Yeah. Thankfully the scientist does. Conservation of angular momentum is fairly basic freshman year physics, just on a scale where we didn't expect to see a large enough change to cause a tangible result.
being a news anchor is one of the more talentless positions you can get on TV. Say what you want about the Fox talking heads but they have a talent for spinning bullshit. CNN's anchors talent (not all of them, some are good. Katelynn Collins actually seemed to level up after being put in that position to interview Trump) seems to just be reading a teleprompter and asking their guests dumb questions with no personality.
"people that think the earth is flat." Surprisingly, around Fargo the earth is extremely flat. After a heavy rain water just sits around with no place to go and no reason to go there.
"The people that think anthropogenic climate isn’t happening are probably the same people that think the earth is flat." Maybe. Have you got any SCIENCE to back up your claim?
The world isn't ending..the planet 🌏 keeps living on its the species that becomes extinct..if every human being was to no longer exists..the sun will still rise other creatures will still thrive just without us ..
the world itself is not. the planet could care less about us humans or life on this planet. which is rather disheartening I admit. so it is entirely on us to solve the climate change crisis and soon!!
"The world is literally ending and people don’t even care." Some do, some don't. There's only a few billion years left. I'm not sure that worrying about it will accomplish much.

Saying you studied a specific subject and can repeat the talking points your specific professors taught you. It doesn't make you smarter or different from those who don't have one.
The fact that things need to be adjusted in this way, shows absolutely peoples collective actions effect the earth and feedback to us. While a second is minor, the scale of the our effect is massive to say the least. It's sad that even the mention of the reason, global warming, creates instant defensive deflections.
melting of the poles redistributing mass at the surface of the earth especially at the equator will affect angular momentum thusly reducing the earth's rate of rotation. see, I studied physics and engineering. recommend it for young intelligent people.
My question or comment is that CNN reports that the rotation of the earth will spead up and we will loose a second in the day's length. Isn't it the opposite that is the case? Ice on the poles melts, moves towards the equator, the speed will slow down and the day may become one second longer?
When they decided to remove 11 days from the calendar in the Middle Ages people genuinely believed they were being cheated of some of their life. I know it's only a second, but if you believe that your time of death has been pre-ordained as a time in the Gregorian calendar then you will also believe that your life will be shortened.
Time keeping relies on highly technological clocks, on them depends official time like UTC, which influences computers' time keeping, etc. When Earth moves differently from what the clocks register, *it does mess up with time.*
I loved Dr. Mann's explanation. Sadly, I still think Fredericka was still confused as she repeated the same thing about "losing a second of our lives" even after Dr. Mann's clarification. I don't think she understands how arbitrary time is and how our practical measurement of it on Earth is based on our solar revolution.
We are “Not” going to be able to mitigate the global warming issue until we end all these useless wars and learn to get along as human beings. Wars burn 🔥 and are more destructive than anything else man has placed on this earth. Let there be peace! 😊
Um, if you redistribute weight from the poles (melting ice caps) to the equator (bulging oceans), wouldn't that make the rotation of the Earth slow down (like the skater extending her arms), requiring that time be ADDED to the day?
Human's like to think they make a change but reality is we don't live long enough plus the universe and our own planet considered us to be only an irritation
Mr scientist, if the ice is melting then as per principles of physics the overall volume of water should go down because the density of ice is lower than water.
Incorrect. The issue is that the ice that of concern is on land (eg Greenland, Antarctica) which will move from the land to the oceans and will only add to the volume of the oceans. The models of the sea level rise include the changes of water-borne ice.
There is a chance of a minute change of spin speed because of it. There may also be a tiny adjustment to the orbital path around the sun too. The change of speed by mass distribution will be much more significant.
The problem with the climate change debate is everyone is entrenched in partisan politics rather than accepting the fact both parties are right...the climate has always changed,its been melting since last ice age, volcanos, and we'll be fine if the caps melted its far better to have a warm planet than a cold one, taxing someone and reinventing your entire economy when other countries refuse to change isnt gonna fix anything...but you cant pump that much carbon into the atmosphere and expect to have no effect thats just asinine, you should strive to have less impact on your environment and try to live in harmony with it, were over populated its not a space thing its a resources/waste thing, if we were any other species wed be hunting us to curb the population we have nothing that keeps us in check, you cant expect to keep fucking like rabbits and expect no consequences youre an organism in an ecosystem...you can have gasoline cars etc u just cant have as many people....even water vapour is a green house gas...battery production is bad for environment also manufacturing of alot of these green technologies requires old tech/energy to produce...it doesnt matter what you do theres going to be some impact even dams and wind farms have their cons...there is no perfect thing...if were talking about here and now why arent we using nuclear? High speed electric trains instead of planes? Painting roads white and or having solar roads? Tidal power? What about a national funded programs to have tiny wind/solar technology on your house were applicable to take some strain off the grid and u get a rebate on taxes or u can sell it back to the grid whatever....i mean thers lots of things you can do...im pretty sure were all on board with not throwing trash out the window and dumping chemicals in rivers...if only everyone would just stfu and actually tried to solve the problem instead of claiming anyone with a different opinion is a threat to democracy and the bringer of the apocalypse
@@pereldh5741 "The end isnt even close even if we go 5deg up! Listen to the scientist." What? I assume that when you write "5deg" then you mean 5 degrees. The scientist did not talk about degrees but talked about seconds. 5 °F would have huge impact and would cause millions of people to die due to extreme weather, famine and most likely violent conflicts. But let me also be clear. The world is not going to end. Human wont be extinct any time soon(100+ years) due to climate change.
The only way to actually slow Earth's rotation is due to how the earth and moon system's angular momentum reaches a state of equilibrium which will increase the distance between the two. If I recall correctly, I think after 2 million years we will go from a 24 hour day to a 25 hour day.
The earth has been changing since time itself. We, as humans, noticed it even more today. Only because of our science is getting better every day . Yes , we are part of this change. Because what we put into the air , rivers and oceans. We can either help change our climate for the best or for the worst. The earth will continue to change it just up to us, which way it goes.
“All change is a miracle to contemplate; but it is a miracle which is taking place every instant” -Thoreau, Walden Knowing the climate history of our planet, I'm 0% worried about human induced climate change. I'm 100% worried about overpopulation and environmental destruction though. The Human Induced Mass Extinction Event we're causing as you ponder a few inconsequential degrees of temperature change...
I am not an expert at all but this is how I understand it. When the ice melts then the spinning of Earth goes faster because "the arms are retracted". When Earth spins faster then a full rotation will take less time and therefore time is subtracted. Again, I am no expert and I might be wrong.
@@franklin9400 I'm a physics grad, and I can speak with authority on this (not that much authority is needed, it's first year kinematics you can find in any intro textbook). @hanshansen3885 is correct. Angular momentum is a conserved quantity, equal to the moment of inertia times angular velocity. The moment of inertia is an integration of how far each individual piece of mass lies from the axis of rotation, and when that decreases -- say, an ice cap above sea level melts down -- the angular velocity increases proportionally. This is the mechanism of how an ice skater spins faster by tucking their arms in, and that is indeed the typical example first-years are shown to illustrate conservation of angular momentum. And in this particular case, such a large quantity of the earth's mass melted down a higher to a lower altitude that the planet spun a whole second faster.
@@Berahlen However what we are experiencing is that the water is moving from the polar region to the equator which is the equivalent of the ice skater holding their arms and leg out. This slows the spin.

