Email 4418, Feb 1997, maybe CO2 doesn't cause malaria: "I dug up the malaria data (Italy and The Netherlands) between 1820-1930 which do show evidence of this 20 year cycle, with exacerbations in 1821, 1839, 1860, 1879, 1902, 1920. "

Did you hear that our joint proposal (with Pim Martens) is one of 1,500 now assessed by the EU? Does not look hopeful. However, maybe we can do some PR and raise the profile of the proposal a bit. What I have in mind is a letter to the Lancet relating weather and historic malaria fluctuations in Europe. In an earlier letter (1994, I may have given you a copy), the geographical association was made between areas affected by ENSO and periodic epidemics. This letter ends with an open explanation for the 20-year periods in malaria in Europe (Italy and the Netherlands). Last weeks publication in Science on a possible North Atlantic equivalent of the Nino with a period of 20 years may be of significance. I dug up the malaria data (Italy and The Netherlands) between 1820-1930 which do show evidence of this 20 year cycle, with exacerbations in 1821, 1839, 1860, 1879, 1902, 1920. I have no idea whether there are any climate data (sea temperature or otherwise) to justify a hypothesis that both phenomena. Do you have any suggestions?
