Scientists Announce Proof of Mega-Droughts – While Californians worry about the three-year drought dragging on another season, researchers say climate change soon could create much longer dry spells – lasting decades or even centuries. Scientists from the University of California, Davis, this month announced the first proof of such mega-droughts after studying mineral formations in caves along the Sierra Nevada. Just as important: The big droughts seem connected to rapid warming, especially in the Arctic. The dry spells occurred during a climate warm-up that started about 15,000 years ago after the last Ice Age, says Davis geochemist Isabel Montanez. Scientists fear climate wasming this century might similarly trigger mega-droughts that would devastate agriculture, increase wildfires and cut water supply in the nation’s most populous state.
