LA Times: A few years ago a group of researchers used computer modeling to put California through a nightmare scenario: Seven decades of unrelenting mega-drought similar to those that dried out the state in past millennia. "The results were surprising," said Jay Lund, one of the academics who conducted the study. The California economy would not collapse. The state would not shrivel into a giant, abandoned dust bowl. Agriculture would shrink but by no means disappear. Traumatic changes would occur...

Climate Central: If you think the drought in California is bad, you ain't seen nothing yet. New research indicates that climate change is giving a boost to the odds of long-term drought across the Southwest. The research, published Thursday in the Journal of Climate, puts the chances of a megadrought lasting 35 years or longer at up to 50 percent in the region. It would be a drought of epic proportions that would wreak havoc on the region's already tenuous water supply for its growing population. "It's been...
