Greenland's ice sheet saw an almost 12 percent meltdown on Monday, according to data released by the Danish Meteorological Institute (DMI). The amount of ice melt is not only abnormal but also taking place a month before its usual occurrence.
The scientists who made the report were taken aback by the discovery. According to Peter Langen, a climate scientist at DMI, the researchers had to recheck and ensure that their models were still working properly. Previous reports state that meltdowns that cover more than 10 percent area usually happen in May; however, none at the scale that is being witnessed now.
According to the DMI report, warm air that advanced from the southwest, which brought rain in its wake to the coast, was a factor driving the ice melt. The situation is akin to one observed in 2012, when 95 percent of the ice sheet surface experienced melt; however, even then, the melt wasn't as early or extensive as the one noticed on Monday.
"It is a very unusual situation, especially so early in the year, with very cold air and deep low pressures system to the west and east of Greenland and very warm air forming a 'cap' over the island," said Martin Stendel, DMI climate scientist. "This helped to force a frontal system with very warm air up the west coast bringing rain over the ice sheet."