IN THE INTEREST OF FINDING THE THEORY OF EVERYTHING: SOME THINGS MODERN SCIENCE DOES NOT APPARENTLY KNOW: Consider the following: a. Numbers: Modern science does not even know how numbers and certain mathematical constants exist for math to do what math does. Surely the very nature of reality has to allow numbers and mathematical constants to actually exist for math to do what math does in this existence. (And nobody as of yet has been able to show me how numbers and certain mathematical constants can come from the Standard Model Of Particle Physics). b. Space: Modern science does not even know what 'space' actually is nor how it could actually warp and expand. c. Time: Modern science does not even know what 'time' actually is nor how it could actually warp and vary. d. Gravity: Modern science does not even know what 'gravity' actually is nor how gravity actually does what it appears to do. And for those who claim that 'gravity' is matter warping the fabric of spacetime, see 'b' and 'c' above. e. Speed of Light: 'Speed', distance divided by time, distance being two points in space with space between those two points. But yet, here again, modern science does not even know what space and time actually are that makes up 'speed' and they also claim that space can warp and expand and time can warp and vary, so how could they truly know even what the speed of light actually is that they utilize in many of the formulas? Speed of light should also warp, expand and vary depending upon what space and time it was in. And if the speed of light can warp, expand and vary in space and time, how then do far away astronomical observations actually work that are based upon light and the speed of light that could warp, expand and vary in actual reality? f. Photons: A photon swirls with the 'e' and 'm' energy fields 90 degrees to each other. A photon is also considered massless. What keeps the 'e' and 'm' energy fields together across the vast universe for billions of light years? And why doesn't the momentum of the 'e' and 'm' energy fields as they swirl about not fling them away from the central area of the photon? And why aren't photons that go across the vast universe torn apart by other photons, including photons with the exact same energy frequency, and/or by matter, matter being made up of quarks, electrons and interacting energy, quarks and electrons being considered charged particles, each with their respective magnetic field with them? Electricity is electricity and magnetism is magnetism varying possibly only in energy modality, energy density and energy frequency. So why doesn't the 'e' and 'm' of other photons and of matter basically tear apart a photon going across the vast universe? Also, 'if' a photon actually red shifts, where does the red shifted energy go and why does the photon red shift? And for those who claim space expanding causes a photon to red shift, see 'b' above. Why does radio 'em' (large 'em' waves) have low energy and gamma 'em' (small 'em' waves) have high energy? And for those who say E = hf; see also 'b' and 'c' above. (f = frequency, cycles per second. But modern science claims space can warp and expand and time can warp and vary. If 'space' warps and expands and/or 'time' warps and varies, what does that do to 'E'? And why doesn't 'E' keep space from expanding and time from varying?). g. Energy: Modern science claims that energy cannot be created nor destroyed, it's one of the foundations of physics. Hence, energy is either truly a finite amount and eternally existent, or modern science is wrong. First Law Of Thermodynamics: "Energy can neither be created nor destroyed." How exactly is 'energy' eternally existent? h. Existence and Non-Existence side by side throughout all of eternity. How? * ADDED NOTE: My current TOE idea can potentially answer all of these above items, and more, in a logical, coherent and inter-related manner. And wouldn't one expect the true TOE of existence itself to be able to do that? What other TOE idea in known existence can currently do that? Surely not the General or Special Relativity Models nor even the Standard Model of Particle Physics. TOE Idea: Short version: (currently dependent upon the results of my gravity test): The 'gem' photon is the eternally existent energy unit of this universe. The strong and weak nuclear forces are derivatives of the electromagnetic ('em') interactions between quarks and electrons. The nucleus is a magnetic field boundary. 'Gravity' is a part of electromagnetic radiation, gravity acting 90 degrees to the 'em' modalities, which of course act 90 degrees to each other. 'Gravity' is not matter warping the fabric of spacetime, 'gravity' is a part of spacetime that helps to make up matter. The gravity and 'em' modalities of matter interact with the gravity and 'em' modalities of spacetime and the gravity and 'em' modalities of spacetime interact with the gravity and 'em' modalities of matter. I am open to any and all theory of everything ideas that can potentially answer all those above items in a logical, coherent and inter-related manner. Currently, as far as I am currently aware of, there are no others but my own.
The length of the day always gets changed and gets longer when winter passes and summer arrives day by day. What do they really mean by"Length of day changes" He didn't explain the concept of negative leap second, someone help me with this?
There is an existing slowing of the spin of the Earth due to the moon's orbit increasing (the moon is moving away from the earth at several cms a year). The video uses the example of an ice skater which show the difference of speed when the mass of the spinning body changes. As you move mass toward the axis center (skater's arms and legs held close) the spin speed increases, and as your move mass outward away from the axis (skater's arm and leg held out) then the spin speed decreases. There are many videos that explain this concept simply; search for conservation of angular momentum and ice skater.
@@trevx3680 Thanks! Help me with understanding that if the spin speed decreases, how do we subtract a second from a minute cz if the rotation gets slower means a minute will take one extra second to complete, not to subtract a second. My mind is if rotation increases we will then have 59 seconds cz the time will move faster?
@@naeemjani9938 We are not subtracting a second from a minute. The earth's rotation is 86,400 seconds (24 hours). Every century or two they will select a year and on 1st of January they will designate that day to be 86,401 seconds long. After that the days will return to 86,400 seconds. This will have no effect on our perception of time, but it does have dramatic effects on technologies that require precise time measurements in particular communication (eg satellites, and internet traffic).
"we also have unbalanced earth by moving all the materials here and there" I suppose there's a possibility of the earth falling over now that it is unbalanced.

