Glad people are looking at the WAIS. Just looking at past interglacials, I'd say odds are good that it will collapse...eventually. But blaming it on "emissions" when it's collapsed in the past without "emissions" is absurd. Having researched this issue for a number of years while researching gas physics, let me throw this at you. Our solar system has a couple of excellent planet-sized gas physics experiments floating around we can refer to. One of them is called Venus. Now Earth has a 1bar surface pressure and an atmosphere with .04% CO2. Venus has an atmosphere with 96.5% CO2 and at 49.5km in altitude, it has an atmospheric pressure of 1bar. The temperature you find there is 151F or 66C. If we moved Earth .72 AU from the sun, what would its temperature be where air pressure is 1bar? There is a nice Planetary Temperature Calculator at the Indiana University website. Just move the default Earth-like planet to .72 AU and calculate. Let me know what you find out.

@truthisfree7297 The problem is that when the standard CC models are projected in the future, they don't always predict well what is going to happen. Perhaps one of the most (in)famous cases is the amount of ice in the Arctic. A scientific model that doesn't make right predictions is not a scientific model. It has simply been "falsified " and needs to be revised or dismissed. When high-profile scientists appear in the media announcing dramatic predictions that don't happen, it , naturally, causes a discredit for that science branch. This excessive love for making dramatic public announcements is an error committed by a number of scientists in CC. They are guilty of the skepticism of many people, it is not the people's culprit.

Something that is pretty obvious, but I don't hear discussed is that Antarctica itself will experience the very same sea level rise that we will. In fact, being a major source of meltwater, in real time the seas would be slightly higher there than elsewhere since the waters have to move outward from the melting ice at a relatively slow speed. So, while we are busy worrying about our coastlines in the industrialized world, Antarctica will be experiencing INCREASED intrusion from its own meltwater additions to its own coastlines, causing a feedback loop of accelerating melt from intrusion alone.
@reuireuiop0

Antarctic melt will kind of lift it's own glaciers, wherever these are resting on (current) sub-sealevel bedrock. Those glacier tongues will then start to melt faster or even break apart by calving, as deep water glacial cliffs are not stable. A large part of West Antarctica bedrock is lower than the oceans around it, ice free WA is kind of a large peninsula surrounded by an archipelago. Most of its ice sheet will disappear when the waters get underneath, that's over 3 to 5 of rising seas. If those sheets start calving, things could develop unexpectedly quick.

There is an opposite effect too. All the ice of antarctica has a huge mass, which affects the local gravity, pulling the oceans around it slightly higher. When the ice melts, that effect is reduced. Meaning sea levels rise less around antarctica and greenland than elsewhere. Which of these opposing effects will win? I dunno.

The models don't incorporate these under ice effects, they also don't include increasing methane levels and methane releases due to tundra melting. Given the models are conservative to begin with - getting funding requires not being "too radical" - we are finding the models used by the IPCC all fall short of predicting the actual changes we have been experiencing. Look up "Atmospheric Energy Imbalance: Global Warming in the Pipeline" Oxford University Press: Only half the heat entering is escaping. The amount retained is increasing exponentially. The amount retained doubled in the 18 years of direct measurement via satellite. Follow what Dr. James Hansen, one of the authors, is saying about this. Our situation is worse than most policy makers and many scientists realize. Much worse. To paraphrase Hansen, "It's hot. It will be hotter. Not everyone sees this yet. They will."

One additional point I don’t see addressed too often; when a point force load is removed from one part of the planet’s surface ( eg. lots of ice) , then the land under it rises, which also will other land masses around the world. So, even though I’ve read the calculation that if/when all the Antarctic ice melts, sea level will rise approx 200’ (+/- 60m) it may actually seem higher as the land beneath us sinks. Einstein expressed some concern that the ice might not be evenly distributed on the South Pole, which might also cause some planetary “wobble” to its rotation. Minor on a planetary scale, but perhaps major on a human scale. Fault lines could be more active and dormant volcanoes might erupt. Hard to know without better models.

None are cutting 2% of today's level of fossil trade licenses per month down toward zero by 2030, the minimum action needed. And Sea Level Rise, flagship though it is, is like 40th from the top of the outcomes that will hurt you, hurt your economy, crush your options and inflame your miseries. Storm surge is worse. Beryl is the flagship of the direction of hurricanes, which will become year-round on every coast every two years by 2080 at latest. Heat will exceed habitable level in a third of populated areas by 2060 for days at a time annually.

That warming scaled over the size of an ice sheet makes it ripple and crack like popcorn, expanding crevasses. While that pushes about 0.04% of Arctic ice outward from the centroid on land, it also weakens the ice so gravity pushes many times as much mass out onto the sea, like a slow motion splatter. These processes interact with the ones in the video (and other mechanisms), so Physics hates us.

