My recent Op-Ed gave me a chance to summarize how I feel about the politicization of climate science in recent years - how it's become a bizarre litmus test for conservatism.

You can’t prove that any one of Barry Bonds' 762 home runs was sparked by alleged steroid use. But it did increase his “base state”, raising the overall odds of hitting a home run. You can’t point to any one weather extreme and say “that’s climate change”, but a warmer atmosphere increases the potential for historic spikes in temperature, and more frequent weather extremes.

America needs and deserves a president who can show that he or she understands the importance of basing public policy on the best available evidence, as the founders intended.
