Atmospheric rivers that hit California getting a boost from melting Arctic ice:  “The fast-melting ice in the Arctic may be the primary cause of extreme weather across the globe, including some of the most violent, damaging storms to hit the Bay Area and California, a Scripps Institution of Oceanography study has found.  The Scripps paper, published Monday in the journal Proceedings of the National Academy of Sciences, is the first definitive study of the links between melting polar ice and changing climatic conditions reaching to the tropics, a cause-and-effect relationship that scientists had plenty of evidence for but had never precisely documented to this extent. … ”  Read more from the San Francisco Chronicle here:  Atmospheric rivers that hit California getting a boost from melting Arctic ice

Another approach to the Sustainable Groundwater Management Act:  “It’s known as SGMA and it’s foreboding to many growers, but there’s better ways to think about it, according to Michael Franz who owns Franz Wholesale Nursery, along with his brother in the town of Hickman, Stanislaw County. He also sits on the Board of the Turlock Irrigation District, which delivers water to thousands of acres of almonds and walnuts.  “SGMA is a really tough conversation,” said Franz. ... ”  Read more from Ag Info here: 🔓 Another approach to the Sustainable Groundwater Management Act

Governor’s budget addresses growing wildfire risks:  “In recent years, California has experienced some of the worst wildfires on record, and the risk is increasing as the climate warms and precipitation becomes more variable. Governor Newsom’s proposed budget supports an array of tools for reducing the threat of wildfire. Funding for these investments would come from the state General Fund, a proposed climate resilience bond, and the greenhouse gas reduction fund (GGRF). The budget prioritizes three wildfire-related areas … ”  Read more from the PPIC here:  🔓 Governor’s budget addresses growing wildfire risks

California wildfire reality: new alert systems and forest management key as climate change continues:  “We’re living in the new California reality of catastrophic wildfires and weeks of forced power outages.  So, how did we get here?  A panel hosted by Operation Sierra Storm at South Lake Tahoe brought together leaders of Cal Fire’s new Wildfire Resilience Program, PG&E and the National Weather Service to discuss just that and what to expect in 2020. ... ”  Read more from NBC Bay Area here:  🔓 California wildfire reality: new alert systems and forest management key as climate change continues

Chevron Official Tells California Lawmakers Repairs Caused 2019 Oil Spill:  “A senior Chevron official told California lawmakers on Monday a 2019 incident that spilled over a million gallons of water and oil into a creek bed was likely caused by its attempts to patch up a shuttered well.    During an oversight hearing at the state Capitol, Billy Lacobie said the very thing Chevron was trying to prevent happened while the company was securing a previously abandoned well at its oilfield in Kern County. The head of operations at Chevron’s six California oilfields told lawmakers and state officials that the spill did not harm surrounding drinking water supplies or farms and had a minimal impact on wildlife. … ”  Read more from the Courthouse News Service here:  🔓 Chevron Official Tells California Lawmakers Repairs Caused 2019 Oil Spill

Study: Climate change threatens world’s wine supply:  “More than half of the areas around the world suitable for growing grapes used for wine could become unsuitable for the purpose in 80 years due to climate change, according to a new study.  A study published Monday in the National Academy of Sciences’ online journal said that 56 percent of wine-growing regions could be unsuitable by 2100 should the Earth’s climate warm 3.6 degrees Fahrenheit in that time. … ”  Read more from The Hill here:  🔓 Study: Climate change threatens world’s wine supply

The Pacific Ocean is so acidic that it’s dissolving Dungeness crabs’ shells:  “The Pacific Ocean is becoming more acidic, and the cash-crabs that live in its coastal waters are some of its first inhabitants to feel its effects.  The Dungeness crab is vital to commercial fisheries in the Pacific Northwest, but lower pH levels in its habitat are dissolving parts of its shell and damaging its sensory organs, a new study found.  Their injuries could impact coastal economies and forebode the obstacles in a changing sea. And while the results aren’t unexpected, the study’s authors said the damage to the crabs is premature: The acidity wasn’t predicted to damage the crabs this quickly. … ”  Read more from the San Jose Mercury News here:  The Pacific Ocean is so acidic that it’s dissolving Dungeness crabs’ shells

Critics question data used in rule replacing Obama-era waterway protections:  “Critics say the Environmental Protection Agency’s (EPA) water policy unveiled Thursday is one of the biggest rollbacks to water policy in decades, but it’s tough to know the extent of its impact because of challenges that come with mapping America’s waterways.  “I’ve never seen an EPA regulation so utterly divorced from the facts and so apparently uninterested in developing them,” said Jon Devine, the Natural Resources Defense Council’s director of federal water policy.  … ”  Read more from The Hill here: 🔓 Critics question data used in rule replacing Obama-era waterway protections

Trump’s USDA chief, unlike Trump, backed water efficiency:  “If President Trump wants to understand the risk of rolling back water efficiency standards that have been in place for almost 30 years, he can turn to a member of his own Cabinet.  Agriculture Secretary Sonny Perdue has signed off on regulations that treat water-efficient toilets and shower heads as effective tools to save Americans from droughts and other risks.  In 2007, when Perdue was Georgia’s governor, the state was in the grips of a historic and extreme drought, and Atlanta was months away from losing its primary water source. … ”  Read more from E&E News here:  🔓 Trump’s USDA chief, unlike Trump, backed water efficiency

California’s water department must face the reality of climate change and diverse needs, says Bill Dodd:  He writes, “As we enter a new decade, California faces increasing environmental challenges caused by climate change, creating an uncertain future for our water resources. We need bold leadership to address these impacts. It is time for California’s Department of Water Resources (DWR) to implement water policy for the state that shores up our precious waterways and diversifies water supplies in the face of these imminent threats.  Scientists have long cautioned about the plight of the San Francisco Bay-Delta estuary, the largest estuary on the West Coast, home to many important species, and hub of California’s major water diversion and delivery projects. Warnings detail how fish and wildlife will disappear due to mismanagement, and climate-driven impacts will increase droughts and reduce snowpack. … ”  Read more from the Sacramento Bee here: California’s water department must face the reality of climate change and diverse needs

Reversing history in the San Francisco Bay:  “Since the 19th century, close to 90 percent of the marshland that historically ringed San Francisco Bay has been lost to development. The effects of that loss include diminished wildlife habitat, increased flood risk, degraded water quality, and far fewer opportunities for nature-based recreation.  In 2016, more than two-thirds of voters across nine counties supported ballot Measure AA, a $12 per year parcel tax over 20 years to provide $500 million in restoration funding to reverse some of those effects.  Now, Measure AA funds administered through the State of California’s San Francisco Bay Restoration Authority are funding a range of wetland restoration, flood management and wildlife-oriented public recreation projects are blooming around the Bay, including on the area’s two largest National Wildlife Refuges managed by the U.S. Fish and Wildlife Service. … ”  Read more from the US FWS here: 🔓 Reversing history in the San Francisco Bay

San Diego v. MWD: There’s no water under the bridge in the feud that won’t end:  “Just days before Christmas, Mayor Kevin Faulconer became the first mayor since Jerry Sanders in 2012 to appear before the 36-member board of the San Diego County Water Authority.
