Last month Wisconsin Rep. F. James Sensenbrenner (R-Allen Edmonds) ranking-membered a House subcommittee hearing on the Earth's climate. The Democrats on the panel produced experts in atmospheric science, oceanography, biology, and dendrochronology.
Sensenbrenner produced this twit.
Read the correspondence and then follow the links to John Abraham's thoroughgoing taking-apart of "Lord" Monckton. Monckton is cited approvingly by a wide range of conservative Republican observers,* including the Milwaukee Journal-Sentinel's ridiculous Patrick McIlheran. And of course F. James Sensenbrenner, for whom one almost feels sorry, for taking the pompous charlatan seriously.
Watching John Abraham's entire presentation requires a substantial investment in time and concentration. Because it's a vastly complicated subject and relies on a lot of interdisciplinary science and mathematics, so it can get pretty hairy.
Which makes it all the more preposterous when Republican candidate for U.S. Senate Ron Johnson dismisses it all with an absolutist hand wave. Now that is an extremist.
* To the extent that a "wide range" of conservative Republican views is available. See, e.g., the Shunning of David Frum.
