- With forests burning, rivers vanishing and continents carved up by toxic oceans, a world where global temperatures have risen by six degrees would be a bleak one - and almost no environment could sustain human life.

Climate Change may suck, but think of all the Shareholder returns we are generating.
3 to 5 billion people would die by between 2300 and 2500
@@nickallen6460 BUT THE PROFITS
That's what should be played on every channel on TV, every hour of every day, until everybody knows the consequences of ignoring the trend towards a hotter Earth. Instead people are feigning all sorts of accolaides on a quarterback for setting a new passing record, or shoving people aside to buy some garment Kim Kardashian endorses.
We can't stop it at this point, the ones that face truth know already, the others live in imaginary constructs
hotter earth is better ..
precisely!
But that way how would Kim K and all those companies selling useless crap get richer? 😂
..... and agonising over this weeks hair colour. Raspberry or lime ????
Decisions decisions. ..... What to do !
A 6 degree world is an extinct one. So is a 4 degree world, for that matter.
+ 2 degrees will already lead to human mass extinction in the globals south. Its happening right now.
Bullcrap. Different, but in no way extinct. It’s been way warmer in the past.
Extinct? Not surely, but definitely at least very close to it with only few people who might survive.
A slight chance but it's there.
Whoever doesn't quite understand the implications gotta watch national geographic "evacuating earth" episode 4 which describes the spiral effect and show some great visuals of what will actually happen.
I saw it years ago and saw it now again. It should wake up some people. And as for what we can and should do is mostly choosing our politicians based on their actions against climate change, otherwise we're probably doomed. There's a great vid about that in Kurzgesagt's channel. If we didn't emit any CO2 ourselves our entire life we would halt one lonely second in the heating effect..
4 degrees is probab;y survivable tbh-well survivable on a collective scale. A LOT of people would probably die in that scenario.
@@kruse8888 In the past? Like that one time almost all life was wiped out?
But if we try to prevent this the economy might not grow 1% more 😭😭😭
Yes of course, because the economy will grow so much more if we let all this happen.
@@Rejoran woosh
Man. What? Preventing the apocalypse>Economy
@@Redditorage It was sarcasm
Business as usual might have to take some real risks…
Kind of interesting the correlation between a human body and the world. Only a few degrees up, and both become incredibly sick.
I've been pointing that out to people since the 90's.
That’s awfully scary jinx
Still heading for this world in 2022, the beginning of the end, humans are in denial or insane
Reading some of the recent comments, I would say people are absolutely in denial. This is now the projected path.....
Let's keep the corporations profitable because that's way more important than this.
Corpses won't get a chance to pile up because people will be hunting and eating each other.
No they won't. Because the Earth will be such an inhospitable place that they woukd rather starve to death than stay longer.
Wouldn't be the first time. Cannibalism is an ancient practice.
By the time it gets this bad the population would have been reduced to small bands of survivalists and enclaves of the morbidly rich partying down in their secure bio-domes. These will be the last to go. But on the upside: small numbers of billionaires would have broken quarantine and made the journey to Mars, and would already be well on track to destroying the Red planet. This is why we can't have anything nice. It's also why ETs have been avoiding earth like the plague.
Dan Kelly I’m pretty sure the vegetarians be piled up for the carnivores to feed on
people will be eating the corpses!
Welp, it's great beeing optimistic but here... lets just say it: we're fucked.
Only if your a climate vulnerable primitive like most countries.
Sky lit of fire with explosions more powerfull than nukes. Something to look forward at the end of my life.

