The heating of the planet is pushing Earth’s polar bear population to its limit, and according to a new study they could have fewer than 100 years left before extinction.
“Without a doubt, it’s climate change,” Copland said, noting the ice shelf is melting from both hotter air above and warmer water below.Ice shelves are hundreds to thousands of years old, thicker than long-term sea ice, but not as big and old as glaciers, Copland said. Canada used to have a large continuous ice shelf across the northern coast of Ellesmere Island in the Canadian territory of Nunavut, but it has been breaking apart over the last decades because of man-made global warming, according to White. By 2005 it was down to six remaining ice shelves, she said, but “the Milne was really the last complete ice shelf.”
“There aren’t very many ice shelves around the Arctic anymore,” Copland said. “It seems we’ve lost pretty much all of them from northern Greenland and the Russian Arctic. There may be a few in a few protected fjords.”
Global warming is good.
time to call d. trump .
Given the more advanced equipment to take various scientific measurements these days, the cases of global warming has appeared more convincing than ever. Are those trying to dismiss the problems hiding their heads in the sand in order to make themselves feel better?
They said the same thing in 1934 then In 1974 the ice caps grew so large scientists wanted to cover them in black soot to melt them!! The climate is cyclical 1000s of years of historical data proves this. The climate has always changed the fear mongering hasn’t.
Ice melting in the summertime? Shocker

Don't forget, we are always just one extinction level event away from an ice age. 😉
They will find a way to tie Covid19 into Climate Change, but we are suddenly back to Global Warming.
Oh, that's a thing again?
So now that it's not as cold up here I'd like to invite all you Americans to visit Saskatchewan when the border opens for some of the best hunting and fishing around. Bring your money.
who needs an ice shelf, anyway?
