[@kimweaver1252]

@@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.

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.

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.

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.

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.

[@nigelwilliams7920]

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.

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.

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.

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 .

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.

[@danielfaben5838]

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?

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.

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.

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.

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.

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.

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.

[@OldScientist]

"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.

[@markvalery8632]

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)."

[@OldScientist]

@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.

[@markvalery8632]

@@OldScientist Yah, because all physics is linear and there are no feedback loops involved. I understand now.

[@OldScientist]

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.

"We are going to geo-engineer ourselves out of this pickle" and "We are in a technology race to try and fix the issue". What exactly gives you confidence that's even true? Are you young?

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...

[@paulsnow]

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.
