SAN FRANCISCO (AP) — The amount of snow blanketing the Sierra Nevada is even larger than the 2017 snowpack that pulled the state out of a five-year drought, California water officials said.As of Thursday, the snowpack measured 202% of average after a barrage of storms throughout winter and spring, according to the Department of Water Resources.The wet weather has slowed but not stopped, with thunderstorms prompting flash flood warnings Sunday in the central and southern parts of the state.At this time last year, the snowpack measured 6% of average — making this year 33 times bigger than 2018, the San Francisco Chronicle reported.In 2017, the snowpack measured 190% of average.The snowpack supplies about 30 percent of state water needs.In the Tahoe Basin, Squaw Valley ski resort has seen so much snow it plans to keep its slopes open until least July 5. In May alone, Squaw recorded 37 inches (94 centimeters).State officials consider the most important snowpack measurement to be the one taken around April 1 because that's typically when storm activity subsides."And then after that the sun's highest position in the sky contributes to rapid melting. This year, that didn't happen and we had late season snow," National Weather Service forecaster Idamis Del Valle told the newspaper.This year's April 1 reading put the snowpack at 176% of average, making it the fifth-largest on that date, with records going back to 1950, the Chronicle said.___Information from: San Francisco Chronicle, http://www.sfgate.com 1528

Scientists at the University of Nevada, Reno School of Medicine (UNR Med), led by its Nevada State Public Health Laboratory (NSPHL) are studying a likely case of COVID-19 reinfection.Forty-eight days after testing positive for SARS-CoV-2 in April 2020 and after testing negative consecutively twice, a Washoe County, Nevada patient tested positive again, in June.The patient had tested negative on two separate occasions in the interim. The genomes of the patient’s virus samples were sequenced in April and June, displaying significant genetic discordance between the two cases, implying the patient was infected twice.“We examined the genomic material of the viruses and samples to investigate this, says NSPHL Director Mark Pandori. “It is just one finding, but it shows that a person can possibly become infected with SARS-CoV-2 a second time.”To solidify confidence in the case, Pandori and the research team partnered with the Washoe County Sheriff’s Office Biology Unit to conduct identity testing on the specimens and lab samples evaluated in the study to verify the specimens were from the same person.Embedded in the genomic material of SARS-CoV-2 is a detailed code that Pandori says may provide insight to a better understanding of this virus.“A virus has a biological genome like all living things. Since March, the NSPHL has analyzed the genomic RNA of approximately 200 positive COVID-19 samples from Nevadans who have tested positive for COVID-19,” said Pandori. “The power of genomic information could turn the tables in the fight against the coronavirus.” The information is shared to a world-wide database known as “GISAID”,” alongside the work of thousands of researchers.According to Pandori and the NSPHL-led research team, reinfection cases are a potential warning sign that it is possible to catch COVID-19 more than once, and with unpredictable severity.“If reinfection is possible on such a short timeline, there may be implications for the efficacy of vaccines developed to fight the disease. It may also have implications for herd immunity,” says Pandori. “It is important to note, that this is a singular finding. It does not provide any information to us with regard to the generalizability of this phenomenon.”Herd immunity depends on the theory that after natural infection, our immune systems will collectively protect us as a community from reinfection and further spread. There are currently many more unknowns than knowns about immune responses to COVID-19. “After one recover from COVID-19, we still do not know how much immunity is built up, how long it may last, or how well antibodies play a role in protection against reinfection,” says Pandori.”While research and scientific advancements continue to build, Pandori says the hard work of fighting this pandemic together will continue through the use of facial coverings, hand-washing, social distancing, as well as wide-scale testing, contact tracing, and isolation of new cases.“This is a novel disease. We still have a steep learning curve ahead and lots of work to do, especially as inconvenient truths arise,” says Pandori.The NSPHL team are publishing their COVID-19 reinfection findings. Their report is publicly accessible on the SSRN preprint server, at https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3681489. This story was first reported by KTNV in Las Vegas, Nevada. 3384

