Impact Of A Warming Climate On The Sierra Nevada And California’s Water

/in , /by /Water Deeply (New York)by Tara Lohan

Imagine a California where springtime temperatures are 7F warmer than they are today, where snowmelt runoff comes 50 days earlier and the average snowpack is just 36 percent of the 1981–2000 average. That may be the reality by the end of the century if we don’t curb greenhouse gas emissions, say researchers from the University of California, Los Angeles. A recent report from the UCLA Center for Climate Science analyzes how climate change will impact the Sierra Nevada and what that will mean for water resources.

Editorial: Water Investment Must Include Flood Preparation

The next huge natural catastrophe to strike California might not be an earthquake. New research suggests that a major flood could inundate large swaths of California in the next few decades. The last “200-year flood” was more than 150 years ago, and climate change is jacking up the odds of a repeat sooner rather than later. In order to prepare, state water officials must rethink whether big, costly dams really are the best investment of limited resources.

California Delta A Flash Point For Conflict As Climate Change Unfolds

/in , /by /Water Deeplyby Matt Weiser

California’s Sacramento-San Joaquin Delta is vital to water supplies for 25 million people and 4 million acres of farmland. It is linked to the Pacific Ocean via San Francisco Bay, which makes this water supply uniquely vulnerable to sea level rise. Yet understanding sea level rise in the Delta is complicated. The largest estuary on the West Coast of the Americas, it consists of some 70 islands and more than 1,000 miles of levees. It is also fed by California’s two largest rivers, which drain the Sierra Nevada range.
