Meltwater lakes on a Greenland ice sheet.

Sea levels could rise much faster than expected, data from Greenland shows

Greenland’s largest ice cap is melting at a much faster rate than expected, a new study has revealed, suggesting it will add six times more water to sea level rise than previously thought. And the trend may not be limited to Greenland, scientists worry.

The study used GPS measurements and computer modeling to estimate the amount of ice lost due to climate change Greenland Northeast Ice Flow (NEGIS), a major ice flow that drains ice and meltwater from Greenland’s ice-covered inner basin.