Persistent westerly winds have also dragged the current in one direction for over 20 years, increasing the speed and size of the clockwise current and preventing the fresh water from leaving the Arctic Ocean. This decades-long western wind is unusual for the region, where previously, the winds changed direction every five to seven year. Scientists have been keeping an eye on the Beaufort Gyre in case the wind changes direction again. If the direction were to change, the wind would reverse the current, pulling it counterclockwise and releasing the water it has accumulated all at once. "If the Beaufort Gyre were to release the excess fresh water into the Atlantic Ocean, it could potentially slow down its circulation. And that would have hemisphere-wide implications for the climate, especially in Western Europe," said Tom Armitage, lead author of the study and polar scientist at NASA's Jet Propulsion Laboratory in Pasadena, California. Fresh water released from the Arctic Ocean to the North Atlantic can change the density of surface waters. Normally, water from the Arctic loses heat and moisture to the atmosphere and sinks to the bottom of the ocean, where it drives water from the north Atlantic Ocean down to the tropics like a conveyor belt. This important current is called the Atlantic Meridional Overturning Circulation and helps regulate the planet's climate by carrying heat from the tropically-warmed water to northern latitudes like Europe and North America. If slowed enough, it could negatively impact marine life and the communities that depend on it. "We don't expect a shutting down of the Gulf Stream, but we do expect impacts. That's why we're monitoring the Beaufort Gyre so closely," said Alek Petty, a co-author on the paper and polar scientist at NASA's Goddard Space Flight Center in Greenbelt, Maryland. The study also found that, the Beaufort Gyre is out of balance because of the added energy from the wind, the current expels that excess energy by forming small, circular eddies of water. While the increased turbulence has helped keep the system balanced, it has the potential to lead to further ice melt because it mixes layers of cold, fresh water with relatively warm, salt water below. The melting ice could, in turn, lead to changes in how nutrients and organic material in the ocean are mixed, significantly affecting the food chain and wildlife in the Arctic. The results reveal a delicate balance between wind and ocean as the sea ice pack recedes under climate change. "What this study is showing is that the loss of sea ice has really important impacts on our climate system that we're only just discovering," said Petty.

About the same as a gas vehicle - so what? Once produced they have a zero CO2 footprint. And, BTW, as we transition to green energy that production footprint goes down too! You do not seem very bright to me.
@@pdoylemi Correct, gas cars had a smaller but similar-ish footprint. What you’re pretending to forget is that we have a global boom, a ”transition” which never would’ve occurred otherwise. We’d still be driving our 2012 car, or maybe buy a 2nd hand when the time comes. We even have tax incentives for buying new EV’s. A consuming boom. Already the market is flooded, not only because a 5year old EV’s already outdated so we’ll buy a new one again. To add to that, the charging network bulid-up GLOBALLY pollutes nearly as much CO2, and we’ve only started (clearly…) Of course in the long run, with better battery tech than today, EV’s will have a natural place, but the panic angst-driven rush we at least have here in Scandinavia is in the short-term contraproductive to stop climate change. And no, EV’s never have a zero usage footprint, unless you charge it 100% from your own windmill.. (still that has to be made too..) China & Germany have 75% fossile electricity for example. And thats not changing anytime soon. And then we have the extremely complicated, dirty & energy consuming EV recycling problem.. Oh I could go on.. What we should do is stop consuming in this massive fashion. Change fuel from fossile to non-fossile, use existing charging(pump) networks. Thats the clever way.
The initial CO2 emissions of manufacturing EVs are greater than regular vehicles but their CO2 emissions during use is extremely low compared to regular vehicles, so it only take a couple of years until it breaks even. After that then EVs have much less CO2 emissions. Btw I think you are a bit high on the CO2 production footprint. It really depends on where the materials come from and where the components are made. There is roughly a difference of 5-10 tonne CO2 emissions between a gasoline/diesel vehicle and an EV, depending on the size. Those CO2 emissions are quickly saved by the EV in use.
@@hanshansen3885 No those numbers are official Volvo numbers for their small SUV EX30 and XC40 EV. However you too are missing the point. We are buying new cars en masse toady, period.

