For those who always insist on looking at the bright side of life, here?s one positive from the gloom and doom of global warming. Destruction of the planet is reducing the outbreak of the plague, in the western U.S. at least. Yes, that plague, as in the Black Death, the one that killed about 50 million people back in the 1500s.

According to scientists, global warming reduces the likelihood of an outbreak of the plague in the U.S. because it will be just too hot and dry for the disease. Since 1950, there have been 430 cases of death by the plague, or about seven per year. The most common carriers of the plague bacteria to human are fleas living on rats. Dampness and warm weather are a boon for both rats and fleas, says the U.S., Swedish and Norwegian scientists who prepared the study published in the Royal Society journal Biology Letters. That's the scenario if things get worse.

Scientists say that other outbreaks of plague in the U.S. that were previously unexplainable could be linked to climate change in the Pacific Ocean. Outbreaks occur during times of warm, wet conditions and all of the 430 cases of the plague in the U.S. were in the west. With future climate change, the western U.S. can expect drier conditions and more heat waves means fewer fleas.

But the flip side is that global warming could spread plague outbreaks in other parts of the world, such as Africa, faster with the shift to moister conditions. I think this is one instance where given the option of ignoring global warming in favor of a plague outbreak is a no-brainer. Fleas and rats, rest easy.

So, what they are saying is that global warming sucks so hardcore that even the plague won't deal with it. ;D

I think that is a nice pro-green slogan.

I thought the plague started causing mischief in 1347…

fleas
written by canito, December 23, 2009

This season has been the worst flea season on the East Coast that anyone can remember. It is now December and I am still battling indoor fleas and have been since August. Unfortunately a consistent 32F for 5 days has not happened yet and so they are in the car and I have not
been able to bring myself to subject my house to that temperature in doors for 5 days. Pesticides aren't working and daily vacuuming is also failing. Hopefully replacing the carpet with pergo will help. But the flea population is not going down on the East Coast it is going up. As is the bedbug population.
