Greenland's Ice Sheet Losing Nearly 200 Cubic Kilometers Annually, Study Reveals
Satellite data from 2010 to 2022 highlights alarming ice loss, contributing significantly to global sea level rise.
- Greenland's ice sheet, the world's second-largest, has been shrinking by an average of 196 cubic kilometers annually between 2010 and 2022.
- Researchers used data from ESA's CryoSat-2 and NASA's ICESat-2 missions, employing radar and laser measurements to track ice loss with high accuracy.
- The total ice loss over the 12-year period amounts to 2,352 cubic kilometers, nearly equivalent to the volume of Africa's Lake Victoria.
- This melting has already caused a 13.6-millimeter rise in global sea levels since 1992, with potential for a catastrophic 7-meter rise if the ice sheet fully melts.
- The study underscores the variability of ice loss, with annual rates ranging from 4 to 464 cubic kilometers depending on environmental conditions.
