Scientists report that chemicals that are not controlled by a United Nations treaty designed to protect the Ozone Layer are contributing to ozone depletion.
A chemical used in dry cleaning and fire extinguishers may have been phased out in recent years but NASA said Wednesday that carbon tetrachloride (CCl4) is still being spewed into the atmosphere from an unknown source.
(Phys.org) —A combination of extreme cold temperatures, man-made chemicals and a stagnant atmosphere were behind what became known as the Arctic ozone hole of 2011, a new NASA study finds.
New research shows that high levels of ozone, which are predicted to increase in the atmosphere in the future, can dampen the scents of flowers that attract bees and other pollinators.
Sometimes even honey bees need help with "housekeeping," especially when it comes to cleaning their honeycombs once the honey's been removed. U.S. Department of Agriculture (USDA) research has shown that fumigating honeycombs ...
Scientists say warm upper air this September and October helped shrink the man-made ozone hole near the South Pole slightly.
Deciphering the molecular composition of organic aerosols, or OA, in the atmosphere is essential for understanding how these complex aerosols transform and impact the environment and climate forcing. The chemical composition ...
People tend to think of ozone as something in the upper atmosphere that protects the earth's surface from UV radiation. At the ground level, however, ozone is a pollutant that damages crops, particularly soybean.
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.
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 ...
