it will be too late later." Welcome to later climate denialists. Does your political ideology make you feel any better?
Whenever I read his words, see or hear him, it always provides a feeling of hope that humanity can sometimes produce great people that can lead the way to a better future for all.
Carl saved the best for last. The crux of the matter is when dealing with human beings who are so divided in their selfish goals, it is impossible to get meaningful cooperation on any level.
The fake news on social media increase the divide alot. Imho Just saw an article about a study published in Nature Scientific Reports (Coan et. al. 2021) We need to get people to detect the fake news. So we atleast can talk about the same facts/consequences. Quote from the article: "Last year, Cook released a free game that “vaccinates” people against fake news. A cartoon character called Cranky Uncle - representing conspiracy-prone uncles everywhere - uses his favorite techniques to teach you to become a science denier like him. In the process of learning how to create fake news, people learn how to spot logical fallacies and other techniques used to dismiss scientific evidence, like cherry-picking temperature data or citing fake experts. This approach, called “pre-bunking,” has been shown to be effective - playing a similar kind of game can reduce people’s susceptibility to misinformation for three months, one study found."

Except that greenhouse has a different physics (solid insulative material) to atmosphere (buffer with particles). It was not the first time where Sagan was wrong - eg. the Dragons of Eden regarding sleep and development of brain.
Carl Sagon was proscience but ironically sounded more prophetic than nearly any religious leader of every religion since. He even prediceted social media and the dumbing down of America decades before it happened. If you understand Sagan you will realize this country is now past the brink. We have elected the ultimate charlitan that will now use his power to further manipulate and control information being fed to Americans. With that ability every opposition will be futile.
Wrong. YOU control information by controller where YOU obtain your DATA. Trump will simply support the Fossil Fuel Narrative and line his and his cronies pockets from the TRILLIONS generated by the fossil fuel industry.. What the fuck are YOU doing to help fix this?
Towards the end of this testimony he uses the phrase "looking into the future"; something he had an uncanny ability to do. One of my all-time heroes, who still commands every mote of my respect. The world misses you Carl Sagan.
Some listened but there was little action. The IPCC was set up three years later to summarise the science to 'policymakers', but science alone with all its caveats was not as compelling or direct as Sagan or Hansen. It was clear then we need to end the fossil fuel era, it's clear now we can, if only public pressure can overcome malign vested interests in the minds of 'policymakers'.
Hahahaha, he didn’t look into the future, he just spoke out the agendas these rulers had been planned way in advance and that they told him to spoke out back then. Just like The Simpsons didn’t predict anything but just announced it to us. Wake up, people! Period.
It's funny to know that in a few years, without a place to live because of the climate change money becomes worthless, they want so much cash that in the end there will be no place to spend it.
Dear Lorenzo, Yes, you are pointing out to a substantial emissions source but friend people who can do something about it are not listening unless common people in huge numbers focus on the purely Kafkaesque scenario of conflicts and the associated weapons industry (or may be reverse, viz., conflicts arising out of the itch we humans gets once we put together some powerful weapons system ).
Back then, the present QAnon, alt-right, and self-described "Common sense conservative" types would have shouted "Nerd!" at you. For those not around back in 1985, then, 'nerds' on the youth social heirarchy were just barely above racial minorities (esp Blacks) and LGBTQS.
Good God I miss him. I can only dream of such a conversation today , such a respectful demeanor and the listeners being so equally respectful. You are missed Carl, we who read your books hope to follow your work.
@@anydaynow01 they wanted him there to scare the populace into going along with Carbon Taxes. Good Fuck Job. How is paying a tithe solving the climate crisis????
It just struck me that the Dr Ian Malcolm character (played by Jeff Goldblum) in Jurassic Park is without question based on Carl Sagan. Listen to the cadence and inflection of his voice.
However, author Michael Crichton was well aware that manmade global warming was nothing more than an alarmist myth, as described in his novel "State Of Fear". Carl Sagan may talk beautifully but he wasn't all knowing.
@@budstik should I shut up? Because I tell facts you don't want to hear? Carl Sagan may have been a great showman, but real scientists were never so enamored with him.
He points out how they’re saying “it’s not our problem”, and leaving big problems for future generation. And the senators thought “oh, that’s a good idea, let’s do that more”
4:14 - That guy, right there, wrote a book and made an award-winning film about climate change. If the Supreme Court hadn’t stopped the Florida recount in 2000, he also would have been our President and would have vigorously pursued policies to mitigate climate change. Instead, we got Dubya, whose administration forbade the mention of climate change in government documents.
Like the massive federal deficit....let's leave it for future generations to deal with. Who cares about government fiscal responsibility when the government can just print more money to cover their irresponsible spending, and they wonder why the US is facing extreme inflation and recession.
@@AlcHEMI_SRT honestly, I couldn’t care less about money. Seems a bit more important to take steps to ensure current and future generations can survive, have their rights, lives, and health protected from actually real threats. Climate change, disease, violence, homelessness. Those are more important than the economy, which only requires an agreement that it’s fine and suddenly it is, because that is only based on the fiction of money. Not to mention that it’s been demonstrated that when a government that actually takes care of people’s quality of life, the economy tends to improve as well, so by actually ensuring the former you solve the problems with the latter
When you think Carl Sagan was one of the most influential scientists of his era, that this speech took place openly before Congress and then realize that nearly 40 years later this had simply no significant effect on our governments, on our living modes and organizations and finally on ourselves, then you are entitled to feel a bit outraged, sad, frustrated, pissed-off, tired, disillusioned (pick whichever applies to you or add yours)…

Such a great speaker and communicator. His ability to explain this concept clearly and accurately has yet to be matched by anyone else I've heard so far.
He just explained how Venus has a greenhouse effect, even though it is impossible for Venus to have a greenhouse effect. Maybe it is not that the is a good communicator but a good deceiver.
@@EwwwYT It is impossible, because Venus has a dense atmosphere in super critical state, which allows only a very small amount of sun radiation to reach the ground and reflected, therefore it cannot cause any warming to the atmosphere. It is an example used frequently to deceive the masses, that know nothing about Venus.

