Thank you for the prompt and thorough reply. Michael Tobis --- Thank you as well, but the Wikipedia page shows that the ITCZ varies quite considerably from the equator over the Eastern Pacific Warm Pool. In any case, I found http://www.sciencemag.org/cgi/content/full/290/5500/2285 entitled "Reconstruction of the Amazon Basin Effective Moisture Availability over the Past 14,000 Years". Therein is a graph which appears to indicate that the caloric equator has been moving north for about 2000 years. This alone is enough to predict that the Amazon basin will revert to savanna, progressively from south to north. Not clear that global warming has that much to do with it. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups Global Change ("globalchange") newsgroup.
