They'll be back when it warms a bit

You may have already heard that two women explorers who were trekking through the Arctic to expose the reality of global warming had to turn back after one of the two experienced extreme frostbite on her foot. The cold weather overwhelmed their little expedition with temperatures 58 degrees below zero inside their tent. Outside temps were 100 below and worse.

But lest you get the impression that perhaps the research project members were rethinking their devotion to the global warming cause, consider what expedition organizer Ann Atwood concluded:

Atwood said there was some irony that a trip to call attention to global warming was scuttled in part by extreme cold temperatures.

"They were experiencing temperatures that weren't expected with global warming," Atwood said. "But one of the things we see with global warming is unpredictability."

How utterly convenient! If it's warm, it's global warming. And if it's cold, it's the reliable, comforting unpredictability of global warming.