I was almost 23 years old, in 1985, when I saw him speak about this topic to the USA government. It saddens me how, now at 62 years old, very little action has taken place towards alleviating climate change. 😢
AMAZING!!!!!!! I am in awe at the level of respect they're showing while he is talking, I forgot what that looks like when people to pay attention. Nobody's interrupting, being rude, sending out tweets, etc.
In the first moment I agreed. Then I saw the people in the background reading and not paying attention. We humans have a strong tendency to ignore desasters until a desaster knocks at or sits on our couch. This applies to personal, mental, health related, social, global matters etc. My interpretation is, that people were more polite back then.
His last point hit me so hard. When he was stressing the importance of coming together for a global awareness of Climate Change. Almost 40 years later and we aren't even close. Damn it Carl, we miss you.
Thats the thing, the world has come together, its just that the wealthy powerful people of the world have come together to make sure nothing gets in the way of them making money. They will continue to stop climate action because they are only concerned with their immediate profits, they could care less about the harm they are doing to this planet.
"His last point" was EXACTLY what we have today. An appeal for global elites to run the world for us and let us eat whatever crumbs & scraps that fall from their table. That is the ONLY reason he was the focus of this "Dog & Pony" show PAID FOR BY THE GLOBAL ELITES. "Almost 40 years later" and the temperate is fine, the ice caps are fine, "the massive rise in sea levels" is nowhere to be found and Obama spends 27 million $'s on a Beach front property as he leaves the Presidency and hands over environmental policy to Donald J Trump.
So "Almost 40 years later" the elites have got a wonderful return on their investment to make Lemmings out of a once free people who never pass an opportunity to demonstrate their counterfeit "wokness" and counterfeit virtue all the while funding these Global Elites with the labor of everyday Americans.
What a beautifully eloquent and succinct speech. He was without doubt one of the most charismatic and unique orators of our times. Rest easy Carl, you are deeply missed x

I wonder about many things. I was in my mid twenties when this meeting occurred. I was taught, during this time, to attempt to express my views in a reasonable and articulate way. This is what we see Carl doing. What happened since then? It is not my original thought, but it seems that social media has become the equivalent of scrawls on a bathroom stall. We may not always agree and that can be a great thing. It allows us the opportunity to take in different perspectives. So much has changed, most notably, in my experience, the extreme increase in population. It has doubled since I was born in 1957 and tripled since my mother was born in 1929. I feel we can stop trying to think we know what is going on and try to listen and act collaboratively.
I would add that it's not just social media, but the currently overly popular assertion that critical thinking is the equivalent of a web search. Oddly enough, in a speech to high school seniors in 2015, the CEO of Google made that exact assertion. While I was no longer a teacher, I still knew many who were at that meeting. They all told me the cringe among the teachers present was almost audible. We see this now in the overwhelming confirmation bias by people who have "done their research" by merely conducting a web search with a deliberately biased query designed (knowingly or unknowingly) to have a specific predetermined outcome, then claiming to have discovered the 'Truth' simply because it yielded what they'd expected to find in the first place. (i.e. classic confirmation bias)
Mr Sagan is the person that I always say "Who would you invite to your dinner party" when asked.. The gent made the complex simple and opened up the sciences for a generation and beyond, who may never have had the opportunity to explore it.. I am very serious about that statement.. He removed the sense of snobbery about science and made it real and dare I say.. cool.. for a generation and beyond, who may not have had the opportunity to be enlightened by what is out 'there'.. I am moved by his words that we are all star stuff.. Mr Sagan's words should be mandatory teaching.. Whatever your faith, creed, or background.. No one can deny, we are all part of one universe and we need to do everything possible to save it..
Brilliant, but not a climatologist and definitely wrong here on nearly every point. The data shows no significant change to the climate due to human activity. None.
I am bummed too. This whole greenhouse effect was established science for centuries even by 1985. Not decades, mind you, but centuries, with first speculations going all the way back to 1824, when Queen Victoria was a five-year old child. Yet, not much has changed. Hell, I'd even argue it's worse.
Al Gore has demonstrated through his actions that he understood this message and is willing to take risks against the Maga cult and Trump who believes that when it snows in New York, it is proof that global warming is a hoax ( his favorite word for anything that he disagrees with)
@@tenhovergonha8739 There is no church of science. Science is the absolute opposite of religion. Science is not about faith or belief. Science is about FACT
He would probably feel demoralised as to how his analysis was ignored. Instead, there has been hysteria and manipulation. As he said, it is a worldwide problem. A few countries taking action doesn’t solve it.
But did he mention possibility that emissions do nothing important while temperature patterns being driven by cyclically through cosmic cycles changing pressure in troposphere? ruclips.net/video/1Y_n283fYbc/видео.html This would change everything fundamentally. but this world is not driven by free scientific discourse anymore so you can't expect anything reasonable on this planet anymore either ;-) have a Great day
Carl was such an icon! His ability to communicate and simply explain complex scientific information to the general public was legendary.. I could listen to him for hours. Such a knowledgable and humble man. I wish he were here to add his perspective to todays scientific dialogue.
Indeed. If he was here, he could add something about plant absorbtion of atmospheric carbon. The fact that coal was actually created thanks to high CO2 concentration in the atmosphere. That it let various plants thrive to gigantic sizes. That the comparison to Venus is irrelevant because there is no biological CO2 cycle there. Then he could refer to deforestation along the equator, the tree-deprived concrete cities. Just a few details he seemed to have forgotten to mention at the time.
@@shamashelhashysh9159 Biological CO2? Interesting. I did a search on Wikipedia for biological CO2 and unsurprisingly, it says it does not exist. As far as I can tell, carbon dioxide is carbon dioxide. The atmosphere on Venus is 96.5% CO2. Scientists believe this was due to what they refer to as a runaway greenhouse effect. It's what happens when the shit really hits the fan and the effects are believed to be irreversible or at the very least, not expected to change for a very very long time. And as Sagan points out, some CO2 is a good thing. But just because there were times in Earths existence that higher CO2 levels were beneficial, such as the thriving flora you mention. It doesn't mean that the same amount of CO2 in the atmosphere would be good thing now. Conditions are vastly different. So your examples are kind of shitty.
A shame he had to go. Even more so in the manner Mr. Sagan left us. I would have been keenly interested in his thoughts on the sad state of affairs today.
But he IS here today... via RUclips to logically and clearly explain to us--current politicians and general public alike--the same brilliant info that is still relevant today! His Genius Mind immemorial lives in this vid through his image and voice. Thanks Google and RUclips❣️
This is a WORLD away from how this conversation would go in our recent Congresses where he’d be vilified and interrupted and face questions that have nothing to do with science or his expertise.

