First of all, don't giggle as you read this line,

"A North Pole expedition meant to bring attention to global warming was called off after one of the explorers got frostbite."

Why shouldn't you giggle? Because it gets much, much better,

"Bancroft, 51, became the first woman to cross the North Pole on a 1986 expedition. She and Arnesen, 53, of Oslo, Norway, were the first women to ski across Antarctica in 2001.

...Then there was the cold - quite a bit colder, Atwood said, then Bancroft and Arnesen had expected. One night they measured the temperature inside their tent at 58 degrees below zero, and outside temperatures were exceeding 100 below zero at times, Atwood said.

"My first reaction when they called to say there were calling it off was that they just sounded really, really cold," Atwood said.

She said Bancroft and Arnesen were applying hot water bottles to Arnesen's foot every night, but had to wake up periodically because the bottles froze.

The explorers had planned to call in regular updates to school groups by satellite phone, and had planned online posts with photographic evidence of global warming. In contrast to Bancroft's 1986 trek across the Arctic with fellow Minnesota explorer Will Steger, this time she and Arnesen were prepared to don body suits and swim through areas where polar ice has melted.

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."

I guess they didn't manage to get that "photographic evidence" of global warming because of the cold. But luckily, the very fact that it was colder than they expected is, according to the last sentence, proof of global warming.

So, by global warming alarmist logic, if they go to the North Pole and find melted polar ice, it's evidence of global warming. On the other hand, if they go to the North Pole and it's actually much colder than they expected, that's also evidence of global warming. Well then, what's not evidence of global warming according to, "The global warming is going to kill us all, man! We're gonna fry like an egg!" crowd?
