The phrase "faster than previously thought" is the dominant theme of climate science. Along with "greater than anticipated". Like "unprecedented" has become the dominant theme of our politics.

@@christianfaust5141 So, you want to stop burning coal, let's say, as a start? Wellllll.......... Here's what happens. As coal combustion in air is the source of most of the SO2 and black soot at higher altitude, ceasing coal use would remove much of these "pollutants" which will reduce the acidification of the seas and land, and reduce the darkening of ice which serve to melt ice and reduce darkening of land surfaces. These are good things, BUT............These two "pollutants" also provide a sort of aerosol parasol, the "aerosol masking effect" which keeps the global average surface temperature about 0.6 to 1C. cooler. So, if you stop burning coal, you reduce the long term heating of the biosphere and reduce the melt rate of ice and the acidification of land and water, but you will allow the near instantaneous spiking of global temperatures. If you don't survive the short term effects, the benefits of the long term effects are moot.
A fried of mine is a climate scientist was worried about the Pine Island and Thwaited glaciers starting in November 2022. He noticed that the iceberg blocking the PIG bay had started moving. He predicted a possible collapse, but was surprised by the extent of it over both glaciers within 3 days. But he was even more worried about the silence from not only the media but also the climate world. He started a group to discuss the Antarctic, and he invited me. The situation is worse than you talked about, since Deep Ocean Heat has caused the Swiss Cheesification of the ice barriers. We just came out of the Winter Melt Season, and the sea ice extent is off the charts, and faster than expected. Funny, just when they lost the Antarctic they decided to allow the Middle East conflict to have their 12 box cutter moment.
water gets swallowed whole by cities and sent to the water dump because they dont want flooding bla bla bla to bottle water to states dealing with their water poorly leaving lakes and rivers that were up for hundreds of years russia has this nuclear boat they have done some massive projects withi imagine if america started making mega cities with nucelear energy and sending the waste to the moon to fuel experiments or iss est
I like the term Swiss Cheeseification… that is a very accurate description. Those glaciers will probably do a runaway into the sea and cause massive, impossible to imagine swift rises in the Ocean levels Worldwide. Ocean surges, floods never seen by Humans, death and destruction on an unimaginable scale. This scenario could be coming to Communities near you as soon as next Summer when the super El Niño Summer roles around to the Northern Hemisphere after hitting the Southern Hemisphere in the soon to come Southern Hemisphere Summer.
Antarctica is the least of our worries. Disastrous harvests in the US Midwest will bring an end to humanity in the near future. We’ll be long 6 feet under before Antarctica goes.
I live on your neighbouring Island and my experience of the outdoors over my last 20 yrs informs me that the climate is changing, and recently this is accelerating. The natural world is full of clues to those of us who live and work in the actual countryside are qualified to detect ;leaves dropping later animals not hibernating Swallows not departing Salmon no longer present like they used to be
I have noticed from 65 years of observation that I get colder in Winter and hotter in Summer. And I can’t walk as far as I used to nor as fast. I don’t know what it means but I’m sure it’s very important.
I've been following this channel for the past three years. I used to find them mildly irritating because most concerned the promise offered by this or that techno-fix. And my view is relatively simple: more techno-industrial 'progress' will not and can not hope to solve the problems created by techno-industrial 'progress'. What's needed is to manage global population and to begin to produce and consume far less of everything. So I have been pleased to discern on this channel a greater focus on the very real dangers poses by climate change rather than what I regard as largely unrealistic aspirations to see us through the coming crises with more technology. While people continue to believe that some 'clever people' will come up with a range of magic bullets, there will be far less pressure from below to adopt measures that might actually help.
@@Lyra0966 To produce less and consume less techno-industrial processes need to be optimised which they are. Population decline has been an established fact since the 1960's and was theorised already in the mid 1800's. Both are large scale global events and take time. We are starting to see them happen now politics is what is slowing them down from happening faster sadly.
While I agree that there are a lot of episodes about emerging technologies that when viewed in a more global context feel kinda silly, we're not going to survive without technology. Even if we wanted to transitioning to a low-carbon agrarian society is probably not even possible. It's been good to see more episodes about more mature technology we can and are using today like the Flow batteries and pumped-hydro, but I still want to know about developments in things like wave powered reverse osmosis or algae based carbon capture. And for all the practical solutions we could be enacting today in our cities I watch urbanists who educate and advocate for walkable/bikeable cities. @@Lyra0966

@@rogerstone3068 All this is highly speculative, unknown and very long term if it happens at all and the only reason all the media focus is on Antarctic sea ice in October is because they need to draw focus away from this year's Arctic sea ice minimum which was EXACTLY the same as in 2007 when media sea ice shit storm started. They don't tell you ZERO not change in 14 years, they say LOOK OVER HERE! Forget about "the canary in the coal mine". LOOK OVER HERE!
I have heard that the Arctic and Greenland ice cover has actually increased in the last few years, and that "global average temperatures" have been falling slowly since 2016 (NOAA). This will probably affect the Antarctic in a year or two...
Might want to speak about the Amazon River AND the Mississippi Rivers. Extreme low waters. People of the US are not aware of the extreme droughts that are happening.
Another possible "feedback loopy" scenario that could accelerate ice sheet loss is the potential for increased seismic activity due to the rapid reduction in the immense weight of the ice sheets as they calve into the ocean. Earthquakes would loosen the ice's grip on the bedrock and cause cracking, both of which will accelerate ice loss. This may be decades away and it is impossible to predict its extent.
The subsurface rock will rise with the reduction in ice burden. This will lift the ice sheets and make them more stable. A rare example of a negative feedback!

One of the saddest things was the mass death of emperor penguin babies. Literally no mainstream media reported on it. Over 10,000 died due to drowning.
I was lucky enough to help with penguin scientists in the Ross sea. Penguins are truly delightful and interesting animals,.. even though an Emperor took a bite of my cheek🙃

Unfortunately, it's likely already too late. The answers lie with the people.

SO glad you called this out again. As awful as the events of the middle east and eastern Europe are, the potential catastrophe looming from the Antarctica thawing are even more sobering. We have unleashed a chain of events that are now humanly unstoppable. There is only one option left as we face the 6th Extinction.

If it was true those decades ago that if we took decisive action then to prevent the worst possible outcome the statements that if we take decisive action today we can stop the worst from happening is at best tragicomical.
We don't know this. As far as people and their lives go, the Antarctica is not known to be a human created risk, and we don't know that there is any risk at all yet. We really don't have enough information. But a war can kill tons of people really quickly. That's why doctors treat heart attacks first, and worry about all other health issues later. Because the later does nothing for the patient if they are dead. This is why we have to focus on issues like war over theories about a continent we know very little about.

It is so scary and we are so seemingly powerless. We've been raising our voices for years but the powers that be don't appear to care or just act annoyed or worse, hostile and aggressive. It's so frustrating.
I think even those you think are 'in power' are effectively powerless too. Nobody actually knows what can be practically done without causing massive upheaval and distress. This situation we've dug ourselves into is just too damn complicated. We're only able to very tentatively change little and effectively insignificant aspects of our lives at a time and there's often considerable resistance against even that.
@@UCCLdIk6R5ECGtaGm7oqO-TQ I agree with some of what you said, but we *do* know what can practically be done. The problem is the greed of the vested interests that are holding back the progress that diminishes their power and profits. The barriers are political, not scientific.
@@UCCLdIk6R5ECGtaGm7oqO-TQ No, that's not the case. It's not too complicated. We know exactly what to do. It's a political problem. To the OP's point, this means that we are not powerless. We can work to elect people who will do the right thing. In America this means defeating Republicans. The best thing any one person can do to help the climate is to vote the denialists out. When Democrats finally got a bit of power in America, we got the "Inflation Reduction Act", which is a huge climate bill that is causing a revolution in the way we use energy. That is what happens when you elect the right people.
What is so frustrating is that we are increasing the temperatures of the oceans not because we want to, but because human activity and the need to, say, heat our homes is throwing a stick in the spokes as far as slowing down carbon emissions. I am not a climate scientist, but I think we all have to realize that the 70% of the earth's freshwater that is currently ice in antarctica is sooner than we think going to become liquid water very, very soon and that is the straw that breaks the camel's back as far as I am concerned. Because this surely will mean that the AMOC becomes dead in its tracks and when that happens the earth becomes a whole new planet.
And where is your proof that humans are the cause of climate change? If you have this proof come and tell. As long as there have been humans on this planet, there have been preachers saying the sins of man cause bad weather, earthquakes, crops to fail etc. The common solution to repent is usually for some sort of offering to appease the Gods.
It's going to melt either way. And then it'll freeze again. All it takes is for a chunk of asteroid, or a big spew from a volcanic eruption, or even more likely, a radiant CME burst to wipe us all out within a years time. When I was a child, I always wondered why people don't just invent better infrastructure and methods of dealing with natural disasters. Some do for earthquakes, but not enough for other disasters though like tornadoes and floods. At this point, just move somewhere else and invest in your bloodline's future. Use stone as a building material, or build your house underground in a hillside. You'll be fine and your family will own one valuable piece of property. At least for you, you'd have low insurance premiums
A concern about AMOC stopping is that while it would mean Europe would not be getting the warmer equatorial water and become much colder, the equator would retain that warm water. This would increase the difference between the north and the equator which would likely lead to much more extreme weather patterns.

