Bush Admin's Fuzzy Science... Editing Climate Reports, Censoring Scientists...

In a report, Piltz says Cooney added this line "... the uncertainties remain so great as to preclude meaningfully informed decision making. ..." References to human health are marked out. 60 Minutes obtained the drafts from the Government Accountability Project. This edit made it into the final report: the phrase "earth may be" undergoing change made it into the report to Congress. Piltz says there wasn't room at the White House for those who disagreed, so he resigned.

"Even to raise issues internally is immediately career limiting," says Piltz. "That's why you will find not too many people in the federal agencies who will speak freely about all the things they know, unless they're retired or unless they're ready to resign."

Jim Hansen isn't retiring or resigning because he believes earth is nearing a point of no return. He urged 60 Minutes to look north to the arctic, where temperatures are rising twice as fast as the rest of the world. When 60 Minutes visited Greenland this past August, we saw for ourselves the accelerating melt of the largest ice sheet in the north.
