But are the lakes that form beneath great ice sheets long-lived and stable, collecting and spilling water at a steady rate? Or are they subject to cycles of filling and rapid flushing, like those that form beneath Iceland's ice caps?doi:10.1038/4401000a...
[01:10.24]The East Antarctic Ice Sheet holds the majority of world's glacier ice. [01:16.48]It was thought to be less affected by worldwide temperature rises [01:21.76]compared to the ice sheet in West Antarctica or G...
000 years ago, the ice sheet in West Antarctica partially melted and shrunk to a size even smaller than today. But instead of collapsing, it began to regrow later.
Forty million years ago, Antarctica grew massive ice sheets for the first time. The ANU study shows how these ice sheets stayed low, wet, and relatively warm for millions of years. The current Antarctic ice sheet is the largest block of ice on Earth, covering more than 14 million square ...
It is almost impossible to imagine what working in Antarctica is like. There are a few people who have been there to work and here's what they have to say
in ice sheet modelling, the concept of Marine Ice Cliff Instability (MICI; Fig.1b), i.e., that once ice shelves have collapsed ice cliffs become unstable and fall down if higher than∼90 m above sea level, leading to accelerated collapse of ice sheets10. MICI is a process that ...
As our planet heats up, large ice sheets in Greenland and Antarctica will melt, potentially triggering several feet of increased sea level rise. If the entire Antarctic ice sheet melts into the ocean, it could lead to dozens of feet of sea level rise, likely enough to wipe out entire...

They calculated that the ice was retreating as much as 40 to 50 metres per day during this period, a rate that equates to more than 10 kilometres per year. In comparison, modern satellite images show that even the fastest-retreating grounding lines in Antarctica today, for example in Pine ...
