SAN DIEGO, Calif. (KGTV) - An open letter to the World Health Organization titled “It is Time to Address Airborne Transmission of COVID-19” is signed by 239 scientists from 32 different countries and highlights the importance of acknowledging and protecting the public against the possibility that coronavirus can be spread through the air. One San Diego scientist who signed is from the UCSD Scripps Institution of Oceanography, Doctor Kim Prather.The idea shared is that COVID-19 can be spread from aerosols, which are particles that float in the air rather than dropping to the ground like a droplet. An infected person breathes out aerosols that are suspended in the air, then another person walks through that air and breathes it in.It’s no secret that heath officials have discussed the importance of good airflow to stop the spread, but this paper says leaders like the WHO are not recognizing the possibility that it is airborne and the “lack of clear recommendations on the control measures against the airborne virus will have significant consequences: people may think that they are fully protected by adhering to the current recommendations, but in fact, additional airborne interventions are needed for further reduction of infection risk.”Researchers say wearing masks and social distancing are important steps to stopping the spread, but want to also emphasize that other steps need to be taken to stop the spread through the air. Some steps for public places include getting better ventilation and decreases crowds. At home, people can open doors and windows and also use air purifiers to help. 1618

SAN DIEGO (KGTV) Chicano artists and activists gathered to voice their concerns about two more murals getting torn down during construction on a local school, one week after the first mural was destroyed.The San Diego Unified School District is working on upgrading Memorial Preparatory school in Logan Heights. Part of the upgrade involves tearing down buildings and walls, and on some of those walls are decades-old murals painted by local Chicano artists. The murals all celebrate the history and culture of the local area.Wednesday, Sept. 30, the artists gathered with a group outside the school and asked to save the murals. Moments later, the first mural was destroyed. A spokesperson for the district said that building could not be saved because it had asbestos.The advocates expressed concern over that statement, saying if the asbestos was really that bad, the construction workers should not have let it collapse the way it did, allowing dust to spread into neighboring homes.RELATED: Barrio Logan artists upset about destruction of historic muralOne week later and the artists gathered again in front of the school, this time saying there are two more murals inside the school they want to save. They said to their knowledge, the buildings these murals are painted on are staying up and these areas do not have asbestos, but certain parts are being torn down, including where the murals are. They’re asking the district to save these murals, offering to supply the funding and labor needed to move the artwork.“What we’re saying is we have the resources we have the will and we have the passion to go forward with the removal. So it’s not that it can’t be done, it’s that we’re not being allowed our rights to preserve them for the entire community,” a representative from the group said.KGTV spoke to a representative from the district Sept. 30, who said they did not want to take the murals down but had to for safety reasons due to the asbestos. They also mentioned the construction will benefit the students in the long run. The district could not be reached again the following week, so KGTV was unable to ask why the other two murals cannot be saved. 2176

SAN DIEGO (KGTV)— With the start of summer just days away, San Diego Gas and Electric (SDGE) is encouraging customers to take advantage of free programs that could potentially save a significant amount on their energy bills. 10News has reported on dozens of stories in which customers are outraged by unexpectedly high bills and surprise “High-Usage” fees. But SDGE says it does not have to be this way if customers switch to the “Level Pay” Option. “This is a really great way to avoid the high spike on your bill, let’s say in July or August,” SDGE Spokesman, Wes Jones said. For the “Level Pay” option, SDGE takes the average of the last 12 monthly bills and charges the customer the same amount for the next three months. This means there are no surprises during the summer months. “You are tapping into those months where you didn’t run your AC in February, so your bill is lower,” Jones said. “So this is a great solution for that type of customer that has that volatility throughout the year.”SDGE says another free money-saving option is to switch to the “Time-Of-Use” Plan. As long as the customer keeps track of when they use power, they can save money. Standard Summer Pricing:Tier 1: 0-130% use of baseline: SAN FRANCISCO (AP) — A firefighter who died while helping people evacuate a Northern California blaze was killed by a fire tornado that at one point reached a temperature of 2,700 degrees Fahrenheit (1,480 degrees Celsius), officials said.Redding firefighter Jeremy Stoke died after he was enveloped in seconds by a fire tornado with a diameter of 1,000 feet (300 meters) and winds up to 165 mph (265 kph), the California Department of Forestry and Fire Protection said in a report released Wednesday detailing his death and the death of a bulldozer operator.Videos released with the report show the massive blaze burning in a populated area and sending a cloud of thick smoke up into the air with flames swirling up into the sky.RELATED: Firefighter killed battling Mendocino Complex fire  The tornado ripped roofs off houses and flung power line towers, cars and a shipping container into the air near the spot where Stoke was overtaken by the flames, according to the