Subject	Re: VERY URGENT HELP NEEDED TO ADDRESS FINAL DRAFT PROBLEM
Hi Keith and Eystein - thanks for the timely and helpful (very) feedback, Keith. Your suggestions for 4 and 5 seem fine, and I wonder only about 6. I too am not sure where the final clause came from, but I'll guess it was a suggestion of Stefan's that then stood the text of time. In the spirit of trying hard not to change the meaning of bullets in the ES from what the LA team agreed to in Bergen, what about changing this clause in the ES to read "natural recovery", i.e.: and it is very unlikely that this warming was merely a natural recovery from the pre-20th century cold period." This takes away the ambiguity, and does serve to address a widely held misconception outside of our community - or at least to phrase the issue in terms that some might find more useful. If we keep this phrase, then I would suggest restating the entire ES sentence at the end of 6.6.3. Is this ok? Again, I'm motivated by our team agreement - I do think we could delete this phrase since it's more repetitive than new meaning, but would rather not unless it really does not work. Personally, I like it as modified above, because it hammers the important point from a slightly different perspective - one that seems to be on the minds of the public still. Thanks, both, for letting me know what you think fast. best, peck Hi Peck and Eystein In response to Points 4-6 4. Add the following after past 1300 years. on line 13 page Y-33 "Considering the recent instrumental and longer proxy evidence together, it is very likely that average Northern Hemisphere temperatures during the second half of the 20th century were warmer than any other 50-year period in the last 500 years. " Do not put anything in Box 6.4 which is written frolm the reverse perspective - evidence of medieval period not good enough to say warmer than now. Also confuses statements about 500 years and longer (1000 year ) Medieval ,time. 5. The person who says this has not read the text - see lines 28-33 on Y-32 where I think this is well covered. 6. If you read the text on lines 1-10 of PAGE Y-38 I think this meaning is clearly conveyed. It is not in the same words -but easily supports the ES statement. HOWEVER, I do not like the last part of the statement (and not sure where this came from) because it is ambiguous and anyway implied by prior statement. I strongly urge you to remove the section "and it is very unlikely that this warming was merely a recovery from the pre-20th century cold period." These would sort things out I believe cheers Keith At 19:26 05/10/2006, you wrote: Hi Keith and Tim - we just got the attached consistency feedback doc from the TSU, and I've added my thoughts in red. We need your feedback on items 4-6 REALLY FAST. Tim, if Keith's not around to help, please do the job - the TSU has zero time to give us. I think the solutions to #5 and 6 are easy as I suggested (although I don't have confirmation from Susan or Martin that we can just do as I suggest, but it seems logical to me - if you can suggest an even better solution, pls do. I'll send the official chap 6 final draft text next - at least as it stands today. thanks for dealing with this, perhaps before you go to sleep this evening. Best, Peck -- Jonathan T.