Happy new year that year. Nice fireworks i guess
we're gonna have a great retirement in 50 years
This video is NOT for the faint of heart. This is a video for someone that has already come to terms with climate change and wants to understand what is at risk.
The only 'problem' with this video is it reports methane being 20X more potent than CO2. That is correct when considering methane (CH4) warming over 100 years. The thing is, CH4 is 100x more potent than CO2 in a 2 year period. A large release (look up Siberian Times and search methane) of CH4 has substantial and immediate impacts.
The problem is even methane do not act like a GHG...
I'm faint-hearted.
And now.....Siberia is on fire.
@@WadcaWymiaru Please take note that this person does not understand physics and does not understand the principles behind climate change. Either a paid troll or a FOX/alt-right 'educated' fool that should learn to keep their mouth shut when they don't have anything productive to contribute. Mother probably raised them wrong :-/
CH4 is quickly converted to CO2 +
I wish global warming was a hoax. In fact never in my life have I wished so much to be wrong about something.
Its not!!! the warning were places on the sholders of Lynden B Johnson and every president long ago. Earth is heading into another mass extinction. co2.earth is the current co2 level
It is real!
Say hello to Venus
No GHG effect on this planet.
This is how the world will end.
I’m grateful to have been part of one of the last generation of humans to have lived. Let that statement sink in for a sec.
Maybe not extinction, but a reduction of population, massive wars and terrible suffering.
this is bs
Humanity will be alright as long as it turns civilised in time and stops being a bunch of variable, primitive, fossil fuel burning barbarians who need to be colonized.
why?
Thats stupid, humans arent going anywhere from climate change alone
How do I not have anxiety attack after this information
Accept it
It is what it is
I dunno? lol!
I think existential threats are supposed to make us anxious, I guess we should do everything in our power to avoid them (but that won't necessarily stop our current anxiety).
At the current pace of warming and social and political inaction, the Earth is on pace to reach a 5 degrees Celsius increase by 2100.
As a species we are to greedy and terratorial this will be our downfall
The good news is after the humanity disappears there will be way less morons on Earth
That was depressing
Well in the short term methane is almost 80 times as bad as CO2. And the thing is if the grain crops fail for two or three seasons then the fact that methane is short lived in the atmosphere doesn't matter for 90% of humanity.
Exactly, the short term goal needs to be getting rid of methane as it’s so much stronger, and then the long term goal is co2. Very scary times
we are doomed
This was made seven years ago, we are all failures
Every company and every nation needs to be putting all their resources into capture technologies that can capture CO2 and Methane. Its our only hope now.
Either that or some massive electro chemical process to vent GHG out of the atmosphere. Course the greedheads aren’t going to allow any of that.
None of those technologies work in the long term nor are sustainable, to recapture all the CO2 emmitted we would need to undo the whole process as carbon laying around would simply decompose back into CO2 eventually, so we must put it back into the ground in a form of goo or oil, aka reversing what we did; which is a harder process than extracting.
That's the bleak thing about climate change, it's unstoppable; carbon capture is a lie from big oil.
we really need to reassess where we are going as a species. The problem is, these issues are global but we don't have a global government to meet them so anything we do is usually disjointed and of a small scale. The future is bleak unless we can get a handle on this over the next few years
The flooding events and the extreme heat waves all over the world now baffle even the experts. Methane is being released as we speak (explosion craters in Siberia) but a real catastrophic release is considered very unlikely, again by the experts. Ironically the 'my freedom above all' lovers would have to accept that only a technocratic authoritarian socialist world government could handle such global disaster where people would have to move from country to country without any freedom of choice.
Basically we need the new world order to crush all conventional civilization in WW3

DeNile is a river in Egypt. And that is drying up.
it's drying up because of pollution, sewage & up river dams.....& an increase in population.
nothing to do with bullshit 'climate change'.
Nev Sagiba and many more rivers will dry up. It’s called water evaporation. The sun’s heat heats up H2O in liquid form, changes it to a gaseous state ... into water vapour. And away it flies into the sky ... somehow joins others and fall down as rain at a precipitation point. It’s apparently just part of life. But climate scientists have yet to confirm whether this is a theory or fact. By 2049 they will have an answer. 12 months before the sky totally falls on us all
@@jennsmith6212 your apathy is despicable mate, make no mistake that millions, if not billions of people 'will' die as a result of climate change, islands and coasts will disappear, hotter regions will become uninhabitable.
That's because we're in de-nial.
By 2100, we could reach 7 degrees Celsius of temperature rise. Presumably unlike when this visual was first given, in the world, it is now an implication, logistically, excluding.
We've already given up hope on holding to 1.5 and now 2.0 is a 'goal' to reduce the inevitable global civilization level of disaster. Incredible the outright stupidity of humanity. We gleefully run into the fire with optimistic hopes of futures that will never be. Yippee!
7 degrees seems like a stretch (or so I really damn hope). I'm expecting 3-4 if nothing happens until 2050, but if there's actual movement, probably 2-3. As much as I hope, there probably is no hope for anything below 2.
Hey, we officially reached 2 degrees celsius yesterday in 2023! 7 degrees in 2100 isn't a stretch at all, in fact it may be an underexaggeration
As of now new "hot models," climate models that predict much higher warming, have been doing better at predicting weather events and seem more accurate. There are climate protesters self-im#######ng, and still there has been almost no change. @@starryescapade5254
Sounds like a planet around another star, not our life haven!