SEDGWICK, Colo. – A man suspected of killing three members of a Kentucky family who were found dead Monday was arrested Monday afternoon near a small town in northeast Colorado.Edward Siddens, was arrested around 4:20 p.m. in Sedgwick, Colorado, which is just south and west of borders with Nebraska.He was wanted by Kentucky State Police out of Allen County, Kentucky. In connection to the deaths of Jimmy Siddens, his wife, Helen Siddens, and their son, Jimmy Siddens II. It's unclear how Edward Siddens might be related to the deceased.According to Kentucky authorities and local media reports, a county water employee was checking the family’s meter Monday and found two bodies on the ground. Authorities found another body nearby.The Sedgwick County Sheriff’s Office says it was notified shortly after 4 p.m. Monday that Siddens as in the county.Siddens was believed to have been driving a stolen vehicle when he was found by deputies in the town of Sedgwick. The sheriff’s office says deputies were involved in a “short low speed pursuit” with Siddens before he was arrested without incident.The sheriff’s office confirmed that Siddens was the man arrested Monday, and said it was working with Kentucky state police. Allen County is more than 1,000 miles away from Sedgwick. 1298

Scientists are proposing an ingenious but as-yet-unproven way to tackle climate change: spraying sun-dimming chemicals into the Earth's atmosphere.The research by scientists at Harvard and Yale universities, published in the journal Environmental Research Letters, proposes using a technique known as stratospheric aerosol injection, which they say could cut the rate of global warming in half.The technique would involve spraying large amounts of sulfate particles into the Earth's lower stratosphere at altitudes as high as 12 miles. The scientists propose delivering the sulfates with specially designed high-altitude aircraft, balloons or large naval-style guns.Despite the technology being undeveloped and with no existing aircraft suitable for adaptation, the researchers say that "developing a new, purpose-built tanker with substantial payload capabilities would neither be technologically difficult nor prohibitively expensive."They estimate the total cost of launching a hypothetical system in 15 years' time at around .5 billion, with running costs of .25 billion a year over a 15-year period.The report does, however, acknowledge that the technique is purely hypothetical."We make no judgment about the desirability of SAI," the report states. "We simply show that a hypothetical deployment program commencing 15 years hence, while both highly uncertain and ambitious, would indeed be technically possible from an engineering perspective. It would also be remarkably inexpensive."The researchers also acknowledge potential risks: coordination between multiple countries in both hemispheres would be required, and stratospheric aerosol injection techniques could jeopardize crop yields, lead to droughts or cause extreme weather.The proposals also don't address the issue of rising greenhouse gas emissions, which are a leading cause of global warming.And despite the conviction of the report's authors, other experts were skeptical."From the point of view of climate economics, solar radiation management is still a much worse solution than greenhouse gas emissions: more costly and much more risky over the long run," said Philippe Thalmann of the école Polytechnique Fédérale de Lausanne, an expert in the economics of climate change.David Archer of the Department of Geophysical Science at the University of Chicago said, "The problem with engineering climate in this way is that it's only a temporary Band-Aid covering a problem that will persist essentially forever, actually hundreds of thousands of years for fossil fuel CO2 to finally go away naturally."It will be tempting to continue to procrastinate on cleaning up our energy system, but we'd be leaving the planet on a form of life-support. If a future generation failed to pay their climate bill they would get all of our warming all at once." 2830

SANTEE, Calif. (CNS) - Gov. Gavin Newsom signed into law a bill authored by Sen. Brian Jones, R-Santee, which extends immunity from liability for local governments that operate skate parks, the lawmaker announced Tuesday.Senate Bill 1003 follows a similar bill Jones wrote in 2015 while he was a member of the Assembly that provided a four-year immunity window for municipally operated skate parks. SB 1003 makes that immunity permanent."Senate Bill 1003 grants much-needed immunity from liability for communities that operate skate parks," Jones said. "Local skateboarders and sport riders get a safer place than the streets to carve, do McTwists or ollies, and taxpayers are not going to be liable for the occasional mishap that is inherent to all active sports."SB 1003 was sponsored by the County of San Diego, and as an urgency measure, goes into effect immediately.The bill was co-authored by Sens. Pat Bates, R-Laguna Niguel, and Ben Hueso, D-San Diego -- who both also represent parts of San Diego County -- and Sen. Brian Dahle, R-Bieber. 1055
