Doesn't fit with their pre planned "Record fires because of drought" scam narrative. (there isn't record fires, they've just expanded the area they monitor into the Arctic, and they are more stinky because they are volcanic dike insertion into tarsands and peat initiated. The only thing you need to fear is those who seek to scare you, and by that control you. There is nothing unusual about what Jason is talking about. There is not an IceSheet on the area Jason is talking about anymore. This Ocean heating and CO2 degassing is driven by 59 and 210 year Earth-moon-sun orbital parameters that cause the equatorial circumference to expand by 10 kilometers while the Earth's polar radius decreases by 1.5km. And back again. This is now known to be the prime driver of plate tectonics, and as the moons orbit tilts more or less steeply relative to the plane of the solar system, also draws the weather belts Further towards the poles. This causes peaks in volcanism, particularly the seafloor spreading vulcanisim similar to recently observed occuring in Iceland and under the Greenland and Antarctic Icesheets. And in the deep Arctic and Southern Oceans. The atmospheric gas record from Ice Cores has proven worthless, as the volitility is on far shorter timescales than the 5000 to 9000 years that it takes to seal gas into an ice sheet. Leaf stomata proxies, and speleotherm, and sediment cores have taught us that there has been warm and cold oscillation on around a 230 year cycle for the last few thousand years, we are past the hot peak, we are not as high in greenhouse gases or temperature now as the medieval warm period. And we now know that subglacial volcanism has melted Greenland and Antarctica Ice sheets back past where they are today, and then the glaciers have advanced again fed by the enhanced evaporation from volcanically heated polar seas, many times in the holocene, the last 20000 years. Tell Jason to catch up with the science.

I can never work out how people can claim that nothing has changed, reporting such things as the high tide mark on a pier being the same now as it was when their grandfather was a boy - as if a man in his 70's actually took any notice at all of tide marks when he was a child. But the number of people who then thread such comments with equally ridiculous claims that temperatures, or rainfall, or hurricane seasons, etc are all the same as they were 50, 60, 70 years ago - when the science and meteorological records proves they are far from the same - it's just astonishing. I took have worked and spent much of my leisure time outdoors all my life, and even though I live in one of the least affected regions of the world - it is very clear to me that the climate has greatly changed. Nothing is the same. Indeed, it puzzles me that scientists claim the atmosphere has only warmed by 1.5 degrees. Comparing temperatures of my childhood home past and present, the summer highs have increased by 12-13 degrees Celsius. Temperatures there would be intolerable for me now, and like the fast disappearing insect life, I have moved further and further north. The anti-climate change comments have lessened a little in the year since you wrote your comment. But I don't like the way that the remaining closed-minded deniers now label environmental concern as 'woke.' That goes to show how increasingly desperate they are to put everything they want to blame their personal failings on in one big basket. The most recent videos on climate change are now very troubling, giving us less and less time it seems. Indeed, the world feels like it's going mad right now, and tensions here in the UK are breaking. I'm only glad my only child didn't want to bring children into this world. At least he has enjoyed his childhood and youth in his own way. And I can say that I saw Nature in my own country when it was still pretty good. The decline now is just awful. The disappearing insects is having a very severe effect this year, birds vanishing too, and very few amphibians and reptiles to be seen. I think this 6th extinction is going to happen quite fast, in comparison to the previous 5.

Thank you Mr. Box for this very clear warning. I hope the right people see/hear about it! The part that should worry them, (us too) is the data that is NOT included in your ice sheet models. Depending on just what the effects of that data are on the ice sheets, our entire calculation of how fast the ice sheets will melt could be seriously wrong. The difference between millimeters of sea level rise per year, and centimeters of sea level rise per year, may not sound like a big difference, but it compounds year over year. I really hope I'm wrong about the melting speeding up, but that's the conclusion I come to from the type of data not in the models currently being used. This is important, because what we don't know is coming, we can't plan for and that will hit us like a sledgehammer in coming decades.

[@Calligraphybooster]

No, I think you are spot-on. The models predicting ice sheet melt are more like setting a timer next to an ice cube on a plate, discounting a myriad of effects that hasten the process taking place in nature, most of which will probably take us by surprise.

[@tedg1278]

Another factor that I believe is not properly accounted for regarding Greenland is the topography of the bedrock. Greenland is like a bowl with a huge ring of mountains and a central area below current sea level. A small rise in sea level is all that is required to lead to destabilization of the center of the ice sheet.

