A Climate Falsehood You Can Check for Yourself 

David Friedman

One problem in arguments about climate (and many other things) is that most of the information is obtained at second, third, or fourth hand, with the result that what you believe depends largely on what sources of information you trust. One result is that people on either side of the argument can honestly believe that the evidence strongly supports their view. They trust different sources; different sources report different evidence. It is thus particularly interesting when on some point, even a fairly minor one, you can actually check a claim for yourself. I believe I have found an example of such a claim.
