Heavy rain this week could help quench the Camp Fire burning in Northern California, bringing with it an end to the threat of more wildfires this year but also new dangers.The rain will end "fire concerns for the winter," Robert Baruffaldi, a meteorologist in the National Weather Service's Sacramento office, told CNN Monday night.However, officials in Butte County are warning residents already devastated by the deadliest and most destructive wildfire in the state's history that rain arriving Wednesday could cause flash flooding and mudflows. The Camp Fire has killed 79 people, 64 of whom authorities have tentatively identified.The National Weather Service has issued a flash flood watch from Wednesday through Friday for the Camp Fire area. 756

Hot weather can increase the risk of natural disasters like droughts and wildfires, now, there is evidence extreme heat can increase harmful chemicals in the air.A study published recently in Science Advances looked at asphalt under different temperature conditions.“A main finding is that asphalt-related products emit substantial and diverse mixtures of organic compounds into the air, with a strong dependence on temperature and other environmental conditions,” says Peeyush Khare, a Yale chemical and environmental engineer and the lead author of the study, in a statement.The researchers took real-world samples of fresh road asphalt and put them in a controlled furnace with purified air. They heated the samples to temperatures between 104 and 392 degrees Fahrenheit, and measured the chemical components in the air.Total emissions nearly doubled when temperatures went from 104 to 140 degrees. At 104 degrees, 94 percent of the emissions measured were hydrocarbons.The group also exposed the asphalt samples to replicated solar heat, including UVA and UVB wavelengths, and found the rate of emission of potentially harmful chemicals increased. Showing that not only heat, but also solar radiation contributed to asphalt producing air pollution.Paved surfaces and roofs make up approximately 45% and 20% of surfaces in U.S. cities, respectively.Asphalt can be quite a bit hotter than the air around it, getting about 40 to 60 degrees warmer than the recorded air temperature.The researchers concluded that while policies and regulations have been put in place about car emissions and other forms of air pollution, asphalt should not be overlooked as a contributor.“It's another important non-combustion source of emissions that contributes to SOA (secondary organic aerosol) production, among a class of sources that scientists in the field are actively working to constrain better,” Drew Gentner, associate professor of chemical & environmental engineering, said. 1983

Hillsborough County (Florida) Sheriff's Office has released video record on May 30 that shows hundreds of looters breaking into a Tampa Walmart.Deputies are asking for the public's help to find some of the suspects who they say stole more than 0,000 in merchandise.It happened on Saturday, May 30, 2020, at 9:10 p.m. Authorities say a crowd gathered in front of a Walmart in Tampa. The store was closed due to the protests occurring outside the University Mall.People wielding blunt objects, like hammers, broke the glass entrance doors and stormed into the store.After reviewing surveillance video, detectives believe about 200 people entered the store and most began looting the electronics section. An estimated 6,000 in merchandise and damages was reported."Not only is this violence completely unacceptable, it was disrespectful to the protesters who were out there that night trying to express their message in an impactful way," said Sheriff Chad Chronister. "We are actively working to identify each and every one of these suspects and ask the public to provide any information they may have." 1115

George Floyd, the man who died in the custody of the Minneapolis Police Department in late May and whose death has sparked a nationwide protest movement against police brutality, was buried in Pearland, Texas, Tuesday following a private funeral.The funeral took place at The Fountain of Praise Church in Houston. It was livestreamed online and carried live by several news networks. Memorial services for Floyd have already been held in Minneapolis, the city where he lived his final years, and in North Carolina, the state in which he was born. Floyd lived the majority of his life in Houston.WATCH REPLAY"Tuesday's funeral followed a public viewing, which was held on Monday afternoon and evening.On May 25, Floyd was arrested after he allegedly attempted to use a counterfeit bill to buy tobacco at a Minneapolis convenience store. Officers later found him in a car, which was still parked outside the store. Police have said Floyd was under the influence of drugs or alcohol at the time.Officers pulled Floyd out of the car and handcuffed him. As they restrained him, bystander video shows one police officer, Derek Chauvin, kneeling on Floyd's neck for more than eight minutes as Floyd yelled he couldn't breathe. Chauvin continued to kneel on Floyd's neck for several minutes, even after he became unresponsive.The bystander video quickly went viral, prompting a wave of outrage. Protests in Floyd's name have drawn thousands of demonstrators in dozens of major cities around the world for more than a week, calling for a change in policing, diverting funds for police to other social programs and an end to systemic racism. 1643

GameStop announced this week that an additional 400 to 450 locations would close across the country by the end of 2020.While more video games are available for digital downloads, the next generation PS5 and Xbox will contain disc drives. The company was concerned that the next generation models would be digital only.Already in the last year, GameStop has closed 388 locations, shrinking its current retail footprint to 5,192 locations.“This will allow us to more efficiently and profitably service our customers,” company CEO George Sherman said about the closures.While many retailers have been shrinking their footprints as customers change their buying habits, GameStop is also encountering a change in technology in recent years, which has allowed customers to purchase games online.But GameStop says that there are some customers who prefer a physical disc, and that large video game downloads can use up internet data.“We believe the actions we are taking to optimize the core operations of our business by increasing efficiencies and creating a frictionless digital ecosystem to serve our customers, wherever and whenever they choose to shop, are enabling us to navigate the COVID-19 environment while positioning us well for the launch of the next generation of consoles,” Sherman said.GameStop saw a 26.7% drop in Quarter 2 sales in 2020 compared to 2019. 1374
