Last week, NASA Administrator Michael Griffin told NPR that he is unsure whether global warming is "a problem we must wrestle with."

As the world's most renowned scientists concluded in the International Panel on Climate Change reports this year, the debate on global warming is over: global warming is occurring, humans are contributing to the problem and we need to curb the greenhouse gases that cause it.

It's not rocket science.

That's why Administrator Griffin's statement that he cannot say whether global warming is a real concern is so troubling.

Administrator Griffin even went as far as to suggest that global warming could be beneficial. Griffin's remarks are not only ignorant, but insensitive.

Jim Hansen, one of the world's leading experts on global warming and Director of NASA's Goddard Institute for Space Studies, told NPR that "he almost fell of his chair" when he heard Griffin's remarks and called Griffin's comments "remarkably uninformed."

Another leading climate scientist, Michael Oppenheimer of Princeton University, called for Griffin's resignation.

After hearing Administrator Griffin's astonishing display of ignorance of his own agency's research and the sheer threat global warming presents, we have reached the same conclusion.

Today, LCV launched a petition calling for Administrator Griffin's resignation. You can view and sign the petition here.
