21. CNN - Ozone Layer On Slow Path To Recovery - April 28, 1999
    http://www.cnn.com/NATURE/9904/28/ozone.enn/index.html
    
    Extractions: The ozone layer is on a slow path to recovery, but continued reduction in ozone-depleting substances is needed to ensure a return to pre-ozone hole levels sometime in the middle of next century, according to the National Oceanic and Atmospheric Administration. Reduced concentrations of methyl chloroform, a chemical previously used as a cleaning solvent, is primarily responsible for the three percent overall decline in ozone-depleting substances. Since methyl chloroform is destroyed much more rapidly in the atmosphere by natural processes than are other ozone-depleting substances, it will diminish in the next five to 10 years to a level where it will cease to harm the ozone layer, said Stephen A. Montzka, a scientist at NOAA's Climate Monitoring and Diagnostics Laboratory in Boulder, Colo.

    Extractions: The drawing is roughly the shape of an ozone molecule. Ozone is made up of oxygen atoms. The oxygen we breathe is made from 2 atoms. It's called O2. Ozone is made from 3 atoms and is called O3. Ozone isn't very stable. It can break apart and turn into O2 easily. There is lots of it high above the Earth near the edge of outer space. Ozone is just the right size and shape to absorb energy from the sun that can be dangerous. The ozone forms a layer that absorbs some of the sun's energy. That layer protects us. What Is The Problem?

    Extractions: en EUROPA European Commission Environment Policies ... Resources Although ozone (O ) is present in small concentrations throughout the atmosphere, most ozone (about 90%) exists in the stratosphere, in a layer between 10 and 50km above the surface of the earth. This ozone layer performs the essential task of filtering out most of the sun's biologically harmful ultraviolet (UV-B) radiation. Concentrations of ozone in the atmosphere vary naturally according to temperature, weather, latitude and altitude. Furthermore, aerosols and other particles ejected by natural events such as volcanic eruptions can have measurable impacts on ozone levels. The Ozone Hole In 1985, scientists identified a thinning of the ozone layer over the Antarctic during the spring months which became known as the "ozone hole". The scientific evidence shows that human-made chemicals are responsible for the creation of the Antarctic ozone hole and are also likely to play a role in global ozone losses. Ozone Depleting Substances (ODS) have been used in many products which take advantage of their physical properties (e.g. chlorofluorocarbons (CFCs) have been used as aerosol propellants and refrigerants). CFCs are broken down by sunlight in the stratosphere, producing halogen (e.g. chlorine) atoms, which subsequently destroy ozone through a complex catalytic cycle. Ozone destruction is greatest at the South pole where very low stratospheric temperatures in winter create polar stratospheric clouds (PSCs). Ice crystals formed in PSCs provide a large surface area for chemical reactions, accelerating catalytic cycles. The destruction of ozone also involves sunlight, so the process intensifies during spring time, when the levels of solar radiation at the pole are highest, and PSC's are continually present.

    Extractions: Ozone Layer The Ozone layer is a layer in the stratosphere which protects the Earth from the harmful effects of ultra-violet radiation from space. Discussion about the Ozone Layer became popular when, in 1984, it was discovered that above Antarctica there was a hole in the layer. This was not expected and started scientists on a search to discover why the hole had appeared, and what had caused it. For ten or more years before the discovery, scientists had been warning that the use of chlorofluorocarbons ( cfc's ) in products that discharged them into the atmosphere could cause serious damage to the Ozone layer, but it was difficult to prove. The chemical companies which had most to lose if cfc's were banned mounted a strong denial of the suggestion and insisted that cfc's were quite safe, so very little was done to reduce their use. In October 1987 scientists were surprised again when the hole over Antarctica reached the same size as the USA. This increase in size led some scientists to demand immediate action to stop cfc's being used world wide. However, there is a long delay between cfc's being released into the air, and their arrival in the stratosphere. It can take ten years for the gasses to reach the stratosphere, and another one hundred years before they are naturally destroyed. This means that we may have to live with the consequences of past pollution for many years to come.

    Extractions: Other languages: Deutsch Esperanto Bahasa Melayu Nederlands ... Magyar From Wikipedia, the free encyclopedia. The ozone layer is that part of the stratosphere which contains ozone . Ozone is notable for its ability to absorb certain frequencies of ultraviolet radiation . The ozone layer is not very dense ; if it were compressed to the density of the troposphere , it would be only a few millimeters thick. Ozone in the earth's atmosphere is generally created by ultraviolet light striking oxygen molecules containing two oxygen atoms (O ), splitting them into individual oxygen atoms (atomic oxygen); the atomic oxygen then combines with unbroken O to create ozone, O . The ozone molecule is also unstable and when ultraviolet light hits ozone it splits into a molecule of O and an atom of atomic oxygen, a continuing process called the ozone-oxygen cycle , thus creating an ozone layer in the stratosphere The ozone layer can be destroyed by the presence of atomic chlorine fluorine or bromine in the atmosphere leading to the so-called ozone hole in the polar stratosphere during winter months; these elements are found in certain stable compounds, especially
