Subject	methods - section 6.2.2
Hi all: Keith and Tim asked for specific requests in terms of what you could do for section 6.2.2. I'm hoping Valerie and Fortunat have already made enough progress that they can ask, but here's my take: 1. you have lots of methodology material in your 6.3.2.1, and this is good. It would be good to refer to this from the earlier, more general 6.2.2 2. the goal of 6.2.2 is to give the reader more confidence in paleo and to get them to read on with confidence that what they read will be of use 3. I suspect that the format V and F will be working around will be one that can first highlight chronological issues (that we can date some proxies very well, and that's what we focus on in this chapter primarily). It would be good to have the usual comforting comments about tree rings and other annual proxies. 4. The, it would be good to have the basics on how proxies reflect climate, and how we know we understand the relationship. That it is useful even if the proxy is responding to things other than climate. Seasonality, etc. Include brief overview of calibration, verification. you know the drill. 5. keep it short and not too detailed. Use lots of references - including to the most recent stuff. 6. I'm sure we'll end up modifying/improving later after we figure out what to do with the appendix 7. Need to work fast, very fast, but hopefully V and F have made real progress already. Thanks!!
