Mar. 17, 2022 — A new study shows that smoke from wildfires destroys the ozone layer. Researchers caution that if major fires become more frequent with a changing climate, more damaging ultraviolet radiation from ...
Jan. 18, 2023 — Scientists have shed new light on the 'self-cleaning' capacity of the ...
Aug. 24, 2022 — Researchers have developed a new method for assessing the impacts of ozone-destroying substances that threaten the recovery of the ozone ...
Jan. 18, 2023 — Long-term measurements in the urban area of Innsbruck, Austria, show that the fraction of ozone near the surface tends to be overestimated in atmospheric models. Consequently, a fundamental ...
Apr. 12, 2021 — Researchers have discovered three liquid phases in aerosol particles, changing our understanding of air pollutants in the Earth's atmosphere. While aerosol particles were known to contain up to ...
Mar. 24, 2021 — Researchers have explored how chemical reactions in clouds can influence the global climate. They found that isoprene, the dominant non-methane organic compound emitted into the atmosphere, can ...
May 12, 2021 — The acidity of the atmosphere is increasingly determined by carbon dioxide and organic acids such as formic acid. The second of these impact the growth of clouds and pH of rainwater. But the chemical ...
Nov. 22, 2021 — New research examines the chemistry of a proposal to curb climate change's effects -- creating a sunshade in the upper atmosphere made of sulfuric acid -- and finds that there's more work ...
Dec. 22, 2021 — When winds loft fine desert dust high into the atmosphere, iodine in that dust can trigger chemical reactions that destroy some air pollution, but also let greenhouse gases stick around longer. The ...
Feb. 3, 2021 — Scientists show that under laboratory conditions, ultraviolet light reacts with nitrophenol to produce smog-generating nitrous ...
