As you all probably understand, the IPCC process relies heavily on the labors of many who are not compensated in any way to help provide the best assessment of knowledge regarding climate change. You have all been working with one or more Lead Authors of Chapter 6 Paleoclimate (the first such chapter in IPCC history!), and your labors have helped generate what we hope is a strong second order draft (SOD) of our chapter. The next draft (TOD) will be the final draft and will be published next winter (2007). Thus, we have time to make the final product even better than it already is. MOST important at this point is careful expert review of the SOD. You should all of received a formal email invitation (from the IPCC WGI Technical Service Unit) to serve as expert reviewers of our chapter (and indeed, the entire WGI SOD, if you are so inclined). But, please take a close look at our current Chapter 6, and give us feedback through the formal process. We especially need your feedback on those sections relevant to your specific contributions, but also on the entire chapter if you have time. Other chapters with paleo that might be of interest are Chapters 1, 2, 4, 5, 7, 8, and 9. Chapters 10 and 11 draw on paleo in some ways. Note that the DEADLINE is June 2, and that IPCC deadlines are for real (as we've learned the hard way!). Please note that the chapter is technically still too long - the IPCC leadership has been impressed with what we've done, and has given us more space than originally allocated, but we don't expect to grow further. Indeed, we need to make the chapter even tighter and shorter, so any comments on what could be shortened will be appreciated. As we all know, there are insights from paleo that are worth getting out, but that we chose not to include. We had tough choices to make, and hopefully, we have focused on those aspects of paleo science that are most relevant to policy makers. Our chapter should NOT be viewed as a review, and in this light, we need to focus primarily on the recent and most state-of-the-art references, rather than the whole chain of papers that led us to this point - only in really key areas can we cite the "classic" paper. Also, some important issues, such as model evaluation, climate sensitivity and climate change detection are supposed to be covered in other chapters (8, 9 and 9, respectively). And, all assessment of future change should be in chapters 10 and 11. In the rush (you can't believe how intense the last minute editing and formatting are w/ each draft), we left some names off the SOD Contributing Author list on the first page of our chapter. For this, we are truly sorry. We are also thankful that this isn't the final draft, and promise to get it right next time! As best we know from our Lead Author (LA) team, all of the Chapter 6 CA's are on the attached list, and all got formal invitations to be formal expert reviewers. Since our connections with some CAs comes via LAs, we've also cc'd this email to LAs to make sure no one is still off the CA list. Of course, if you feel you shouldn't be a CA of Chapter 6, or have any other issues, please let us know. Our goal is to have a final document that is recognized within our community, and throughout the broader climate change community, as accurate and definitive. Again, your help is MUCH appreciated. It is great to have you on the Chapter 6 team. Don't forget that the DEADLINE for expert review is June 2.
