People are well aware that global warming has been responsible for causing an increase in sea levels by adopting two processes.

Melting lakes on ice shelves can widen cracks within them - new research shows how these lakes change across the world’s largest sheet.

That we are causing directly. so for example, the perma frost in the arctic is thawing. why should i, living in a temperate zone care about that? well, because, it's releasing methane. methane is something, in a hundred years, it's 20 times greater, in 20 years, it's 80 times greater than carbon dioxide. and that's warming the atmosphere even more. which then causes more melting of the permafrost. it causes more melting or thawing of the permafrost. more melting of the ice sheets and the glaciers. and that's raising sea level. and just so you know, 90% of the extra heat that's been absorbed by...

Even a small percentage of that amount is a large number. and amount is a large number. and that gives _ amount is a large number. and that gives us — amount is a large number. and that gives us an _ amount is a large number. and that gives us an idea, i suppose the really gloomy part has to be that we are in the world which is trying to fight the ever increasing global warming, at the moment. as long as there is any warming at all there will be more ice melt? that's exactly right there is a lag in the earth system. what we know is a lot of extra heat being absorbed has actually been absorbe...

Specifically. but looking at a foot of sea level rise by 2050 which is still in most of our lifetimes and what it's going to do to a place like miami, it's pretty shocking. >> yeah, katy, it is great to be back with you. and this is, you know, a sobering report, there's no question about it. there is some increased confidence. we have more observations, more data, we're measuring what's happening with these ice sheets, with these collapsing ice shelves. our models, our climate models are more comprehensive. they better handle some of the complex physics of how ice behaves in these ice sheets. ...
