Credit where credit's due: Mayor Bloomberg has a lotta love for science (especially magnets!). Bloomberg, who studied physics in school and was an electrical engineering student, laced into the major Republican presidential candidates' we-know-better-than-science stances at an international economic forum at Columbia University yesterday. "We have presidential candidates who don't believe in science. I mean, just think about it: can you imagine a company of any size in the world where the CEO said 'oh I don't believe in science' and that person surviving to the end of that day? Are you kidding me? It's mind-boggling!" he said.

Bloomberg didn't call out any of the candidates by name when asked for specifics: "You can check the presidential candidates' speeches…I don't have time to go do it but all their speeches, everything they said," he said. So let's go through the roster: Rick Perry believes scientists "have manipulated data so that they will have dollars rolling into their projects"; Herman Cain doesn't believe global warming is real, and doesn't think climate change is a crisis; Michele Bachmann laughs in the face of greenhouse gases, calling it "manufactured science"; Newt Gingrich starred in a 2008 commercial against climate change; Ron Paul has called global warming "the greatest hoax"; and Rick Santorum thinks any change in temperature has nothing to do with mankind.

Only Jon Huntsman, a "bottom-tier" candidate at this point, has unequivocally said he believes "in evolution and trusts scientists on global warming," while Mitt Romney, hated by Republicans, has refused to denounce evolution at GOP debates in the past.
