How low our expectations of government have sunk. Federal agencies now regularly deny science that explains the warming of our planet and rising seas. Back-room deals and obstruction of the public’s will have become so commonplace that we notice when one of our state government’s agencies takes action to protect the environment, even if it falls well short of the mark.
Every year, like a giant frozen reservoir, snow that falls across the Sierra Nevada mountain range slowly melts in spring and summer months, providing roughly one-third of the water supply for California’s cities and farms, from the Bay Area to Los Angeles. But at the current rate at which the climate is warming, the amount of runoff from Sierra snow into California’s largest reservoirs is heading for a dramatic decline — a 54 percent drop in the next 20 to 40 years and 79 percent in the next 60 to 80 years, according to a new study from scientists at Lawrence Berkeley National Laboratory.
For months, the Santa Clara Valley Water District has been preparing for its annual flood awareness campaign. Our multi-language poster full of flood safety tips is hitting mailboxes in areas located in or near flood-prone zones. You may hear or see our new flood awareness ads, with the theme “Climate Changed.” The timing of this message could not be more fitting. The newly released Fourth National Climate Assessment shows that the effects of climate change are already being felt all over the country, including more frequent and intense extreme weather and climate-related events.
As the Civil War raged, William Brewer, a young botanist from upstate New York, spent five years cataloging California’s natural attributes for its Legislature. As he and his crew traversed the state by mule in their annual sojourns, living off the land, Brewer found much to commend. But in letters to his brother, decades later assembled into a must-read book, “Up and Down California,” Brewer also wondered whether its climate would impede its development.
For the past week, California has been locked in a tense, daily mix of choking thick smoke and dangerously dry, windy fire-weather conditions. But an end might be around the corner. Meteorologists said Tuesday that two storm systems appear to be developing over the Pacific Ocean, with rain increasingly likely next week for most of the state. “It looks like the storm door is going to open,” said Jan Null, a meteorologist with Golden Gate Weather Services in Saratoga.
For all of his accomplishments, when it comes to water issues, Gov. Jerry Brown is leaving Gov.-elect Gavin Newsom with a mess. What’s needed is a paradigm shift — a change in the conversation that doesn’t pit Northern California vs. Southern California and environmentalists against farmers and urban dwellers. Consider: What if Newsom borrowed a page from Brown’s climate change playbook, which called for a big move away from coal and oil in favor of renewable and green energy?
The likelihood this winter of an El Niño — the weather pattern marked by warm Pacific Ocean waters that can affect California’s rainfall — is increasing. The probability of El Niño conditions being present by December is now 70 to 75 percent, up from 50 percent five months ago, according to a new report Thursday from the National Oceanic and Atmospheric Administration. But so far, this El Niño looks more like a lamb than a lion.
California voters may be feeling a sense of deja vu when they consider Proposition 3, an $8.9 billion water bond on the November ballot to fund a long list of water projects — from repairing Oroville Dam to restoring Bay Area wetlands to helping Central Valley farmers recharge depleted groundwater. Didn’t the voters recently approve a big water bond? Maybe two of them? Yes. And yes.
Barely a week past summer, some Sierra Nevada peaks have received a dusting of snow — and a bigger accumulation is possible this weekend. The unsettled weather and brisker-than-normal temperatures that have lingered in the Bay Area this week brought hail and snow to the higher elevations of the Lake Tahoe area. The National Weather Service’s Reno office said that another wave of precipitation Friday night and Saturday could see an accumulation of 1 to 2 inches of snow at the higher passes, such as Tioga and Sonora. The greatest chance of snow showers at Yosemite’s Tuolumne Meadows is after 11 p.m. Saturday, the weather service said.
After toiling away in the remote hills east of Interstate 680 on the Alameda-Santa Clara county line for seven years, hundreds of construction workers have finally finished the largest dam built in the Bay Area in 20 years. The 220-foot tall dam at Calaveras Reservoir — as high as the roadway on the Golden Gate Bridge soars above San Francisco Bay — replaces a dam of the same size, built in 1925. State dam inspectors flagged the older dam in 2001 as at risk of collapse in a major earthquake on the nearby Calaveras Fault. If it had failed, state officials estimated it could have sent a 30-foot wall of water into Fremont and neighboring communities, potentially killing thousands of people.
