Northeast Greenland is home to the 79° N Glacier—the country’s largest floating glacier tongue, but also one seriously threatened by global warming. Warm water from the Atlantic is melting it from below. However, experts from the Alfred Wegener Institute have now determined that the temperature of the water flowing into the glacier cavern declined from 2018 to 2021, even though the ocean has steadily warmed in the region over the past several decades. This could be due to temporarily changed atmospheric circulation patterns.