If, like Shakelton, he would have tried to travelled by ship, he would have had second thoughts, about melting the enourmous amount of floating sea ice blocking his travel to reach the place.
It's also important to understand business and politics was more sneaky back then, politicians may have been more polite in front of the camera, and the respect for scientists was bigger than it is now( also because of the scarcity of such science profiles compared to now) But in the end, nobody really cared and behind the scenes it was business as usual...

Carbon dioxide at 0.04% is a 2,500th part of the atmosphere. that means to warm the climate by just 1"c carbon dioxide molecules must capture 2,500"c of heat energy. That is impossible. It also breaks the fundamental laws of thermodynamics.
Methane at 0.00017% is a 600,000th of the atmosphere so it's even more impossible. To cause 1°c of heating methane would have to capture 600,000°c of heat energy. Problematic as this is over a hundred times hotter than the surface of the sun. (Methane rapidly breaks down in sunlight).
However, the climate is changing. This is because of deliberate geoengineering programmes, inparticular ozone thinning away from the poles. Though largely unreported ozone thinning effect is directly observable producing an unnaturally bright sun and even s bright moon. Under these conditions the pain felt when looking at the sun is not only from the increase in visible light but the much larger increase in infrared. (Look up at the sky and you will see a range of geoengineering operations in progress, these include chemtrail induced cloud or hazing, ripple patterns caused by HAARP installations, bizarre and unnatural cloud formations).
Climate change is a programme to force change in accordance with the implementation of agenda 21/2030. Current events demonstrate this transition is well underway and will involve massive population cull through injected nanotech (re transhumanist programme). Agenda 21 also sees the permanent loss of all property rights with the introduction of universal basic income (ref nesara/gesara) and has/is being promoted by the World Economic Forum.

I have included a debunking of 'accumulated heat' as it is so often used to explain how trace elements, so called 'greenhouse gasses', can warm the planet.
Accumulated heat whilst sounding a reasonable explanation of how heat can build up is rather nothing more than gobbledygook. In fact it shows those using such arguments do not even understand what heat is.
When we measure temperature we are measuring the heat energy a thing is losing. In short heat is a measurement of flow, the transfer of heat energy and this will always be in the direction towards the colder. For this reason a thing can never 'accumulate heat' in the way those advocating co2 climate change describe. The temperature of a body is the measure of heat output, it can never be greater than the measure of heat input. Output = input. When a thing is warmed it is heated to an equivalent of the heat input. If this input is not maintained it will cool. Those that propose that heat can build up to be hotter than the total measure of heat input at a given time either do not understand what heat is or are being deliberately misleading. To illustrate, an object being heated by a flame can never become hotter than that flame, it's temperature cannot rise inexorably to the temperature of the sun for instance. heat cannot be accumulated. When we think about it common sense tells us this must be the case.
Nasa and even nobel prize winning physicists have expounded 'accumulated heat' as the explanation how co2 is able to warm the atmosphere. They claim that over hundreds of years co2 has captured heat energy and this heat has 'accumulated' to produce a serious warming effect. As I have just explained, this is totally impossible and fundamentally violates all the laws of thermodynamics. That respected scientists should support such uneducated, unthinking nonsense is disturbing and only reflects that in terms of being able to think clearly about a subject they have no facility or inclination. These are the dark ages of science. Belief has outweighed logic or any critical thought. It tells us that we should not unquestioningly accept anything we are told, that experts can be fools.
(nb: Be aware of attempts to discard thermodynamics by talking about biology.
eg. 'it only takes a drop of arsenic to kill a person.'
This would be somewhat desperate, muddled thinking. clearly biological processes based on the reaction of a cell are not the same as the laws of physics/thermodynamics).
Continued...
It is impossible to trap more energy than the energy available. This is the first law of thermodynamics.
Furthermore, climate change models require that this heat must be from radiant heat from the Earth's surface. The reason this must be so is explained by the thought experiment as follows:
'Five photons of energy from the sun, one photon is absorbed by CO2. Does the planet warm more than if all five photons had hit the surface? '
Anything that captures radiant energy will in turn radiate 50% of its energy back to space. This is as much a point of logic. It is also easily proved by everyday experience. When a cloud passes overhead it immediately becomes colder, this is because radiant energy is absorbed by the water molecules and the same will be true of CO2. Carbon dioxide can only reduce surface temps though as I explained the proportion of CO2 is so fractional as to have any measurable effect. Clouds, and the fact that nights are colder than days, also demonstrates that Earth loses heat extremely quickly and shows the importance of surface heating from direct sunlight.
It also explains why all those peddling the CO2 climate hoax have to ignore infrared in direct sunlight. Were they not to do so the whole charade falls apart as it means half of all infrared energy from the Sun will be radiated back out to space. This is problematic as almost half of the Sun's radiant energy IS INFRARED!!!
... OUCH!
Fractional elements have fractional effects. We understand this in everyday common sense as proportion.
To imagine carbon dioxide can capture this magnitude of energy is absurd and breaks the basic law of thermodynamics. Were it so all energy needs could be solved through the magical energy capturing power of CO2.
There are many other fundamental problems with the CO2 climate change model. Eg that CO2 is highly soluble and is washed out extremely quickly in rainfall; that CO2 levels fluctuate drastically seasonally showing on earth with its high rainfall CO2 is not a gas that accumulates; that heat cannot be trapped in oceans as described in climate models as they are more 'energy dense' than the adjacent air, rather if oceans are becoming warmer it can only be from direct sunlight; that increasing biomass increases CO2 because it increases the carbon in cycle; that correlation is not causation otherwise it could be said daisies cause hot temperatures because there are more daisies when it is warm; that there is extremely dodgy Victorian science/politics behind Ice Ages which is never questioned or examined - eg mammoths despite claims otherwise are not adapted to cold but rather appear to be cold temperate animals similar to highland cattle, their blood is not antifreeze as claimed, they have no sebaceous glands, hair is long but sparse - even yaks being hairier, mammoth remains as far south as Mexico; that how can ice cores be an accurate record of the past if miles of ice have supposedly melted?; that Milankovitch Cycles mean that the Southern Hemisphere is currently in the middle of it's Great Ice Age; that the hypothesis that burning of forest subsequent to Ice Ages resulted in warming is logically inconsistent as 'no new carbon' has been introduced into cycle this all being carbon already in cycle and in any case would be washed out almost immediately; that CO2 levels are at a geological low; that the oxygen cycle is intertwined with the carbon cycle and dependent on it; that life is carbon based and CO2 is essential; that a halving of CO2 levels would result in the extinction of nearly all plant species - problematic as it in turn means theorised measures of atmospheric CO2 during Ice Ages cannot be correct - contrary there was a proliferation of megafauna; that alarmingly, plants already struggle to get enough CO2 for growth which is why farmers will often increase CO2 in greenhouses to promote yields; that the so called 'proofs' showing CO2 is able to capture radiant heat energy only prove the opposite and how very minor this is - that atmospheric concentrations of 0.04% CO2 thermal effect would be far too fractional to even be measured; that comparisons to other planets eg Venus/Mars prove CO2 does not capture the proportion of energy claimed and maybe this is why these comparisons are done less and less; that in order to explain vastly higher concentrations of CO2 in the geological past the sun is deemed to have increased its output this despite losing solar mass (gravitational mass) as fuel, this in turn meaning that the orbits of all the planets are all moving away from the sun - such hypothesis where solar activity is used to exactly compensate for holes in the CO2 climate theory is to ignore other evidential explanations of stars such as the 'electric universe theory'; that the geological archive shows periods of millions of years when CO2 and temperature were heading in opposite directions... etc).

