These Trees Survived California’s Drought And That’s Giving Scientists Hope For Climate Change

/in , , /by /KQEDby Lauren Sommer

When California’s historic five-year drought finally relented a few years ago, the tally of dead trees in the Sierra Nevada was higher than almost anyone expected: 129 million. Most are still standing, the dry patches dotting the mountainsides.

But some trees did survive the test of heat and drought. Now, scientists are racing to collect them and other species around the globe in the hope that these “climate survivors” may have a natural advantage, allowing them to cope with a warming world a bit better than others in their species.

Environment Report: What to Watch as the City’s New Energy Agency Gets Off the Ground

/in , /by /Voice of San Diegoby Ry Rivard

Last week, the San Diego City Council took the big plunge and decided, in a 7-2 vote, to start buying and selling energy.

San Diego, along with several neighboring cities, will shortly form a “community choice” energy agency, or CCA. This is something I’ve written a lot about over the past two years, because it represents a major shift in who controls both literal and figurative power in the region.

Right now, energy decisions are made by a private company, San Diego Gas & Electric, which operates under the somewhat watchful eye of the California Public Utilities Commission and, of course, the shareholders of its parent company, Sempra Energy.

The Next Big Effort In AI: Keeping L.A.’s Water Flowing Post-Earthquake

/in , , /by /USC Newsby Gary Polakovic

Can artificial intelligence save the L.A. water supply from a big earthquake?

USC researchers have embarked on an innovative project to prove that it can. Using federal funds, experts at the USC Center for Artificial Intelligence in Society (CAIS) are working with Los Angeles city officials to find solutions for vulnerable plumbing. The goal is to make surgical improvements to strategic pipelines to keep water flowing after shaking stops.

Metropolitan Water District To Study Rainfall and Stormwater Runoff

/in , , /by /California Water News Daily

The Metropolitan Water District of Southern California has launched a new pilot program to provide vital data on the most efficient and cost-effective methods to capture and use rainfall and stormwater runoff. The $5 million pilot program will help fund the construction of new direct-use stormwater capture projects and the installation of monitoring equipment on existing projects.

Information on the costs and volume of water produced by different types of projects will be collected over three years and will inform the possible funding of stormwater capture efforts in the future. The goal is to understand the potential water supply benefits of local stormwater capture projects and how to best use that information.

California’s Power Supply Is Getting Greener. It’s Still Got Far To Go.

/in , , /by /San Francisco Chronicleby Mallory Moench

Over the past decade, California has become a globally acclaimed leader on renewable energy. Fueled by aggressive public policies, plummeting solar prices and evolving technology, the state has cut greenhouse gas emissions from its electric power supply in half since their 2008 peak, according to the California Air Resources Board.

“It’s really astounding how carbon dioxide emissions have been cut,” said Anthony Kovscek, chairman of the energy resources engineering department at Stanford University. “It’s been really remarkable how much renewable and solar we’ve been able to put on the grid and balance it.”
