I think I know his source – and it is not even Fox News. I can say with some confidence that it is a place where the sun never shines.

Finally, he claims “climate science is not real science.” Really? If one can formulate a hypothesis that can be experimentally tested in a way that provides a quantitative measure that then can be compared to the hypothesis, it is science.

Rather than counter Mr. Sigman’s opinions with numbers of my own (and actual legitimate references, as well) I would urge all Herald readers to investigate this important issue of our times for themselves. I suggest a good place to start is to consult the U.S. National Academy of Sciences, which is one of the most pre-eminent scientific organizations on the planet. The academy’s website is www.nasonline.org. The NAS is charged with the responsibility of providing our government and our citizenry with the scientific facts as they are currently known in an unbiased and nonpartisan manner.

That would be a far cry from what normally comes from the climate-change denier community so ably represented locally by Sigman.
