Subject	Re: Communication with AR4 WGI Chapter 3
Resending. Apologies! I changed Jean's email incorrectly. This one is now correct. Phil David, I will send you this once we post the ZOD on the WG1 web site in mid-Jan05. Our diagrams are in a state of flux. Most of the temperature and precipitation trend maps are being done in Asheville and I should be getting them later this week or early next. We will be showing maps for the whole 20th century, but others will focus on the period since 1979. You might like to consider avoiding duplication by using these - eventually they will be 1979-2005 (poss 2006). Trends of indices in extremes will likely be similar, but with +/- signs on maps. Nothing has been decided yet, though, and I expect a significant part of our time at LA2 will be taken up by discussing/improving diagrams in our ZOD. You can help us by sending comments to WG1 on the relevant parts - which are likely to be almost all.

The chapter in which I am involved will depend heavily on inputs from a number of chapters in the WGI report. Hence, I contacting the CLAs of the relevant chapters, including chapters 2, 3, 4, 5, 6, 7, and 9, by email to discuss ways to ensure effective communication between our chapters and to avoid undue overlap between respective chapters in WGI and our chapter in WGII. Your chapter on "Observations: Surface and atmospheric climate change" is a key chapter in WGI and it is important that what we say in our chapter in WGII follows from and agrees with your chapter. I would be very happy to discuss ways to ensure effective communication between our two chapters. Specific aspects from your chapter of relevance to our chapter include observed changes in regional temperature and precipitation, both means and extremes. We plan to use a figure in our chapter showing a global map of observed temperature trends over the last 30 years (?) overlaid with locations of significant observed changes in natural and managed systems. We want to make sure that this is based on the same dataset(s) that you will be using to show the observed temperature trends. In practice, almost everything in your chapter will be relevant to our chapter. I would be grateful if you could send me a copy of your ZOD after it is completed, so that I can make sure that our chapter is consistent with yours. I am happy to send you a copy of our ZOD, if you would like to read it. I will not be coming to the WGI LA meetings until LA3, when I will be involved as a review editor. It will be important that we have already established effective communication before then. I look forward to working with you over the next two years to ensure that the IPCC AR4 is the best possible assessment.
