Now We Have to Worry About Sunny Skies Melting Greenland’s Ice Sheet
All told, the new findings show that Greenland surface mass balance—a metric that factors in snowfall coming in and melting ice going out—dropped a record 320 billion metric tons in 2019 compared to the 1981-to-2010 average. That’s even worse news when you consider the island prior to was already losing six times more ice than it was in 1980. All told, 96 percent of the ice sheet’s surface saw melt in 2019. And while heat certainly played a role, the fresh research shows that freaky clear skies amplified the impacts.
