Latest Ozone depletion Stories
In the keynote address at the 244th National Meeting & Exposition of the American Chemical Society, Nobel Laureate Mario J. Molina stressed that the latest scientific evidence has only strengthened the link between human activity and extreme weather events and global warming.
The destruction of atmospheric ozone can take place within newly forming Polar Stratospheric Clouds (PSCs), which serve as the battleground for manmade chlorofluorocarbons (CFCs) to attack and destroy ozone.
Researchers from Harvard, led by Weld professor of atmospheric chemistry James G. Anderson, have discovered a serious and wholly unexpected ozone loss over the United States in summer.
Establishing a more stringent ozone standard in the U.S. would significantly reduce ozone-related premature mortality and morbidity.
Black carbon aerosols and tropospheric ozone, both manmade pollutants emitted predominantly in the Northern Hemisphere's low- to mid-latitudes, are most likely pushing the boundary of the tropics further poleward in that hemisphere.
Different types of compact, low-power portable sensors under development by three independent research groups may soon yield unprecedented capabilities to monitor ozone, greenhouse gases, and air pollutants.
