Zywicki at Volokhs is unimpressed with Biden's statement that climate change is "clearly" man-made when the IPCC gave it an over 90 percent chance of being true. Somehow he sees a huge gap in the two positions.
RealClimate says, "maybe he left out the kind of caveats and qualifications you'd attach to the attribution of the recent loss of (North) polar sea ice if this were an AGU talk instead of a vice-presidential debate. Overall,though, the statement gets to the heart of the matter."
Zywicki thinks Palin's confused response, what RealClimate calls a garbled attempt to reiterate her old denial of human caused warming together with McCain's position, is "nuanced." Right.
As Biden, RealClimate, and any normal human being could point out, you have to understand a problem, or know if there is a problem, before you can find a solution. Palin's position that you don't need to understand the problem makes no sense.
In other news, McCain was a lot stronger on climate change in tonight's debate than he's been in the past. Not that it matters though, since he won't be president.
