NASA satellites reveal that the world's thickest glacier is melting 80 YEARS before the schedule due to record high temperatures

  • Satellite images reveal that & # 39; the world's thickest glacier, Taku, is losing mass due to record high temperatures
  • Expert thought it would continue to grow until the next century, but the expansion completely stopped in 2018
  • The Taku Glacier was the only one of the 250 of the largest in the world that was not affected by climate change

The thickest glacier in the world has succumbed to the effects of climate change.

A series of images released by NASA& # 39; s Earth Observatory shows that the Taku Glacier in Alaska is re-sowing for the first time in more than 70 years.

Researchers predicted that the mountain glacier would someday retreat, but the decline in mass is 80 years ahead of schedule.

Dr. Mauri Pelto, professor of environmental science at Nichols College and director of the North Cascades Glacier Climate Project, has been studying Taku for 30 years and believed it would continue to expand for the rest of the century because it gained a mass of 1 foot per year from 1946 until 1988.

However, the thickening slowed down in 1989 and the expansion came to a complete halt from 2013 to 2018.

Last year it began to show visible signs of withdrawal, which Pelto said is related to record summer temperatures in Alaska.

A series of images released by NASA & # 39; s Earth Observatory shows the Taku Glacier (left is 2014 before melting began) in Alaska is sowing (right is the current state of the glacier) for the first time in more than 70 years . Researchers predicted that the mountain glacier would someday retreat, but the decline in mass is 80 years ahead of schedule.

& # 39; We thought the mass balance in Taku was so positive that it could go on for the rest of the century & # 39 ;, Pelto said.

& # 39; Often, glaciers will stop advancing for several years before the retreats begin. & # 39;

& # 39; I don't think most of us thought Taku would withdraw so quickly. & # 39;

Pelto has been observing 250 huge glaciers around the world for over three decades, and Taku was the only one who had shown no signs of withdrawal.

& # 39; This is a big problem for me because I had this one glacier that I could hold, & # 39; Pelto said.

& # 39; But not anymore. This makes the climate change score: 250 and alpine glaciers: 0. & # 39;

Pelto discovered the effects of climate change with the help of images from NASA & # 39; s Earth Observatory, allowing him to analyze changes in the passing snow line – the boundary where snow turns into bare glacier ice.

Taku is considered the thickest glacier in the world with a dimension of 4,860 feet from top to bottom and is also the largest in the Juneau Icefield.

At the end of the summer, the height of the snow line represents the point where the glacier melts and snows accumulate.

If a glacier melts more than a snow accumulation in a season, the snow line of the glacier moves to higher altitudes.

Researchers can calculate net changes in glacier mass by following the shift of the snow line that Pelto could see in the images.