If this should happen humanity deserves to be eradicated.
Yes with such horrible evil things as feminism, they deserve it.
TheCherry1994 YES
id prefer a nice quick explosion or something but i mean that probably wont happen so this is fine
That's wrong. Humanity doesn't deserve to be eradicated because the earth warmed. Humanity certainly doesn't deserve to be eradicated from greedy people pumping Co2 into the atmosphere.
Your telling me that people who have nothing to do with what’s happening to the earth should be eradicated?
During WW2, nations were spending 40%+ of their GDP on the military (normal spending is about 2-3%).
If we spent 2% of global GDP on renewables we could probably be at zero carbon by 2050.
For fak sake of GHG effect was proven wrong?
@@WadcaWymiaru I guess those unprecedented fires all around the world, despite us being waaaaaaaaaaaay more technically advanced compared to 100 years ago, are just a fluke. "Huh, must be nothing" - Wladca

Instead of having this on the news,we hear gossips about Harry and Megan
Let’s see.
* The first Blue Ocean Event is within 10 years.
* The Thwaites Glacier should finally fall before then.
* The Boreal Forests should have some serious issues around then.
* Greenland will further slow the AMOC by then.
* Antarctica melting should accelerate by then.
* The next El Niño could start around then.
* I know I’m leaving some things out but I don’t want to sounds alarmist.
Then the 2040’s sure ain’t looking pretty. The pain spreads everywhere.
And in 2,100 Earth Could be at 8-10 Celsius. So whoever is unlucky enough to be in a bunker will have to stay in that bunker.

- The sixth extinction is real.
Extinction rates (1500-2009) peaked around 1900 at 50 per decade. Extinction rates have declined dramatically to around 4 to per decade in the 2000s. So extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years (IUCN), so from observations there are an average of slightly less than 2 species lost every year. Out of a known species total of over 2 million. That gives an annual percentage loss of less than 0.0001%. That's background extinction. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs. Of course, extinction is a natural part of the evolution of life on this planet with the average lifespan of a species thought to be about 1 million years (cf 930,000). It is estimated that 99.9% of all plant and animal species that have existed have gone extinct. It should also be noted that no families or genera have become extinct in the last 500 years. In fact marine diversity at the taxonomic level of families is the highest it has ever been in the Earth's long history (see Sepkoski Curve).
I would i agree that the future for mankind would look dark, if it wasnt for one small detail... Technology. We could end this socalled crises tomorrow if we just wanted to, with solar reflection. It has been proven safe and effectively since we have already done it unintentionally since the industrial revolution, and nothing major bad has happen, and a control version of that would be more safe. But for some reason we dont do it.
@@heww3960your magic friend, technology, won't save us.
were almost there
After 200,000 years of thriving, all ends in just 1 generation.
At the peak of our intellectual prowess and for the most shallow and stupid of reasons…
The rich don't care in their bunkers
Does anyone besides me see this as a world similar to that of Mad max: Fury Road?
Incorporated is the dystopia to go for. Most of it already has become real.
It won’t even be half as hospitable. Thunder road for a decade or so maybe. But only as a last gasp of humanity.
Methane is 155 times worse than CO2 not 20. That is according to AMEG (Arctic Methane Emergency Group) that made a presentation at the Paris Talks in 2016.
I agree, but the residence time in the atmosphere for methane is decades not millenia, so over the longterm it's impact needs to be reduced.
It's also a minor issue that could detract from the message being conveyed.
Anything over 5 degrees will just kill us all. It may take longer the closer it is to 5 degrees above it, but it’ll happen
Whats the lower explosive limit of methane? 5% The air would have to be 5% methane for a spark to make an explosion. Right?
It was warmer when the dinos lived but they died by the meteor that hit the earth from a long time ago, so what will happen next to us humans.?
Communism
How knows?
@@sauron9883 let's hope
Were definitly going towards 3 degrees plus. But if methane escapes .. , well were fucked. Its a snowball effect we cant stop. Fireball effect?
There is something called sai, solar reflection. Technology will "save" us.
Funny how all this end time scenarios are imagined if we don't stop climate change on earth meanwhile we prepare to inhabit the way less inhabitable planet Mars
Why is that funny? Because things are so bad, we're willing to brave anything to not have all our eggs in one basket? That seems noble and sad, but not really funny.
As long as the wealthy have a way out, its all good. Who reallly will be able to afford to go to Mars? Only a select few will go to Mars while the 99% of us die on this planet. Mars would be like the ultimate luxury neighborhood, where they could truly be separate from us savages. We should frankly oppose Mars terraforming at this point. Our resources are far better spent saving the planet like carbon capture technology.
@@ce742 that's like if somebody predicted that only the wealthy will go to the new world while the rest of will die to starvation and sickness
Living on Mars, now that's a hoax.

