It's at the heart of Antarctica and on the verge of collapse.

Man-made climate change is warming the planet's atmosphere and oceans, and the effects are being felt the most at the poles. In Antarctica, home to the largest chunk of ice on earth, ice shelves and glaciers are beginning to collapse, and one in particular could spell disaster. The Thwaites Glacier, in West Antarctica, has retreated more than 14 kilometers in the last two decades as warm ocean water undermines it. The glacier is situated on a downward slope that falls deep into the center of Antarctica. It's why scientists are racing to find out how close it is to total collapse - and what that would mean for future sea levels.

A very bleak & cereal outlook for the world to take notice of now. Heeding the warnings of climatologists have always fallen short on deaf ears within the big political engines that dictate our societies!.. Generation’s to come will only have unthinkable challenges before them that past generations left behind . Praying the world takes notice & curbs the already diminishing timeline that lays before us all globally...

The Antarctica ice has been melting for thousands of years and one of the reasons we are no longer stuck in the Ice age.

How about we build a massive wall to go all the way around Antarctica and power it like a freezer using renewable energy, in order to stop it from melting any further. Because even if the emissions stopped tomorrow the ice sheets will still melt for quite sometime before it can get colder again?

@George Lane I strongly agree with u 😉 but if we stop polluting then it will still melt for several years and some carbon is being released from those melted ice sheets!? I think we need to find away to do both, because the amount of carbon stored in those ice sheets is massive amounts that could set off an irreversable change, one in which life on Earth can not adapt to quick enough and when some of those important plants or animals go extinct, it will set off like dominoes and effect the biodiversity that is part of the circle of life will equally become extinct! 😞 for example the bees are being effected by pestisides and pollution and the amount of pollating they do helps humans with at least 60% of our food source. Humans need to stop damaging the planet, because we only live on 1 planet and if we dont look after it and protect all living things then humans will be equally become exinct 🤔

a bigger problem than higher water levels in several centuries is the acidification of the ocean. which could actually create massive deserts.

It's already underway, we won't be able to stop it or slow it down. We already know how the mask thing has gone, some wear it, some don't. However, by the time it melts, we will probably have a other means of survival. Whether it's here or on a different planet.

OK. I'm just going to say this. If the Thwaites Glacier is primarily below sea level, then the only potion that will raise sea levels is going to be that which is above sea level. Since water is actually denser than ice, the ice melting in the below sea level portions of the glacier will actually have the effect of LOWERING the sea level. I guess the total net gain/loss in sea level will depend on how much of the glacier is above sea level, and how much the water will expand due to temperature increase.

The melting is a part of a natural Earth cycle that is bigger than us humans. We still do not understand ecology as well as we would like. Earth heats, cools, heats. That's the cycle, and it is, if I recall properly, ~ 25,000 years long, but there are other smaller and other larger cycles.

an awful lot of these sort of videos forget to mention that, in general, everything changes. So since change has been a constant for the known universe, all these videos do is confirm that yes... things in the future will not look the way they do today. A lot of this anxiety is down to us having the tools to measure and monitor this change - whereas in the past human anxiety was likely down to a poorer understanding of how the world worked - and we compensated with myths and stories to soothe ourselves...

Everyone: Starbucks REEEEE Me: *gets intense anxiety about 3rd world countries economies failing (like with coffee) due to climate change leading to war, cartell violence and hunger driving people in mass migrations out of their countries which will lead to a far right pushback in the first world resulting in stronger nationalism and science denial further exacerbating a problem only preventable by international cooperation and trust in science*

“The complete collapse of Thwaites will take Centuries.” Ugh...no. This is runaway climate change we're talking about. It will collapse way sooner. Global warming is affected by multiple reinforcing feedback loops - we're talking about exponential growth, nothing linear. Humans will not be able to adapt to such dramatic changes of climate. We're animals and require habitat. Not just sea level rise either - but more intense and frequent storms, drought, famine, water shortages, heat waves, outbreaks, and increased global temperature. We don't have much time left. Enjoy your life and love while you can.

I live in Connecticut on the Long Island Sound. My neighbor from Taiwan, just the other day, had a friend who lives by a river in China, that is normally of a yellow color this means it's full of nutrients causing the crops to grow bountiful. Of late the River's water has become clear and the crops are not growing so well. I told her maybe the river is now getting enormous melt off from a glacier upstream. She also mentioned the sea water was not as salty.

- If I take a kiddie pool and put four inches of liquid H2o in it and four fifty lb bags of ice which raises the liquid water to six inches , then let it all melt , and measure the water level it will always be the same . Six inches. Explain that please. If there is not a sensible answer that i can duplicate I will take that as a you don't have a clue.. Secondly. I am 53 yrs old and I have not seen the ocean rise even an inch respective to Atlantic City Beach which I visit every summerin that time. Please explain this too..Thank You..

In my opinion, it's the companies that dump chemicals, raw sewage and garbage into the water ways for example, that should be making the changes and forced to make the changes. But so many humans are expecting someone else to fix a problem that they themselves are creating....Stop purchasing disposable items, stop purchasing stain and fire resistant items, reuse, refurbish, etc....This is a money game and the big polluters do not care; even about their own family. And don't get my started on the geoengineering chemicals that are being sprayed into our air...To me, these are all the causes of our environmental collapse.