Carl Sagan certainly was a great man and a great scientist. But it needs to be noted that he was a physicist, not a geologist or planetologist and certainly not a climatologist. We also got decades more of data and thought about this.
He failed to take into account the gas pressure on Venus and how the composition of gases would be unimportant due to adiabatic pressure and temperature. Else Mars, with an almost entirely CO2-atmosphere would have a similar greenhouse effect and temperatures.
Secondly he failed to take into account saturation. He correctly states that, if we saw the world in the absorption spectra, it would be black. Adding further absorbers is irrelevant when everything at 50microns already is absorbed, cause nothing more can be absorbed at these wavelengths.
So, this endorsement of a globalist fight against climate change should be discarded for the fundamental scientific failures Carl Sagan made in this speech, I am very sorry to say.
@@donaldduck830 Not sure which yahoo you got this information from but you've been duped. Compression of gasses (what you're calling adiabetic pressure) does indeed cause a temperature rise, but only when going from lower pressure to higher pressure. In contrast a lowering of pressure causes a sudden drop in temperature.
However the atmosphere of venus is not changing pressure. It's high pressure, but it's stable and unchanging. Thus there is no warming as a result of that pressure.
The high pressure of venus is relevant here because it means that the amount of total CO2 in the atmosphere is MUCH higher than just reading the composition would expect. As Carl Sagan correctly states, this is an extreme example and not the expectation for earth.
Mars is barely worth mentioning. While it is 95% carbon dioxide, the atmosphere is so thin that this is almost irrelevant to anything.
40 years later and there are still many humans who don’t believe climate change is real. His words fell on deaf ears and nothing has been done to address this issue. I am so glad he didn’t live to see the shocking weather events happening worldwide now. Still miss this incredible man, who tried desperately hard to warn us 😢
How do you, or how can you prove humans have been the major driver of climate change when the latest 10,000 years have been the most stable in earths beginning. And in the last 10,000 years have been a steady and very very slow change in temperature.
Because since the industrial revolution this very, very small change is no more smal but fing huge
I never knew Mr Sagan or met him. But I did watch his documentary Cosmos, all of it as an adult in the early 2000s. The cosmos was broadcast in Malaysia in early 80s. But some very "smart" tv program executive in Radio Television Malaysia scheduled it after my 8 year old bedtime at 10pm. So I did not see it in the 1980s. I got my first telescope in 2003 after watching the whole cosmos series and realizing I actually love astronomy. I wished I watched Cosmos in 1980s and made a different career choice but I made the most of the past 20 years. 😊, I am happy. Tq Mr Sagan. RIP

Carl Sagans unparalleled ability to communicate has me lamenting his death. He taught me more about learning and science than any other. We still miss his counsel we still need his clarity and I valued his incorruptibility among many other things. I wonder about what he'd have to say now. The prognosis for us wouldn't be good at all.
@Just think What a lunatic; come off of this crazy narrative. I'm no liberal or screaming "snowflake" but your incendiary and uneducated comment is just plain ignorance. When you take the time to learn the science of atmospheric science (meteorology) and then study basic chemistry and physics you will come to a new realization. Your weather isn't created for "your" or me by "God" or any other divine being; it's the process of the Laws of Thermodynamics when combined with the earths rotational movement, incoming solar radiation, and water. Speak when you can explain the process of a thunderstorm: how it forms, why and how there is lightning, and what makes hail and ultimately rain?! Then you will have a basis of knowledge that is demonstrable; not some trite dribble and passive, baseless insult. If you are so motivated, watch some videos of the brilliant Brian Cox (physicist, not athlete) for quick catch-up courses on science you seemingly missed out on. Good luck.
Guy McPherson, David Suzuki, and Bill Nye are among the climate scientists carrying on what Carl Sagan explained in those days. They are described as "doomists".

