New NASA Video: Massive Greenland Glacier on the Move

December 6, 2015

NASA Earth Observatory:

Zachariæ Isstrøm has become the latest Greenland glacier to undergo rapid changes in a warming world. Research published November 2015 in Science found that Zachariæ Isstrøm broke loose from a stable position in 2012 and entered a phase of accelerated retreat.

The consequences will be felt for decades to come. The reason? Zachariæ Isstrøm is big. It drains ice from a 91,780 square kilometer (35,440 square mile) area of northeast Greenland. That’s about 5 percent of the Greenland Ice Sheet. The glacier holds enough water to raise global sea level by more than 46 centimeters (18 inches) if it were to melt completely. It is already shedding billions of tons of ice into the far North Atlantic each year.

“North Greenland glaciers are changing rapidly,” said lead author Jeremie Mouginot of the University of California, Irvine (UCI). “The shape and dynamics of Zachariæ Isstrøm have changed dramatically over the last few years. The glacier is now breaking up and calving high volumes of icebergs into the ocean, which will result in rising sea levels for decades to come.”

    Move along, folks—-nothing to see here!

    Just the 600 pound canary that is now shedding feathers in the arctic. We knew about the southwest of Greenland, but now glaciers in the northeast are going nuts? And we don’t want to talk about it? Amazing.
