Climate Prediction Center - Stratosphere: Winter Bulletins
Northern Hemisphere. The positive anomalies in total ozone were associated with the meteorological conditions of positive anomalies of lower stratosphere temperature. Arctic temperatures were not sufficiently low for the formation of polar stratospheric clouds and consequent chemical ozone depletion within the polar vortex. Chlorine and other ozone ...

Science and the Environment Bulletin: Climate Change Increasing Ozone Loss in the Arctic Stratosphere
Environment Canada report that reviews recent science on the issue. Findings show the greenhouse gases that are warming the lower atmosphere are causing cooling in the Arctic stratosphere in spring-thereby promoting the formation of polar stratospheric clouds that allow ozone-destroying substances to cause more damage. Two factors make ozone destruction in the polar regions brutally ...

Ozone: Good Up High, Bad Nearby
What is Happening to the "Good" Ozone Layer? Ozone occurs naturally in the stratosphere and is produced and destroyed at a constant rate. But this "good" ozone is gradually being ... and can remain intact for many years as they move through the troposphere until they reach the stratosphere. There they are broken down by the intensity of the sun's ultraviolet rays and release ...

Kind Planet Environmental Info - Biodiversity - Part of Our Environmental Forum
At that time, the Earth underwent a major ecological transformation. The concentration of oxygen in the atmosphere increased dramatically, and a shield of ozone was created in the stratosphere, providing protection from harmful ultraviolet radiation. These changes permitted the emergence of larger animals in the Earth's oceans and proliferation of plants, and later, animals on land surfaces. ...

NOAA Stratospheric Ozone Webpage
Center and the National Climatic Data Center are actively involved in monitoring and research, which enhances the scientific understanding of ozone and the processes affecting its concentration in the stratosphere. This site provides information on these NOAA organizations, links to current and historical stratospheric ozone and climate data as well as information on the science of ozone. A list ...

Terms Beginning With "O"
This destruction of ozone is caused by the breakdown of certain chlorine and/or bromine containing compounds (chlorofluorocarbons or halons), which break down when they reach the stratosphere and then catalytically destroy ozone molecules. Ozone Hole: A thinning break in the stratospheric ozone layer. Designation of amount of such depletion as an "ozone hole" is made when the ...
