New Climate Record Shows Century-long Droughts In Eastern North America

A study of stalagmites in West Virginia apparently boosts the idea that solar variation has caused long droughts (century-long, even) in North America

The researchers, however, don't appear to be CO2 skeptics:

The climate record suggests that North America could face a major drought event again in 500 to 1,000 years, though Springer said that manmade global warming could offset the cycle.

“Global warming will leave things like this in the dust. The natural oscillations here are nothing like what we would expect to see with global warming,” he said.

Actually, I am not sure whether he necessarily means that the global warming offset will be a bad thing. Anyhow, it's all more evidence that nature was cruel even before civilisation came along, but that's still far from reason for humans to go about risking inducing their own climate problems.
