Something strange is happening to Greenland's ice sheet
"What should be like a snowcone is becoming more like a popsicle, speeding up the runoff from the melting ice sheet.
When the remnants of Europe’s second summertime heat wave migrated over Greenland in late July, more than half of the ice sheet’s surface started melting for the first time since 2012. A study published Wednesday in Nature shows that mega-melts like that one, which are being amplified by climate change, aren’t just causing Greenland to shed billions of tons of ice. They’re causing the remaining ice to become denser."