Hi, nice explanation. That periodic motion due to tides makes me think of of fatigue stress in the ice... It's very difficult to explain to people that, when a glacier is resting on the seafloor, you don't need all the ice to melt to get the final effect, it's enough that it starts to float instead of being in contact with the seafloor. Archimedes' principle takes care of the rest. Minor suggestion for improvement: at 3:23 the lighting is very harsh. Either try to avoid shooting in the mid hours of the day, or use a reflector on the opposite side of the sun, so that shadows are brightened up and then all the scene can be dimmed a bit down. Also, I don't know if the lens was dirty or not well focused, it seems to me there is a lack of microcontrast.

Atmospheric rivers... Heat domes... Wet bulb conditions... Tectonic uplifting effects due to the ice mass in Antarctica and Greenland facilitating increasing volcanic activities as well as tsunamis, earthquakes, rifting events, landslides and other instabilities... The atmosphere is holding far more moisture with each fraction of a degree of temperature than most people recognize. It is now capable of dropping three feet or one meter of rain in relatively short period time in places where 1/3 of that was previously a rare once in long time event. The climate instabilities are not likely to remain in a linear pattern based upon our past understanding of the past conditions. But rather leap into a nonlinear progression of energy transfers and new cycles which we can’t imagine basing the outcomes on linear patterns of the past stable conditions. Once the methane release from the taiga and permafrost regions becomes a exponential release pattern of causality... the methane hiccups are going to create whole new systems. The geological records show strange patterns such as the Caribbean storms if i recall correctly approximately 40,000 years ago that rolled house sized boulders about in huge storms and tsunami sized waves... Curiously perhaps totally unrelated or perhaps related... Wooly mammoths have been discovered that where eating spring flowers and they were “flash frozen”... so that the flowers scents were experienced by the researchers who dissected the mammoth... Unfortunately as far as I know... there is not enough information to facilitate understanding what was happening.... Those events could be separated by a thousand years or more... Or they could be within a unrecognized mega methane hiccup period of twenty eight to say a hundred twelve year period... But super storms similar to the “Red Spot” on Jupiter might be a thing... With a atmospheric thermal inversion event that creates a edge of space to the surface of the northern and southern poles and latitudes... inducing a Ice Age as a result of the warming... probably after the methane hiccups create a hot house swampy environment event... With the 28 year cycle of methane to carbon dioxide creating a triggering event of some kind. The increases in volcanic activity might provide some cooling effects giving us more time... But might create a different environment entirely opening the door to something totally unexpected. Even the tilt and rotation of the Earth could be affected... as the spinning ball is destabilized by the changing positions of masses that have been stable for millennia.

1 cm SLR = 7 m land loss on sandy shores via coastal erosion (depending on slope) excluding storm surge. Already reports of large-scale coastal erosion in France & UK amounting to billions in property damage & loss. It's estimated that the UK could lose millions of houses along its vast coastline. The UK (like many other countries) already has a housing crisis - it won't be able to afford to keep up with new demand, let alone replace homes lost due to coastal erosion (it's a complex issue oversimplified in this example). Much critical infrastructure is also located along coastlines - it will cost billions to defend, move or replace! Another impact of SLR never discussed is rising water tables near the coast - not good for various infrastructure. MORE cost to tax payers already experiencing cost of living challenges. Also, if there's an overuse of ground water extraction in coastal areas (eg due to drought) then salt water intrusion of aquifers occurs - this has very serious health impacts especially for women & children. Eventually these water sources can no longer by used. Loss of agri farmland also occurs (or salt water tolerant crops have to be planted). SLR is a perfect example of enviro change resulting in biodiversity loss, economic loss & damage, awa social impacts & distress (eg many people becoming homeless, community fragmentation, poverty (if uninsured) & decreasing quality of life etc). Climate change isn't just about extreme weather. Climate change not only causes enviro damage (very few people care about this), but it impacts the economy in many subtle & not so subtle ways awa social cohesion & quality of life, and will require billions in defence & adaptation (if still possible) that would otherwise be allocated to critical social support services (such as food security, cities, health, education & infrastructure etc). Nature is forgiving up to a point and then it collapses - "fixing" it becomes extremely difficult & expensive and can take decades even centuries (there's no CTRL-Z for the enviro).

Do you agree that means: a) the 66m-80m of potential SLR this time b) will happen in about 400 years, c) at a pace of about 20 cm per year on average, d) at a cost of ~$1 Trillion USD per cm?

