Sloan Professor of Meteorology at the Massachusetts Institute of Technology. Lindzen is known for his work in the dynamics of the middle atmosphere, atmospheric tides and ozone photochemistry. He has published more than 200 scientific papers and books.[1] He was a lead author of Chapter 7, 'Physica= l Climate Processes and Feedbacks,' of the IPCC Third Assessment Report on climate change. Lindzen has published papers on Hadley circulation, monsoon meteorology, planetary atmospheres, hydrodynamic instability, mid-latitude weather, global heat transport, the water cycle, ice ages, seasonal atmospheric effects. His main contribution to the academic literature on anthropogenic climate change is his proposal of the iris hypothesis in 2001= , with co-authors Ming-Dah Chou and Arthur Y. Hou.[5][6] He is a member of th= e National Academy of Sciences and the Science, Health, and Economic Advisory Council at the Annapolis Center for Science-Based Public Policy. Educated a= t Harvard University (Ph.D., '64, S.M., '61, A.B., '60), he moved to MIT in 1983, prior to which he held positions at the University of Washington (1964=961965), Institute for Theoretical Meteorology, University of Oslo (1965=961966), National Center for Atmospheric Research (NCAR) (1966=961967= ), University of Chicago (1968=961972) and Harvard University (1972=961983). H= e also briefly held a position of Visiting Lecturer at UCLA in 1967.[7] As of January 2010, his publications list included 230 papers and articles published between 1965 and 2008, with five in process for 2009. He is the author of a standard textbook on atmospheric dynamics, and co-authored the monograph Atmospheric Tides with Sydney Chapman.[8] Publications list (largely boring to non experts)(235 entries) http://www-eaps.mit.edu/faculty/lindzen/PublicationsRSL.html That's not meant to be appeal to authority or whatever, just setting what seems to be the necessary groundwork required to prevent an authour being dismissed out of hand.

Lindzen Program in Atmospheres, Oceans, and Climate Massachusetts Institute of Technology Testimony: House Subcommittee on Science and Technology hearing on A Rational Discussion of Climate Change: the Science, the Evidence, the Response November 17, 2010 Russell McMahon ______________ PS - my business activities include activities which may potentially provid= e and/or receive benefit from their reduction in net CO2 release to the atmosphere. I do not doubt thatthere is value in CO2 reductions where they are a "proxy" for the burning of fossil fuels or the use of fossil products as chemical feedstocks (eg plastic production) - the less we burn or consume the more there may be left for our children's children. In all related areas ALL I am interested in is the truth. I have no interest so vested that I wish to be party to the generation of disinformation or the creation or maintenance of scientific or engineering fables of any sort. --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
