LA JOLLA, Calif. (KGTV) - Scientists at the Scripps Institution of Oceanography say atmospheric rivers will be the main source of California's rainfall over the next 80 years.The study, released Tuesday morning, says that could lead to more flooding, more drought and longer wildfire seasons."This region is becoming more sub-tropical and the dry season is expanding," says Alexander Gershunov, a research meteorologist at Scripps. "That is the case with all of the Mediterranean climate regions around the world."Right now, the study says California gets 40-50% of its annual rainfall from atmospheric rivers. Those are long, drawn out rain events that last for days. San Diego experienced several of them this past winter, leading to record rainfall.RELATED: Atmospheric river triggers evacuations in Southern California"These are warm storms," says Gershunov. "The mountains squeeze the rain out of them.""In California, most of the floods, historically, are associated with atmospheric rivers," says Gershunov. "So stronger atmospheric rivers definitely means more floods."RELATED: Scripps Institute uses Air Force to track atmospheric riversThe study says the dry periods between the storms will also be longer, leading to more dead brush and drought-like conditions. That could raise the likelihood of brush fires extending well into the winter.RELATED: UC San Diego creates ranking system for atmospheric riversThe study looked at atmospheric river data from the last 70 years and also predictive models for the next 80 years. Gershunov says this new information means the state will need to increase the amount and type of tools we use to manager water."This is really talking about decades into the future," he says. "These are the kind of time scales we need to understand to envision what the future of water resource management will look like." 1865

Laboratories across the U.S. are buckling under a surge of coronavirus tests, creating long processing delays that experts say are undercutting the pandemic response.With the U.S. tally of confirmed infections at nearly 4 million Wednesday and new cases surging, the bottlenecks are creating problems for workers kept off the job while awaiting results, nursing homes struggling to keep the virus out and for the labs themselves as they deal with a crushing workload.Some labs are taking weeks to return COVID-19 results, exacerbating fears that people without symptoms could be spreading the virus if they don’t isolate while they wait.“There’s been this obsession with, ‘How many tests are we doing per day?’” said Dr. Tom Frieden, former director of the Centers for Disease Control and Prevention. “The question is how many tests are being done with results coming back within a day, where the individual tested is promptly isolated and their contacts are promptly warned.”Frieden and other public health experts have called on states to publicly report testing turnaround times, calling it an essential metric to measure progress against the virus.The testing lags in the U.S. come as the number of people confirmed to be infected worldwide passed a staggering 15 million, according to data compiled by Johns Hopkins University. The U.S. leads the world in cases as well as deaths, which have exceeded 142,000.New York, once by far the U.S. leader in infections, has been surpassed by California, though that is partly due to robust testing in a state with more than twice the population of New York.Guidelines issued by the CDC recommend that states lifting virus restrictions have a testing turnaround time of under four days. The agency recently issued new recommendations against retesting most COVID-19 patients to confirm they have recovered.“It’s clogging up the system,” Adm. Brett Giroir, assistant health secretary, told reporters last week.Zachrey Warner knows it all too well.The 30-year-old waiter from Columbus, Ohio, was sent home from work on July 5 with a high fever a few days after he began feeling ill. He went for a test five days later at the request of his employer.Almost two weeks and one missed pay period later, he finally got his answer Wednesday: negative.Though Warner said most symptoms — including fever, diarrhea, chest tightness and body aches — stopped a few days after he was tested, he wasn’t allowed to return to work without the result.It was “frustrating that I’ve missed so much work due to testing taking forever,” Warner said. “It is what it is ... (but) I’m glad I’m negative and happy to be able to get back to work this week.”Beyond the economic hurt the testing lags can cause, they pose major health risks, too.In Florida, which reported 9,785 new cases and a rise in the death toll to nearly 5,500, nursing homes have been under an order to test all employees every two weeks. But long delays for results have some questioning the point.Jay Solomon, CEO of Aviva in Sarasota, a senior community with a nursing home and assisted living facility, said results were taking up to 10 days to come back.“It’s almost like, what are we accomplishing in that time?” Solomon said. “If that person is not quarantined in that 7-10 days, are they spreading without realizing it?”Test results that come back after two or three days are nearly worthless, many health experts say, because by then the window for tracing the person’s contacts to prevent additional infections has essentially closed.