Record heatwaves in Greenland and Iceland accelerate ice melting, raising sea levels and threatening coastal areas.

In May, Greenland and Iceland experienced record-breaking heatwaves, with Greenland's ice sheet melting 17 times faster than average. Human-caused climate change made such extreme temperatures 40 times more likely. The rapid melting contributes to rising sea levels, threatening coastal areas and low-lying islands. It also impacts indigenous communities in Greenland, who face dangerous travel and hunting conditions due to thawing ice. The heatwave could slow down the Atlantic Meridional Overturning Circulation, affecting global weather patterns.
