SANTA CRUZ, Calif. — Wildfires that have claimed at least five lives and forced tens of thousands of people from their homes continue to blaze around California.Three major collections of fires are threatening tens of thousands of homes in the San Francisco Bay Area and central California.According to CNN, Vacaville — a city located between Sacramento and the Bay Area — is among the cities hardest hit by the wildfires.More evacuations are expected as hot and gusty weather continues into Friday.Daniel Berlant, the assistant deputy director of Cal Fire, says that the 22 major wildfires that are currently burning have burned more than 600,000 acres of forest.Officials believe that most of the wildfires were started by lightning and have been exacerbated by a historic heatwave and dry conditions.It wasn’t immediately clear whether the fatalities included a Pacific Gas & Electric utility worker who was found dead Wednesday in a vehicle in the Vacaville area. Also, in central California, a pilot on a water-dropping mission in western Fresno County died Wednesday morning when his helicopter crashed. At least two other people were missing and more than 30 civilians and firefighters have been injured, authorities said.CNN reports that wildfires have caused more death and destruction so far in 2020 than in all of 2019 combined. 1351

SAN YSIDRO, Calif. (KGTV) - Customs and Border Protection closed three lanes of traffic heading into the United States from Mexico Tuesday morning.In a statement, CBP said it was “to install and pre-position port hardening infrastructure equipment in preparation for the migrant caravan.”One lane of traffic was also closed at the Otay Mesa port of entry.It comes as active-duty troops have been working to add barricades and fencing as part of “Operation Secure Line.”On Tuesday, troops could be seen moving barriers covered with barbed wire along the border, periodically closing the southbound lanes into Mexico.In their statement, CBP officials warned “persons traveling northbound to the U.S. anticipate possible increased wait times because of the lane closures.”Even before the lanes were closed, wait times of six to seven hours had been reported at peak times in the standard lanes. Part of that was due to traffic control by authorities on the Mexican side.Travel as a pedestrian, however, has not appeared to be affected.Rebecca Fodor walked across Tuesday night and said it only took a few minutes. She said she did notice armed troops in camouflage uniforms.“It didn’t really change anything. I think they were just watching for anything suspicious,” she said.The lane closures will remain in effect indefinitely. CBP says reopening “is not anticipated to take place until sometime after people in the caravan arrive to the border.”  1469

SANFORD, Fla. — You've surely heard of the K-9 unit utilized by law enforcement agencies across the nation, but it was cows that came to the aid of one Florida police department Sunday.Sanford Police was after two suspects who crashed a stolen car, bailed out and ran.  282

SARASOTA Co., Fla. — A brawl between two moms at a school bus stop landed both in the hospital.One of those mothers was Tiffani Cruz. She was recently released from the hospital.“It was self-defense over an incident that made no sense," she said.While North Port Police say it started over an argument about parenting, Cruz claims she and the other mother have had issues before. She says two weeks ago, she confronted that mom for yelling at another child at the bus stop. But Tuesday morning, their verbal arguments went too far.“My heart was racing!” said Eithan Cruz, who is of no relation to Tiffani Cruz. The child and his brother, Bairon Velazquez, witnessed the fight from the back window of their school bus.“Her face was bleeding and stuff,” Eithan said.“I looked away," Bairon said..Cruz admits she hit the other mom with her mug. Police have not identified the other woman. “I went to run and that’s when she picked up the glass, ran at me and stabbed me twice in my arm, once at my wrist and in back of my shoulder," Cruz said.Both parents ended up in the hospital, but paramedics airlifted the other woman to the hospital with a serious cut to her throat.“She got this close to my face nudged me with her nose and when she nudged me with her nose— it was her fist going up so my fist was going up," Cruz said when asked why she felt she acted in self-defense.Sarasota County Schools is offering counselors after several dozen elementary-aged students witnessed the violent fight.“I regret the whole incident, there’s no reason it should have happened. We’re adults," Cruz said.Investigators say charges are pending.  1678

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
