IPCC and Solar Correlations

Here’s a post which I wrote last June but didn’t post up at the time because the NAS Panel report came out and I had other pressing matters to comment on. My post as then drafted started: Last week, through Chefen, Jean S and myself, here here here and here , we showed that MBH98 […]

The IPCC 4AR Zoning Variance: a CA Contest

A comment by Judith Curry reminded of a suggestion that Ross McKitrick sent me for a CA contest. Judith said: There is no fear of H/W making it into IPCC4, the closing for papers to be accepted was over a year ago. What Judith said here is what IPCC rules said prior to IPCC AR4. […]

IPCC and Glaciers

It seems quite possible to me that study of glacier changes would actually shed some useful light on the relative levels of the MWP and modern warm period. I’m quite prepared to let the chips fall where they may (although I would deny that this would vindicate the statistical falsehoods of the Mann HS, any […]

Acceptance Dates

I posted up information on IPCC publication deadlines, which are presumably there to ensure that authors do not play favorites. Here are dates of submission, acceptance and publication of some studies that have been discussed recently on this blog. These should be compared against WG1 deadlines of August 12, 2005 for being supplied to TSU, […]

IPCC WG1 Publication deadlines

I’ve previously discussed IPCC WG1 publication deadlines in the context of Wahl and Ammann [2006], where the authors seemed to make last-ditch efforts to comply with IPCC WG1 publication deadlines, but ironically failed to comply with the letter of the deadlines. There have been some other high-profile "late-breaking" articles (Osborn and Briffa [2006], Wahl et […]

IPCC 4AR – Access to Review Comments

Last week, the review of the second draft of the IPCC Fourth Assessment Report began. Some readers here are IPCC reviewers and may not be aware of the following provision of Appendix A to the Principles Governing IPCC Work http://www.ipcc.ch/about/app-a.pdf, which states that: "All written expert, and government review comments will be made available to […]

IPCC 4AR and Ammann

Luboà…⟠Motl pointed out that IPCC "needs" Ammann and Wahl in a peer reviewed journal. Let’s re-visit some curious timing issues, which Ian Castles brought up before and which need to be re-examined with the re-submission. The IPCC WG1 timetable (thanks to Ian for this) says the following: Third Lead Author meeting, December 13 to 15, […]

Mosquitos, malaria and the IPCC "consensus"

This article was brought to my attention by Larry Huldén. It is a memorandum written by Professor Paul Reiter to the UK House of Lords on the widely disseminated idea promoted by the IPCC that climate change will produce increased ranges for mosquito-borne diseases such as malaria and dengue fever. If people are in any […]

Ian Castles on IPCC Economic Assumptions

Ian Castles, the well-known economist, has sent in the following post as a comment on another topic, which I have taken the liberty of posting up here. Ian writes:

Crowley and North [1991]

A little relief from Mann source code (but don’t worry, I’m not finished with it.) In my post on IPCC 1990 arising out of the controversy about the WSJ editorial, I referred to the following quote from the Executive Summary to chapter 7 (p. 200), which stated (having the Younger Dryas in mind): We conclude […]