This might be the smartest and most effective summary of the climate crisis you can find on the internet. Incredible that the entire diagnosis of the problem, the solutions and the obstacles in the way were evident all the way back in 1985 and yet we have still failed.
I really feel as though Jeff Goldblum based his portrayal of Ian Malcolm in Jurassic Park on this man - and added in some rocket-fuel rockstar charisma for good measure. The voice tone and pitch height, and the use of prosodic stress, are a near-perfect match.
Carl Sagan was a very good scientist, but most importantly, he was an extraordinary communicator; he really uses his voice like a Juilliard-trained actor, draws his audience in, and this gives his words a weight and a sincerity that is unmistakable as well as impossible to ignore.

Carl Sagan was also a consultant on the 1984 movie "Threads", about the threat of nuclear arms. It is, by far and bar none, the most frightening movie I have ever seen. He was literally trying to save the world, one measured word at a time.
And in the process set back energy efficiency for decades. His negative effect, therefore, on emissions of greenhouse gasses is massive.
but these were not issues until he brought them up. almost as if he was giving them the ideas.

@@imshaunnurse "but these were not issues until he brought them up" That is not how reality works.
@@ballparkjebusite After nuclear energy started making headway and actually improving our energy infrastructure, the Left took a stance against it. They purposely conflated two separate issues, nuclear weapons and nuclear reactors, into one umbrella item to be an activist against. The average person likes to feel like a concerned citizen but at the same time has extremely little knowledge of either "nuke". The result was no growth in reactors since the 80s. Of course, our energy demand didn't shrink an iota, so the shortfall of not having nuclear energy meant extra pollution from coal or gas plants. Thanks Carl.

I’m trying to imagine him trying to talk with the likes of today’s congressional members … and they’re climate denial jeers & heckling. 😳
This was the calmest climate change talk I’ve ever heard. I think laying out the facts in a more objective way like this is so important, people can only grab onto the facts
Exactly why it's not like that anymore. One side doesn't want facts to be grasped, so they yell and scream and distract.
I'm a big fan so scientific objectivity, but thinking facts alone will convince people is sometimes criticised as the 'deficit model'. Unless you are more motivated to learn and understand than you are to protect them perceived interests of your community, you may ignore or reject uncomfortable knowledge however you can. See Sagan in 1990 on Croesus versus Cassandra and how relating to climate change 'denial is not just a river in Egypt'. There's also a famous quotation of his about how painful it's is to admit you've been bamboozled by charlatans. So there need to be honest channels of communicating besides facts. You might be interested in Prof Katherine Hayhoe's book "Saving Us" about the importance of bonding and finding common ground with people and inspiring them with effective climate action. It seems many people whose political tribe or personality compels them to remain silent on global threats still see the local benefits of wind power and EVs.
If facts aren't the problem, why am I writing all this :)

@@davedixon2068 And there are still people selling sand to ostriches. Surveys show (Yale Six Americas) most people aren't like that. The majority are concerned, but want to know what to do. Sagan's answers to that are broadly still correct, but other experts (like Mike Berners-Lee and Katharine Hayhoe) are a bit more up-to-date.
@@davedixon2068 That's an optimistic view. For every person doing the 'LALALA', there are 3 people who are so over their heads working 3 jobs to make ends meet they have no time to consider the future, and 1 person screaming 'trans - culture war - witch hunt - woke - great replacement - child abuse - baby killer - fascist' at everyone they meet, whilst engaging in or supporting at least one of the things they are screaming at others about.
When those last people manage to elect an immature narcissist to 'the leader of the free world', alongside other countries where they don't even elect their own less immature and more deadly narcissist dictators, there is not a hope for real consensus to deal with the most important problems - they are less important than feeding the endless void of such leaders.

I read his book, Cosmos, as a young teenager and it influenced me to study science at university. While I did not turn out to be a natural scientist, I’ve remained very interested in these issues. It seems now that we tend to hear from politicians or activists but rarely from people so reasonable as Sagan.
Because everything that has to be said has been said. We need action now. Policians do what is popular with the citizens. But citizens are stupid. So a few activists try to press the issue. But most of them are stupid too, so they overshoot, asking for too much, resulting in the general population being less fond of the topic, resulting in politicians doing less. We're doomed.

@@inanitas bugman demoralized into not perpetuating his own bloodline. Another success for globalist propaganda
I just need to know what the Kardashian’s are doing.
If Mr. Sagan was alive today, I can't imagine how discouraged he would be in seeing how little has been done to fight this global threat, due in no small part to the massive resistance by those who benefit from the continual poisoning of this planet, and those who so readily believe them.
People have generally been pretty good at reacting to an immediate threat like Pearl Harbour or a killer virus. Long term threats though we are not geared up well to deal with, most governments think only in terms of the next 5 years of their term, also the fossil fuel industry obviously out a lot of effort into delaying or denying need for change.
And he would be embarrassed by how goofy the environmentalism has gone.
You have no idea what you're talking about. And I feel very sad for you. You falsely believe our planet is dying based off of a faulty understanding of the impacts of global warming. I mean this from my heart because if I believed the incorrect popular narrative, I, too, would be shitting my pants

Carl was such a great communicator, and shockingly prescient in his analysis.
tthats why is show COSMOS was so popular in the 1970's
He only repeated the propaganda, nothing special.
Also most predictions done back then when the science itself was fairly new and with far less computing power than today has been spot on. And Sagan's quotes nails it, he foresaw everything that's happening today, including the anti science "don't look up" crowd.
Edit: This one:
“I have a foreboding of an America in my children's or grandchildren's time -- when the United States is a service and information economy; when nearly all the manufacturing industries have slipped away to other countries; when awesome technological powers are in the hands of a very few, and no one representing the public interest can even grasp the issues; when the people have lost the ability to set their own agendas or knowledgeably question those in authority; when, clutching our crystals and nervously consulting our horoscopes, our critical faculties in decline, unable to distinguish between what feels good and what's true, we slide, almost without noticing, back into superstition and darkness...

