Michael Griffin turned up the heat this morning on global warming in an interview on National Public Radio. http://www.npr.org/templates/story/story.php?storyId=10571499" [Broken] 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 zinger: "I have no doubt that … a trend of global warming exists. I am not sure that it is fair to say that it is a problem we must wrestle with. To assume that it is a problem is to assume that the state of Earth's climate today is the optimal climate, the best climate that we could have or ever have had and that we need to take steps to make sure that it doesn't change. First of all, I don't think it's within the power of human beings to assure that the climate does not change, as millions of years of history have shown. And second of all, I guess I would ask which human beings — where and when — are to be accorded the privilege of deciding that this particular climate that we have right here today, right now is the best climate for all other human beings. I think that's a rather arrogant position for people to take." Griffin's statement has attracted attacks from the left and praise from the right. Griffin did not deny that global warming is occurring or that we are causing it: The right is a bit premature in its praise. He merely advocated caution in doing something about global warming. It appears the left can't handle that.