I moved to south Brazil 3 yrs ago. What I have observed are the Low systems that used to tightly circle Anarctica, are now widening their paths. The lows are spinning off and effecting Australia and South America. Sending sub tropical cyclones up the coast of Argentina and Brazil. I expect cyclones to become a regular occurrence. Also there appears to be a river flowing over the Andes, from the west, and turning into flooding in Southern Brazil.
Hi from the very south of mainland Australia. We are observing those changes on this side of the globe. I agree with the climate scientist James Hanson in his predictions for catastrophic wind. Our building codes are very lax, we are in no way ready for what is about to come.
It's a weakened jet stream causing that by a reduced temperature differential between the pole and mid latitudes. The same has been happening in the northern hemisphere.

The inexorably rising Earth Energy Imbalance (EEI) (sustained by an irreversible total cumulation of greenhouse gases), subsumes all regional variations of land & ocean temperatures. The EEI fuels & exacerbates adverse & extreme consequences to our biosphere (eg warming, melting, flooding), on a pathway to severe degradation of, & shrinkage to, our habitat, presenting an existential threat to the survival of our species. We are getting closer to the point when untried & untested geoengineering will be forced upon us as a desperature measure to try to stop the rot

@@tsaicioI don't know the amount, but it's obviously not nonsense, because the oceans interface with the atmosphere over a vast area and the laws of thermodynamics mean that both try to come to equilibrium. Imagine a completely enclosed fish tank half-full of water - pump the air in the top through a cooler and make it cold then let it sit - eventually the heat from the water moves into the air. Pump that air through a heater and let it sit and eventually the heat from the air moves into the water. That's just basic physics and why fridges work.
@@tsaicio Not nonsense. Liquid water has a much higher heat capacity than air. It can absorb much more energy than air for a given temperature change. Specifically, at sea level one cubic meter of water absorbs 4,184,000 Joules to produce a temperature change of one degree C. A cubic meter of air absorbs 840 Joules for the same temperature change. A factor of about 5 thousand times as much energy.
@@tsaicio My simple uneducated explanation. There are many more particles in the water vs the air. If you heat up your stove, the air will heat up almost instantly, but put a small pot of water on, that same airspace will be room temperature comfortable for a few minutes. Also given how deep the oceans are, the volume of the ocean vs the atmosphere is probably at least a 1:4 ratio.
Up until the last 150 years the temperature has been remarkably stable for near 10000 years . Even though temperatures are rocketing away now it was slow at first because most excess heating had been absorbed and `buried `in the sea and you have to put a massive amount of heat to actually melt ice , once melted the water heats up far faster . That and buried heated water now resurfacing and the huge amount of GHG (effectively a blanket that like a blanket takes time for heat to reach a new equilibrium ) is causing a monumental temperature rise and more is baked in as were at least 30 years off equilibrium with what we have now ..and GHG`s are rising at there fastest ever rate even after decades of dire warnings .
In 1971 my college professor interrupted our electronics class to talk about global warming and how it is affecting the jet stream. If the jet stream path starts changing to extremes it will created extremes in weather. That's the first time I became aware of global warming, just by bringing up the subject to class rooms
I was also made aware of problems with the planet's climate in the early 70's. At the time, it seemed that this information/knowledge was common. we have continued to act in a very restrained manner now for fifty year while this problem has turned into a monster. the problem is truely the way we think and act
Given all the wars raging at the monent & most likely escalating, I wonder who gets us first, mother nature or nuclear holocaust. In both cases, mankind is the only species committing either a slow or an instant suicide.
Thanks Dave, I can’t un-see that penguin now. As a suggestion for a further edition - the media tends to focus on average temperature change, however it’s the extremes which have the greatest impact. It would be useful to understand what modelling and empirical data says about the statistical spread of climate change.
I see that NZ has had a recent political lurch to the right. Will that mean a loosening of their environmental attitude? Possibly. The ocean currents slowing down to a stall reminds me of an early outcome theory around the 1990s when it was said that the human living zones may become banded into fairly tight latitudes, with the extremes almost permanently covered in ice right down to northern Europe, with similar results in the southern hemisphere. As far as I remember, this didn't take into full account the rise in global temperature or the terms we used to use, the Earth's energy, or heat, budget. But what it meant was that Northern Europe, America, Asia, echoed in the southern hemisphere, would have incredibly severe cold winters and very short summers, while southern Europe and those latitudes either side of the equator would be the only liveable bands for the global population. It ain't pretty. We've moved away from that singular theory idea since, but it's influence will be felt in the mix.
With its population of about 5.2 million, NZ is 0.06% of the world's population, and it emits about 0.14% of global emissions. The majority of NZ's emissions are due to production of sufficient food to support about 100 million people - mostly in other countries. So if NZ was to blink out of existence and zero its emissions it would make no meaningful difference to the climate, but a lot of folk would miss out on their steak, lamb and cheese. The flavour of its government makes no difference to the big picture at all.
Already the situation was hopeless under the previous Labour government. We even got the honour of a telling off by the WEF no less (yes the WEF lol) for not even being on track to meet our very unambitious domestic target. Things now will get even worse. One of the parties in the coalition (Act) wants to scrap the entire framework that sets domestic targets and requires governments to come up with emission reduction plans. NZ has a 'clean green' reputation but the reality has always been different - 70% of rivers are heavily polluted with nitrate runoff and emissions have been sky high for a long time.
@@philip88154 NZ's emissions would ease if they were spread over the whole population served by the country's primary production. That would put the 'blame' for those emissions where they should lie (in countries that consume the produce), and ease the need to impose draconian emission controls within the country. While certainly there is no room for complacency, NZ should be more concerned with developing and implementing adaptations to the expected climate change and sea level rise than with major economy-wrecking emission cuts, IMHO.
@@nigelwilliams7920 Even if you measure the consumption based emissions (which excludes what we export), our emissions are still between 8-9t per capita CO2-e. They need to be 3t on average globally by 2030 to keep warming between 1.5-2 degrees. Responsibility for emissions should lie both with the country of production and consumption. There is a lot of research showing that there needs to be a shift away from meat and dairy consumption globally to meet targets. NZ as a major producer must do it's fair share, we are after all also a relatively wealthy country by global standards as well.
This is a reasonable thought. A kind of reason has gotten us where we are however. Perhaps humans and our wielded power are the problem. Too much success and plenty of time to philosophize has created a monster that puts people first and the planet far down the line. The experiment in power seems like it has run its course.
Good piece. I wish you would mention the effect of ice falling into the ocean, assuming it is not floating and therefore not subject to buoyancy principles, will raise the ocean water level. So much of the focus is on melted water, but ice chucks do the same thing but in a more punctuated manner.
@@beezybeez4207 Because, if it is already floating in the ocean it will not change the effective displaced volume of liquid and raise the level of the ocean surface since it is already "floating" in the water. If it is above the water and then enters the water its volume immediately becomes subject to Archimedes Principle and adds to the total volume of water, raising sea levels.
@@beezybeez4207 The structure of Antarctica is such that a large part of it is above the water level and is not floating. The mountain ranges and other structures are supporting ice that will be capable of entering the water and raise sea levels without melting. The notion of an assumption is a way of predicating a premise in order that the proper analysis is made.