Carl Sagan has been dead for over 25 years, and our society is still playing catch up with many of this amazing man’s thoughts.
We will be for centuries to come, if we make it that far.
These were not his thoughts, he's merely reporting well known scientific facts at that point in time.
All that's changed is we've learned there isn't a run away greenhouse effect, although our stupid governments keep promoting it. It's just another power grab.
Carl Sagan was certainly amazing, his thoughts in 1985 spell out the irresponsibility that was put on-ice back then, and is now resurfacing today in 2022 is a testament to the criminality of capitalism. It displays our willingness to destroy this planet many times over then shrug like dumb monkeys about what happened. Perhaps it is a blessing to be an ancient and deceased civilization because our bones and decomposed bodies will not create the lakes of underground oil that the flora and fauna of the dinosaurs did. A future society will have to consider non-fossil fuel sources in order to survive. That is, if they ever get another chance like ours.
@@TheMPBailey "Climate changed" has NEVER been "put on ice". Every few years, our propaganda "news" media predicts eminent collapse of the environment that nearly every single kid between 13 and 23 believes is about to happen, and in about 10 - 15 years.

In 1985 the UN was predicting the Las Angeles, NY, and San Francisco was going to be under water due to ocean levels rising. The Great Barrier Reef was supposed to be gone by 2005 because of an increase in ocean temperatures.
It's been going on for 40 years. Some panic that all the "kids" believe, and some of the older ones, it's repeatedly endlessly in the "news" press, and then people forget the predictions never happened.

And people are sick of it.
At least An Inconvenient Truth was put on film, and you can see all the predictions there, and see how completely wrong they were.
In it there was "the hockey stick", at which point, supposedly, the Earth would hit a runaway greenhouse effect, and it would get hotter and hotter every year, and it was the point of no return.
Go see the film.

The atmospheric increase in greenhouse gasses has very little impact on the climate outside the equators. There is no scientific proof for a positive feedback loop. There is no observable data that points us in the direction of a climate disaster. Weather events are de-escalating. The earth is getting warmer, only natural considering we are exiting an Ice Age. for crying out loud.

In the process of learning how to create fake news, people learn how to spot logical fallacies and other techniques used to dismiss scientific evidence, like cherry-picking temperature data or citing fake experts.

Back then, the present QAnon, alt-right, and self-described "Common sense conservative" types would have shouted "Nerd!" at you. For those not around back in 1985, then, 'nerds' on the youth social heirarchy were just barely above racial minorities (esp Blacks) and LGBTQS.
Good God I miss him. I can only dream of such a conversation today , such a respectful demeanor and the listeners being so equally respectful. You are missed Carl, we who read your books hope to follow your work.
Being addressed so civilly is mind blowing, and being allowed to speak fully.
@@anydaynow01 they wanted him there to scare the populace into going along with Carbon Taxes. Good Fuck Job. How is paying a tithe solving the climate crisis????
How many years we did nothing .....
and so much bs coming out of his mouth
a whole bunch of nosense by Carl Sagan, what a disGrace.
It just struck me that the Dr Ian Malcolm character (played by Jeff Goldblum) in Jurassic Park is without question based on Carl Sagan. Listen to the cadence and inflection of his voice.
However, author Michael Crichton was well aware that manmade global warming was nothing more than an alarmist myth, as described in his novel "State Of Fear". Carl Sagan may talk beautifully but he wasn't all knowing.
@@bigverybadtom do you ever shut up?
@@budstik Yes, when the other person does. Is it wrong for me to say that what Carl Sagan said isn't gospel?
@@bigverybadtom no you're suggesting the exact opposite and will not shut up about it.
@@budstik should I shut up? Because I tell facts you don't want to hear? Carl Sagan may have been a great showman, but real scientists were never so enamored with him.
It's so sad seeing him argue in good faith while the entirety of congress has no intention of listening or acting on what they hear
He points out how they’re saying “it’s not our problem”, and leaving big problems for future generation.
And the senators thought “oh, that’s a good idea, let’s do that more”
4:14 - That guy, right there, wrote a book and made an award-winning film about climate change. If the Supreme Court hadn’t stopped the Florida recount in 2000, he also would have been our President and would have vigorously pursued policies to mitigate climate change. Instead, we got Dubya, whose administration forbade the mention of climate change in government documents.
Like the massive federal deficit....let's leave it for future generations to deal with. Who cares about government fiscal responsibility when the government can just print more money to cover their irresponsible spending, and they wonder why the US is facing extreme inflation and recession.
@@AlcHEMI_SRT honestly, I couldn’t care less about money. Seems a bit more important to take steps to ensure current and future generations can survive, have their rights, lives, and health protected from actually real threats.
Climate change, disease, violence, homelessness. Those are more important than the economy, which only requires an agreement that it’s fine and suddenly it is, because that is only based on the fiction of money.
Not to mention that it’s been demonstrated that when a government that actually takes care of people’s quality of life, the economy tends to improve as well, so by actually ensuring the former you solve the problems with the latter
When you think Carl Sagan was one of the most influential scientists of his era, that this speech took place openly before Congress and then realize that nearly 40 years later this had simply no significant effect on our governments, on our living modes and organizations and finally on ourselves, then you are entitled to feel a bit outraged, sad, frustrated, pissed-off, tired, disillusioned (pick whichever applies to you or add yours)…
Why would I feel any of that because it’s all bs

