30M Tonnes/hour

Greenland Ice Loss Accelerates

Greenland's ice cap loss has surged to [30 million tonnes per hour](https://www.theguardian.com/environment/2024/jan/17/greenland-losing-30m-tonnes-of-ice-an-hour-study-reveals), a 20% increase over prior estimates. Retreat of glaciers since 1985 has contributed to a trillion tonnes of ice loss. This rapid melting raises concerns about the potential collapse of the Atlantic meridional overturning circulation (AMOC), with dire implications for global climate and sea level rise. Satellite analysis from 1985 to 2022 tracks glacier positions to record changes.