“The turnaround times, particularly across the South are too long,” Dr. Deborah Birx of the White House coronavirus task force said on Fox.Birx said the U.S. had shorter turnaround times in April, May and early June, but that “this surge and this degree of cases is so widespread compared to previously,” she said.Dr. Leana Wen, a public health professor at George Washington University said it’s reasonable to tell people awaiting test results to isolate for 24 hours, but the delays have been unacceptable.“Imagine you tell a parent with young children to self-isolate for 10 days or more without knowing they actually have COVID? I mean, that’s ridiculous. That’s actually absurd,” Wen said.U.S. officials have recently called for ramping up screening to include seemingly healthy Americans who may be unknowingly spreading the disease in their communities. But Quest Diagnostics, one of the nation’s largest testing chains, said it can’t keep up with demand and most patients will face waits of a week or longer for results.Quest has urged health care providers to cut down on tests from low-priority individuals, such as those without symptoms or any contact with someone who has tested positive.As testing has expanded, so have mask orders and other measures aimed at keeping infections down. Ohio, Indiana, Minnesota and Oregon became the latest to announce statewide mandatory mask orders Wednesday.The U.S. is testing over 700,000 people per day, up from less than 100,000 in March. Trump administration officials point out that roughly half of U.S. tests are performed on rapid systems that give results in about 15 minutes or in hospitals, which typically process tests in about 24 hours. But last month, that still left some 9 million tests going through laboratories, which have been plagued by limited chemicals, machines and kits to develop COVID-19 tests.There is no scientific consensus on the rate of testing needed to control the virus in the U.S., but experts have recommended for months that the U.S. test at least 1 million to 3 million people daily.Health experts assembled by the Rockefeller Foundation said last week that the U.S. should scale up to testing 30 million Americans per week by the fall, when school reopenings and flu season are expected to further exacerbate the virus’s spread. The group acknowledged that will not be possible with the lab-based testing system.The National Institutes of Health has set up a “shark tank” competition to quickly identify promising rapid tests and has received more than 600 applications. The goal is to have new testing options in mass production by the fall.Until then, the backbone of U.S. testing remains at several hundred labs with high-capacity machines capable of processing thousands of samples per day. Many say they could be processing far more tests if not for global shortages of testing chemicals and other materials.Dr. Bobbi Pritt of the Mayo Clinic in Rochester, Minnesota, says the hospital’s machines are running at just 20% capacity. Lab technicians run seven different COVID-19 testing formats, switching back and forth depending on the availability of supplies.At Emory University Hospital in Atlanta, lab workers lobby testing manufacturers on a weekly basis to provide more kits, chemicals and other materials.“There’s no planning ahead, we just do as many as we can and cross our fingers that we’ll get more,” said Dr. Colleen Kraft, who heads the hospital’s testing lab.___This story has been corrected to show that the CDC has issued guidelines recommending against repeat testing for patients recovering from coronavirus.___Webber reported from Fenton, Michigan, and Sedensky reported from Philadelphia.

LAUSANNE, Switzerland — Breakdancing has been confirmed as an official Olympic sport. The International Olympic Committee’s pursuit of urban events to lure a younger audience saw street dance battles officially added to the medal events program at the 2024 Paris Games. The IOC executive board also confirmed skateboarding, sport climbing and surfing for Paris. Those three sports will make their Olympic debuts at the Tokyo Games which were postponed because of the coronavirus pandemic. Ahead of the announcement, International Olympic Committee president Thomas Bach praised the additions, describing them during an interview in 2019 as events that will make the Summer Games "more gender balanced, more youthful and more urban."Breaking, the preferred term by those who practice breakdancing, actual made its Olympic debut already. It was part of the 2018 Summer Youth Games in Buenos Aires. The Tokyo opening ceremony is July 23, 2021. Paris organizers need time to prepare and so the IOC kept its schedule to confirm the 2024 sports this month. 1058

