CALIFORNIA’S CLIMATE IS changing, and droughts are becoming more intense. Five climate pressures will seriously stress the state’s water system: warming temperatures; shrinking snowpack; shorter and more intense wet seasons; more volatile precipitation; and rising seas. While California is making good progress in addressing some areas of climate vulnerability, a more focused plan of action is needed.
As Hurricane Florence ground its way through the Carolinas this past weekend, climate watchers couldn’t help but notice that the size and behavior of the storm have been eerily reminiscent of Hurricane Harvey, which devastated Houston last year. What made these two hurricanes so destructive was their slow pace and the fact that they were supercharged with moisture from bathtub-warm oceans. It’s a deadly combination that leads to epic, record-setting amounts of rainfall and unprecedented flooding, amplifying damage from the high winds and storm surge typically associated with hurricanes.
For years, presidents and prime ministers have been the public face of the fight against climate change, gathering at United Nations summit meetings and pressuring each other to reduce emissions. The results have often been lackluster. A climate conference in California this week tried something different. The meeting, organized by the state’s governor, Jerry Brown, had far fewer national leaders present. Instead, an array of governors, mayors and business executives from around the globe met to promote their successes in cutting greenhouse gas emissions locally and to encourage one another to do more.
This has been a big week for advocates who fight climate change. Business leaders, mayors, governors and activists from around the world rallied in San Francisco at the Global Climate Action Summit to advance their agenda in the face of a defiant White House.
California Gov. Jerry Brown issued an order Monday announcing the goal to eliminate carbon emissions in the state within 27 years. He also just signed a bill into law, making the state’s electricity completely emissions-free by 2045. Brown signed as the White House reportedly enacted another policy to stymie such efforts, this time by relaxing methane emission regulations.
For advocates pressuring big pension funds, companies and investment firms to deploy their money with the environment in mind, a good return looks to be the best motivator.
California Gov. Jerry Brown has made renewable energy and climate change a centerpiece of his final term, which ends in January. This week, he co-hosts the “Global Climate Action Summit”in San Francisco. Thousands of scientists, political leaders, business representatives and celebrities from around the globe are arriving all week for the event, which is designed to continue momentum at local levels — despite indifference from the Trump administration — to expand renewable energy and reduce emissions of greenhouse gases that scientists say are warming the planet and leading to more wildfires, heat waves, droughts, floods and other problems. Brown discussed the issues in an interview with Paul Rogers, resources and environment writer for the Bay Area News Group.
This week corporate and civic leaders from around the world will gather in San Francisco for the Global Climate Action Summit. The effort was spearheaded by Gov. Jerry Brown to move the fight against global warming beyond the national commitments made in Paris nearly three years ago. “Look, it’s up to you and it’s up to me and tens of millions of other people to get it together to roll back the forces of carbonization,” says Brown in a promotional video for the summit.
Water Utility Managers in California are far from unified in their use of climate change science to guide decisions, according to a recent study from the University of California, Davis. And as a result, they may be putting water supplies at risk. The study’s authors were interested in finding out what was happening on the ground, right at the local utility level. They interviewed 61 water managers across the state, ultimately dividing them into three groups based on how they engage with climate information.
So here’s the good news: Despite fears to the contrary, California isn’t facing a year-round drought in our warming new world. However, UC Riverside Earth Sciences Professor Robert Allen’s research indicates that what precipitation the state does get will be pretty much limited to the winter months—think deluge-type rainfall rather than snow—and non-winter months will be even dryer than usual, with little or no rain at all. “It is good news,” Allen said. “But only relative to the alternative of no rain at all.”
California officials are trying to solve a stinky mystery: A die-off has left hundreds of fish floating in a recently restored lagoon on the tony Malibu coast. Scientists believe the Malibu Lagoon die-off, which began last week, is likely caused by unusually warm water temperatures, said Craig Sap, superintendent of California State Parks’ Angeles District. “We had many days in a row of warmer-than-usual temperatures. We hadn’t had much of a breeze down there to keep the temperatures down,” Sap said Monday.
Heat waves will grow more severe and persistent, shortening the lives of thousands of Californians. Wildfires will burn more of the state’s forests. The ocean will rise higher and faster, exposing California to billions in damage along the coast. These are some of the threats California will face from climate change in coming decades, according to a new statewide assessment released Monday by the California Natural Resources Agency.
