Satellite data confirms alarming rate of polar ice sheet melting.

The Earth's ice sheets have lost enough ice over the last 30 years to create an ice cube 12 miles high, according to new research. The Greenland and Antarctic ice sheets are shrinking at a frighteningly rapid pace, with ice sheet melting increasing six-fold over the past 30 years due to record levels of planet-heating pollution. The polar ice sheets lost more than 8.3 trillion tons of ice between 1992 and 2020, with the worst year for ice sheet loss being 2019. The loss of ice is having a significant impact on the oceans, pushing up sea levels by 21 millimeters, and now accounts for a quarter of all sea level rise.
