Ice sheets melting at alarming rate, driving 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 study. The study used 50 different satellite estimates and found that Greenland's melt has gone into hyperdrive in the last few years. The combined melt from the two ice sheets soared to 410 billion tons a year from 2017 to 2020, more than two-thirds of it from Greenland. The speeded-up ice sheet loss is clearly caused by human-caused climate change.
