Waterwise Wednesday: I’m Melting

. . .So said the Wicked Witch of the West. And Greenland’s ice sheet too.

The second largest ice sheet in the world, lost a near record breaking 11 billion metric tons in a single day to the ocean last Thursday, August 1. (That’s about 4.4 million Olympic swimming pools worth of water.) Unusually high temperatures, 30 to 40 degrees above average, contributed to the record melt. Globally, heatwaves also created ice melts in Arctic tundra, Greenland fjords and European Alpine peaks where it usually stays permanently frozen.
