The slow decline of the Taku Glacier in Alaska became apparent in newly released photos shared by NASA's Earth Observatory.
The massive glacier, measuring 4,860 feet from the surface of the floor, has been gaining mass for almost 50 years, but now it appears to be shrinking.
A pair of satellite images taken in August 2014 and August 2018 show the ice platforms where the glacier meets the Taku River, retreating for the first time since 1946.

Not only did these signs of retreat arrive about 80 years ahead of schedule, Pelto told Live Science, but they also stifled the symbolic jolt of hope in the race to understand climate change.
"It's a big deal for me because I had this one glacier I could hang on to," Pelto, a professor at Nicholas College in Massachusetts, told NASA. "But not anymore. This is the result of climate change: 250 and alpine glaciers: 0.
Of the 250 mountain (or" alpine ") glaciers that Pelto has studied globally, Taku is the only one that has not started clearly
Scientists say the Taku Glacier was gaining mass between 1946 and 1988, growing by about a foot a year. This progress stopped before the glacier began to retire last year.

Transition occurs so quickly shows that climate outweighed the natural cycle of advance and retreat, the glacier that usually goes through, "says Pelt.