you are right because if the ice goes then all that fresh water will dilute the salt content and slow down the movement of heat around the world and can have an effect on the weather.
It's not just that, if the current slows down so do the tiny nutrients that support the food chain of life in the oceans. There is already a dying off happening in spots around the world including small pockets where oxygen is missing, poisonous alge will become more frequent due to the warmth of the oceans. Those at the top of the food chain like Sharks, whales, killer whales, dolphins have been observed at different points of making a shift or trying to adjust to survive. It's not happening everywhere, but enough that we should take notice, these are the seas 'canaries in the mine' I believe sometime in the future, we will need to make a tough decision to leave the ocean alone for a few seasons so it can adjust and replenish itself as it will not be able to adjust, support humans and sealife while it is depleted. They don't call me Cassandra for nothing... 🙄
More worrisome to me is the suggestion that modeling the emerging dynamics will not provide useful forecast (see “turbulence”). Climatologists like Jason Box and others discuss that a number of dynamics are not accounted for in current models, which lack resolution and math to include them in the models. Other techniques lack the data to approximate modeling. Beyond this, though is an implication the process can become chaotic, that is, they can’t run them too far into the future and expect them to remain accurate. If we can’t model 30 years or something along those lines, into the future, we’re in a very different world indeed.
@@Sjb-on5xt weather is not equal to climate. Modeling the latter is still a more tractable beast, but new dynamics are emerging. glacial ice melt, atmospheric rivers dropping 20 cm of rain on Greenland and Antarctica snow insulates the ice and becomes ice. rain is like acid.

I wonder why we never hear about the massive amounts of emissions that comes from jet air traffic??? If you look up the massive amounts of fuel each flight consumes it will give you something to have a think about
Just read that aviation contributes 3% of warming. Not that much, but every little bit hurts. I think that ground transportation is more significant, due to the greater number of vehicles.
Maybe because air traffic doesn't contribute much CO2. From a quick internet search it's something like 2.4% (2018) of all emissions. The number is increasing due to the number of flights increasing. Aircraft engines are some of the most efficient engines out there, and they continue to improve. Many other industries produce substantially more CO2.
I believe that the amount of emissions from flyers is huge as measured from the that individual, well beyond any other form of travel. If everyone flew, the total numbers would be astronomical. If everyone stopped it might make a small difference. Huge fuel cost increases might make a fractional dent as well. Think all the air forces on the planet are going to stop training? How about sports teams hurrying to their next arena? Do you support a team? Perhaps the reporters asking questions after games could ask about the teams "carbon fart print".
@@danielfaben5838 The OP didn't say which is worse 'per person', just that flying was a big emitter, which in comparison to other sources it's not. Or another way, if the world stops flying tomorrow we would only be stopping 2.4%/yr of Co2 from entering the atmosphere. Stop eating meat, or everyone starts carpooling, taking a bus or train, or find a better form of concrete for construction, or stop using bunker fuel and such for cargo ships or find/stop the (mostly methane) leaks from gas production, or... any single one of those would stop (some significantly) more Co2 from entering the atmosphere a year. Back to transportation, single occupancy driving Vs. long haul flying... flying is better with respect to Co2. Go to shorter flights then it driving can be better. Can't beat bus or train.
12:20 That is a vast underestimation. We saw an immediate impact on oceanic temperatures when sulfur emissions were cut in 2020. Atmospheric aerosols have been concealing climate change much more than we think. It’s probable aerosols will in fact be necessary to prevent climate doom.
In the early 70's when I was completing my mechanical engineering degree I kept my interest in the geology etc alive by attend guest lectures. A guest speaker doing research on CO2 emissions from the industrial revolution onward was trying to determine where all the CO2 went since if it stayed in the atmosphere the the percentage of this gas would have been higher. I think today we have a better handle on where it went and is going. Best regards.
@@rdelrosso1973 And now all the Oceans are becoming so acidic that the food that most sea life depends on is dying….we are coming close to the time when the Oceans will be throwing Co2 as well as methane at us. The Oceans will become so toxic that very little life will be left in them and so toxic that nobody will be able to live near them. That combined with the Sea level rise will spell doom for many of the Worlds biggest cities.
Icebergs melting does not raise the water level, ice is 2/3rds the density of water, that's the reason it floats. Ice SHELFS breaking off the Glaciers and becoming Icebergs does.
And quickly too, just as adding ice cubes to a glass raises the level of water even before the icee melts. Sea levels will begin to rise as soon as the Thwaites glacier breaks away.

