There's a mysterious drop in malaria-carrying mosquitoes in some parts of Africa, and some say maybe it's because of climate change.

Oh, no! Global warming is bad bad bad! Maybe it's causing Hurricane Irene!

“Irene’s got a middle name, and it’s Global Warming,” environmental activist Bill McKibben wrote Thursday night in The Daily Beast. He argued that this year’s hot Atlantic Ocean temperatures and active spree of hurricanes — coupled with droughts, floods and melting sea ice elsewhere on the globe — are “what climate change looks like in its early stages.”

But what if it's doing something fabulously good?

Patterns of rainfall in these years were more chaotic in these regions of Tanzania and often fell outside the rainy season. The scientists say this may have disturbed the natural cycle of mosquito development.

But the lead author of the study, Professor Dan Meyrowitsch from the University of Copenhagen, says that he is not convinced that it is just the changing climate.

"It could be partly due to this chaotic rainfall, but personally I don't think it can explain such a dramatic decline in mosquitoes, to the extent we can say that the malaria mosquitoes are almost eradicated in these communities."

Global warming — or, as they say, "climate change" (for maximum coverage of any possible condition) — is probably not the cause of the hurricane or the big mosquito drop-off, but those who like to wring their hands about the connection between global warming climate change and anything bad that happens must apply the same kind of reasoning to anything good that happens. Otherwise they won't be able to maintain the pretense that they're all about the science.
