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

SANTA ANA (CNS) - A child who tested positive for West Nile Virus is the first person to be infected this year in Orange County, officials reported today.The child, whose age and identity are protected, was diagnosed sometime last week and was hospitalized but is expected to recover, according to the Orange County Health Care Agency. This was the first time this year a person in the county has been infected.The state has reported 10 people infected statewide so far in 2020. County officials said a total of seven people contracted West Nile in the area last year.One in five individuals infected with West Nile, for which there is no cure, will exhibit symptoms that include fever, headache, body aches, nausea or skin rash. The symptoms can last for several days to months.One in 150 people infected with the virus will require hospitalization. Severe symptoms include high fever, muscle weakness, neck stiffness, coma, paralysis and possibly death. Those at greatest risk include seniors and individuals with compromised immune systems.People older than 50 and who have underlying medical conditions are at a heightened risk.``The best way to avoid West Nile Virus infection is to take precautionary measures to avoid mosquito bites,'' said Dr. Clayton Chau, the director of the Orange County Health Care Agency and interim chief health officer for the county.To curb the spread of West Nile Virus, experts say it's critical to remove typical breeding grounds for mosquitoes that carry the disease. People should clean out standing water sources around the house, including pet bowls and flower pots. Stagnant swimming pools should be reported to authorities.People also can protect against bites by making sure window screens can keep bugs out and by insect repellant containing CDC-recommended Picaridin, DEET, oil of lemon eucalyptus, or IR3535. Mosquito season in Southern California generally spans May to October. 1934

Security lines and close human interaction at airports could one day be a thing of the past.With the travel industry determined to get people flying again, experts say the motivation to innovate is in overdrive.Airports have a way of fueling anxiety; one misstep can send even the most seasoned travelers into new heights of annoyance.So, could it ever be an experience we actually look forward to? The airport industry certainly hopes so.Justin Erbaci, the CEO of Los Angeles World Airports, says the innovations that land in your airport are usually tested at LAX first.“We’re using this as a platform to push forward a lot of things we wanted to push through, but there wasn’t the interest or the buy-in from government agencies or the industry, or the willingness to invest in these types of solutions,” Erbaci explained.Now, the industry is hearing customer complaints loud and clear, looking to revolutionize the airport experience.“That’s the goal for us, is to allow people to come through the airport and not have to see anyone and be able to serve themselves throughout the whole process,” he said.The first leg of your next airport experience could include the following:A touchless kiosk you can operate with your smartphone to check-in to your flightChecking luggage? This self-service system takes your bags without the need for an agent“A lot of things that are standard today seemed crazy when we first heard about them,” Erbaci said.As far as security goes, long lines leading to a TSA agent could also go away. Instead, passengers could be screened with biometric facial recognition technology.It’s already a reality at Dubai International’s smart tunnel, which the government says gets travelers through passport control in 15 seconds.LAX has tested this technology with passengers boarding flights, so they don't have to pull out their boarding pass."Through surveys, we’ve done over the years…seen people are willing to consent to give up identity aspects to get through the process faster,” Erbaci said.And carry-on bags could be screened using remotely-operated X-ray machines.While a completely self-service experience is likely several years away, changes are being implemented now to improve TSA screenings.“We have new technology that has been rolled out at dozens of airports across the country that allows the traveler to insert their ID or scan their own passport,” said TSA spokesperson Lorie Dankers.Dankers says the agency is looking at innovations being used around the world.“They test to make sure they don’t compromise security in the airport environment,” she explained. “We look to those cutting-edge technologies to make sure we are on the forefront of that.“We can’t think we’re going to be able to recover from an unprecedented situation by using old methods and means. We have to change.” 2839

SANTEE, Calif. (KGTV) - Doorbell camera video of a coyote following a man on a dog walk in Santee may be another example of coyotes becoming more aggressive in the area.On Monday after 9 p.m. on a quiet residential street, Ring doorbell camera video captures a man walking his dog. Moments later, something emerges from the shadows. It a coyote, and it's in an hurry. The video posted on the Ring app is titled "Beware coyote chasing a man with dog." That's exactly what appears to be happening. In the video, the coyote runs down the street before cutting in the man's direction. It's not clear if the coyote did catch up to the man or dog.Last week, 10News reported on Michelle Cimmarrusti's morning walk with Presley, an 8-year-old Silky Terrier. It unfolded on Palm Glen Drive, about a half mile from the site of the newest video. Two coyotes emerged from a bush and attacking Presley, while he was on his leash. Presley lunged, snapping his collar. He and the coyotes would end in a condo complex, where Presley was killed.Presley was the second dog killed by a coyote in the neighborhood in the last few weeks. Experts say coyotes attacking a leashed dog is a sign they're getting more aggressive in an area, and less afraid of humans, whether is food scarcity or the unintentional feeding of coyotes. 1315

