Has Greenland Hit a Tipping Point? Scientists Are Listening to the Ice to Find Out

Scientists from universities in the United Kingdom and Greenland are studying how meltwater moves through glaciers on Greenland's ice sheet, using passive seismic monitoring to listen to the ice. Their work forms part of the Greenland Runoff Monitoring from Passive Seismology project and aims to improve understanding of how smaller processes across nearly a thousand glaciers add up to sea-level change. The research underscores the global stakes of accelerating Arctic warming and the importance of sustained field science in one of the world's most consequential climate systems.
