Griffin blames NPR for global warming controversy.

“All I can really do is apologize to all you guys…I feel badly that I caused this amount of controversy over something like this,” said NASA administrator Michael Griffin, who recently told NPR that he doesn’t believe global warming is a “problem.” He went on to blame NPR, adding, “Doing media interviews is an art. Their goal is usually to generate controversy because it sells interviews and papers and my goal is usually to avoid controversy.”
