Oy!!

What else can you say about this poll of congressmen on the existence of man-caused global warming? How can the overwhelming majority of one of the two major parties in the United States of America in the 21st century have these beliefs? I note in the comments that several of the Repubs hang their vote in the poll on the qualifier "beyond reasonable doubt", but that perhaps reveals more than you might think. Are they cravenly obfuscating and trivializing to pander to their head-in-the-sand constituents rather than responsibly facing up to the problems we are passing on to our grandchildren? And what about the concept of risk? Must the prospect of such a catastrophic phenomenon be 100% certain before action is taken?
