Is an ice-free North Pole unusual?

You've seen the recent headlines full of alarm, North Pole could be ice-free this summer, scientists say (CNN) and Exclusive: No ice at the North Pole, Polar scientists reveal dramatic new evidence of climate change (the Independant).

The ice retreated to a record level in September when the Northwest Passage -- the sea route through the Arctic Ocean -- opened up briefly for the first time in recorded history.

Tom Nelson adds a little perspective:

Except that the Northwest Passage was successfully navigated in years like 1906, 1940, 1941, 1942, 1944, 1957, 1969, 1977, 1984, 1988, and 2000.

I guess when you are the main stream media, you don't want a little thing like facts to interfere with your alarmist story.