SAN FRANCISCO (AP) — She was a self-described "adrenaline junkie," and he took "wow-worthy photos" of the couple posing at the edge of cliffs and jumping from planes that appeared on social media and a travel blog that attracted thousands of followers.In one post at the Grand Canyon this spring, 30-year-old Meenakshi Moorthy even warned daredevils who try to snap selfies from dangerous heights: "Did you know that wind gusts can be FATAL???" The caption accompanies a photo of Moorthy sitting on the edge of the canyon's North Rim.The couple's latest trip turned out to be their last. Moorthy and her husband, Vishnu Viswanath, 29, who were Indian expats living in California, fell to their deaths in Yosemite National Park last week while taking a selfie, the man's brother said Tuesday.RELATED: Brother: Indian tourists died in Yosemite fall while taking a selfieThey set up their tripod near a ledge at a scenic overlook in the California park, Viswanath's brother, Jishnu Viswanath, told The Associated Press. Visitors saw the camera the next morning and alerted park rangers, who "used high-powered binoculars to find them and used helicopters to airlift the bodies," he said.Rangers found their bodies about 800 feet (245 meters) below Taft Point, where visitors can walk to the edge of a vertigo-inducing granite ledge that offers spectacular views of the Yosemite Valley below.Their thrill-seeking social media posts foreshadow the couple's link to the growing problem of selfie deaths.RELATED: 2 die after falling from?overlook?in Yosemite National ParkA study published this month in the Journal of Family Medicine and Primary Care said 259 people had died taking selfies between October 2011 and November 2017.The report, based on findings from researchers in India who scoured worldwide media reports, said the main causes of selfie deaths were drowning, usually involving people being washed away by waves or falling from a boat, followed by people killed while posing in front of a moving train, deaths involving falls from high places or while taking pictures with dangerous animals.More than 10 people have died at Yosemite this year, some from natural causes and others from falls, park spokesman Scott Gediman said.RELATED: Photographer finds mystery engagement couple in viral Yosemite photoMoorthy and Viswanath were born in India and had lived in the United States for a few years, most recently in the San Francisco Bay Area. Cisco India said Viswanath was a software engineer at the company's San Jose, California, headquarters in Silicon Valley.They graduated in 2010 from the College of Engineering, Chengannur, in the Alapuzha district of India's Kerala state, one of their professors, Nisha Kuruvilla, told AP. She said Moorthy and Viswanath were both good students who were fond of traveling and had married at a Hindu temple in Kerala in southern India four years ago.Moorthy described her and her husband as "travel obsessed" on their blog, "Holidays & Happily Ever Afters," which was taken down Tuesday. It was filled with photos of the couple in front of snowy peaks and on romantic trips across Europe, where they took selfies from a gondola in Venice, at the Leaning Tower of Pisa and at the Vatican.RELATED: More than 250 people around the world have died taking selfies since 2011Moorthy wanted to work full time as a travel blogger, her brother-in-law said. She described herself as a "quirky free spirit" and "an ardent adrenaline junkie — roller coasters and skydiving does not scare me," Viswanath said.She posed at the edge of the Grand Canyon wearing a Wonder Woman costume, writing, "A lot of us including yours truly is a fan of daredevilry attempts of standing at the edge of cliffs — and skyscrapers. But did you know that wind gust can be FATAL??? Is our life just worth one photo?"Her husband's Facebook cover photo shows the couple smiling, with arms around each other standing at a Grand Canyon precipice. "Living life on the edge," he wrote.RELATED: Teen dies after falling while taking?selfie?in Yosemite National ParkIn a post from July 2017, the couple celebrated their wedding anniversary by skydiving in Santa Barbara, California. Moorthy posted a video on Instagram that shows her in a T-shirt saying, "Gimme Danger," and flashing a thumbs-up as she jumps from the plane."I believe I can flyyy. I believe i can touch the skyyy," she wrote in the post. "Aaaand touch the sky I did from an effin' 18000 feet thanks to the unconditional love-ninja in my life, Vishnu, who literally took this year's anniversary surprise a notch 'higher' than last year's hot air ballooning adventure, by gifting this adrenaline junkie with one of the highest tandem skydives in the world!"She also blogged about depression. In a post from April, Moorthy apologized to readers for going silent and "disappearing for more than a year."RELATED: UCSD graduate dies after fall at Yosemite"Between battling the tightening tentacles of depression and blustering in the tempest of moving madness, I am afraid social media is taking a back seat??" she wrote.The couple's pictures indicated they liked to pose in scenic spots at sunset, which was the last time they were seen alive.In an eerie coincidence, another couple who hiked to Taft Point captured pictures of Moorthy prior to her fall, saying she appears in the background of two of their selfies.Sean Matteson said Moorthy stood out from the crowd enjoying sunset at the overlook because her hair was dyed bright pink. He said she made him a little nervous because she was close to the edge.RELATED: Hiker falls to his death during thunderstorm at Yosemite"She was very close to the edge, but it looked like she was enjoying herself," said Matteson of Oakland, California. "She gave me the willies. There aren't any railings. I was not about to get that close to the edge. But she seemed comfortable. She didn't seem like she was in distress or anything."The travel advice website MyYosemitePark.com posted a photo of Taft Point to illustrate its "bad selfies" list, warning tourists: "Don't pose on top of a huge granite drop-off." It added, "It would only take a loose rock or bad footing to plummet."Yosemite spokeswoman Jamie Richards said officials were investigating the deaths, which could take several days.In India, after a rash of selfie-related deaths, the Tourism Ministry in April asked state government officials to safeguard tourists by installing signs in areas where accidents had occurred declaring them "no-selfie zones." 6571
