NASA Satellites Reveal The World's Thickest Glacier Melt 80 Years Ahead



NASA satellites reveal world's thickest glacier melts 80 YEARS prematurely due to record high temperatures

  • Satellite images reveal world's thickest glacier, Taku losing weight due to record highs
  • Expert estimates that will continue to grow until the next century, but expansion stops completely in 2018.
  • The Taku Glacier was the only one of the 250 largest in the world that was not affected by climate change

The world's thickest glacier has succumbed to the effects of climate change

A set of images released by NASA's Earth Observatory shows that the Taku Glacier in Alaska is being restored for the first time in more than 70 years.

Researchers predict that the Alpine glacier will be a one-day retreat, but the mass reduction is 80 years ahead of schedule.

Dr. Mauri Pelto, a professor of environmental science at Nichols College and director of the Northern Cascades Glacier Climate Project, has been studying Taku for 30 years and believes it will continue to expand throughout the century as it gained mass 1 feet annually from 1946 to 1988.

However, the thickening slowed down in 1989 and enlargement ended completely from 2013 to 2018.

Last year began to show visible signs of a retreat, which Pelto said is related to Alaska's record summer temperature.

<p class= "We thought that the balance of the mass in Taku was so positive that it could progress for the rest of the century," Pelto said.

"Many times glaciers will stop advancing for many years before retreats begin."

"I don't think most of us thought Taku would retire so quickly. "

Pelto has been monitoring 250 massive glaciers around the world for three decades and Taku was the only one who showed no signs of retreat.

" That's a big deal for me because I had this one glacier I could to hold on, ”Pelto said.

– But not anymore. This makes the result of climate change: 250 and alpine glaciers: 0. "

Pelto revealed the effects of climate change using images from the NASA Earth Observatory that allowed him to analyze changes in the transitional snow line – the border where snow transition bare glacier ice.

  Taku is considered the thickest glacier in the world, measuring 4,860 feet from the summit to the bottom and is also the largest in the Juneau ice field.

Taku is considered to be the thickest glacier in the world, measuring 4,860 feet from top to bottom and the largest in the Juneau Icefield.

At the end of summer, the height of the snow line represents the point at which the glacier experiences the same amount of melting and snow accumulation.

If the glacier experiences more melting than snow accumulation during the season, the snow line of the glacier is shifted to higher altitudes.

Researchers can calculate the net changes in the mass of the glacier by tracking the displacement of the snow line that Pelto was able to see in the images.

"We thought that the mass balance at Taku was so positive that it would be able to progress by the end of the century," Pelto said.
