Greenland’s floating ice platforms — which hold back trillions of tons of ice that could cause sea level rise — are in stark decline, according to a new study.
A rediscovered sample of frozen sediment, collected more than 50 years ago, highlights the vulnerability of Greenland’s ice sheet to a warming climate.
As global warming passes certain limits, dire changes will probably become irreversible, the researchers said, including the loss of polar ice sheets and the death of coral reefs.
