A new study highlights how a stream of warm, moist air caused excessive melting over Greenland in 2021, an increasingly common occurrence over the past decade.
Meltwater draining through an area of the Greenland Ice Sheet creates enough energy to rival that of a massive hydroelectric power station, researchers say.
Escalating an international spat, Donald Trump said Wednesday he scrapped his trip to Denmark because the prime minister made a "nasty" statement when she rejected his idea to buy Greenland as an absurdity.
As the plane neared the glacier, scientists spotted an ice-free "lake" at its front. Probes also brought back worrying data -- Helheim glacier was surrounded by warm water along its entire depth, more than 2,000 feet below the surface.
