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

HIGHLANDS RANCH, Colo. – It’s been three months since a black student in Colorado reportedly punched a white student wearing a Nazi jacket in the face, but the incident has only come to light after a video of the fight went viral this week.The Denver Post reported Friday a Twitter user from Baltimore posted the video to his feed, which spread like wildfire on the social media website.The fight, which happened in August, began at lunch break in front of Mountain Vista High School in Highlands Ranch, Colorado, when the white student in the Nazi jacket was doing a T-pose, which is a popular meme among gamers to demonstrate dominance or power, said Lt. Lori Bronner with the Douglas County Sheriff’s Office.Historically, some members of the Ku Klux Klan have used the pose to “represent a burning cross,” Bronner told KMGH.Bronner said the black student saw the white student doing the T-pose and went up to confront him. They exchanged words and the black student spit on the white student, at which point the white student did the same to the black student.The black student then briefly walked away but returned to confront the white student once again before punching him in the face, causing the student to fall to the ground, according to Bronner.She said the student wearing the green Nazi jacket then got up, grabbed a rock and threw it at the black student, missing him.According to Bronner, the student who threw the punch then ran after his peer and kicked him after he fell to the ground. She said the student in the Nazi jacket curled into a protective, fetal position while calling the black teen a racial slur.Shortly afterward, a third student and staff members separated the two boys.“We’ve had no other situations like this,” said Bronner, adding this type of disputes are very rare.Bronner said the black student was charged with assault for punching and kicking the white student, and was also charged with harassment and disorderly conduct.The white student, Bronner said, was charged with harassment, disorderly conduct and criminal attempted assault for throwing a landscaping rock at the black student.No one was charged with a hate crime.KMGH reached out to Douglas County Schools for comment. Paula Hans, a public information officer for DCSD, said she could not discuss specifics on any given student’s disciplinary actions, only saying “a student is not allowed per DCSD dress code policy to wear anything that is offensive or disruptive to the learning environment.”When asked if the white student's jacket had any Nazi markings, Hans only said the principal at Mountain Vista High School informed her that there were "no markings on the jacket." According to the Denver Post, students said the white teenager was known for wearing the green jacket complete with Nazi regalia. A review by a newspaper reporter of the juvenile’s Instagram account shows multiples pictures of him wearing Nazi uniforms. 2966

Georgia's Republican Secretary of State says that despite voting for President Donald Trump and donating to his campaign, Trump threw him "under the bus" by attempting to overturn the results of the presidential election in the state.In an opinion piece for USA Today, Georgia Sec. of State Brad Raffensperger criticized Trump for refusing to "accept the facts" in narrowly losing the state to President-elect Joe Biden.In his opinion piece, Raffensperger noted that despite the circumstance, Georgia's elections went fairly smoothly, noting record numbers of mail-in and early voting and "minuscule" wait times on election day. But he said that all changed when Trump began publicly undermining trust in Georgia's elections."Elections are the bedrock of our democracy," Raffensperger wrote. "They need to be run fairly and, perhaps more important, impartially. That's not partisan. That's just American. Yet some don't seem to see it that way."As the head of elections in Georgia, Raffensperger has found himself at the center of attention since election day. Days after the polls closed, Raffensperger called for an unprecedented statewide audit of the presidential election in the state, which required a hand recount of election results.While the audit did find a few thousand votes for Trump that had not been previously counted, the new votes only represented a small change in the final tally. Georgia has certified its election, though the Trump campaign has filed for a machine recount of votes, which is unlikely to change the final tally.All the while, Trump has continued to cast doubt on the electoral process in the state — and Raffensperger says he's been personally pressured by fellow Republicans to find ways to exclude legally-cast ballots. He also says both he and his family have faced threats in the face of the recounts.In his piece, Raffensperger skewered both Republicans and Democrats who attempted to discredit the election process in the state."An onslaught of fake news and unrepentant disinformation threatened to tear the fabric of our country apart," he wrote. "People on both sides of the aisle generated controversies out of nowhere to stir up trouble."In particular, Raffensperger criticized Trump for "adopting the playbook" of Stacey Abrams, a Democratic gubernatorial candidate who lost out to Gov. Brian Kemp in 2018. Abrams never conceded to Kemp and only suspended her campaign after the state certified the results of the election.Raffensperger also went after Rep. Doug Collins, calling him a "failed sente candidate." Collins, who was eliminated from a Senate race this month, has been working with the Trump campaign in its efforts to overturn election results.Raffensperger closed his editorial by calling for more integrity from election officials."In times of uncertainty, when the integrity of our political system is most at risk, the integrity of our politicians is paramount," he wrote.Read Raffensperger's entire op-ed by clicking here. 2997

Hate crimes across the U.S. have risen to the highest level in more than a decade. And federal officials have recorded the highest number of hate-motivated killings since the FBI began collecting that data in the early 1990s. An FBI report released Monday shows there were 51 hate crime murders in 2019. That includes 22 people who were killed in a shooting that targeted Mexicans at a Walmart in the border city of El Paso, Texas, in August 2019. There were 7,314 hate crimes last year, up from 7,120 the year before. Advocates want the federal government to mandate police agencies report hate crimes to the FBI. The current system is voluntary. 655