Last week's disturbance at Fox News host Tucker Carlson's home remains under investigation by the Metropolitan Police Department in Washington, D.C.A group of left-wing activists showed up, held signs criticizing Carlson, and shouted threats. Someone spray-painted an anarchy symbol on the driveway. The protest has been widely condemned by many members of the media, including multiple anchors at CNN.But one detail from the November 7 disturbance has come under scrutiny. Carlson told the Washington Post that "someone started throwing himself against the front door and actually cracked the front door."Liberal critics of Carlson have cast doubt on that claim by saying there was no evidence of damage to the door. They have accused him of lying and exaggerating to score political points.CNN contacted the D.C. police and asked about the door. The police report about the incident did not mention any damage on the door. Was there any sign that it was cracked, as Carlson claimed?A police spokeswoman responded, "MPD did not observe any visible damage to the front door of the victim's house the night of the incident."It is still possible that the door was cracked. And there is no doubt that the overall incident was disturbing to the Carlsons. While Tucker was at work when the activists showed up, his wife Susan was home alone. She called the police when she heard "loud banging and pounding on her front door," according to the police report.In videos uploaded to Twitter by the group, which calls itself an "anti-fascist" or Antifa group in DC, last Wednesday, protesters were heard saying "Tucker Carlson, we will fight! We know where you sleep at night!" They called him a "racist scumbag" and hurled epithets.The police, speaking of the incident, said "a group of protestors broke the law by defacing private property."But the disputed detail about the door has come up several times. Carlson's friend and business partner Neil Patel repeated the description on CNN's "Reliable Sources" last weekend."People start pounding on her door and throwing themselves at the door to the point where the door actually cracked," he said.President Trump talked about it in a Wednesday interview with the conservative site The Daily Caller, which Carlson and Patel co-founded.The interviewer said: "They cracked the door — what is this violence? Where does it come from? Do you have a message for Tucker and his family?""I do," Trump said, "I spoke to Tucker and I think Tucker's a great guy and I think it's terrible, they were actually trying to break down the door."The group defended its decision to show up at Carlson's home. They believe Carlson supports and promotes a white nationalist agenda on Fox News, a charge Carlson denies.After many journalists and commentators came to Carlson's defense last week, arguing that a person's family and home should not be targeted, some of Carlson's detractors pushed back by pointing to discrepancies in the accounts.Alan Pyke, a reporter for the liberal site ThinkProgress, wrote a first-person account of the protest and said one protester knocked firmly on Carlson's front door "three times," but then rejoined the rest of the group in the street. "This person did not throw their body against the door, as Carlson has claimed to newspapers," Pyke wrote.The Washington Post's Erik Wemple wrote Thursday, "the search for corroborating evidence continues." He noted that when he visited Carlson's home with a colleague one day after the disturbance, the door "seemed sturdy and fully intact. A woman who answered a knock looked it up and down and appeared to conclude it was in fine shape. It appeared to close snugly."Carlson responded angrily to Wemple's inquiries. And he responded angrily when contacted by CNN about the police's statement that officers did not observe any visible damage to the door."CNN has repeatedly defended Antifa, and you are doing it again now," he said in a statement through Fox News. "Your story is a disgusting attempt to minimize an attack on my family and bring more pain to my wife and four children. I'm not playing along. I hope you're ashamed of yourself. You should be."The D.C. police said last week that they are investigating the incident, given the defacing of private property that occurred.On Thursday, the MPD spokeswoman said "there is no further information to provide as this case remains under investigation. There have been no arrests made." 4511

LAS VEGAS — A Las Vegas family is living in fear after two men broke in while their teenage daughter hid in a bedroom closet.17-year-old Maxeen is still shook up after what happened inside her home near Cactus and Interstate 15 on Saturday.“It sucks to just be alone and I’ve never been in a situation like that,” she said.Maxeen said she was home alone Saturday when someone started ringing the doorbell repeatedly around 2:30 p.m.Maxeen felt something was wrong, and that’s when she says a man showed up in the backyard breaking in through the sliding glass door.“I tried to call my mom but she was at work, so I kind of ran upstairs and I knew he was going to come to the back,” the teen said.Maxeen dialed 911 and hid in one of the closets in a bedroom.The home’s interior surveillance camera shows two men running up the stairs where Maxeen was hiding.Maxeen’s mom is thankful her daughter is OK, but says this frightening ordeal has hit the entire family.“We’re very disturbed right now,” Maxeen's mother, Barbara, said. “It feels like it’s not real, but it is. So we got affected by it and everyone is so scared.”The family said the burglars actually left their getaway ride outside the home when they left.They took a picture of it and hope that vehicle will lead police to the two.  1309
