Warm, wet conditions rapidly kicked off the melt season this weekend, more than a month-and-a-half ahead of schedule. It has easily set a record for earliest melt season onset, and marks the first time it’s begun in April.
Little to no melt through winter is the norm as sub-zero temperatures keep Greenland’s massive ice sheet, well, on ice. Warm weather usually kicks off the melt season in late May or early June, but this year is a bit different.
Record warm temperatures coupled with heavy rain mostly sparked 12 percent of the ice sheet to go into meltdown mode (hat tip to Climate Home's Megan Darby). Almost all the melt is currently centered around southwest Greenland.