Thanks Dave just another reminder that everyone must stop burning stuff now! Whilst politicians mince around everyone that can afford to make mitigation measures should unfortunately that’s rarely the case! 😟
Burning things which are primarily composed of fossil carbon. Go ahead and burn ammonia if it's manufactured from atmospheric nitrogen, water, and non-fossil carbon sourced energy.
@@simsong1188 And if we keep burning fossil fuels, it will result in famines, social chaos, poverty, war, mass migration, human extinction. So what's YOUR answer?
May the Anthropocene (Pyrocene (?)) epoch make the Permian-Triassic extinction event seem like a minor footnote in the pages of Earths history. Seems more and more likely, scenario SSP5-8.5 of the IPCC assessment may become a reality. If it does, enjoy what you can, while you still can; pity the next 3 to 5 generations to come.
Thank you so very much for your wonderful presentation. Your sense of humour despite the seriousness of the subject matter was not lost on me. You are very similar in nature to a very dear friend and past work colleague of mine called Peter. He’s from the UK. This current look at the southern ocean and Antarctica is extremely worrying and serious stuff. !! I agree. For our NZ scientists to do what they have, signals a new alarm to the world.
Bald Dave is getting rich scaring people. Climate hysteria. Meanwhile, only one hurricane hit the USA this year. I thought weather extremes were baked in????
@@mcarpenter2917 Yeah what is important is the food supply, the major grain fields and other food sources like fish and how they are affected by key levels of changes.
You're always so optimistic. I'm already making plans for my grand children to live on Antarctica and every video you're like it's not too late to reverse this.
Out of personal experience I can say that the main problem in communicating what is happening is that it is a slow process for personal human understanding and acceptance. Apart from that it is a complex system with a large number of ‘parameters’ involved. Very few people can or will understand what is happening and react with incidental remarks that lack satellite view and time perspective.
Thank you for another very insightful video. It seems like no amount of sensible data will project us into action, unless our daily lives get drastically affected. Which will happen (not?) soon enough...
Notice the ice core data he supplied only goes back 1000 years. The Vostok ice core data goes back at least 450,000 years. Why did he exclude this important data?
Malthusians have been using the same theory for 150 years that resources will outstrip supply, but humans keep keep proving them wrong. What may do it, is transitioning to alternatives fuels that rely on rare minerals.
You really need to start this when fertiliser came about from ww2, without it these people would not exist and the use of oil, energy we never had before, from that time also. People are not the cause but the result. If we found out how to refine oil 2000 years ago this population bump would have happened then.
Just saw whales with their babies in Hervey Bay in Queensland resting before their long trip to Antarctica to feed up. I remembered your last story about warming waters in Antarctica which will effect their feeding as krill will be effected by the warming waters. Another consequence of global warming. Keep up your great work.
"Overall, the Antarctic ice shelf area has grown by 5305 km² since 2009, with 18 ice shelves retreating and 16 larger shelves growing in area. Our observations show that Antarctic ice shelves gained 661 Gt of ice mass over the past decade." (Andreasen et al, 2023). It is from a paper entitled "Change in Antarctic Ice Shelf Area from 2009 to 2019". They use MODIS (Moderate Resolution Imaging Spectroradiometer) satellite data to measure the change in ice shelf calving front position and area on 34 ice shelves in Antarctica from 2009 to 2019. Also, as the mass gain (661Gt) was given, you could calculate the volume of the ice gained using the formula: Volume = Mass ÷ Density (assume Density of glacier ice 0.9167 Gt/km³). This would give you (well not you obviously) an Ice Gain Volume ≈721km³. That's how much extra of the lovely white stuff there is around Antarctica. Imagine standing in the centre of this extra ice. It would stretch beyond the horizon in all directions and would be 45 storeys high.
Thank you for having this info to hand. I had read that researchers were saying what you have written but googling for it to remind it is a nightmare when so many scientists and researchers are having their work hidden from us!
But but but this cant be true! 😮Exactly Now when third world is rising we must ban oil. Not only the viruses are smart atracking only after 20h climate is also.
That is only the "ice shelf". Using their methodology, Antartica ice shelves have gained 661Gt of mass. But, other studies show that Antartica as a whole has lost approximately 1500Gt over the same time frame. Also, if you read more than the abstract of that paper you would see where ice shelves are losing area (west and the peninsula) and growing area (east): "This study has generated a comprehensive dataset of change in ice shelf area on 34 Antarctica ice shelves over the last decade. Overall, ice shelves on the Antarctic Peninsula and West Antarctica lost areas of 6693 km2 and 5563 km2, respectively, while East Antarctic ice shelves gained 3532 km2 of ice, and the large ice shelves of Ross, Ronne, and Filchner grew by 14 028 km2 (total)."
@markvalery8632 So not "out of control" then as per the video. Antarctic ice sheet mass loss is about 90 Gt/yr (Otosaka et al, 2023). It's total mass is 24,380,000 Gt (24380000000000000 tons), so it loses less than 0.0004% of its mass annually, which I think you could reasonably round down to zero. It contributes 0.36mm to sea-level rise per year (that's essentially nothing as well). At the current rate it will take well over ¼ million years to melt, but we are due for two more glacial periods in that time. That ice is here to stay.
Is the sky 🐥 falling . Do you have any input on how to slow down the stop of world war 3 in the Middle East so that we can worry about the sky falling some more.
Great video Dave. It's clear that you put in a lot of hard work every week. These latest data are, as you said, really worrying. More so because all of the worst greenhouse gas offenders seem to be more and more in thrall to the fossil fuel industry. I'm a grandfather and I've been really worried for my grandchildren future. With the reports coming out now I'm starting to worry about my children's future. Things do seem to be getting more dire much more quickly than even the most ardent Climate Scientists thought they would. We need action now, not next year, in five years, or over the next decade. The fossil fuel industries will surely make certain that doesn't happen by plowing billions into buying off the right people! Yikes!!!
I think we are a bit too late. CO2 lifespan guarantees many decades of future warming, and we are only now just seeing the effects of what we did in the 1970’s. Imagine when the impact of the 2000-2020’s economic revolution arrive. I suggest you stop worrying and accept the inevitable. Prepare, or don’t, it doesn’t really matter because we can’t live on the moon or Mars, no matter what Elon wishes. Besides, if trump gets elected you can expect the decapitation of many of the world’s government functions. That is when the END party will really begin. Enjoy.
I had the urge to spend two years in the Antarctic when I was younger. When I found it was indeed possible, it became irresistible. It was worth going; but not so much so that I've ever wished myself back. In fairness, where I was based the lowest temperature was around -40C, not the -80 that some parts of Antarctica does indeed get. Also where we were, we only got -40 in still air: when the wind blew it got warmer on the thermometer even if it felt nastier. Again that may not be so elsewhere.
PS: I should add that our base, Halley Bay (UK), was on floating shelf ice. That's ice that has fallen as snow in the past onto the continent, but has slowly flowed off the edge at glacial speed and is now floating on the sea below. That's different from "sea ice" which is ice formed in the surface of the sea when the air temperature is below -2C (in the dark) or below some colder temperature when the sun is shining (because the sun warms the top layer of the sea). As you approach the area by ship, it breaks through the relatively thin sea ice to approach the cliffs made of what is essentially compressed snow, maybe 60 meters high, with another 150 to 200 under the water holding them up. Nobody has ice breakers that can cut through that!! They make the famous "White Cliffs of Dover" look dull in comparison :) It's that proximity to sea water that kept our base warmer than the inland bases (especially the US base at the South Pole) and the Russian base (which is at the point furthest from the sea: the so called "pole of inaccessibility"). It's the Russian winter-overing staff who get the lowest temperatures on the planet to live in, as the temperature gets steadily colder the further away from the sea you get. At Halley, and at bases on the rocky coastline of West Antarctica, the nearby presence of the sea is what makes the wind be warmer than still air. Were we worked that we lived in what was essentially a tethered iceberg? That the sea was not only a walking distance from us horizontally but also some 200 metres below? No: because there is plenty of warning when floating land ice breaks off. That's because we (not me personally, but some people at the British Antarctica Survey) understood the dynamics well enough. That may change if conditions continue to accelerate as religiously as they are at present, making bases on floating ice shelf Eventually any it will "lob off" and become an iceberg. Our base has since indeed lobbed off, so there was an iceberg around at some time with my bed in it, and the rest of our base. The next base at Halley has also been abandoned. Because they got fed up of having to build new bases every few years, the current base consists entirely of structures on skids (like giant sleds) that can be towed towards the continent as often as needed. That base has now had to be moved at least once, so at least three floating ice locations have been abandoned at Halley since I left in 1983.
@@Sjb-on5xt @Sjb-on5xt please refer to my recent reply for more background info. of course if was a one-off rise, no a rise of a few hundredths of a degree would make no almost difference at all locally. However with a 2C rise in planetary average temperature being considered dangerous by the experts, even 0.03C is 1.5% of the danger level, if repeated year on year for less than a century and over the whole planet. So yes it's enough to make me worry not for myself (already in my retirement) but for the world my grandchildren and great grandchildren will live in (assuming my daughters choose to have children). The problem, as Dave has explained, is that this is an upward trend discovered by comparing data collected from different years. 0.03C/year is another 0.3deg by 2033, and 0.8deg by 2050. However it's worse than that. This looks like the start of an accelerating change. If a car is rolling towards you at walking pace that's not a worry, but if it was stationary just now and has just started moving that might make you think it's worth getting out of the way; or better to make it stop.
When the ice is gone there is probably a sign sitting underneath the ice that says: This happened to us millions of years ago Good luck Welcome to Waterworld
I wonder if some of the previous mass extinction events in the ocean have occurred due to sudden shifts in these relatively stable marine chemical processes such as freshening/stratification.
I'm imagining that, unless the public steps up and asserts their influence, the powerful few will continue to exert their influence to instead increase pollutants that will reduce the effects of solar activity on the temperature so that they may continue on using carbon based fuels.
Unfortunately the oil,gas and coal industries have government between a rock and a hard place. The ship has sailed, I don’t think it’s possible to effectively change course at this late date . I am not optimistic about the global future.

We need to talk about Antarctica yet again. Antarctic Sea ice volume is higher now (Jan 2024) than the early 1980s, and eventhough Antarctica is into the austral summer the melt rate has slowed down and Antarctic Sea ice extent is greater than 2017.
Issue with denialism is that there always one more excuse from endless bag of excuses why not doing what is needed and necessary. it is easier to spend 2.2 trillion USD on military worldwide so we could blow our selves to smithereens easier, than actually invest part of that money to technology that will transfer our emission to be more nature friendly...
Why pay for an army if the governments can make the entire world energy poor and stop all that nasty "being fed" and "not dying from climate disasters" and "food production increasing so fast land use is falling" and "life expectancy continues to go up" and "urban populations decline with greater wealth" Instead we will make everyone poor. Only billionaires who pay the proper indulgences should be allowed to live their life as they choose. That should be delightful, because I'm sure most populations will be more peaceful with declining wealth, health, freedom, and opportunities as they watch the wealthy suggest the poor should eat bugs rather than cake.
its not denialism, its misdirection. but yeah, best use that money on weapons and not mitigation of the effects of the change. the cost of rebuilding from weather related disasters is going to be trillions and people need to get woke and start demanding that money be spent doing whatever we can to decrease the impacts and prevent damage as best as possible.

Freeman Dyson: Vegetation growth is increasing with CO2. About 1/2 of CO2 growth has gone into increased vegetaion growth. CO2 is enormously beneficial to Forests, Food Productions and Biodiversity. A 40% rise in CO2 has yielded less than a 1° degree rise in earth temperature. "The benefits of CO2 are so enormous, it would be Crazy to reduce it" Sun spots activity has a direct affect on Climate independent of the Sun 's temperature which does not change.

