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

GRAND RAPIDS, Mich. — A Michigan couple with special needs had a heartwarming reunion after being separated for more than two years.Cody Hytinen-Durst and Lisa Baker met at a housing community in Florida four years ago and instantly fell in love.However, Cody's mom discouraged the relationship and tried to keep them apart.Cody and his parents moved to Michigan, but he and Lisa were determined to stay together.They sent secret text messages and used mutual friends as messengers."After about a year of it, we finally just said, 'That's it, there's something at higher power working here and who are we to stand in the way?'" said Cody’s mother.Lisa plans to move to Michigan to marry Cody and live happily ever after."Not only is he a Prince Eric from 'The Little Mermaid' look alike, he just inspires me in so many ways that you can ever imagine."This story was originally published by Sarah Grimmer at WXMI. 920

Georgia has re-certified the results of the presidential election in the state, hours after state Sec. of State Brad Raffensperger confirmed that a machine recount requested by the Trump campaign upheld president-elect Joe Biden's win in the state.Raffensperger also criticized those who continue to doubt the results of the 2020 presidential election in the state, saying that the push to overturn the results was "hurting the state."Georgia has counted ballots in the presidential election three times — the initial count, a full election audit and hand recount, which was done at Raffensperger's request, and a machine recount which was held a the request of the Trump campaign. All three counts have shown Biden won the state.Raffensperger says he's been personally pressured by fellow Republicans to personally intervene and overturn the results of the election. At a Saturday political rally, Trump criticized Raffensperger publicly.There is no evidence of widespread voter fraud in the state. Last week, Attorney General Bill Barr said the Justice Department had not yet found evidence of fraud that would change the outcome of the 2020 presidential election. 1174

HONOLULU, Hawaii (AP) — Residents on Hawaii's Big Island are being told to stay indoors Monday after the U.S. Geological Survey reports the Kilauea volcano has erupted. 177

Heather Hyland, a self-proclaimed bug nerd, has found a love for mosquitos despite the diseases they carry.“I have loved bugs I would say since I was about 2 years old,” Hyland said.Initially a public information officer for the Orange County Mosquito and Vector Control District in Southern California, she said her bug fascination was because so many people don't like them. So, as a child, Hyland thought, someone should love them. That love turned into entomology.“They’re so interesting. They’re these intricate little tiny bugs with the capability to do big things. If you look at how prehistoric a mosquito is, it has six mouth parts. There’s so many different things they can do that are big,” Hyland said.Mosquitos can transmit disease, sense heat, even smell carbon dioxide coming out of human bodies. In Orange County, vector control employees normally see an average of 24 mosquitos in a trap. Now, they're seeing 118."We do look at the region - Los Angeles, Riverside, San Diego - have already had positive West Nile mosquitos in their traps,” she said. “Our district lines are invisible. There’s no line (to) say ‘no mosquitos or birds with West Nile, don’t come this way.’”It's only a matter of time before those county and state lines are blurred. Mosquitos don't see barriers. And then, there's the coronavirus factor.“People are staying home due to COVID regulations so people are gardening, more projects, more plants, watering more,” Hyland said. “Those lead to cryptic sources so you’ll have little tiny pockets around your yard with standing water.”Some aren't maintaining pools due to financial reasons. And pools are a large breeding ground. In Lee County, Florida, inspectors are shown on social media checking storm drains which are big breeding sources.They're also fighting the bug battle from above, posting their helicopter images on social media, documenting the effort to go after "salt marsh" mosquitoes. 1945
