How’s this for irony? Global warming has gotten so bad in Alaska that it is no longer possible for oil companies to go up there and drill for more oil. According to a story in the Houston Chronicle:

A state rule says heavy exploration equipment can be used on fragile tundra only when the ground is frozen to 12 inches deep and covered by at least 6 inches of snow.

However, because winters in the Arctic are becoming shorter, the number of days the tundra meets those conditions has shrunk from more than 200 in 1970 to only 103 last year, a state document notes.