@@christianfaust5141 So, you want to stop burning coal, let's say, as a start? Wellllll..........
Here's what happens. As coal combustion in air is the source of most of the SO2 and black soot at higher altitude, ceasing coal use would remove much of these "pollutants" which will reduce the acidification of the seas and land, and reduce the darkening of ice which serve to melt ice and reduce darkening of land surfaces. These are good things, BUT............These two "pollutants" also provide a sort of aerosol parasol, the "aerosol masking effect" which keeps the global average surface temperature about 0.6 to 1C. cooler. So, if you stop burning coal, you reduce the long term heating of the biosphere and reduce the melt rate of ice and the acidification of land and water, but you will allow the near instantaneous spiking of global temperatures. If you don't survive the short term effects, the benefits of the long term effects are moot.
A fried of mine is a climate scientist was worried about the Pine Island and Thwaited glaciers starting in November 2022. He noticed that the iceberg blocking the PIG bay had started moving. He predicted a possible collapse, but was surprised by the extent of it over both glaciers within 3 days. But he was even more worried about the silence from not only the media but also the climate world. He started a group to discuss the Antarctic, and he invited me. The situation is worse than you talked about, since Deep Ocean Heat has caused the Swiss Cheesification of the ice barriers. We just came out of the Winter Melt Season, and the sea ice extent is off the charts, and faster than expected.
Funny, just when they lost the Antarctic they decided to allow the Middle East conflict to have their 12 box cutter moment.

I like the term Swiss Cheeseification… that is a very accurate description. Those glaciers will probably do a runaway into the sea and cause massive, impossible to imagine swift rises in the Ocean levels Worldwide. Ocean surges, floods never seen by Humans, death and destruction on an unimaginable scale. This scenario could be coming to Communities near you as soon as next Summer when the super El Niño Summer roles around to the Northern Hemisphere after hitting the Southern Hemisphere in the soon to come Southern Hemisphere Summer.

I've been following this channel for the past three years. I used to find them mildly irritating because most concerned the promise offered by this or that techno-fix. And my view is relatively simple: more techno-industrial 'progress' will not and can not hope to solve the problems created by techno-industrial 'progress'. What's needed is to manage global population and to begin to produce and consume far less of everything.
So I have been pleased to discern on this channel a greater focus on the very real dangers poses by climate change rather than what I regard as largely unrealistic aspirations to see us through the coming crises with more technology.
While people continue to believe that some 'clever people' will come up with a range of magic bullets, there will be far less pressure from below to adopt measures that might actually help.

Thanks for your support and suggestion. I will have a look at that.
Another possible "feedback loopy" scenario that could accelerate ice sheet loss is the potential for increased seismic activity due to the rapid reduction in the immense weight of the ice sheets as they calve into the ocean. Earthquakes would loosen the ice's grip on the bedrock and cause cracking, both of which will accelerate ice loss. This may be decades away and it is impossible to predict its extent.
The subsurface rock will rise with the reduction in ice burden. This will lift the ice sheets and make them more stable. A rare example of a negative feedback!

I told people many years back why they disliked Dr David Suzuki, an early speaker of truths on climate change was: “those who speak the inconvenient truths make others feel uncomfortable with their past and present decisions”
1:05 i was about 10 years old when i first saw a penguin shoot poop across the whole exhibit in thr zoo, covering several others with its runny waste.
I no longer liked penguins and 50 years later that still has not changed.
Unfortunately, it's likely already too late. The answers lie with the people. We elect our politicians to speak for us and our politicians know that there are no votes in a radical green agenda, so they tell us to keep flying off to Benidorm, keep having children, nothing needs to change and everything will be fine. That, unfortunately, wins elections.
While they fly off to Panama and the Bahamas to hide their money for the proverbial rainy day - which even they and especially their kids will not live to see ...
We're not that different to a locust plague, except we have music and dressing gowns, oh, and we are aware of our actions on our own future destruction but ignore it bec.... did you know that ahole desantis wears lifts in his shoes and even lied about his actual height???? Reeeeee....!

SO glad you called this out again. As awful as the events of the middle east and eastern Europe are, the potential catastrophe looming from the Antarctica thawing are even more sobering. We have unleashed a chain of events that are now humanly unstoppable. There is only one option left as we face the 6th Extinction. PREPARE, PREPARE, PREPARE Because we are not going to stop this happening.
> potential catastrophe
Ye, I think we've gone way beyond "potential" (in fact now inevitable) around 50 years ago. If it was true those decades ago that if we took decisive action then to prevent the worst possible outcome the statements that if we take decisive action today we can stop the worst from happening is at best tragicomical.
@@CABALlc1 Realistic and Pragmatic response my friend
We don't know this. As far as people and their lives go, the Antarctica is not known to be a human created risk, and we don't know that there is any risk at all yet. We really don't have enough information. But a war can kill tons of people really quickly. That's why doctors treat heart attacks first, and worry about all other health issues later. Because the later does nothing for the patient if they are dead.
This is why we have to focus on issues like war over theories about a continent we know very little about.

Dave is a climate hysteric. Getting rich scaring children. Evil!
It is so scary and we are so seemingly powerless. We've been raising our voices for years but the powers that be don't appear to care or just act annoyed or worse, hostile and aggressive. It's so frustrating.
Decades. 😢
I think even those you think are 'in power' are effectively powerless too. Nobody actually knows what can be practically done without causing massive upheaval and distress. This situation we've dug ourselves into is just too damn complicated. We're only able to very tentatively change little and effectively insignificant aspects of our lives at a time and there's often considerable resistance against even that.
@@UCCLdIk6R5ECGtaGm7oqO-TQ I agree with some of what you said, but we *do* know what can practically be done. The problem is the greed of the vested interests that are holding back the progress that diminishes their power and profits. The barriers are political, not scientific.
@@UCCLdIk6R5ECGtaGm7oqO-TQ No, that's not the case. It's not too complicated. We know exactly what to do. It's a political problem. To the OP's point, this means that we are not powerless. We can work to elect people who will do the right thing. In America this means defeating Republicans. The best thing any one person can do to help the climate is to vote the denialists out. When Democrats finally got a bit of power in America, we got the "Inflation Reduction Act", which is a huge climate bill that is causing a revolution in the way we use energy. That is what happens when you elect the right people.
Science has become so politicized that no one knows what to believe anymore.
What is so frustrating is that we are increasing the temperatures of the oceans not because we want to, but because human activity and the need to, say, heat our homes is throwing a stick in the spokes as far as slowing down carbon emissions. I am not a climate scientist, but I think we all have to realize that the 70% of the earth's freshwater that is currently ice in antarctica is sooner than we think going to become liquid water very, very soon and that is the straw that breaks the camel's back as far as I am concerned. Because this surely will mean that the AMOC becomes dead in its tracks and when that happens the earth becomes a whole new planet.
And where is your proof that humans are the cause of climate change? If you have this proof come and tell. As long as there have been humans on this planet, there have been preachers saying the sins of man cause bad weather, earthquakes, crops to fail etc. The common solution to repent is usually for some sort of offering to appease the Gods.
It's going to melt either way. And then it'll freeze again. All it takes is for a chunk of asteroid, or a big spew from a volcanic eruption, or even more likely, a radiant CME burst to wipe us all out within a years time.
When I was a child, I always wondered why people don't just invent better infrastructure and methods of dealing with natural disasters. Some do for earthquakes, but not enough for other disasters though like tornadoes and floods. At this point, just move somewhere else and invest in your bloodline's future. Use stone as a building material, or build your house underground in a hillside. You'll be fine and your family will own one valuable piece of property. At least for you, you'd have low insurance premiums
Yes. It is likely to enter in another ice age.
All the ice has melted before. It is nothing new for the planet. It would be new for humans.
A concern about AMOC stopping is that while it would mean Europe would not be getting the warmer equatorial water and become much colder, the equator would retain that warm water. This would increase the difference between the north and the equator which would likely lead to much more extreme weather patterns.
Love your work. Never stop please.