[@Calligraphybooster]

@@tedg1278 Ah yes. That seems to make sense. But it may be compensated (although I do not know at what speed this process takes place) by the bedrock rising, as the pressure of the ice on top of it is reduced due to melt.

The model presented at 5:14 triggers a memory of Colorado Front Range weather called "terrain-anchored convective events." Could that be analogous to what's happening in Greenland? Do the mountains inland from US West Coast create a similar pattern? When thinking about our atmosphere and patterns of vertical and horizontal circulation I think it important to realize how using vertical exaggeration in visual representations can give us a distorted mental image and basic misunderstanding of the process. The first feature of the troposphere that we should be aware of is it's incredible shallowness. Rapids, and standing waves. Like the Chinook 70mph stiff breezes that frequent Boulder, and those magnificent lee-clouds.

[@tikaanipippin]

Ice and water generally equilibrate at 0C under normal atmospheric conditons from the definition of the freezing point of water. If it loses heat, it freezes, if it gains heat it melts. So it depends on the environment. If energy is input, melting, e.g. if the sun shines on the melt pools, or air temperature is above zero, but if the melted ice water passes over subzero ice, it can freeze, or if there is wind chill.

Swiss Cheesification of ice. Faster than expected. Quite the strong message about stopping fossil fuels, and maybe using the only carbon capture technique we have today that works?

It initially was accepted in early 2018 before it was blocked by the fossil fuel lobby. Surprisingly no climate group supported this idea. Greta and her group rejected it at SMILE in Lausanne. But 2 weeks ago one member of FFF Sweden expressed support, and so I wrote another letter. The school hasn't answereed but the local OECD is interested. Maybe someone might give a call to EPAC Bulle and express support?

[@OldScientist]

"Greenland ice sheet mass balance from 1840 through next week." (Mankoff et al., 2021). If you examine Fig.2 on page 5, you will see there would be no correlation with the exponential increase in the concentration of carbon dioxide (280ppm to 420ppm) and the change in the annual Mass Balance Sum shown in the paper. Indeed there have been periods of increasing mass of the Greenland ice cap in the 1940's, 70's, 80's and 90's. (Remember CO2 was rising all the time.) The Greenland ice sheet is thought to contribute 0.7mm/yr to sea-level rise, so 54mm by 2100 (just over 2 inches). That sounds small because it is small. Also an accounting error. More recently Greenland Total Ice Mass Balance rate of loss reached its maximum in 2012 but the trend rate of loss has been diminishing ever since. That's while we've added 500 million tonnes of CO2 to the atmosphere (14% of total human emissions). The average annual loss is 0.005% of the total mass (around 3 million gigatonnes). That's neglible. Come back in 20,000 years.

A tipping point will be reached. The only problem is, it's devilishly difficult to predict when that will be. It's too bad that weather data from the 1880's to the 1960's is so unreliable otherwise the climatology community would have a larger data set to work with, instead of the very small data set used in all current modeling. Ice core sampling offers some hope but is still in a learning curve. Hopefully one day, this will be a thoroughly understood science that can be applied to modeling of when the tipping point will arrive.

[@jimmoses6617]

There is no scientific evidence for the concept of a "tipping point" in earth's climate history. The 1930s was the hottest decade in the U.S. and in areas where temperature data was available. The earth cooled from 1930s to the late 1970s, and every single major newspaper and scientific journals published articles about the "coming ice age". They were using the raw temperature data to come to this conclusion. Also, the medieval warm period was quite warm relative to today...when warm-weather grapes were able to be grown in Britain so successfully that the French put tariffs on red wines. Keep in mind that fear/alarmism is what sells, so that's what is being sold. Modeling is also nothing more than another format to present one's hypothesis. There is nothing inherent to a model that allows it to predict the future, though so many people have been manipulated into believing there is.

As far as I know Greenland is actually and archipelago of islands, there is ocean underneath much of the center. That should be where the melt water is going. Since it is sea water, a lot of fresh water pouring into it would lower it's salinity, making it easier to freeze in the short term. What the long term effect would be is more difficult to figure out.

[@jimmoses6617]

Some of the massive amount of snow that falls most of the year on Greenland melts in the summer, yes. Then, trillions of tons of snow fall on Greenland throughout most of the year. The "ice/snow net mass balance" of Greenland (what falls in a year minus what melts each year) is such that it is losing about 1/20,000th of its ice/snow total mass each year. This makes sense as we are entering an interglacial period, one of several over the past 500,000 years. At the current rate Greenland would be ice-free in 20,000 years or so.

