Courtesy of OpinionJournal.com's James Taranto, we have this hilarious story of a couple of Greenpeace enviro-wackos trying to make a point about global warming.

Two U.S. explorers plan to start a four-month summer expedition to the North Pole next month to gather information on the habitat of an animal they believe could be the first victim of global warming -- the polar bear.

Lonnie Dupre and Eric Larsen plan to travel 1,100 miles by foot and canoe over the Arctic Ocean to test the depth and density of the ice in summer in a mission sponsored by Greenpeace, the environmental group said on Thursday.

According to some scientific predictions, the Arctic Ocean could become ice-free in the summer within a hundred years.

This will be the second time in the last three years that Dupre and Larsen have made the trek. They didn't go last year because...well...

Unusually heavy snow and ice last year forced Dupre and Larsen to call off a similar mission...

Yeah, that global warming thing again.
