It is well known that glaciers are melting as a result of global warming. Canada, in the north, is, of course, one of the biggest victims. According tomedia reports, 6 local time, Canada’s last complete Arctic ice shelf collapsed, according to official data, in the end of July alone in two days to disappear 40 percent of the area, larger than the area of Manhattan, New York, The United States.
The Milne ice shelf is located on the edge of Elsmere Island, in the sparsely populated Nunavut region of northern Canada. The Canadian Sea Ice Service says above-normal temperatures, wind at sea and open water in front of the ice shelf are all contributing factors to the ice shelf’s breakage.
“The whole city is so big, it’s a big block of ice,” said Luke Copeland, a glaciologist at the University of Ottawa and a member of the Milne Ice Shelf Research Group. “If you look at it, the ice shelf is about 80 square kilometers smaller, compared with about 60 square kilometers on Manhattan Island in New York. “It’s the largest existing ice shelf, basically broken down,” Copeland said. “
It is understood that over the past 30 years, the Arctic has reached twice the rate of global growth, this year the polar temperature has been rising, polar sea ice area is the lowest in 40 years.
This year’s summer temperatures in the Canadian Arctic are 5 degrees Celsius above the 30-year average, Copland said. This has threatened smaller ice shelves because they do not have large glaciers that keep their cold and melt quickly.
The collapse of the ice shelf in the Canadian Arctic is another sign of global warming.