Dr. Jason Box is the gold standard among climate scientists!

[@rosemariebredahl9519]

Are any of these frequencies "popping" cavitation-bubble(ish) structures, and, if so, what's being learned about that energy release contributing , with other self-feeding factors, toward accelerating the rate of climate-crisis changes?

As a snowbank melts the top becomes darker. The ice melts and particles settle on the surface as it melts. A glacier that has been growing for centuries contains dark matter as well. Are glaciers becoming darker as they melt because of this?

[@tikaanipippin]

Oh my God. Dark Matter at the poles? Don't tell the cosmologists!

@@guesswho6038 It's called cosmological voyeurism - the bigger and better their equipment gets the more exited they get when the images focus on ever smaller areas of space - and in unison they scream: "I'm coming, I'm coming, Oh, My God, It's bigger than I ever imagined it could be, give me more, again, I never felt it could be like that, don't stop, I don't believe it!", and with that science turns to Scientology, and they all become believers, and somehow Science becomes irrelevant in their religious fervour.

What do you think happened 11,750ish years ago, the great cataclysm..

[@Calligraphybooster]

This is a process unleashed by changing circumstances previously totally unforeseen, right? Peter Wadhams didn’t mention it yet in het ‘A farewell to Ice’ as far as I remember. We also spike, we learn more then ever at ever greater speed, and then all this knowledge, down to the ability to read and write get washed off the earth. Thanks for briefing us anyway, very clear presentation.

I notice forest fires in the northern boreal forest have caused a low elevation soot permeation of the northern hemisphere air mass, leading to a cooler than normal summer this year I guess because of low sunlight penetration. This may continue to act as a negative feedback loop as the northern boreal forest burns. Is this included in the models?

[@brettmoore3194]

Could you use a different term besides gravity wave....? Bouyancy wave maybe or rarefaction, trough and peak of a transverse wind current🎉

[@wlhgmk]

Could there be another phenomenon at play here. The latent heat of water between gas and liquid is 6 times the latent heat between solid and liquid (540cal/gram vs 80cal/gram). This means that if water condenses out of the atmosphere on to the ice, it releases enough heat to melt, say, 5 times as much snow or ice (some of the heat will be used for sensible heat, to raise the ice to the melting point). Another phenomenon might come into play here. When the wind reaches the top of the ice sheet at about 3000m and starts down the other side it heats by compression. A body of air flowing down from the peak to the sea would warm up by about 30degreesC. Of course it would likely release some of this heat to the ice, melting even more ice. (a neat description of a foen wind on an ice sheet is found in the novel, Plains of Passage by Jean Auel at about chapter 40 or so. It is a novel but Jean did her homework)

Are you saying that my 100 watt freezer is no match for my 3kw kettle?

[@bruceclark4754]

Professor Box is a good speaker and obviously a much respected scientist, but as a layman , i found this difficult to follow. Would it be possible to have a short simplified overview, emphasising the implications. Just a suggestion😊

[@zonta71]

Thank you for the academic presentation. Question that comes to mind is what are the effects of this heat in other places? Is their a cooling in other tropical regions? Or other regions that is below temp delta averages? I ask this because I was in Namibia a number of times of the last 10years and about 5years ago to present I experienced freezing weather where half filled buckets were frozenband stayed for over 40hears. We need a better coordinated research with politics expounged from the health check of our world

I would like a definition of "gravity wave" since that term is new to me in this context and can't be confused with that in cosmology.

[@dyingfromthelying]

Yeah... I wonder how long we can drag this thing out?

[@denispontbriand]

Thanks for your public involvement. The general public is unaware of magnitude of present state of affair concerning the climate change. Our psychology is so wired that we deny or avoid listening to bad news.

[@tikaanipippin]

Whereas @ 1:04 "Laser-focussed" sounds sharp and precise, @ 2:37 " 2/3rds-of-a-foot" and @ 2:45 "half-a-foot" seem particularly fuzzy, as most of the world understands millimetres as a measure of short depths or lengths. Once you begin using one metric, please stick to it. We have already absorbed that 200mm fell on Greenland and that one foot = 304mm, and we can mentally work out that 200/304 = ~2/3rds of a foot.

[@veronicasvevabrugnetti]

thank you

So if so much rain would create faster sink and reduce gravity lower presure attract more from higher presure so if beyond threshold it is unstoppable fir a long time until exhausted large water shifting