Where's the downside.
What's the downside.
I moved to south Brazil 3 yrs ago. What I have observed are the Low systems that used to tightly circle Anarctica, are now widening their paths. The lows are spinning off and effecting Australia and South America. Sending sub tropical cyclones up the coast of Argentina and Brazil. I expect cyclones to become a regular occurrence. Also there appears to be a river flowing over the Andes, from the west, and turning into flooding in Southern Brazil.
It’s been warm in your neighborhood lately.
Very worrying!
Hi from the very south of mainland Australia. We are observing those changes on this side of the globe. I agree with the climate scientist James Hanson in his predictions for catastrophic wind. Our building codes are very lax, we are in no way ready for what is about to come.
It's a weakened jet stream causing that by a reduced temperature differential between the pole and mid latitudes. The same has been happening in the northern hemisphere.
The Australian Cyclone forecast for this season is almost double the average of previous years.
Oh well. We'll still look to maximize short term profits for shareholders, doesn't anyone believe that'll change?

The inexorably rising Earth Energy Imbalance (EEI) (sustained by an irreversible total cumulation of greenhouse gases), subsumes all regional variations of land & ocean temperatures. The EEI fuels & exacerbates adverse & extreme consequences to our biosphere (eg warming, melting, flooding), on a pathway to severe degradation of, & shrinkage to, our habitat, presenting an existential threat to the survival of our species.

Yes, “Our oceans have absorbed more than 90% of the heat building up in our atmosphere”caused by anthropogenic global warming.
How could they? Nonsense.
@@tsaicioI don't know the amount, but it's obviously not nonsense, because the oceans interface with the atmosphere over a vast area and the laws of thermodynamics mean that both try to come to equilibrium. Imagine a completely enclosed fish tank half-full of water - pump the air in the top through a cooler and make it cold then let it sit - eventually the heat from the water moves into the air. Pump that air through a heater and let it sit and eventually the heat from the air moves into the water. That's just basic physics and why fridges work.
@@tsaicio Not nonsense. Liquid water has a much higher heat capacity than air. It can absorb much more energy than air for a given temperature change. Specifically, at sea level one cubic meter of water absorbs 4,184,000 Joules to produce a temperature change of one degree C. A cubic meter of air absorbs 840 Joules for the same temperature change. A factor of about 5 thousand times as much energy.
@@tsaicio My simple uneducated explanation. There are many more particles in the water vs the air. If you heat up your stove, the air will heat up almost instantly, but put a small pot of water on, that same airspace will be room temperature comfortable for a few minutes. Also given how deep the oceans are, the volume of the ocean vs the atmosphere is probably at least a 1:4 ratio.
I've yet to hear where the proof is of this anthropogenic global warming is. Some sort of scientific paper? Have you a link to this proof?
Question or topic suggestion - how does the current warming trends relate to other warming and cooling periods in the last 2000 yrs?
Up until the last 150 years the temperature has been remarkably stable for near 10000 years . Even though temperatures are rocketing away now it was slow at first because most excess heating had been absorbed and `buried `in the sea and you have to put a massive amount of heat to actually melt ice , once melted the water heats up far faster . That and buried heated water now resurfacing and the huge amount of GHG (effectively a blanket that like a blanket takes time for heat to reach a new equilibrium ) is causing a monumental temperature rise and more is baked in as were at least 30 years off equilibrium with what we have now ..and GHG`s are rising at there fastest ever rate even after decades of dire warnings .
It's not as warm as the Medieval Warm Period, Roman Warm period or Holocene Climate Optimum (Minoan Warm Period)
@@bubbabigmin I hope your not denying rapid catastrophic human activity induced warming now ?

He's a liar. Climate hysteric. Bad man!
In 1971 my college professor interrupted our electronics class to talk about global warming and how it is affecting the jet stream. If the jet stream path starts changing to extremes it will created extremes in weather. That's the first time I became aware of global warming, just by bringing up the subject to class rooms

Thanks Dave, I can’t un-see that penguin now.
As a suggestion for a further edition - the media tends to focus on average temperature change, however it’s the extremes which have the greatest impact. It would be useful to understand what modelling and empirical data says about the statistical spread of climate change.
I see that NZ has had a recent political lurch to the right. Will that mean a loosening of their environmental attitude? Possibly.
The ocean currents slowing down to a stall reminds me of an early outcome theory around the 1990s when it was said that the human living zones may become banded into fairly tight latitudes, with the extremes almost permanently covered in ice right down to northern Europe, with similar results in the southern hemisphere. As far as I remember, this didn't take into full account the rise in global temperature or the terms we used to use, the Earth's energy, or heat, budget. But what it meant was that Northern Europe, America, Asia, echoed in the southern hemisphere, would have incredibly severe cold winters and very short summers, while southern Europe and those latitudes either side of the equator would be the only liveable bands for the global population. It ain't pretty. We've moved away from that singular theory idea since, but it's influence will be felt in the mix.
With its population of about 5.2 million, NZ is 0.06% of the world's population, and it emits about 0.14% of global emissions. The majority of NZ's emissions are due to production of sufficient food to support about 100 million people - mostly in other countries. So if NZ was to blink out of existence and zero its emissions it would make no meaningful difference to the climate, but a lot of folk would miss out on their steak, lamb and cheese. The flavour of its government makes no difference to the big picture at all.
Already the situation was hopeless under the previous Labour government. We even got the honour of a telling off by the WEF no less (yes the WEF lol) for not even being on track to meet our very unambitious domestic target. Things now will get even worse. One of the parties in the coalition (Act) wants to scrap the entire framework that sets domestic targets and requires governments to come up with emission reduction plans. NZ has a 'clean green' reputation but the reality has always been different - 70% of rivers are heavily polluted with nitrate runoff and emissions have been sky high for a long time.
@@philip88154 NZ's emissions would ease if they were spread over the whole population served by the country's primary production. That would put the 'blame' for those emissions where they should lie (in countries that consume the produce), and ease the need to impose draconian emission controls within the country. While certainly there is no room for complacency, NZ should be more concerned with developing and implementing adaptations to the expected climate change and sea level rise than with major economy-wrecking emission cuts, IMHO.
@@nigelwilliams7920 Even if you measure the consumption based emissions (which excludes what we export), our emissions are still between 8-9t per capita CO2-e. They need to be 3t on average globally by 2030 to keep warming between 1.5-2 degrees. Responsibility for emissions should lie both with the country of production and consumption. There is a lot of research showing that there needs to be a shift away from meat and dairy consumption globally to meet targets. NZ as a major producer must do it's fair share, we are after all also a relatively wealthy country by global standards as well.
Why no mention of the geological (thermal impacts) input? To easy to directly measure?

Good piece. I wish you would mention the effect of ice falling into the ocean, assuming it is not floating and therefore not subject to buoyancy principles, will raise the ocean water level. So much of the focus is on melted water, but ice chucks do the same thing but in a more punctuated manner.
Why would you assume it’s not floating?
@@beezybeez4207 Because, if it is already floating in the ocean it will not change the effective displaced volume of liquid and raise the level of the ocean surface since it is already "floating" in the water. If it is above the water and then enters the water its volume immediately becomes subject to Archimedes Principle and adds to the total volume of water, raising sea levels.
@@beezybeez4207 The structure of Antarctica is such that a large part of it is above the water level and is not floating. The mountain ranges and other structures are supporting ice that will be capable of entering the water and raise sea levels without melting.

you are right because if the ice goes then all that fresh water will dilute the salt content and slow down the movement of heat around the world and can have an effect on the weather.
So what can you or anyone else do to stop it, anymore than they can stop the Sun rising in the morning?
It's not just that, if the current slows down so do the tiny nutrients that support the food chain of life in the oceans.
There is already a dying off happening in spots around the world including small pockets where oxygen is missing, poisonous alge will become more frequent due to the warmth of the oceans.
Those at the top of the food chain like Sharks, whales, killer whales, dolphins have been observed at different points of making a shift or trying to adjust to survive. It's not happening everywhere, but enough that we should take notice, these are the seas 'canaries in the mine'
I believe sometime in the future, we will need to make a tough decision to leave the ocean alone for a few seasons so it can adjust and replenish itself as it will not be able to adjust, support humans and sealife while it is depleted.
They don't call me Cassandra for nothing... 🙄
More worrisome to me is the suggestion that modeling the emerging dynamics will not provide useful forecast (see “turbulence”). Climatologists like Jason Box and others discuss that a number of dynamics are not accounted for in current models, which lack resolution and math to include them in the models. Other techniques lack the data to approximate modeling. Beyond this, though is an implication the process can become chaotic, that is, they can’t run them too far into the future and expect them to remain accurate. If we can’t model 30 years or something along those lines, into the future, we’re in a very different world indeed.
Long term weather modeling is about as reliable as economic forecasts.

