An international team of around 80 scientists has launched a major research expedition to Greenland to investigate how rapidly melting glaciers could affect one of the world’s most important ocean circulation systems, the Atlantic Meridional Overturning Circulation (AMOC). The five- to six-week mission is being carried out aboard the British polar research vessel RRS Sir David Attenborough as part of the GIANT (Greenland Ice Sheet to Atlantic Tipping Points) project. Researchers will use advanced technologies, including autonomous underwater vehicles, drones, ocean sensors, and satellites, to study how meltwater from Greenland’s glaciers enters the North Atlantic Ocean and influences ocean currents.

Scientists warn that increasing freshwater from melting glaciers could weaken the AMOC, a system that transports warm water from the tropics toward Europe and helps regulate global climate. A significant slowdown could alter rainfall patterns, intensify extreme weather events, raise sea levels along some coastlines, and affect marine ecosystems across the Atlantic region. While researchers stress that an immediate collapse is not expected, improving understanding of these processes is essential for accurate climate forecasting. (Reuters)
The expedition follows record-breaking heat across parts of Europe and comes at a time when Greenland’s ice sheet is losing mass at an accelerating pace. The findings are expected to improve climate models and contribute to early warning systems for future climate tipping points, helping governments and policymakers prepare for long-term environmental challenges.