2.5-3 without feedbacks…
2C is only possible with as-yet-uninvented carbon extraction technologies.
I started bawling as soon as I saw this video, all of this so about 1,000 people can get richer.
The thing is this video actually understates the problem
Rip we're all fucked.
Much has changed in the last 8 years, with renewed hopes of not triggering a global warming.
The big question is: can we reverse it when it is not reversible, with those few people left….
Probably not and Vegas sure isn’t giving odds on this one.
Came here for the positive vibes
Alligators we alright, mate.

WHEN....NOT IF

Why do many people who talk about climate change online say corporations are bad or that improving the economy is the problem. Economics are important and they should be the way we change climate change. People who are aware of social problems I hope will engage in building business ideas to prevent these issues. That is how change happens in the world in a peaceful way.

This is like Transcendant from Xeelee

Venus on Earth.
Who thinks this is terrible but it would also be pretty cool to see
I would prefer a large asteroid impact to remove the blight of humanity but a quick death from climate change is always a great topper.
how much time for 5 degree from this time at such a pace?
For those who have brains to think, let them think.
I think the flying saucers and aliens came from Venus. Just too shy to show up.
Underground cities and hydroponics might save humanity.
Only problem is that WE are the ones making this problem. If we run away from the destruction we made, we will only repeat the same mistakes elsewhere until we run out of places to run. This begs the question: does humanity even deserve to continue. I sound bleak but I genuinely hate that we ruin all the other biodiversity that I feel that we have no right to continue.

Yea I can see this happening in the next 30-50years if we don't find a way to resolve these issues and lower earths temperature somehow.. We need to learn how to control our Earths Climate and Weather.
Not possible given the BEV, PV and Wind revolution.
How much time do we have now?
How did sulfur dioxide suddenly come into the picture?
When the planet warms, the poles heat up at a much faster rate, thus making the temperature differential between the Arctic and equator less extreme, which slows down the jet stream and ocean currents, which enables bacteria which thrive in this anoxic conditions to proliferate, and these bacteria emit hydrogen sulfide as a byproduct of their consumption.
@@lowkeylikeLoki I suspect that the only life to survive this mass extinction event will be anaerobic lifeforms and possibly very deep-sea life (near thermal vents and so on). If we don't go full 'Venus', evolution will start again and in, oh say a few hundred million years, there might be another species of stupid sentient beings to screw it all up for the planet. We are but a blip in an infinity of space-time.
Did I just see Superman fly by?
Golly gee!!!
What I guess we can glean from this is don't piss off the ocean, it will release its meeethane farts thus destroying the earth.
still sooner than half life 3

How did H2S and SO2 get into the picture? It was only CO2 and CH4 before.
*Methane is actually 100 times more potent in the first ten years of its life.....
Let's do math...calculation by using Ideal Gas Law.
No effect what so ever...
Welp everyone get the nooses and lets hang around for a few more minutes
The world is trying its best to keep our climate stable.
Polar vortex - That's the band of cool artic/antartic air that should be circulating the both poles.
Now it is migrating from the poles and cooling latitudes that should be warmer in the winter.
Hence the record snow and ice in north east America.
Melting ice caps - Cooler ocean currents are migrating away from the poles and keeping the thermahaline currents flowing.
ie the Gulf stream. The differing temperatures in the ocean between opposing latitudes.
Stagnation of these currents will lead to a rise in sea life death and destruction.
Tree growth - With the rise of CO2 in the atmosphere the earth would protect itself by growing millions of extra trees.
However, mankind is destroying these forests and once again releasing vast quantities of CO2.
Australia just recorded its hottest temperatures since records began.
North East America is suffering under record snowfall.
Mankind really has to allow the earth to heal itself.
It will in the Future.
By that time the earth's cancer may well be extinct.
I honestly came to this video after my science homework to learn a bit more.
I can't say I agree more with your statements.
