How climate change spurs megadroughts
On an afternoon in late June, the San Luis Reservoir – a nine-mile lake about an hour southeast of San Jose, California – shimmered in 102-degree heat. A dusty, winding trail led down into flatlands newly created by the shrinking waterline. … That day, the reservoir, California’s sixth-largest and a source of water for millions of people, was just 40% full. … Depending on how you look at it, California – and most of the American West – has either entered its third catastrophic drought of the past 10 years, or has been in a constant, unyielding “megadrought” since 2000. Reservoirs are emptying; lawns are turning brown; swaths of farmland that have coaxed lettuce, almonds, and alfalfa out of the dry ground for decades are going fallow.
