GENEVA (AP) — The European Union’s Earth observation program says the ozone hole over Antarctica has swelled to its largest size and deepest level in years.Experts at the Copernicus Atmospheric Monitoring Service say a strong, stable and cold polar vortex has driven the expansion, and have called for greater international efforts to ensure countries abide by an international accord to phase out use of ozone-depleting chemicals.Vincent-Henri Peuch, who heads the service, said in a statement that the ozone hole was “definitely” among the largest in the last 15 years.“With the sunlight returning to the South Pole in the last weeks, we saw continued ozone depletion over the area,” Peuch said. “After the unusually small and short-lived ozone hole in 2019, which was driven by special meteorological conditions, we are registering a rather large one again this year, which confirms that we need to continue enforcing the Montreal Protocol banning emissions of ozone depleting chemicals.”Since the ban on halocarbons, officials say the ozone layer has slowly been recovering and data shows a trend in decreasing area of the ozone hole.Ozone depletion over the Antarctic continent was first noticed in 1985. 1217

GRASS VALLEY, Calif. (KGTV and AP) — The body of a woman found in a shallow Northern California grave may be an aspiring model and actress from Macedonia who vanished in Los Angeles last month, authorities said.The Nevada County Sheriff's Office said the body found Tuesday has not been identified. Los Angeles Police said they believe the remains are those of 25-year-old Adea Shabani, KABC reported. An autopsy is scheduled for Wednesday.Sheriff's Lt. Rob Bringolf said Los Angeles police detectives searching for Shabani led investigators to the grave 56 miles (90 kilometers) north of Sacramento. Shabani was last seen in Hollywood on Feb. 23.An acquaintance of Shabani's fatally shot himself in the head last week. The California Highway Patrol said 33-year-old Chris Spotz led officers on a Southern California vehicle pursuit that ended with his death in Riverside County. The CHP said Spotz was driving a stolen pickup. 950

Goldman Sachs' chief economist says if masks were required across the country, it could save the U.S. economy from a 5% loss.According to Forbes and CNBC, Jan Hatzius said in a note to clients that a nationwide mask requirement would prevent the spread of COVID-19 and prevent the need for further lockdown restrictions."We find that face masks are associated with significantly better coronavirus outcomes," Hatzius said. "Our baseline estimate is that a national mandate could raise the percentage of people who wear masks by 15 [percentage points] and cut the daily growth rate of confirmed cases by 1.0 [percentage point] to 0.6%. These calculations imply that a face mask mandate could potentially substitute for lockdowns that would otherwise subtract nearly 5% from GDP."According to the Bureau of Economic Analysis, the U.S. GDP totaled about .54 trillion in the First Quarter of 2020. According to Hatzius' analysis, not instituting a national mask requirement would cost the U.S. economy just over trillion.Several studies show that a mask or facial covering limits the wearer from spreading airborne droplets when speaking, sneezing or coughing. The coronavirus can live outside the body in these droplets for several hours and, in turn, infect other people — even before the person who spread the droplets has exhibited symptoms of COVID-19.Earlier this year, the Centers for Disease Control and Prevention (CDC) issued guidance that strongly recommended all Americans over the age of 2 wear masks in public, particularly in situations that would make social distancing impossible. However, it's stopped short of requiring masks.The CDC also says those who have trouble breathing should not wear a mask if it puts the wearers' health at risk.President Donald Trump has left individual states to issue mask requirements as they see fit, but has notably chafed at wearing face coverings during public appearances. He has also declined to require masks at his indoor rallies.About one-third of states across the country currently require masks when in public. Forty-six states require masks in certain instances. Presumptive Democratic Presidential Nominee Joe Biden has said he would make masks a requirement for the remainder of the pandemic should he be elected president. 2298