What about all the magma moving beneath the earths crust , and then released from an eruption?? Or shifts in tectonic plates , do the affect the rotation of the earth. Maybe play with the magnetic poles ?? Climate seems it can be effected by many different and complex earth occurrences. Yes , No ??
And after taking all that into account you realize that there are still significant climate differences? These differences are mostly accounted by including human pollution (particularly carbon and methane) and human destruction of environmental regions.
@@trevx3680 did you for get cattle and their methane discharge. Probably more methane from them than CO2 from all other sources. My fear right now is nuclear not climate and it's changes. We know there have been other episodes of ice , heat , cooling , warming through millions of years. The planet will decided when to cleanse itself , no matter what we do.
@@thesink5723 The models account for cattle emissions. There is research into diet changes to lower their emissions. The issue is not that the planet will change from ice age to warmer periods, it is the rate of change. It is also the destruction and change of our ecosystems that help keep our climate stable. This means that catastrophic changes in our climate are likely on the scale of hundreds of years instead of thousands of years.
Did they drop you out of a window on the 3rd floor of your high school bro? High school grade 10 graduate here that knows the 'moon' has been doing that feat since before any ice first formed on this planet dude.
The moon slows earth's rotation by about 2 milliseconds every 100 years. The sheer amount of sea ice that's melted in the last century sped up the earth's rotation by orders of magnitude more.
Is the earth supposed to stay in its original shape? I thought it was constantly changing! Wow, guess it’s time to take out my 3rd grade science book. Lol
It's one second per year. Not a second per day. It has nothing to do with more or less time. We just require all clocks to be on the same markings. For our satellites to operate properly.
@@carsonwhitney4100 The Earth does change naturally without human intervention, but it also changes due to human intervention. We managed to save the ozone hole by reversing some of our harmful effects.
I am all for planting more trees but I think it would be better just to stop cutting so many down all the time because we need new lawn chairs or a new dinner table. Consume less and reuse materials if possible. Just a quick note. *Every second* of the year there are 400 trees cut down around the world that isnt replaced by new(planted) trees.
The Earth's naturally occurring processes have always caused the slightest fluctuations in the actual time within a 'man-made' day if it is something caused by the Earth's natural processes. Humans made daylight savings time, which alters the perception of time. We just had leap year day too, indicating that time doesn't follow the man-made calendar. The climate of the planet has varied in the planets history: the ice age consisting of the past 2.6 Million years has had multiple glacial (cold) and interglacial (warm) times. We are in an interglacial time, would people really prefer to go back to a glacial period? The climate is going to do what the climate is going to do!
We are well outside "slight fluctuations" we are into an exponential increase in global temperature. Your position may have been valid in the 1960s but each decade since shows how well outside any natural processes we are experiencing. The same happened with the ozone layer. For decades before the 1980s we increased our CFCs which caused a breakdown in ozone. Since the near ban (China has been breaking it recently) in the 1980s it is recovering. This process is very well studied and understood and caused a global change that would have increased cancer for every living surface creature.
@@trevx3680 This video is talking about losing one second of time supposedly for the first time in Earth's history because of naturally occurring events, but scientists don't know when it will happen. Is one second of time really that significant? The Earth has gone through multiple glacial (cold) and interglacial (warm) times during the ice age (consisting of the past 2.6 million years). The temperatures have fluctuated during this interglacial time including somewhat cooler times like 535-536 AD due to a large volcanic eruption, 1815-1816 known as "The year without a summer" due to the eruption of Tambora, and the time known as "The little ice age" (from ~1300-1850) as well as warmer times during this interglacial period. We are not outside any normal process. It is well understood that as the Earth warms it melts the ice; and it is well known that ice reflects the sunlight and as more land exposed (because of the ice melting) it will absorb heat and creates a warming process. Add in all of the roads and buildings that humans have made and absorb more heat, the Earth would be expected to getting warmer. Humans may play a part, but there are natural processes that contribute to the climate as well. According to scientists, the mass extinction ~250 million years ago was caused by a volcanic eruption lasting about a million years that wiped out the ozone. It obviously can recover. If CFC's in a specific place are the cause of the ozone problem, how is it that Antarctica and places over the ocean have problems? How is it that the US even has any ozone anymore if that's the case?
@@wildwolfwind6557 Wow. One second is significant. It shows the scale of the problem over the last century. If we had not been affecting the planet then this would not even be measurable. It is yet another significant measurement of how humans are dramatically affecting the planet's geosystems and ecosystem. While you are correct in that significant changes in climate have happened before, when the abrupt and exponential changes we are experiencing now happened in the past it led to a global extinction event. Regarding ozone, the ozone is in the most upper part of the atmosphere and the currents that take it up there are at the poles, and in particular the south pole. There is a great deal of information about this if you want to know. I urge you do that before making further uninformed opinions.
@@trevx3680 I also thought I'd mention that about a year ago, there was quite a bit of news about the inner core slowing down and some said "the inner core slowing down and now about to reverse direction". Another about the inner core slowing said it could lengthen the days. A different article says "Researchers believe the inner core's rotational speed oscillates a bit like a pendulum, slowing down and speeding up over a 70-year cycle." Others think that the core slowing might have been an indication of a pole reversal. Plus, from Mar 12, 2021 an article saying "For billions of years, the moon has been ever so gently tugging at the Earth and slowing down its rotation. The moon's gravity is the reason ..." And, from Nov 27, 2010 - "The earth's rotation is slowing down, due primarily to tidal interaction with the moon (transferring angular momentum to the moon)". Obviously not all scientists agree on these things.
@@wildwolfwind6557 You have misinterpreted the science. Pole reversal has nothing to do with the rotation of the earth. Changes in the inner core are beyond our ability to predict with any accuracy, however its current state is measurable. The moon's slow drift away from the Earth is well known and easily measurable. The physics of mass distribution from the center axis to the outer axis is well known and WILL always slow down the body. You have attempted to say there is significant doubt about the science when that is completely untrue. You have also completely missed the point. Humans are affecting the geosystems and ecosystems of the planet. This is indisputable.

If its such an issue, why do we stop ourselves from producing energy and materials in the safest, cleanest ways, and instead buy them from nations that dont give 2 sh**s about it? And the EV situation doesn't help, look into the mining and extraction processes. After those batteries are made, then you still have to charge them, again... how? More batteries on a solar system with more resources used to make the panels? So expensive that they never pay themselves off? You really think the places we buy our resources from will ever change? No. We dont use hydro energy properly at all either. In a single homemade waste gate, I can chain 10 100 amp alternators from a 200 gallon a minute flow tube and produce enough energy to run my own home. They dont want you using such a clean method, because it steals profits. Yet, like with the pipeline, these issues dont seem to matter much to those in charge, its just a way to generate wealth. Nordstrom alone was the most destructive situation ever seen ecologically speaking. We dont whine about the bombs, materials used for endless war, do we? Even if full global control ever happened, the people would pay the price, even still for the luxuries of the 1 percent who got to use whatever they wanted. Thats the scam, not climate change, but the fact those pushing the agenda are the ones causing it, and profiting every step as you get more broke.
"why do we stop ourselves from producing energy and materials in the safest, cleanest ways" From the rest of your comment I can assume that you are talking about LNG and not renewable energy. LNG is cleaner than oil and coal but it is still far dirtier than renewable energy and nuclear energy. "And the EV situation doesn't help, look into the mining and extraction processes." You focus on one thing and dont see the entire picture. EVs are much cleaner(less CO2 emissions) than gasoline/diesel vehicles during their entire "life cycle". "After those batteries are made, then you still have to charge them, again... how?" Renewable energy, very simple. "So expensive that they never pay themselves off?" I really dont know where you get that from but that is only if you get scammed by the seller. "You really think the places we buy our resources from will ever change?" The rest of the world is changing faster than America. "We dont use hydro energy properly at all either." Some people do if they have that option but not all. "In a single homemade waste gate, I can chain 10 100 amp alternators from a 200 gallon a minute flow tube and produce enough energy to run my own home." It is awesome that you are able to do that but most people do not have access to that water flow. "Nordstrom alone was the most destructive situation ever seen ecologically speaking."

Wait, if I did physics correctly, L = r X p, which means it's dependent on mass, but ice melting into water is still the same mass, so how does it slow Earth by that much??
Because the mass isn't sitting at the same radius anymore. In this case, L = Iω is more useful. When sea ice melts from a taller landmass down to sea level, the moment of inertia I reduces (remember, that's an integral of mass distribution relative to the radius at each integrated element), causing the angular velocity ω to increase proportionally. The guy in the video compares it to an ice skater tucking their arms in to spin faster despite no external force, because their mass moves closer to the center of rotation.
There was a time when there we no ice caps on the earth and all living creatures tens upon tens of millions of years ago still managed to adapt..a second more a second less makes no difference at all ..remember your concept of time when you were ten yrs old ..I don't. never worried about it until the internet came along...
do your own research. the issue is the melting is occurring at a rate unprecedented since possibly the great meteor impact that caused the extinction of the dinosaurs. entirely by man's emitting tons upon tons of CO2 each day over the last 100 yrs especially.

