This has been news everywhere except the US "mainstream media" for almost 3 weeks.
The Grand Forks Herald even ignores the story, but maybe they are waiting for the AP to send them the story. The AP is sorta like the Grand Forks Info Center where reporters can get their story without actually having to do any research on their own.
An outspoken Herald blogger, The City Beat is a big believer of man-made global warming, but I wouldn't expect him to mention it anyway. He claims he only has time to cover the city and the university so we won't expect anything soon until he runs out of things and mentions his stands on politics and global warming again.