Yes, the sixty year climate cycle.
I wonder why we never hear about the massive amounts of emissions that comes from jet air traffic??? If you look up the massive amounts of fuel each flight consumes it will give you something to have a think about
Or think about each of the worlds many billionaires' personal carbon emissions as they travel in superyachts and private yets ... and rockets ...
Just read that aviation contributes 3% of warming. Not that much, but every little bit hurts. I think that ground transportation is more significant, due to the greater number of vehicles.
Maybe because air traffic doesn't contribute much CO2. From a quick internet search it's something like 2.4% (2018) of all emissions. The number is increasing due to the number of flights increasing. Aircraft engines are some of the most efficient engines out there, and they continue to improve. Many other industries produce substantially more CO2.
I believe that the amount of emissions from flyers is huge as measured from the that individual, well beyond any other form of travel. If everyone flew, the total numbers would be astronomical. If everyone stopped it might make a small difference. Huge fuel cost increases might make a fractional dent as well. Think all the air forces on the planet are going to stop training? How about sports teams hurrying to their next arena? Do you support a team? Perhaps the reporters asking questions after games could ask about the teams "carbon fart print".
@@danielfaben5838 The OP didn't say which is worse 'per person', just that flying was a big emitter, which in comparison to other sources it's not.
Or another way, if the world stops flying tomorrow we would only be stopping 2.4%/yr of Co2 from entering the atmosphere.
Stop eating meat, or everyone starts carpooling, taking a bus or train, or find a better form of concrete for construction, or stop using bunker fuel and such for cargo ships or find/stop the (mostly methane) leaks from gas production, or... any single one of those would stop (some significantly) more Co2 from entering the atmosphere a year.
Back to transportation, single occupancy driving Vs. long haul flying... flying is better with respect to Co2. Go to shorter flights then it driving can be better. Can't beat bus or train.
People speak of this for decades, but we don't seem capable to stop or even slow the problem.
The people making the money causing it have the geopolitical power to keep doing it.

12:20 That is a vast underestimation. We saw an immediate impact on oceanic temperatures when sulfur emissions were cut in 2020. Atmospheric aerosols have been concealing climate change much more than we think. It’s probable aerosols will in fact be necessary to prevent climate doom.
In the early 70's when I was completing my mechanical engineering degree I kept my interest in the geology etc alive by attend guest lectures. A guest speaker doing research on CO2 emissions from the industrial revolution onward was trying to determine where all the CO2 went since if it stayed in the atmosphere the the percentage of this gas would have been higher. I think today we have a better handle on where it went and is going. Best regards.

Icebergs melting does not raise the water level, ice is 2/3rds the density of water, that's the reason it floats. Ice SHELFS breaking off the Glaciers and becoming Icebergs does.
And quickly too, just as adding ice cubes to a glass raises the level of water even before the icee melts.
Sea levels will begin to rise as soon as the Thwaites glacier breaks away.
I was hoping you would discuss the impact of the active volcanoes and heat plume underneath the west Antarctic ice sheet. Almost everyone is ignoring that. The same is true for the heat plume under the Greenland ice sheet.

Thanks Dave just another reminder that everyone must stop burning stuff now! Whilst politicians mince around everyone that can afford to make mitigation measures should unfortunately that’s rarely the case! 😟
😂🤣😂🤣😂🤣
China's building a coal plant every week.
Burning things which are primarily composed of fossil carbon. Go ahead and burn ammonia if it's manufactured from atmospheric nitrogen, water, and non-fossil carbon sourced energy.
Were not ready to stop burning stuff just yet. To do so would result in famines, social chaos, poverty, etc.
@@simsong1188 And if we keep burning fossil fuels, it will result in famines, social chaos, poverty, war, mass migration, human extinction. So what's YOUR answer?
May the Anthropocene (Pyrocene (?)) epoch make the Permian-Triassic extinction event seem like a minor footnote in the pages of Earths history. Seems more and more likely, scenario SSP5-8.5 of the IPCC assessment may become a reality. If it does, enjoy what you can, while you still can; pity the next 3 to 5 generations to come.

You are very similar in nature to a very dear friend and past work colleague of mine called Peter. He’s from the UK. This current look at the southern ocean and Antarctica is extremely worrying and serious stuff. !! I agree. For our NZ scientists to do what they have, signals a new alarm to the world.

@@debbiesroommate why wouldn't you?
Out of personal experience I can say that the main problem in communicating what is happening is that it is a slow process for personal human understanding and acceptance.
Apart from that it is a complex system with a large number of ‘parameters’ involved.
Very few people can or will understand what is happening and react with incidental remarks that lack satellite view and time perspective.
Thank you for another very insightful video. It seems like no amount of sensible data will project us into action, unless our daily lives get drastically affected. Which will happen (not?) soon enough...
Notice the ice core data he supplied only goes back 1000 years. The Vostok ice core data goes back at least 450,000 years. Why did he exclude this important data?
😮 Glutton for punishment here.
Why do folks always present heating as negative?
Because they have no idea that we are currently in an ice age? (In an interglacial warm period.)
@@MsBiggles51 They are also misled into assuming that warming is more dangerous then cold.
Population in 1980 4 bilion and now its 8 billion all these problems stem from that but it is totally ignored.
And I think much of that rise comes as a consequence of the abundant energy and usefullness of fossil fuels. Whoops.
Malthusians have been using the same theory for 150 years that resources will outstrip supply, but humans keep keep proving them wrong. What may do it, is transitioning to alternatives fuels that rely on rare minerals.
You really need to start this when fertiliser came about from ww2, without it these people would not exist and the use of oil, energy we never had before, from that time also. People are not the cause but the result. If we found out how to refine oil 2000 years ago this population bump would have happened then.