Yours is an example. Here they are!
The fact that things need to be adjusted in this way, shows absolutely peoples collective actions effect the earth and feedback to us. While a second is minor, the scale of the our effect is massive to say the least. It's sad that even the mention of the reason, global warming, creates instant defensive deflections.
very intelligent poisoning the atmosphere with warming gases and burning the oxygen we breathe at the same time. That among other things😢
melting of the poles redistributing mass at the surface of the earth especially at the equator will affect angular momentum thusly reducing the earth's rate of rotation. see, I studied physics and engineering. recommend it for young intelligent people.
My question or comment is that CNN reports that the rotation of the earth will spead up and we will loose a second in the day's length. Isn't it the opposite that is the case? Ice on the poles melts, moves towards the equator, the speed will slow down and the day may become one second longer?
i love how the news anchor is like mmm yeah i know what your talking about but in reality they have no idea what this man is saying 😂
This does not “mess with time”, change the length of the day, or give people fewer seconds in their lives. Other than that, good reporting.
It doesn't subtract time from your life. 😂
When they decided to remove 11 days from the calendar in the Middle Ages people genuinely believed they were being cheated of some of their life. I know it's only a second, but if you believe that your time of death has been pre-ordained as a time in the Gregorian calendar then you will also believe that your life will be shortened.
actually it does decrease the day length by a second.
Time keeping relies on highly technological clocks, on them depends official time like UTC, which influences computers' time keeping, etc. When Earth moves differently from what the clocks register, *it does mess up with time.*
dam I only get to clock out 1 sec early. I take longer to clock out
I loved Dr. Mann's explanation. Sadly, I still think Fredericka was still confused as she repeated the same thing about "losing a second of our lives" even after Dr. Mann's clarification. I don't think she understands how arbitrary time is and how our practical measurement of it on Earth is based on our solar revolution.
We are “Not” going to be able to mitigate the global warming issue until we end all these useless wars and learn to get along as human beings. Wars burn 🔥 and are more destructive than anything else man has placed on this earth. Let there be peace! 😊

Um, if you redistribute weight from the poles (melting ice caps) to the equator (bulging oceans), wouldn't that make the rotation of the Earth slow down (like the skater extending her arms), requiring that time be ADDED to the day?

Mr scientist, if the ice is melting then as per principles of physics the overall volume of water should go down because the density of ice is lower than water.
Incorrect. The issue is that the ice that of concern is on land (eg Greenland, Antarctica) which will move from the land to the oceans and will only add to the volume of the oceans. The models of the sea level rise include the changes of water-borne ice.

You big showoff.
I understand that the eruption of Hunga Tonga in January 2021 actually changed our tilt slightly. Did it also affect the speed of our rotation?
Naah but it probably shunted the planet slightly closer to the moon or slightly further away from it. lol
Who knows.
There is a chance of a minute change of spin speed because of it. There may also be a tiny adjustment to the orbital path around the sun too. The change of speed by mass distribution will be much more significant.
"Did it also affect the speed of our rotation?"
I don't know. How fast do you rotate? My rotation does seem a bit slower as I get older.

The problem with the climate change debate is everyone is entrenched in partisan politics rather than accepting the fact both parties are right...the climate has always changed,its been melting since last ice age, volcanos, and we'll be fine if the caps melted its far better to have a warm planet than a cold one, taxing someone and reinventing your entire economy when other countries refuse to change isnt gonna fix anything...but you cant pump that much carbon into the atmosphere and expect to have no effect thats just asinine, you should strive to have less impact on your environment and try to live in harmony with it, were over populated its not a space thing its a resources/waste thing, if we were any other species wed be hunting us to curb the population we have nothing that keeps us in check, you cant expect to keep fucking like rabbits and expect no consequences youre an organism in an ecosystem...you can have gasoline cars etc u just cant have as many people....even water vapour is a green house gas...battery production is bad for environment also manufacturing of alot of these green technologies requires old tech/energy to produce...it doesnt matter what you do theres going to be some impact even dams and wind farms have their cons...there is no perfect thing...if were talking about here and now why arent we using nuclear?

@@pereldh5741 I replied earlier but someone deleted the comment.

The only way to actually slow Earth's rotation is due to how the earth and moon system's angular momentum reaches a state of equilibrium which will increase the distance between the two. If I recall correctly, I think after 2 million years we will go from a 24 hour day to a 25 hour day.
The earth has been changing since time itself. We, as humans, noticed it even more today. Only because of our science is getting better every day . Yes , we are part of this change. Because what we put into the air , rivers and oceans.
We can either help change our climate for the best or for the worst. The earth will continue to change it just up to us, which way it goes.

But shouldn't we be adding time if the polar ice is melting?
I am not an expert at all but this is how I understand it. When the ice melts then the spinning of Earth goes faster because "the arms are retracted". When Earth spins faster then a full rotation will take less time and therefore time is subtracted.
Again, I am no expert and I might be wrong.
@@hanshansen3885Just say you have no knowledge. 😂 All you did was try to parrot what you just heard. "The arms are retracted" 😂
@@franklin9400 I'm a physics grad, and I can speak with authority on this (not that much authority is needed, it's first year kinematics you can find in any intro textbook). @hanshansen3885 is correct. Angular momentum is a conserved quantity, equal to the moment of inertia times angular velocity. The moment of inertia is an integration of how far each individual piece of mass lies from the axis of rotation, and when that decreases -- say, an ice cap above sea level melts down -- the angular velocity increases proportionally. This is the mechanism of how an ice skater spins faster by tucking their arms in, and that is indeed the typical example first-years are shown to illustrate conservation of angular momentum. And in this particular case, such a large quantity of the earth's mass melted down a higher to a lower altitude that the planet spun a whole second faster.
@@Berahlen However what we are experiencing is that the water is moving from the polar region to the equator which is the equivalent of the ice skater holding their arms and leg out. This slows the spin.