Such a great speaker and communicator. His ability to explain this concept clearly and accurately has yet to be matched by anyone else I've heard so far.
He just explained how Venus has a greenhouse effect, even though it is impossible for Venus to have a greenhouse effect. Maybe it is not that the is a good communicator but a good deceiver.
@@GeorgiosD90why do you believe that it is impossible for Venus to have the greenhouse gas effect?
@@EwwwYT It is impossible, because Venus has a dense atmosphere in super critical state, which allows only a very small amount of sun radiation to reach the ground and reflected, therefore it cannot cause any warming to the atmosphere. It is an example used frequently to deceive the masses, that know nothing about Venus.
@GeorgiosD90 it's impossible? It's proven fact that it does, so I'd be very interested in your take and can't wait to congratulate you on your Nobel prize
@@readysetcomedypodcast1341 It is impossible for Venus to have a GHG effect, as it has very low sun radiation reaching the surface and proving it is simple physics no nobel price is necessary. Check it out for yourself.
This guy is talking out of his ass about things he doesnt know of.
I was almost 23 years old, in 1985, when I saw him speak about this topic to the USA government. It saddens me how, now at 62 years old, very little action has taken place towards alleviating climate change. 😢
And there has been no man made global warming. None. His theory, based as it was on ignorance of the workings of the climate, was completely wrong.
AMAZING!!!!!!! I am in awe at the level of respect they're showing while he is talking, I forgot what that looks like when people to pay attention. Nobody's interrupting, being rude, sending out tweets, etc.
In the first moment I agreed. Then I saw the people in the background reading and not paying attention. We humans have a strong tendency to ignore desasters until a desaster knocks at or sits on our couch. This applies to personal, mental, health related, social, global matters etc. My interpretation is, that people were more polite back then.
They've probably fallen asleep. This man is a terrible communicator.
👍I lived through so many endings of earth in my life. The politicians selling BS certainly was done differently back then.
@@thinkingimpaired5663 Carl Sagan was never a politician. He was a scientist and a very good communicator.
Our culture has radically changed.
our government needs to be filled with people like this, not former corporate lawyers and executives.
His last point hit me so hard. When he was stressing the importance of coming together for a global awareness of Climate Change. Almost 40 years later and we aren't even close. Damn it Carl, we miss you.
Careful what you wish for.
WEF/Davos billionaires/club of Rome/IPCC “sustained development”-UN agenda 21/30.
Thats the thing, the world has come together, its just that the wealthy powerful people of the world have come together to make sure nothing gets in the way of them making money. They will continue to stop climate action because they are only concerned with their immediate profits, they could care less about the harm they are doing to this planet.
@@knutz7 I support the U.N. agendas - you should too!
"His last point" was EXACTLY what we have today. An appeal for global elites to run the world for us and let us eat whatever crumbs & scraps that fall from their table. That is the ONLY reason he was the focus of this "Dog & Pony" show PAID FOR BY THE GLOBAL ELITES. "Almost 40 years later" and the temperate is fine, the ice caps are fine, "the massive rise in sea levels" is nowhere to be found and Obama spends 27 million $'s on a Beach front property as he leaves the Presidency and hands over environmental policy to Donald J Trump.
So "Almost 40 years later" the elites have got a wonderful return on their investment to make Lemmings out of a once free people who never pass an opportunity to demonstrate their counterfeit "wokness" and counterfeit virtue all the while funding these Global Elites with the labor of everyday Americans.
What a beautifully eloquent and succinct speech. He was without doubt one of the most charismatic and unique orators of our times. Rest easy Carl, you are deeply missed x
Congress: (i have no idea what all this means)
Congress: “it’s not our problem”
you people are naive and gullible, do you know how much carbon dioxide is in the air? take a guess, i'll tell you right now that at .02% carbon dioxide in the atmosphere, plantlife starts dying off! we have .04% carbon dioxide in the atmosphere today, we went from .03% to .04% in 60 years, and bounce back and forth between those two numbers, and this isnt my opinion, or theory, this is solid 100% fact, and science, we are in no danger of climate change, not for a long time yet, do you people realize that 7.8 billion people will fit in a state the size of new york? we are still pretty insignificant to this planet, what is messing things up is the poisoning of the oceans with radiation, and the removal of sand from our oceans, this is causing 1000 times more problems than andy climate issues, and it doesn't help you have our governments let whoever play with weather manipulation, the human species is stupid!
I wonder about many things. I was in my mid twenties when this meeting occurred. I was taught, during this time, to attempt to express my views in a reasonable and articulate way. This is what we see Carl doing. What happened since then? It is not my original thought, but it seems that social media has become the equivalent of scrawls on a bathroom stall. We may not always agree and that can be a great thing. It allows us the opportunity to take in different perspectives. So much has changed, most notably, in my experience, the extreme increase in population. It has doubled since I was born in 1957 and tripled since my mother was born in 1929. I feel we can stop trying to think we know what is going on and try to listen and act collaboratively.
I would add that it's not just social media, but the currently overly popular assertion that critical thinking is the equivalent of a web search. Oddly enough, in a speech to high school seniors in 2015, the CEO of Google made that exact assertion. While I was no longer a teacher, I still knew many who were at that meeting. They all told me the cringe among the teachers present was almost audible. We see this now in the overwhelming confirmation bias by people who have "done their research" by merely conducting a web search with a deliberately biased query designed (knowingly or unknowingly) to have a specific predetermined outcome, then claiming to have discovered the 'Truth' simply because it yielded what they'd expected to find in the first place. (i.e. classic confirmation bias)
I agree about population increases.
" I was taught, during this time, to attempt to express my views in a reasonable and articulate way. "
That’s why population control is needed. Too many leeches in society with low IQ’s
@@kenadams5504 that's not something people "agree" on. it's a fact.
Mr Sagan is the person that I always say "Who would you invite to your dinner party" when asked.. The gent made the complex simple and opened up the sciences for a generation and beyond, who may never have had the opportunity to explore it.. I am very serious about that statement.. He removed the sense of snobbery about science and made it real and dare I say.. cool.. for a generation and beyond, who may not have had the opportunity to be enlightened by what is out 'there'.. I am moved by his words that we are all star stuff.. Mr Sagan's words should be mandatory teaching.. Whatever your faith, creed, or background.. No one can deny, we are all part of one universe and we need to do everything possible to save it..
I would invite jesus, I only have one fish and one loaf.

