The Summary for Policymakers for the IPCC’s 4th Assessment Review has been released today. Here is the presentation. As discussed before, the actual WG1 Report was not released today. It will only be released in May 2007, the delay occurring to permit the IPCC to ensure that there is “consistency” between the Summary and the […]
What will I be looking for in the SPM4? There’s not much fun in trying to predict their temperature estimate when they’ve already leaked that it’s 2-4.5 deg C by 2100. So here are some things that I’m going to be looking for.
climateaudit was not really hijacked. The domain registration was scheduled to expire on Jan 31, 2007. An invoice for this was sent in December 2006. My credit card had rolled over since the previous payment. So when the server attempted to process the domain registration, the payment was refused. They notified me and I sent […]
Andrew Weaver in an article here says of the SPM: “This isn’t a smoking gun; climate is a batallion of intergalactic smoking missiles.” Wow. Even better than Space Invaders. There was a big front page preview of the SPM in the Toronto Globe and Mail today here all of which is worth reading, but for […]
We’ve all become rather used to graphs looking like the one that I’ve drawn below (other than the horizontal blue line that I will explain later). This, together with the corresponding graph of CO2 levels, is almost certainly same as Gore’s graphic on page 66 of Inconvenient Truth. I’ll bet dollars-to-doughnuts that some variation of […]
Wegman observed last summer that climate scientists failed to involve statisticians to an appropriate degree in the work. Yesterday Simon Tett drew our attention to Brohan et al 2006 as an explanation of uncertainties in HadCRU3. Brohan et al, of which Tett is a coauthor, used the prominent statistician, Donald Rumsfeld, as an authority for […]
Continuation of More Unthreaded.
A thoughtful article by Kerry Emanuel on overall AGW issues here.
IPCC AR4 is going to report that the difference between present temperature and late 19th temperatures is about 0.8 deg C, as opposed to the 0.6 deg C in TAR. This difference seemed a little higher to me than temperature changes from 2000 to 2005 (the last reported years in the respective reports) and I […]
As noted in a prior post, only IPCC insiders have access to the WG1 Report between the Feb 2, 2007 release of the Summary for Policy-Makers and the scheduled publication of the WG1 Report in May 2007. To my knowledge, such a procedure is unprecedented in public commission reporting. In searching for an explanation of […]