Matthew 24:22
IN THE INTEREST OF FINDING THE THEORY OF EVERYTHING:
SOME THINGS MODERN SCIENCE DOES NOT APPARENTLY KNOW:
Consider the following:
a. Numbers: Modern science does not even know how numbers and certain mathematical constants exist for math to do what math does. Surely the very nature of reality has to allow numbers and mathematical constants to actually exist for math to do what math does in this existence. (And nobody as of yet has been able to show me how numbers and certain mathematical constants can come from the Standard Model Of Particle Physics).
b. Space: Modern science does not even know what 'space' actually is nor how it could actually warp and expand.
c. Time: Modern science does not even know what 'time' actually is nor how it could actually warp and vary.
d. Gravity: Modern science does not even know what 'gravity' actually is nor how gravity actually does what it appears to do. And for those who claim that 'gravity' is matter warping the fabric of spacetime, see 'b' and 'c' above.
e. Speed of Light: 'Speed', distance divided by time, distance being two points in space with space between those two points. But yet, here again, modern science does not even know what space and time actually are that makes up 'speed' and they also claim that space can warp and expand and time can warp and vary, so how could they truly know even what the speed of light actually is that they utilize in many of the formulas? Speed of light should also warp, expand and vary depending upon what space and time it was in. And if the speed of light can warp, expand and vary in space and time, how then do far away astronomical observations actually work that are based upon light and the speed of light that could warp, expand and vary in actual reality?
f. Photons: A photon swirls with the 'e' and 'm' energy fields 90 degrees to each other. A photon is also considered massless. What keeps the 'e' and 'm' energy fields together across the vast universe for billions of light years? And why doesn't the momentum of the 'e' and 'm' energy fields as they swirl about not fling them away from the central area of the photon? And why aren't photons that go across the vast universe torn apart by other photons, including photons with the exact same energy frequency, and/or by matter, matter being made up of quarks, electrons and interacting energy, quarks and electrons being considered charged particles, each with their respective magnetic field with them?
Electricity is electricity and magnetism is magnetism varying possibly only in energy modality, energy density and energy frequency. So why doesn't the 'e' and 'm' of other photons and of matter basically tear apart a photon going across the vast universe?
Also, 'if' a photon actually red shifts, where does the red shifted energy go and why does the photon red shift? And for those who claim space expanding causes a photon to red shift, see 'b' above.
Why does radio 'em' (large 'em' waves) have low energy and gamma 'em' (small 'em' waves) have high energy? And for those who say E = hf; see also 'b' and 'c' above. (f = frequency, cycles per second. But modern science claims space can warp and expand and time can warp and vary. If 'space' warps and expands and/or 'time' warps and varies, what does that do to 'E'? And why doesn't 'E' keep space from expanding and time from varying?).
g. Energy: Modern science claims that energy cannot be created nor destroyed, it's one of the foundations of physics. Hence, energy is either truly a finite amount and eternally existent, or modern science is wrong. First Law Of Thermodynamics: "Energy can neither be created nor destroyed." How exactly is 'energy' eternally existent?
h. Existence and Non-Existence side by side throughout all of eternity. How?
* ADDED NOTE: My current TOE idea can potentially answer all of these above items, and more, in a logical, coherent and inter-related manner. And wouldn't one expect the true TOE of existence itself to be able to do that? What other TOE idea in known existence can currently do that? Surely not the General or Special Relativity Models nor even the Standard Model of Particle Physics.
TOE Idea: Short version: (currently dependent upon the results of my gravity test):
The 'gem' photon is the eternally existent energy unit of this universe.
The strong and weak nuclear forces are derivatives of the electromagnetic ('em') interactions between quarks and electrons. The nucleus is a magnetic field boundary. 'Gravity' is a part of electromagnetic radiation, gravity acting 90 degrees to the 'em' modalities, which of course act 90 degrees to each other. 'Gravity' is not matter warping the fabric of spacetime, 'gravity' is a part of spacetime that helps to make up matter. The gravity and 'em' modalities of matter interact with the gravity and 'em' modalities of spacetime and the gravity and 'em' modalities of spacetime interact with the gravity and 'em' modalities of matter.
I am open to any and all theory of everything ideas that can potentially answer all those above items in a logical, coherent and inter-related manner. Currently, as far as I am currently aware of, there are no others but my own.

There is an existing slowing of the spin of the Earth due to the moon's orbit increasing (the moon is moving away from the earth at several cms a year).
The video uses the example of an ice skater which show the difference of speed when the mass of the spinning body changes. As you move mass toward the axis center (skater's arms and legs held close) the spin speed increases, and as your move mass outward away from the axis (skater's arm and leg held out) then the spin speed decreases. There are many videos that explain this concept simply; search for conservation of angular momentum and ice skater.
@@trevx3680 Thanks! Help me with understanding that if the spin speed decreases, how do we subtract a second from a minute cz if the rotation gets slower means a minute will take one extra second to complete, not to subtract a second. My mind is if rotation increases we will then have 59 seconds cz the time will move faster?
@@naeemjani9938 We are not subtracting a second from a minute. The earth's rotation is 86,400 seconds (24 hours). Every century or two they will select a year and on 1st of January they will designate that day to be 86,401 seconds long. After that the days will return to 86,400 seconds.

Persistent westerly winds have also dragged the current in one direction for over 20 years, increasing the speed and size of the clockwise current and preventing the fresh water from leaving the Arctic Ocean. This decades-long western wind is unusual for the region, where previously, the winds changed direction every five to seven year.
Scientists have been keeping an eye on the Beaufort Gyre in case the wind changes direction again. If the direction were to change, the wind would reverse the current, pulling it counterclockwise and releasing the water it has accumulated all at once.
"If the Beaufort Gyre were to release the excess fresh water into the Atlantic Ocean, it could potentially slow down its circulation. And that would have hemisphere-wide implications for the climate, especially in Western Europe," said Tom Armitage, lead author of the study and polar scientist at NASA's Jet Propulsion Laboratory in Pasadena, California.
Fresh water released from the Arctic Ocean to the North Atlantic can change the density of surface waters. Normally, water from the Arctic loses heat and moisture to the atmosphere and sinks to the bottom of the ocean, where it drives water from the north Atlantic Ocean down to the tropics like a conveyor belt.
This important current is called the Atlantic Meridional Overturning Circulation and helps regulate the planet's climate by carrying heat from the tropically-warmed water to northern latitudes like Europe and North America. If slowed enough, it could negatively impact marine life and the communities that depend on it.
"We don't expect a shutting down of the Gulf Stream, but we do expect impacts. That's why we're monitoring the Beaufort Gyre so closely," said Alek Petty, a co-author on the paper and polar scientist at NASA's Goddard Space Flight Center in Greenbelt, Maryland.
The study also found that, the Beaufort Gyre is out of balance because of the added energy from the wind, the current expels that excess energy by forming small, circular eddies of water. While the increased turbulence has helped keep the system balanced, it has the potential to lead to further ice melt because it mixes layers of cold, fresh water with relatively warm, salt water below. The melting ice could, in turn, lead to changes in how nutrients and organic material in the ocean are mixed, significantly affecting the food chain and wildlife in the Arctic. The results reveal a delicate balance between wind and ocean as the sea ice pack recedes under climate change.
"What this study is showing is that the loss of sea ice has really important impacts on our climate system that we're only just discovering," said Petty.