New high-resolution maps of the seafloor halfway between Tasmania and Antarctica have revealed a chain of underwater volcanoes whose towering peaks may sculpt ocean currents above. The submarine volcanoes, or seamounts, sit 13,000 feet (4,000 meters) below the waves and directly in the path of the strongest ocean current on Earth - the Antarctic Circumpolar Current - which flows clockwise around Antarctica and acts as a barrier that helps keep the icy continent frozen. Now, scientists have mapped an area where this barrier appears to be leaking, which is enabling swirls of warm water to reach the shores of Antarctica. The region is a "gateway where heat is funneled toward Antarctica, contributing to ice melt and sea level rise," Benoit Legresy, the chief scientist on the mapping expedition and a sea level scientist at the University of Tasmania, said in a statement.

@DrGilbz, not bad at all... however I still maintain that you haven't *begun* this conversation unless you state the following: the transient response of a positive feedback cycle (aka tipped tipping point) in feedback control theory is an *exponential function of time*. It's an avalanche. An arbitrarily small perturbation that triggers such an avalanche can lead to an arbitrarily large change in the state of the system in question. The gain in some sense in terms of d[momentum]/d[energy expended] trends towards oo... That's for starters. The second thing I would add is that "the conversation about climate change begins and ends with feedback cycles. Nothing else is even relevant in comparison". If people understand feedback cycles, they understand the implications of climate change and vice-versa. It's the side-effects of our actions that trigger other side effects that trigger yet more side-effects that will rule our destiny, so to speak. I'm writing a chapter for a book right now (with professors from the U.K. as a matter of fact...). I've done quite a lot of reading on these topics by now, and many other topics that 99% of humans would fail to associate with climate change... Stuff like pollution, biodiversity loss, changes to the Surface Micro Layer, coral health, forest fires, ground water extraction, invasive insects, the urban heat island affect, changes that we're having on the water cycle, the AMOC of course, and many other kinds of feedbacks that cross between the human sphere and the physical one. People, including many an IPCC scientist are still looking at the world through a straw. And that is why decade upon decade upon decade our best-case scenario now looks worse than the worst case scenario that was being predicted 10 years ago. We're utterly failing to generate 0 mean error estimates. Our innovations sequence is pink. We have failed to generate a minimum variance unbiased estimator. Our error residuals are correlated. I can say it in 10 different ways... but seeing as few people have ever studied stochastics, that probably won't mean much to many of the readers. "Agriculture is the Achilles Heel of Humanity" says Naomi Klein. Smart woman. Sea level rise is going to wipe out most of the world's rice production which supplies 20% of our calories. Salt water intrusion is having a serious impact on coastal farmland. The wet bulb effect. Extreme precipitation, the insects, ground water depletion... a loss of pollinators... All of these things are going to be impacting our society in serious ways within 20 years. There are currently 634 million people who will be directly impacted by sea level rise... and I am not estimating that'll be come 2100, but more like 2045-2050. I listened to a NASA Goddard scientist say "the sea level rise I began my career thinking would happen by 2100 I now estimate will happen by 2050". We continue to underestimate many, many different factors on all sides... let alone the covariance between these factors. And that'll be devastating. Sea level rise is going to kill more people than many other factors you mentioned... because it's going to lead people to fight with other people. Scarcity breeds aggression, yeah? Between the wet bulb effect and sea level rise I anticipate ~2 billion people in flight by 2040. And there are more feedback cycles in play than I can possibly write about here. I was invited to give a talk at Sunrun, an American residential solar installation company... and I talked for an hour and didn't finish. I would need many hours even to cover the surface level content. People are *radically* underestimating how bad things can get and how fast. We are linear minded beings that deal incredibly poorly with exponential time phenomena. That goes for the Japanese at the end of WWII who said "we're not afraid of any new fangled bomb, it's an empty threat". It goes for president Trump when he eliminated the pandemic response dept of the US government. It goes for how we content with forest fires. It applies to all the spenders out there who rack up debts on credit cards they can't pay off, and therefore take out a 2nd credit card to try to pay off the first, which just compounds the problem. And it goes for people's inability to anticipate the massive effects technology has had... everything from trains, combustion engines, microchips, lasers, digital cameras, the internet, AI technology, etc... People don't understand that when you use technological outputs as inputs to make more technology (e.g. CAD software, programming languages, wikipedia, continuous integration tools, etc...) that is an exponential growth process. It's a process that has 'babies' in some sense where those babies grow up to have more babies... and things keep replicating from there. Which reminds me of how serious it is that we have 8 billion people. According to the environmentalist Bill McKibben, if we all want to live the kind of lifestyles that people live in the U.K., let alone the U.S., then there are resources for 680 million people to live on this planet in that fashion. We currently have 12x more people than that, and we're going to have 9.7 billion people by 2080 a recent student suggested (except that study is making the same massive extrapolation errors that everyone else is. Our society is going to come flying off its rocker by 2045... because there are more feedback effects in play here than 99.99999% of the world has thought about before). I should mention that McKibben said "if we lose the U.S. wheat crop for 1 year from freak weather events (or nasty bacteria, or whatever...), that's a national disaster. If we lose it for 2 years in a row, that's a recipe for WW3". I'll conclude this comment with the following observation: forget about what happens when there's no more food on the shelves. That's not actually the weak link. Even if the prices of food merely triple, that in and of itself will end our civilization. Because the have nots will go to war with the haves. In the US 20% of the population spends > 33% of their income on food. In Kenya it's like 56% of the population that spends more than 33% of its income on food. If food prices triple, we're talking about 20% or 30% of 8 billion people who are going hungry, and they won't be happy about it. Meanwhile, we live in a world where thousands of farmers feed billions of people. A single farmer can feed 10 million people/year. And that's why we have so many people living in cities. So guess what happens if riots break out and everyone is fighting over food? It means people aren't working and society breaks down. And it means supply lines fail and replacement parts aren't being made and there's no ability to keep our technological base well oiled and maintained. We live in a world where it takes the concerted efforts of many millions of people to e.g. create microchips that go in the computers that run tractors... If you think about the rubber, steel, oil, aluminum, phosphorous, urea, the battery technology, the GPS technology, materials for sensors and displays, etc, etc... there's a pyramid there of millions of people who must *collaborate* in order for these machines to keep running. We can't be collaborating if we're busy fighting... or if there are hordes of 100 million refugees on every side of every border. And btw, if terrorists are occupying the Suez canal, and drought is impacting the Panama canal... we are getting pushed higher and higher up a ladder of technological and fossil fueled dependence from which there's no easy way down. If supply lines aren't running, we have issues. If people aren't being fed, we have something far worse than WWIII. We have complete mayhem 28 days later style. The roman empire lasted for 500 years. How long did it take to tear down the city of Rome in the end? 5 days. That's nonlinearity for you. And it's time that the world population learns to adopt mental models that are appropriate for our times.

