SANTA CLARA, Calif. — The health officers in six San Francisco Bay Area counties are not waiting to reach a threshold recommended by the governor, and have issued a new stay-at-home order to take effect on Sunday. The changes, announced Friday, will last through Jan. 4. The counties have not yet reached Gov. Gavin Newsom’s threshold that requires a stay-at-home order when 85% of ICU beds at regional hospitals are full. But the health officers said the hospital system will be overwhelmed before the end of December, when Newsom’s order would apply to the Bay Area. "The dark COVID winter that we feared would come has arrived in the Bay Area," said Dr. Chris Farnitano, Contra Costa County health officer according to KGO. "I and other county health officers in the Bay Area don't think we can wait for the state's new restrictions to go into effect later this month. We must act swiftly to save as many lives as we can. This is an emergency."Restaurants, bars and wineries, and hair and nail salons will have to close, along with playgrounds. Restaurants would be able to do delivery or takeout. Retail stores can stay open, however they must lower capacity to 20%. Schools that have already received a waiver to reopen can stay open next week. All "critical infrastructure" can also remain open. Gatherings of any size are banned.The six counties include some of the most populous areas of the state, including Alameda County, Contra Costa County, San Francisco County and Santa Clara County. 1507

Scientists are warning that a domino effect will kick in if global temperatures rise more than 2 degrees Celsius above pre-industrial levels, leading to "hothouse" conditions and higher sea levels, making some areas on Earth uninhabitable.The report, "Trajectories of the Earth System in the Anthropocene," published Monday in the American Proceedings of the National Academy of Sciences, said "hothouse" temperatures could stabilize 4 degrees to 5 degrees Celsius (39 to 41 Fahrenheit) higher than pre-industrial levels."Human emissions of greenhouse gas are not the sole determinant of temperature on Earth. Our study suggests that human-induced global warming of 2 degrees Celsius may trigger other Earth system processes, often called 'feedbacks,' that can drive further warming -- even if we stop emitting greenhouse gases," lead author Will Steffen of the Australian National University said. 911

  

SAN ONOFRE (CNS) - The California Coastal Commission voted 10-0 in a special meeting Thursday to approve an inspection and maintenance program allowing Southern California Edison to store spent nuclear fuel in a storage site at the San Onofre Nuclear Generating Station.The program outlines actions SCE will take to inspect the canisters that contain spent nuclear fuel, as well as how potential issues with the canisters will be remedied.Robotic devices will be used to inspect the canisters and site conditions will be simulated on a test canister, which will be observed for potential degradation. Two spent fuel storage canisters will be inspected every five years starting in 2024, and the test canister will be inspected every two to three years.Canister flaws will be repaired by applying a nickel-based metallic spray, and the presence of flaws may result in increased canister inspection frequency and an increase in the number of canisters inspected.The inspection and maintenance program was also reviewed by the engineering consulting firm LPI, which provided recommendations that included the increase in canister inspections should flaws arise.Nearly 3.6 million pounds of spent nuclear fuel are stored at the plant, which stopped producing electricity in 2012.Concerns remain over the plant's proximity to the ocean and the potential for the site to be affected by rising sea levels, tsunami inundation, seismic hazards.By 2035, the commission may look to relocate the canisters to another site, although no such location is available, according to a commission report.The report states that though the commission "has consistently voiced its concern that there is no permanent or long-term repository for spent nuclear fuel from SONGS or the other nuclear power plants along the California coast," no such repository has been identified by the federal government, necessitating storage on-site at SONGS and many other nuclear power plants across the country.The inspection and maintenance program is designed to ensure the canisters "will remain in a physical condition sufficient to allow both on- site transfer and off-site transport," should such a site become available. 2198
