Rainfall at Greenland ice summit for first time

Rain fell at the highest point on the Greenland ice sheet last week for the first time on record, another worrying sign of warming for the ice sheet already melting at an increasing rate, scientists said on Friday, August 20.
“That's not a healthy sign for an ice sheet,” said Indrani Das, a glaciologist with Columbia University's Lamont-Doherty Earth Observatory. “Water on ice is bad... It makes the ice sheet more prone to surface melt.”Not only is water warmer than the usual snow, it is also darker – so it absorbs more sunlight.
This meltwater is streaming into the ocean, causing sea levels to rise. Already, melting from Greenland's ice sheet – the world's second-largest after Antarctica's – has caused around 25% of global sea level rise seen over the last few decades, scientists estimate. That share is expected to grow, as global temperatures increase.