And now we’re rushing to buy billions of EV’s, 25-30tonne CO2 in production footprint… Each!
About the same as a gas vehicle - so what? Once produced they have a zero CO2 footprint. And, BTW, as we transition to green energy that production footprint goes down too! You do not seem very bright to me.
@@pdoylemi Correct, gas cars had a smaller but similar-ish footprint. What you’re pretending to forget is that we have a global boom, a ”transition” which never would’ve occurred otherwise. We’d still be driving our 2012 car, or maybe buy a 2nd hand when the time comes. We even have tax incentives for buying new EV’s.
A consuming boom. Already the market is flooded, not only because a 5year old EV’s already outdated so we’ll buy a new one again.
To add to that, the charging network bulid-up GLOBALLY pollutes nearly as much CO2, and we’ve only started (clearly…)
Of course in the long run, with better battery tech than today, EV’s will have a natural place, but the panic angst-driven rush we at least have here in Scandinavia is in the short-term contraproductive to stop climate change.
And no, EV’s never have a zero usage footprint, unless you charge it 100% from your own windmill.. (still that has to be made too..) China & Germany have 75% fossile electricity for example. And thats not changing anytime soon.
And then we have the extremely complicated, dirty & energy consuming EV recycling problem.. Oh I could go on..
What we should do is stop consuming in this massive fashion. Change fuel from fossile to non-fossile, use existing charging(pump) networks. Thats the clever way.
@@pdoylemiEV's are worthless and shouldn't be forced down our throats by the crazy environmentalist running the Whitehouse...
The initial CO2 emissions of manufacturing EVs are greater than regular vehicles but their CO2 emissions during use is extremely low compared to regular vehicles, so it only take a couple of years until it breaks even. After that then EVs have much less CO2 emissions.
Btw I think you are a bit high on the CO2 production footprint. It really depends on where the materials come from and where the components are made. There is roughly a difference of 5-10 tonne CO2 emissions between a gasoline/diesel vehicle and an EV, depending on the size. Those CO2 emissions are quickly saved by the EV in use.

@@trevx3680 did you for get cattle and their methane discharge. Probably more methane from them than CO2 from all other sources. My fear right now is nuclear not climate and it's changes.

@@thesink5723 The models account for cattle emissions. There is research into diet changes to lower their emissions.
The issue is not that the planet will change from ice age to warmer periods, it is the rate of change. It is also the destruction and change of our ecosystems that help keep our climate stable. This means that catastrophic changes in our climate are likely on the scale of hundreds of years instead of thousands of years.

The moon slows earth's rotation by about 2 milliseconds every 100 years. The sheer amount of sea ice that's melted in the last century sped up the earth's rotation by orders of magnitude more.
@@Berahlen What about all the ice that rapidly melted 12,000 years ago? That must have had a major effect too. Life found a way none the less.
@@FourTwenny Yes, you are correct. The planet's spin has never been constant. In fact, due to friction, every planet's spin is always changing.

It is ever changing. Where I live ise to be an ocean....its gonna keep changing..
melting ice doesnt effect the rotation lol
Six/6 minutes per year? Think of all you could do!
It's one second per year. Not a second per day. It has nothing to do with more or less time. We just require all clocks to be on the same markings. For our satellites to operate properly.
I guessed that this would happen exactly like it is...i imaged almost exactly what he was saying
I wonder what climate deniers would say about this..
You do realize the earth is constantly changing naturally without human intervention
@@carsonwhitney4100 The Earth does change naturally without human intervention, but it also changes due to human intervention. We managed to save the ozone hole by reversing some of our harmful effects.

I’d say nature’s own processes and dynamics contribute more to atmospheric conditions than any man-made activity. Fact.

That means more tree planting
I am all for planting more trees but I think it would be better just to stop cutting so many down all the time because we need new lawn chairs or a new dinner table. Consume less and reuse materials if possible.
Just a quick note. *Every second* of the year there are 400 trees cut down around the world that isnt replaced by new(planted) trees.
Hemp seeds would’ve faster to grow and provide more protein to eat.
The Earth's naturally occurring processes have always caused the slightest fluctuations in the actual time within a 'man-made' day if it is something caused by the Earth's natural processes. Humans made daylight savings time, which alters the perception of time. We just had leap year day too, indicating that time doesn't follow the man-made calendar. The climate of the planet has varied in the planets history: the ice age consisting of the past 2.6 Million years has had multiple glacial (cold) and interglacial (warm) times. We are in an interglacial time, would people really prefer to go back to a glacial period? The climate is going to do what the climate is going to do!
We are well outside "slight fluctuations" we are into an exponential increase in global temperature. Your position may have been valid in the 1960s but each decade since shows how well outside any natural processes we are experiencing.
The same happened with the ozone layer. For decades before the 1980s we increased our CFCs which caused a breakdown in ozone. Since the near ban (China has been breaking it recently) in the 1980s it is recovering. This process is very well studied and understood and caused a global change that would have increased cancer for every living surface creature.
@@trevx3680 This video is talking about losing one second of time supposedly for the first time in Earth's history because of naturally occurring events, but scientists don't know when it will happen. Is one second of time really that significant? The Earth has gone through multiple glacial (cold) and interglacial (warm) times during the ice age (consisting of the past 2.6 million years). The temperatures have fluctuated during this interglacial time including somewhat cooler times like 535-536 AD due to a large volcanic eruption, 1815-1816 known as "The year without a summer" due to the eruption of Tambora, and the time known as "The little ice age" (from ~1300-1850) as well as warmer times during this interglacial period.
We are not outside any normal process. It is well understood that as the Earth warms it melts the ice; and it is well known that ice reflects the sunlight and as more land exposed (because of the ice melting) it will absorb heat and creates a warming process. Add in all of the roads and buildings that humans have made and absorb more heat, the Earth would be expected to getting warmer. Humans may play a part, but there are natural processes that contribute to the climate as well.
According to scientists, the mass extinction ~250 million years ago was caused by a volcanic eruption lasting about a million years that wiped out the ozone. It obviously can recover. If CFC's in a specific place are the cause of the ozone problem, how is it that Antarctica and places over the ocean have problems? How is it that the US even has any ozone anymore if that's the case?
@@wildwolfwind6557 Wow. One second is significant. It shows the scale of the problem over the last century. If we had not been affecting the planet then this would not even be measurable. It is yet another significant measurement of how humans are dramatically affecting the planet's geosystems and ecosystem.
While you are correct in that significant changes in climate have happened before, when the abrupt and exponential changes we are experiencing now happened in the past it led to a global extinction event.
Regarding ozone, the ozone is in the most upper part of the atmosphere and the currents that take it up there are at the poles, and in particular the south pole. There is a great deal of information about this if you want to know. I urge you do that before making further uninformed opinions.
@@trevx3680 I also thought I'd mention that about a year ago, there was quite a bit of news about the inner core slowing down and some said "the inner core slowing down and now about to reverse direction". Another about the inner core slowing said it could lengthen the days. A different article says "Researchers believe the inner core's rotational speed oscillates a bit like a pendulum, slowing down and speeding up over a 70-year cycle." Others think that the core slowing might have been an indication of a pole reversal.
Plus, from Mar 12, 2021 an article saying "For billions of years, the moon has been ever so gently tugging at the Earth and slowing down its rotation. The moon's gravity is the reason ..." And, from Nov 27, 2010 - "The earth's rotation is slowing down, due primarily to tidal interaction with the moon (transferring angular momentum to the moon)". Obviously not all scientists agree on these things.
@@wildwolfwind6557 You have misinterpreted the science. Pole reversal has nothing to do with the rotation of the earth. Changes in the inner core are beyond our ability to predict with any accuracy, however its current state is measurable. The moon's slow drift away from the Earth is well known and easily measurable. The physics of mass distribution from the center axis to the outer axis is well known and WILL always slow down the body.
You have attempted to say there is significant doubt about the science when that is completely untrue. You have also completely missed the point. Humans are affecting the geosystems and ecosystems of the planet. This is indisputable.
OMG someone get this anchor a latte. Her commentary is inane, it's clear she's totally uniformed on the content of the segment, this is a small but fascinating piece of science to learn and think about. And then the framing of climate change - pitiful. It's the most significant issue of our time and she can't seem to think of a cogent conclusion for the conversation. This is one of the top 5 climate science researchers in the WORLD she's talking to...like would she talk to a president like this???
We will become dinosaurs again.
Longer days mean more melting 🤯
We won't see it in our life time it will take 22 to 24 thousand years for both northern and southern polar ice caps to melt completely at current fossil fuel consumption rate..
And adds to higher heat waves. 🤷
It is only our perception of time that would be " theoretically " affected. Stop lapping up this garbage really.

