The fabled Northwest and Northeast passages are now open. That makes the North Pole an island for the first time in human history, most likely for the first time “since the beginning of the last Ice Age 125,000 years ago.”

But whether a record is set this year has little bearing on the future of the Arctic. The National Snow and Ice Data Center’s Mark Serreze said last Wednesday, “No matter where we stand at the end of the melt season it’s just reinforcing this notion that Arctic ice is in its death spiral.”

And that, of course, means polar bears populations will also enter a death spiral.
