NASA Finds New, Frightening Way Glaciers Are Melting in Greenland

The Rink Glacier, the largest glacier on the west coast of Greenland, was exhibiting some strange melting behaviors during the hot summers of 2010 and 2012 that can only be described as a “warmed freezer pop sliding out of its plastic casing.” This kind of mass melt lasted four months between June and September in 2012 with a loss of 6.7 gigatons of mass.

The mass moved 2.5 miles every month for the first three months, then 7.5 miles all at once in September. That’s actually pretty speedy considering the Rink Glacier usually melts at a speed of one to two miles a year. But, still, it was slow enough that NASA had to use aerial GPS data to measure the movement.

“You could literally be standing there and you would not see any indication of the wave,” said Eric Larour of the Jet Propulsion Laboratory and coauthor of the research. “You would not see cracks or other unique surface features.”
