Let's start with your 97% factoid, cited by Pres. Obama (“Ninety-seven percent of scientists agree: Climate change is real, man-made and dangerous") and many liberal media outlets. It is based on one study by Cook, et. al. which surveys abstracts of other studies, not an actual survey of the scientists' stated positions. Per Cook, 97.1% of  33.6% of these studies, or 32.6% in total, indicate an unspecified amount of global warming due to humans. 66.4% do not, and were arbitrarily set aside by Cook. A followup study by Legates, et. al., found that only 0.3% of the studies in Cook's survey explicitly endorsed Cook's position that humans are contributing some unspecified amount to global warming, in itself a far weaker claim than Obama makes. Richard Tol, Univ. of Sussex, says Cook's data are low quality, Cook's own tests show the data to be invalid, and he has not released all data for others to examine. So, poor science, completely misrepresented, but swallowed whole by you and others.