I might also throw in a little tidbit of information such as e.g. we have sunk 500e21 joules in the world's oceans... This comes directly from an IPCC report. If that number doesn't mean anything to you, you can put it in terms of e.g. 119 million 1 megaton hydrogen bombs of heat. And the 100 million barrels of oil we burn per day have the energy equivalent of 15 Hiroshima sized nuclear bombs exploding every second of every day, year in ... year out. 91% of that energy goes into the ocean, 4% into ice, 4% into the land and just 1% into the atmosphere. So once again, if you're trying to assess how much global warming there has been by how our air temperature feels, you're missing 99% of the story! Literally!

Isostatic movements of earth crust will go on for a long time _after_ the ice sheet is gone, and that may take a couple of centuries. The isostatic bounce back will then take place over millennia. In Europe it is stall happening, don't no for America, but seen the enormous extent of the laurentide and cordilleran I've sheets, this is likely to still continue as well. However, as the bounce back _follows_ after the melt, it will not work as a process that might slow down the breakdown of ice fields by lifting them out of the water. It's reactive, to the mass of ice having disappeared.

Besides the effect of the tide going up and down twice each day, pumping the deep salty water in and blowing water out of the cavity under the ice, there is possibly another effect. As this slightly warmer, salty water melts the fresh water ice, the mix is lighter than the circumpolar deep salty water. It would be expected to flow upward along the ice ceiling. The only way this could happen if if it caused more salty water to flow under the ice.

Also depends on where - west Antarctica is mainly melting from below, but Antarctic peninsula (and Greenland) are mostly melting from above

Please help me write balloon manufacturers so we can make a 10-km balloon this way we can send cold air from the upper atmosphere to the water and make the water freeze and put the Arctic in any location

The thing that struck me as really important was the bit about tides lifting the ice sheets and letting warmer water get further under them. I seems to me that if you take a tide now, and it lets warm water in to what ever distance it does at the moment and this causes melting you are also seeing the next tide becoming that much higher and then lifting the ice even more. The more water you have the larger the tides right? So a larger tide causes deeper intrusion of warm water leading to more melting which leads to more water causing bigger tidal range and so on, over and over until there's no more ice to lift... Does that make sense? Because it seems to me that this process would just accelerate itself.

Insane how denial comments are still a thing. I hope they're all bots that rush on key words like climate change
