Greenland Ice Sheet Mass Loss Accelerates

A landmark study published in Nature in 2025 confirmed that Greenland's ice sheet lost a record 600 billion tonnes of ice in 2024, contributing approximately 1.7 millimeters to global sea level in a single year. The rate exceeded models' worst-case projections, raising estimates for sea level rise by 2100 by 10-20 centimeters. Coastal nations, particularly in the Pacific and Indian Ocean, called for urgent international adaptation funding.
