Greenland does melt in the summer, but this year it started early: by May, temperatures were already breaking records and sea ice was retreating faster than usual. The country also lost 2 billion tons of ice in a single day in July. And now, the extreme heat wave that was plaguing Europe for the past week has moved up to the icy country. Europe’s major cities (and the people who live there) are finally having a break, and the heat wave is Greenland’s problem now… right? Well it turns out that heat in Greenland is everyone’s problem.
A recent NASA study found that, if warming continues at its current rate, Greenland alone could contribute 63 inches (over 5 feet) to global sea-level rise in the next 200 years — enough to swamp Miami Beach, Atlantic City, New Orleans, and parts of Boston and New York City, to name a few. But, to state the obvious, Greenland ice melt isn’t operating in a vacuum: Arctic sea ice levels are far below average right now, too.
Melting ice contributes to global heating, as well: Ice is light in color, so it reflects sunlight back into outer space. Rock or ocean, which become exposed after ice melts, are darker, so they absorb heat instead of reflecting it. This is why ice melt is a compounding problem — scientists call it a “climate change amplifier.”
More heat records are expected to be broken in Greenland in the coming days.
“Normally when you get a temperature record broken, it’s by a fraction of a degree,” Claire Nullis, a spokesperson for the U.N. World Meteorological Organization, told CNN. “What we saw yesterday was records being broken by two, three, four degrees — it was absolutely incredible.”