report.Cal Fire officials said that on July 26, the 37-year-old fire inspector was driving his pickup truck down a Redding road, working on evacuating people. One minute later he radioed out a "mayday" call saying he was getting burned and needed help.Stoke "identified himself by his radio call sign, and stated that he needed a water drop and was getting burned over," the report said.When an engine captain tried to contact him shortly after, there was no response, it said."Observations from witnesses and other evidence suggest that either several fire tornadoes occurred at different locations and times, or one fire tornado formed and then periodically weakened and strengthened causing several separate damage areas," the report said.Stoke, whose remains were found the following day, was one of eight people killed since the blaze started on July 23 with a spark from a vehicle driving on a flat tire.RELATED: A flat tire started the deadly Carr Fire and days of devastation in California  The wildfire has destroyed nearly 1,100 homes. It was 71 percent contained as of Thursday.The report also detailed the death of private bulldozer operator Don Smith, 81, of Pollock Pines, who was killed when his bulldozer was caught in the flames while trying to improve a fire line, defending a home during what the officials say were "extraordinary fire weather conditions."Both deaths and the injuries occurred within an hour and 50 minutes in one 3-mile (5-kilometer) stretch.Smith was trying to improve a previously constructed a fire line near the Buckeye Water Treatment Plant outside Redding after 5 p.m. on July 26 when other firefighters noticed "a rapid increase in fire activity."It jumped the fire line and a Cal Fire crew chief said he made several radio attempts to tell Smith to "get out of there." Two firefighters in the area also "recognized the urgency of the situation" and tried to reach Smith on foot but had to turn back because of the encroaching flames.Smith reported that he was cut off by the fire and was pushing on in his 2002 John Deere open cab bulldozer in an attempt to reach a safe area. He also requested water drops and four helicopters began dropping water through the smoke and flames around Smith's last known location.Once the smoke cleared, a pilot saw that Smith's dozer had been engulfed in flames and there was no sign of the protective metallic tent that firefighters deploy as a desperate measure when they are about to be overrun by fire. After two attempts, a fire captain was able to reach the bulldozer two hours later and confirmed that Smith was dead. 3592.29 per kWhTier 2: 133-399% use of baseline: SAN DIEGO (KGTV)- Visitors and locals are expected to flock to San Diego beaches this Fourth of July weekend.While some beaches will close in California for the holiday weekend, San Diego County officials will keep local beaches open.San Diego County Supervisor Nathan Fletcher said no COVID-19 community outbreaks had been linked to beaches, and without the data, it would not make sense to close them off.According to Dr. Wilma Wooten, the county’s public health officer, leaders of San Diego’s coastal communities said they believe they can manage the enforcement of social distancing and facial coverings this weekend.Longtime Solana Beach residents Richard and Lori Brenckman are frustrated by the idea of crowds flocking to the beaches during a pandemic.“The general public has shown that it’s not trustworthy to social distance,” said Lori Brenckman. “They want to gather, and most people have proven that they won’t follow the rules.”Beachgoers are required to maintain social distancing and wear a facial covering when they come within six feet of someone not from the same household. Mixing with other groups is prohibited.Lifeguards across the county are preparing for the busy weekend.“It is the big holiday of the summer, so we expect giant crowds,” said Lifeguard Lt. Rick Romero with San Diego Fire-Rescue. “This a tourist destination; everyone wants to come to San Diego. It’s a great place to hang out.”Romero said extra lifeguards would be in place both Friday and Saturday. “We’re just asking people for some compliance, have some common sense, be nice to each other,” he said.Elevated surf and the possibility of dangerous rip currents are expected over the weekend.California Gov. Gavin Newsom also ordered parking facilities at all state beaches in Southern California, and the Bay area to close this weekend. 1839.39 per kWh*“High-Use” Charge: 400%+ use of baseline: <云转化_句子>.55 per kWhTime-Of-Use Summer Pricing: On Peak: 4pm-9pm Tier 1: 0-130% use of baseline: <云转化_句子>.46 per kWhTier 2: 133-399% use of baseline: <云转化_句子>.57 per kWhOff-Peak Hours: 6am-4pm AND 9pm-midnightTier 1: 0-130% use of baseline: <云转化_句子>.24 per kWhTier 2: 133-399% use of baseline: <云转化_句子>.35 per kWhSuper Off-Peak Hours: Midnight-6am Tier 1: 0-130% use of baseline: <云转化_句子>.19 per kWhTier 2: 133-399% use of baseline: <云转化_句子>.30 per kWhTime-Of-Use Pricing does not have the *“High-Use” Charge tier. SDGE recommends customers to take advantage of this to pre-cool their home during off-peak hours. “At noon, 1 pm, or 2 pm, crank up that AC,” Jones said. “Get that house nice and cool. And as it gets later in the day, adjust that thermostat.”If you use an AC, remember to change out your AC filter. That makes your machine run much more efficiently. And if you want to save even more money, try using the fan. “That is going to be about seven times cheaper than running a room AC unit,” Jones said. “So if you can stand using a fan for a few hours here and there as opposed to that room AC you’re going to save some money on your bill.”When all else fails, remember to get back to basics. Simple things like checking for window and door seals, and rolling down your sun shades can make a big difference. Customers can change their settings to the “Level Pay” Option and “Time-Of-Use” plan at any time for free at SDGE.com/LPP. 2734
