Glaciers in Crisis: Unprecedented Melting Rates Observed Worldwide.

Steenstrup Glacier in Greenland has retreated 5 miles, thinned by 20%, doubled its ice discharge, and quadrupled in velocity between 2018 and 2021, making it one of the top 10% of glaciers contributing to the region’s total ice discharge. The rapid change highlights the vulnerability of even stable glaciers to sudden retreat due to warmer waters, with potential consequences for global sea level rise. The study suggests that even long-term stable glaciers are susceptible to sudden and rapid retreat as warmer waters begin to intrude and influence new environments.
