View Full Version : UC-Berkeley: California hasn’t been so parched since 1580

That's the finding by using tree rings to monitor past precipitation. Interesting way to look back in time before we had records. I wonder when or if mandatory water rationing will kick in?

As 2013 came to a close, the media dutifully reported that the year had been the driest in California since records began to be kept in the 1840s. UC Berkeley paleoclimatologist B. Lynn Ingram didn’t think the news stories captured the seriousness of the situation.

“This could potentially be the driest water year in 500 years,” says Ingram, a professor of earth and planetary science and geography.

Ingram has an especially long-term perspective. As a paleoclimatologist — a scientist who studies changes in climate by teasing data out of rocks, sediments, shells, microfossils, trees and other sources — she’s accustomed to looking back over eons. And according to the width of old tree rings (which can record the coming and going of wet or waterless stretches), California hasn’t been so parched since 1580.

“These extremely dry years are very rare,” she says.

But soon, perhaps, they won’t be as rare as they used to be. The state is facing its third drought year in a row, and Ingram wouldn’t be surprised if that dry stretch continues.

Interesting article, thanks for sharing. Too bad they can't predict with any accuracy how many years a drought may last and how, and in how many years you may expect a major flood to happen.

I was paying attention until she mentions the global warming.
