SOME 'scientific consensus': NASA's administrator Michael Griffin, questions the need to combat global warming:

NASA administrator Michael Griffin is drawing the ire of his agency's preeminent climate scientists after apparently downplaying the need to combat global warming.

In an interview broadcast this morning on National Public Radio's "Morning Edition" program, Griffin was asked by NPR's Steve Inskeep whether he is concerned about global warming.

"I have no doubt that a trend of global warming exists," Griffin told Inskeep. "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," Griffin said. "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."