Just saw whales with their babies in Hervey Bay in Queensland resting before their long trip to Antarctica to feed up. I remembered your last story about warming waters in Antarctica which will effect their feeding as krill will be effected by the warming waters. Another consequence of global warming. Keep up your great work.
"Overall, the Antarctic ice shelf area has grown by 5305 km² since 2009, with 18 ice shelves retreating and 16 larger shelves growing in area. Our observations show that Antarctic ice shelves gained 661 Gt of ice mass over the past decade." (Andreasen et al, 2023). It is from a paper entitled "Change in Antarctic Ice Shelf Area from 2009 to 2019". They use MODIS (Moderate Resolution Imaging Spectroradiometer) satellite data to measure the change in ice shelf calving front position and area on 34 ice shelves in Antarctica from 2009 to 2019. Also, as the mass gain (661Gt) was given, you could calculate the volume of the ice gained using the formula: Volume = Mass ÷ Density (assume Density of glacier ice 0.9167 Gt/km³). This would give you (well not you obviously) an Ice Gain Volume ≈721km³. That's how much extra of the lovely white stuff there is around Antarctica. Imagine standing in the centre of this extra ice. It would stretch beyond the horizon in all directions and would be 45 storeys high.
Thank you for having this info to hand. I had read that researchers were saying what you have written but googling for it to remind it is a nightmare when so many scientists and researchers are having their work hidden from us!
But but but this cant be true! 😮Exactly Now when third world is rising we must ban oil. Not only the viruses are smart atracking only after 20h climate is also.
That is only the "ice shelf". Using their methodology, Antartica ice shelves have gained 661Gt of mass. But, other studies show that Antartica as a whole has lost approximately 1500Gt over the same time frame. Also, if you read more than the abstract of that paper you would see where ice shelves are losing area (west and the peninsula) and growing area (east): "This study has generated a comprehensive dataset of change in ice shelf area on 34 Antarctica ice shelves over the last decade. Overall, ice shelves on the Antarctic Peninsula and West Antarctica lost areas of 6693 km2 and 5563 km2, respectively, while East Antarctic ice shelves gained 3532 km2 of ice, and the large ice shelves of Ross, Ronne, and Filchner grew by 14 028 km2 (total)."
@markvalery8632 So not "out of control" then as per the video. Antarctic ice sheet mass loss is about 90 Gt/yr (Otosaka et al, 2023). It's total mass is 24,380,000 Gt (24380000000000000 tons), so it loses less than 0.0004% of its mass annually, which I think you could reasonably round down to zero. It contributes 0.36mm to sea-level rise per year (that's essentially nothing as well). At the current rate it will take well over ¼ million years to melt, but we are due for two more glacial periods in that time. That ice is here to stay.
@@OldScientist Yah, because all physics is linear and there are no feedback loops involved. I understand now.
Is the sky 🐥 falling .
Do you have any input on how to slow down the stop of world war 3 in the Middle East so that we can worry about the sky falling some more.
Great video Dave. It's clear that you put in a lot of hard work every week. These latest data are, as you said, really worrying. More so because all of the worst greenhouse gas offenders seem to be more and more in thrall to the fossil fuel industry. I'm a grandfather and I've been really worried for my grandchildren future. With the reports coming out now I'm starting to worry about my children's future. Things do seem to be getting more dire much more quickly than even the most ardent Climate Scientists thought they would.
We need action now, not next year, in five years, or over the next decade. The fossil fuel industries will surely make certain that doesn't happen by plowing billions into buying off the right people! Yikes!!!
Getting rich from scaring children. What a jerk. No climate emergency.
I think we are a bit too late. CO2 lifespan guarantees many decades of future warming, and we are only now just seeing the effects of what we did in the 1970’s. Imagine when the impact of the 2000-2020’s economic revolution arrive. I suggest you stop worrying and accept the inevitable. Prepare, or don’t, it doesn’t really matter because we can’t live on the moon or Mars, no matter what Elon wishes. Besides, if trump gets elected you can expect the decapitation of many of the world’s government functions. That is when the END party will really begin. Enjoy.
Thanks for the news? ;-) "...leaders pause for thought." Presupposes a level of gravitas in our leaders that does not appear to be all that common.
Thank you for your great work.
He's a liar.
I had the urge to spend two years in the Antarctic when I was younger. When I found it was indeed possible, it became irresistible.
It was worth going; but not so much so that I've ever wished myself back.
In fairness, where I was based the lowest temperature was around -40C, not the -80 that some parts of Antarctica does indeed get.
Also where we were, we only got -40 in still air: when the wind blew it got warmer on the thermometer even if it felt nastier. Again that may not be so elsewhere.
From the sound of this Pod one would imagine it was warm Thanks for your temp readings
Do you think a rise in temperature of 0.03C will make any difference?
PS: I should add that our base, Halley Bay (UK), was on floating shelf ice. That's ice that has fallen as snow in the past onto the continent, but has slowly flowed off the edge at glacial speed and is now floating on the sea below. That's different from "sea ice" which is ice formed in the surface of the sea when the air temperature is below -2C (in the dark) or below some colder temperature when the sun is shining (because the sun warms the top layer of the sea). As you approach the area by ship, it breaks through the relatively thin sea ice to approach the cliffs made of what is essentially compressed snow, maybe 60 meters high, with another 150 to 200 under the water holding them up. Nobody has ice breakers that can cut through that!!
They make the famous "White Cliffs of Dover" look dull in comparison :)
It's that proximity to sea water that kept our base warmer than the inland bases (especially the US base at the South Pole) and the Russian base (which is at the point furthest from the sea: the so called "pole of inaccessibility"). It's the Russian winter-overing staff who get the lowest temperatures on the planet to live in, as the temperature gets steadily colder the further away from the sea you get.
At Halley, and at bases on the rocky coastline of West Antarctica, the nearby presence of the sea is what makes the wind be warmer than still air.
Were we worked that we lived in what was essentially a tethered iceberg? That the sea was not only a walking distance from us horizontally but also some 200 metres below?
No: because there is plenty of warning when floating land ice breaks off. That's because we (not me personally, but some people at the British Antarctica Survey) understood the dynamics well enough. That may change if conditions continue to accelerate as religiously as they are at present, making bases on floating ice shelf
Eventually any it will "lob off" and become an iceberg. Our base has since indeed lobbed off, so there was an iceberg around at some time with my bed in it, and the rest of our base.
The next base at Halley has also been abandoned.
Because they got fed up of having to build new bases every few years, the current base consists entirely of structures on skids (like giant sleds) that can be towed towards the continent as often as needed.
That base has now had to be moved at least once, so at least three floating ice locations have been abandoned at Halley since I left in 1983.
@@Sjb-on5xt @Sjb-on5xt please refer to my recent reply for more background info.
of course if was a one-off rise, no a rise of a few hundredths of a degree would make no almost difference at all locally. However with a 2C rise in planetary average temperature being considered dangerous by the experts, even 0.03C is 1.5% of the danger level, if repeated year on year for less than a century and over the whole planet.
So yes it's enough to make me worry not for myself (already in my retirement) but for the world my grandchildren and great grandchildren will live in (assuming my daughters choose to have children).
The problem, as Dave has explained, is that this is an upward trend discovered by comparing data collected from different years. 0.03C/year is another 0.3deg by 2033, and 0.8deg by 2050.
However it's worse than that. This looks like the start of an accelerating change. If a car is rolling towards you at walking pace that's not a worry, but if it was stationary just now and has just started moving that might make you think it's worth getting out of the way; or better to make it stop.
@@Sjb-on5xt I think factories spewing out CO2 in 1200rds caused the Little Ice Age that lasted until 1850

When the ice is gone there is probably a sign sitting underneath the ice that says:

Welcome to Waterworld
I wonder if some of the previous mass extinction events in the ocean have occurred due to sudden shifts in these relatively stable marine chemical processes such as freshening/stratification.
I'm imagining that, unless the public steps up and asserts their influence, the powerful few will continue to exert their influence to instead increase pollutants that will reduce the effects of solar activity on the temperature so that they may continue on using carbon based fuels.
Unfortunately the oil,gas and coal industries have government between a rock and a hard place. The ship has sailed, I don’t think it’s possible to effectively change course at this late date . I am not optimistic about the global future.
There was much less Antarctic ice in 68. I wish people would stop lying to us on the public dime. It is nauseating.

@@leftcoaster67certainly very few TIs.
Antarctica averages more than 40 degrees below zero. So a couple of degrees of warming cannot melt it... because physics.
Antarctica gains ice from snowfall and loses ice by iceberg calving, sublimation, and submarine melting. Those processes are in nearly perfect balance. The net ice flux is so close to zero that scientists don't know whether it is positive or negative. Some studies report that it is losing ice, others report that it is gaining ice, and others report that the trend is statistically indistinguishable from zero.
However, there's one thing that all the studies agree on: the rate of Antarctic ice mass change (whether positive or negative) is so slow that it has a negligible effect on global sea-level trends: almost certainly less than 2 inches of global sea-level change per...
...did you think I was going to say "per year?" Or "per decade?"
Nope! It's *_per century._*
The best & most comprehensive study of Antarctica ice mass fluxes to date is this one, by a NASA team:
Zwally _et al_ (2021). Mass balance of the Antarctic ice sheet 1992-2016: Reconciling results from GRACE gravimetry with ICESat, ERS1/2 and Envisat altimetry. _Journal of Glaciology,_ 67(263), 533-559. doi:10.1017/jog.2021.8
They reported that the ice mass trend is −12 ±64 Gt/yr. That's ≅ zero. 12 Gt/yr is the equivalent of 0.1 inch of sea-level change per century, and the fact that the confidence interval is larger than the central value means that don't know whether it's positive or negative.
You'll confuse them with actual science if you keep that up!

Issue with denialism is that there always one more excuse from endless bag of excuses why not doing what is needed and necessary. it is easier to spend 2.2 trillion USD on military worldwide so we could blow our selves to smithereens easier, than actually invest part of that money to technology that will transfer our emission to be more nature friendly...
Why pay for an army if the governments can make the entire world energy poor and stop all that nasty "being fed" and "not dying from climate disasters" and "food production increasing so fast land use is falling" and "life expectancy continues to go up" and "urban populations decline with greater wealth"
Instead we will make everyone poor. Only billionaires who pay the proper indulgences should be allowed to live their life as they choose.