If its such an issue, why do we stop ourselves from producing energy and materials in the safest, cleanest ways, and instead buy them from nations that dont give 2 sh**s about it? And the EV situation doesn't help, look into the mining and extraction processes. After those batteries are made, then you still have to charge them, again... how? More batteries on a solar system with more resources used to make the panels? So expensive that they never pay themselves off? You really think the places we buy our resources from will ever change? No. We dont use hydro energy properly at all either. In a single homemade waste gate, I can chain 10 100 amp alternators from a 200 gallon a minute flow tube and produce enough energy to run my own home. They dont want you using such a clean method, because it steals profits. Yet, like with the pipeline, these issues dont seem to matter much to those in charge, its just a way to generate wealth. Nordstrom alone was the most destructive situation ever seen ecologically speaking. We dont whine about the bombs, materials used for endless war, do we? Even if full global control ever happened, the people would pay the price, even still for the luxuries of the 1 percent who got to use whatever they wanted. Thats the scam, not climate change, but the fact those pushing the agenda are the ones causing it, and profiting every step as you get more broke.

"why do we stop ourselves from producing energy and materials in the safest, cleanest ways" From the rest of your comment I can assume that you are talking about LNG and not renewable energy. LNG is cleaner than oil and coal but it is still far dirtier than renewable energy and nuclear energy.
"And the EV situation doesn't help, look into the mining and extraction processes." You focus on one thing and dont see the entire picture. EVs are much cleaner(less CO2 emissions) than gasoline/diesel vehicles during their entire "life cycle".
"After those batteries are made, then you still have to charge them, again... how?" Renewable energy, very simple.
"So expensive that they never pay themselves off?" I really dont know where you get that from but that is only if you get scammed by the seller.
"You really think the places we buy our resources from will ever change?" The rest of the world is changing faster than America.
"We dont use hydro energy properly at all either." Some people do if they have that option but not all.
"In a single homemade waste gate, I can chain 10 100 amp alternators from a 200 gallon a minute flow tube and produce enough energy to run my own home." It is awesome that you are able to do that but most people do not have access to that water flow.
"Nordstrom alone was the most destructive situation ever seen ecologically speaking." Well, that is debatable. I would say the BP oil spill was worse.
You have no clue what you are talking about, but I appreciate your ability to regurgitate silly talking points!
Because it's not caused by humans. It's the inner workings of the planet.
@@MasterBlaster-pe5os I'll need you to go down there and take measurements. You will be remembered.
Manbearpig is real!
The Earth should slow down because of Angular momentum and make longer Night Time Cooling.
The Earth will slow down, but there is always a side of the Earth that is facing the sun. There will be no change because of this effect.
@@trevx3680 The Sun will still hit all of its marks but night time cooling will be longer and its not a 1+1 equation like your ignorance is showing.
@@woodchipgardens9084 and the day heating will be longer.
@@trevx3680 the sun hitting all of its marks on the ground does not equal more heat, longer freezing period does mean more ice accumulation, its not a 1+1 equation.
@@woodchipgardens9084 Lol. The sun heating the ground for longer DOES mean more heat.
Wait, if I did physics correctly, L = r X p, which means it's dependent on mass, but ice melting into water is still the same mass, so how does it slow Earth by that much??
I smell bull shite personally.
Because the mass isn't sitting at the same radius anymore. In this case, L = Iω is more useful. When sea ice melts from a taller landmass down to sea level, the moment of inertia I reduces (remember, that's an integral of mass distribution relative to the radius at each integrated element), causing the angular velocity ω to increase proportionally. The guy in the video compares it to an ice skater tucking their arms in to spin faster despite no external force, because their mass moves closer to the center of rotation.
There was a time when there we no ice caps on the earth and all living creatures tens upon tens of millions of years ago still managed to adapt..a second more a second less makes no difference at all ..remember your concept of time when you were ten yrs old ..I don't. never worried about it until the internet came along...
do your own research. the issue is the melting is occurring at a rate unprecedented since possibly the great meteor impact that caused the extinction of the dinosaurs. entirely by man's emitting tons upon tons of CO2 each day over the last 100 yrs especially.
