Unprecedented Polar Ice Loss Accelerates Sea Level Rise.

The Greenland and Antarctic ice sheets are losing more than three times as much ice a year as they were 30 years ago, according to a new international study. From 2017 to 2020, the combined melt soared to 372 billion tonnes a year, more than two-thirds of it from Greenland. The new figures "are pretty disastrous, really," said study co-author Ruth Mottram. Rising sea levels have been blamed for unprecedented and frequent floods in some of the most vulnerable countries to climate change.
