Greenland's Ice Loss 20% More Than Previously Estimated

New Study Reveals Accelerating Ice Loss Primarily from Glacier Edges, Potentially Disrupting Ocean Circulation and Accelerating Sea Level Rise

Greenland's ice sheet has lost 20% more ice than previously estimated, a total of 1,000 gigatons, primarily from the edges of glaciers where they meet the water.
The additional ice loss has been accelerating since 2000, with nearly every glacier in Greenland shrinking.
The ice loss could potentially disrupt ocean circulation patterns and accelerate sea level rise.
Researchers used nearly 240,000 satellite images to track the changes in 207 glaciers in Greenland from 1985 to 2022.
The largest losses came from glaciers that experienced the biggest changes from season to season, indicating a strong correlation between seasonal fluctuations and overall ice loss.
