Report: Two ice caps in the Canadian Arctic have DISAPPEARED thanks to worldwide warming

The St. Patrick Bay ice caps on the Hazen Plateau of northeastern Ellesmere Island in Nunavut, Canada, have disappeared, in accordance to NASA satellite imagery. National Snow and Ice Details Heart (NSIDC) scientists and colleagues predicted through a 2017 paper in The Cryosphere that the ice caps would melt out totally inside of the following five years, and modern illustrations or photos from NASA’s State-of-the-art Spaceborne Thermal Emission and Reflection Radiometer (ASTER) have verified that this prediction was correct.

Mark Serreze, director of NSIDC, Distinguished Professor of Geography at the College of Colorado Boulder, and guide writer on the paper, initially established foot on the St. Patrick Bay ice caps in 1982 as a youthful graduate student. He frequented the ice caps with his advisor, Ray Bradley, of the College of Massachusetts.

“When I first frequented all those ice caps, they seemed like this kind of a long lasting fixture of the landscape,” said Serreze. “To watch them die in a lot less than 40 years just blows me absent.”

In 2017, researchers in comparison ASTER satellite data from July 2015 to vertical aerial images taken in August of 1959. They identified that among 1959 and 2015, the ice caps had been minimized to only five p.c of their former area, and shrank significantly concerning 2014 and 2015 in reaction to the specially heat summer in 2015. The ice caps are absent from ASTER images taken on July 14, 2020.

The St. Patrick Bay ice caps ended up just one-half of a group of compact ice caps on the Hazen Plateau, which fashioned and most likely attained their utmost extents through the Small Ice Age, maybe quite a few generations in the past. The Murray and Simmons ice caps, which make up the next 50 percent of the Hazen Plateau ice caps, are situated at a larger elevation and are as a result faring superior, though experts forecast that their demise is imminent as properly.

“We’ve very long acknowledged that as local weather alter takes keep, the effects would be specifically pronounced in the Arctic,” claimed Serreze. “But the loss of life of those two tiny caps that I after understood so nicely has designed local climate adjust pretty own. All that’s left are some images and a good deal of memories.”
