Canadian Arctic Not What It Used To Be

In more depressing news about the state of the Arctic, a 4,500 year-old shelf of ice has broken off from Ellesmere Island. The BBC reported that a nineteen-square-mile section, about three times the size of Manhattan, is now floating around the ocean. It's getting bad on the other islands of the Canadian Arctic Archipelago too. What people often forget is that not only is this a scary symptom of global warming, but these ice shelves are actually very fragile ecozones that are now in serious danger of disappearing.

I've always been fascinated with Arctic exploration. When I was a kid I loved the stories of explorers such as Hudson and Barents navigating between ice floes and having run-ins with polar bears. I loved looking at maps of the Arctic and wondering about all those islands with the strange names--Ellesmere, Baffin, Devon. I wondered what it would be like to be trekking across their huge expanses of ice. Looks like I'll never know.
