Hi Keith,

Of course, I agree with you. We both know the probable flaws in
Mike's recon, particularly as it relates to the tropical stuff. Your
response is also why I chose not to read the published version of his
letter. It would be too aggravating. The only way to deal with this
whole issue is to show in a detailed study that his estimates are
clearly deficient in multi-centennial power, something that you
actually did in your Perspectives piece, even if it was not clearly
stated because of editorial cuts. It is puzzling to me that a guy as
bright as Mike would be so unwilling to evaluate his own work a bit
more objectively.
