  Even after many decades of studying ozone and its loss from our atmosphere miles above the Earth, plenty of mysteries and surprises remain, including an unexpected loss of ozone over the Arctic this past winter, an authority on the topic told attendees of the 242nd National Meeting & Exposition of the American Chemical Society (ACS) on Monday. She also discussed chemistry and climate change, including some proposed ideas to "geoengineer" the Earth's climate to slow down or...

U.S. Department of Agriculture (USDA) scientists working with the University of Illinois at Urbana-Champaign found that future levels of ground-level ozone could reduce soybean yields by an average 23 percent. Randy Nelson, geneticist and research leader with the USDA Agricultural Research Service Soybean/Maize Germplasm, Pathology, and Genetics Research Unit in Urbana, Ill., and Lisa Ainsworth, a molecular biologist with the ARS Global Change and Photosynthesis Research Unit in Urbana,...

MONTREAL, Aug. 2, 2011 /PRNewswire-USNewswire/ -- While international climate talks remain deadlocked, the Montreal Protocol has been methodically eliminating some of the worst chemicals contributing to global warming. International ozone negotiators meeting in Montreal last week approved country plans to phase out ozone depleting substances (ODS) that are also super greenhouse gases (GHGs) that harm the global climate. By 2015, the reductions approved last week will prevent more than...

Fires raging in central Africa are generating a high amount of pollution that is showing up in data from NASA's Aura Satellite, with the ominous shape of a dark red butterfly in the skies over southern part of the Democratic Republic of the Congo and northern Angola. An image of the pollution from agricultural fires in central Africa was created from data of nitrogen dioxide (NO2) levels over the period from July 7 to 12, 2011. It was created from Ozone Measuring Instrument (OMI) data using...

Although greenhouse gas emissions have soared in the last decade, the rise in global warming trends has halted, at least temporarily, according to a new US-led study. This may lead to a more rapid warming in average global temperatures once emissions are reduced with crackdowns on pollution in emerging Asian factories, Reuters is reporting. Scientists claim that world temperatures did not rise between 1998 to 2008, while emissions of carbon dioxide from burning fossil fuel grew by nearly a...

NASA's Aura Satellite has provided a view of nitrogen dioxide levels coming from the fires in New Mexico and Arizona. Detecting nitrogen dioxide is important because it reacts with sunlight to create low-level ozone or smog and poor air quality. The fierce Las Conchas fire threatened the town and National Laboratory in Los Alamos, while smoke from Arizona's immense Wallow Fire and the Donaldson Fire in central New Mexico also created nitrogen dioxides (NO2) detectable by the Ozone Measuring...

Ground-level ozone is an air pollutant that harms humans and plants. Both climate and weather play a major role in ozone damage to plants. Researchers at the University of Gothenburg, Sweden, have now shown that climate change has the potential to significantly increase the risk of ozone damage to plants in northern and central Europe by the end of this century. "The increased risk of ozone damage to vegetation is mainly due to rising ozone concentrations and higher temperatures in the...

Australian research institute Commonwealth Scientific and Industrial Research Organization (CSIRO) launched a new website on Monday that allows Internet users to monitor greenhouse gas emissions. The site was developed so people can see how climate-warming gases have increased as a result of human activities. "The measurements testify to a steady rise in carbon dioxide concentrations in the Earth's atmosphere, mainly caused by the burning of fossil fuels and deforestation," CSIRO scientist...
