NASA Chief Questions Urgency of Global Warming
Morning Edition, May 31, 2007 · NASA administrator Michael Griffin defends the space agency's programs, including plans for a permanent moon base and manned missions to Mars. He also says that while NASA studies climate change, the agency has no authorization to "take actions to affect climate change in either one way or another."
The following are excerpts from Griffin's conversation with Steve Inskeep, edited for clarity:
It has been mentioned that NASA is not spending as much money as it could to study climate change — global warming — from space. Are you concerned about global warming?
I'm aware that global warming exists. I understand that the bulk of scientific evidence accumulated supports the claim that we've had about a one degree centigrade rise in temperature over the last century to within an accuracy of 20 percent. I'm also aware of recent findings that appear to have nailed down — pretty well nailed down the conclusion that much of that is manmade. Whether that is a longterm concern or not, I can't say.
Do you have any doubt that this is a problem that mankind has to wrestle with?
I have no doubt that … a trend of global warming exists .......
