Attachment: Dear Sarah, Ben and I have had some long discussions about this paper, and I have made quite a few changes as a consequence. Most of these are minor -- but I realized that my statement that the peak cooling depended logarithmically on the sensitivity was potentially confusing. For this to be the case one has to have a relationship like Tmax = A + B ln(S) which implies odd results for very low sensitivity. Instead, I have fitted a relationship of the form Tmax = A [S**n] which gives Tmax = 0 when S = 0. I have fitted a similar relationship to the decay time results, and I have done the same for the LG98 results. All this information has been added to the manuscript. It helps in understanding the differences between us and LG98. I had hoped to send this off earlier this week, i.e., before I go to Buenos Aires (tomorrow), but I never received the copyright form from you. Then I remembered that you were at that IPCC meeting in Ireland. So I have asked Liz Rothney to send the ms off next week as soon as she gets the copyright form from you. So please fax this back (303 497 1333) as soon as possible. Best wishes, Tom.
