After decades of Arctic sea ice getting faster, models suggest a dramatic reversal is coming

Will ice floating in the Arctic Ocean move faster or slower over the coming decades? The answer to this question will tell us whether marine transportation can be expected to get more or less hazardous. It might also have ...

Rocks beneath Antarctic Ice Sheet reveal surprising past

The West Antarctic Ice Sheet is shrinking, with many glaciers across the region retreating and melting at an alarming rate. However, this was not always the case according to new research published last month (April 28) in ...

Evidence of Antarctic glacier's tipping point confirmed for first time

Researchers have confirmed for the first time that Pine Island Glacier in West Antarctica could cross tipping points, leading to a rapid and irreversible retreat which would have significant consequences for global sea level.
