Climate change [scam] prompts debate among experts about spread of tropical diseases

The idea that climate change will bring malaria and other tropical killers to our door turns out to be an extremely controversial one among ecologists, climatologists and biologists such as Marcelo Jacobs-Lorena, who runs the "insectary" at Johns Hopkins. "It's a very complicated story," says Jacobs-Lorena.

The malaria map accompanied a 2000 article, written by Harvard biologist Paul R. Epstein, that raised the alarm about the impact of global warming on the spread of infectious diseases. It helped influence a research agenda that last year resulted in more than 4,000 studies of climate change and disease.

Climate change has not been the main cause of shifts in infectious-disease patterns over the previous couple of centuries, infectious-disease specialists note. Humans have played an important role.

Yet, one leading theory for what caused Haiti's epidemic focuses on humans. U.N. peacekeepers from Nepal, where cholera is endemic, may have caused the outbreak by allowing their septic tank to contaminate a river from which Haitians drink. If proved, this would underline the powerful impact of random events in a world of global travel and overpopulation. Many scientists, in fact, believe that such influences will dwarf the impact of climate change on infectious disease - or, perhaps, exacerbate it.
