I’m posting this specifically for Klem, if he’s still reading. He asked that the cosmic ray forcing hypothesis be convincingly rebutted before he’d start taking the science proving climate change seriously. Well, since the hypothesis is predicated on Jasper Kirkby’s work, perhaps his words will help tip the scales. Kirkby built a damn fine experiment to try to measure how cosmic rays help create ionizing particles. Too bad it’s been misconstrued as feeding the denialists’ anti-reality predilections.
“People are far too polarized”, he says. No kidding. They’re polarized enough to completely get the results wrong. Climate Crock of the Week explains the study and how it pretty much shows that cosmic rays don’t account for the amount of forcing we see.