Brilliant, but not a climatologist and definitely wrong here on nearly every point. The data shows no significant change to the climate due to human activity. None.

Is anyone else bummed this happened in 1985 and we are where we are right now? Just me?
Nobody wants nuclear. So no, it makes sense. Not bummed at all.
The Generation in political and economical leading position at this times and even today are just a effing disgrace
He said the effects would really be apperent around this (right now) time but he gave our species too much credit and said the mid to late 21 century.
I am bummed too. This whole greenhouse effect was established science for centuries even by 1985. Not decades, mind you, but centuries, with first speculations going all the way back to 1824, when Queen Victoria was a five-year old child. Yet, not much has changed. Hell, I'd even argue it's worse.
Not just you but he changed some peoples minds at least.
Imagine every senator and politician being this brilliant, objective and factual
Imagine a comments section with no PR reps
Al Gore has demonstrated through his actions that he understood this message and is willing to take risks against the Maga cult and Trump who believes that when it snows in New York, it is proof that global warming is a hoax ( his favorite word for anything that he disagrees with)
Intergenerational is too right. Here I am 40 years later, still concerned about the same thing as Carl Sagan, and progress is too slow.
He was a great communicator of science, and he is sorely missed. R.I.P. Carl.

carl was on the dope most of the time
I wish we still had Carl with us today. The world lost a kind and thoughtful and brilliant man when he passed
He would probably feel demoralised as to how his analysis was ignored. Instead, there has been hysteria and manipulation. As he said, it is a worldwide problem. A few countries taking action doesn’t solve it.
But did he mention possibility that emissions do nothing important while temperature patterns being driven by cyclically through cosmic cycles changing pressure in troposphere? ruclips.net/video/1Y_n283fYbc/видео.html This would change everything fundamentally. but this world is not driven by free scientific discourse anymore so you can't expect anything reasonable on this planet anymore either ;-) have a Great day
He is a shit talker,
Some numb skulls would have started conspiracy theories about him call him a devil and all sorts of bullshit names .
@@GuardianApe I see another shit talker
For some reason, even if you do not listen actively to Carl and have it in the background, he still has a soothing effect on your mind
Until you listen to his words and then read present-day headlines.
Carl was such an icon! His ability to communicate and simply explain complex scientific information to the general public was legendary.. I could listen to him for hours. Such a knowledgable and humble man. I wish he were here to add his perspective to todays scientific dialogue.
Indeed. If he was here, he could add something about plant absorbtion of atmospheric carbon. The fact that coal was actually created thanks to high CO2 concentration in the atmosphere. That it let various plants thrive to gigantic sizes. That the comparison to Venus is irrelevant because there is no biological CO2 cycle there. Then he could refer to deforestation along the equator, the tree-deprived concrete cities. Just a few details he seemed to have forgotten to mention at the time.
He is here now. I just watched him. He will always be here. People just need to listen.
@@shamashelhashysh9159 Biological CO2? Interesting. I did a search on Wikipedia for biological CO2 and unsurprisingly, it says it does not exist. As far as I can tell, carbon dioxide is carbon dioxide. The atmosphere on Venus is 96.5% CO2. Scientists believe this was due to what they refer to as a runaway greenhouse effect. It's what happens when the shit really hits the fan and the effects are believed to be irreversible or at the very least, not expected to change for a very very long time.
And as Sagan points out, some CO2 is a good thing. But just because there were times in Earths existence that higher CO2 levels were beneficial, such as the thriving flora you mention. It doesn't mean that the same amount of CO2 in the atmosphere would be good thing now. Conditions are vastly different. So your examples are kind of shitty.
A shame he had to go. Even more so in the manner Mr. Sagan left us. I would have been keenly interested in his thoughts on the sad state of affairs today.
But he IS here today... via RUclips to logically and clearly explain to us--current politicians and general public alike--the same brilliant info that is still relevant today! His Genius Mind immemorial lives in this vid through his image and voice. Thanks Google and RUclips❣️
This is a WORLD away from how this conversation would go in our recent Congresses where he’d be vilified and interrupted and face questions that have nothing to do with science or his expertise.
In my humble opinion this man was beyond genius. He has not only high intelligence and critical thinking but common sense. He is well versed on science and history. He is so sorely missed.
@@dunravin Dr. Sagan's IQ was 170 this places him in the genius range. This is less than 2 percent of the population. Yes i agree he was human and flawed.

Unfortunately his remarks are speculative, not backed by measurements and calculations, which require enourmous computing power and verifications locally, like the antarctic ice temperature is -50C , extremely dry, no sun in the winter , how is a rise of a few degrees going to melt the ice. If, like Shakelton, he would have tried to travelled by ship, he would have had second thoughts, about melting the enourmous amount of floating sea ice blocking his travel to reach the place.
It's also important to understand business and politics was more sneaky back then,
politicians may have been more polite in front of the camera,
and the respect for scientists was bigger than it is now( also because of the scarcity of such science profiles compared to now)
But in the end, nobody really cared and behind the scenes it was business as usual...
That was 1985?! I’m in awe of this man, and infinitely saddened by 40 lost years.
more than 40 years. the first outcries were in 1970. saddened to this day. we all knew better and didnt care or didnt have the power to do anything about it. need more objectors, at least. thank you for objecting
How did we lose 40 years? We are richer, we have more technology, better manufacturing techniques, and the climate is still good, polar bears are thriving. There still is a lot of time, especially so if we switch to nuclear energy. So I do not agree at all that we lost 40 years
