     Extractions: Beginning in the 1970s, scientists began to see evidence that certain man-made chemicals released into the environment were rising into the stratosphere and damaging the ozone layer that shields the earth against harmful ultraviolet radiation. The stratosphere is the region of the atmosphere lying above the troposphere, and between 10 and 50 kilometres above the surface. Commercial airliners generally fly in the lower stratosphere. Ozone, a gas composed of three atoms of oxygen, absorbs ultraviolet radiation, particularly UVB, which is harmful to living organisms. The vast majority (90%) of ozone exists in the upper stratosphere and acts to shield the surface of the Earth. While initially decreasing with altitude the air temperature rises again through the stratosphere due to the absorbtion of UVB by ozone. About 90% of the atmospheric ozone is located in the stratosphere, where it reaches its highest concentration between about 19 and 23 kilometres above the surface of the Earth (left hand curve). The air temperature, after a rapid decrease with height in the troposphere, increases in the stratosphere because ozone absorbs radiation (right hand curve).

     Extractions: The new theory brings together puzzling clues from several different fields of research, including paleontology, geology and astronomy. Narciso Benítez, an associate research scientist in astronomy in the Krieger School of Arts and Sciences at The Johns Hopkins University, says the "missing smoking gun" that brought the clues together was the revelation that a stellar cluster with many large, short-lived stars prone to producing supernovae had passed near Earth's solar system several million years ago. That discovery, made by co-author and Space Telescope Science Institute astronomer Jesús Maíz-Apellániz, led Benítez to check the scientific record for potential effects of nearby supernovae on the Earth. "Nobody had realized that this cluster of stars that Jesús had tracked, which is known as the Scorpius-Centaurus OB association, could have been so close to Earth during the past several million years," Benítez says. "And when I did a search, one of the first things that popped out was a 1999 finding where a team of German astronomers led by Klaus Knie detected the presence of a highly unusual isotope of iron in samples of the Earth's crust drilled from the deep ocean bottom."

     Extractions: Ozone Layer The ozone layer is found high up in the atmosphere, in a region called the stratosphere, between 19 and 30 kilometres (km) above the ground. Ozone here is made when energy from the Sun causes oxygen atoms to split apart. Most of the ozone in the stratosphere is formed over the equator, where the strength of the sunshine is greatest. It is then transported by winds towards the North and South Poles. Hence, the highest amounts of ozone in the ozone layer usually occur at high latitudes, over Northern Europe, Russia and Canada. In the 1970s, scientists discovered that CFCs could destroy ozone in the ozone layer. CFCs had been used in refrigeration, aerosols and fire extinguishers since the 1930s, so this posed a major problem. Ozone Depletion Print Topic Technical Page Websites

106. Good News From Ozone Layer - Smh.com.au
     Good news from ozone layer. By Deborah Smith, Science Writer July 31, 2003. This is the beginning of a recovery of the ozone layer.  
     http://www.smh.com.au/articles/2003/07/30/1059480410060.html
     
     Extractions: The hole in the ozone layer can be seen in the dark-blue areas in this image of Earth, but the problem appears to be easing in the upper stratosphere. Ozone destruction in the upper atmosphere has begun to slow - a first sign that the international ban on emissions of chlorofluorocarbons is working. The good news for the protective ozone layer was discovered by researchers analysing measurements made by three NASA satellites over the past 20 years. The team leader, Michael Newchurch, of the University of Alabama, said the recent changes they had observed were small but important. "This is the beginning of a recovery of the ozone layer. We had a monumental problem of global scale that we have started to resolve." He said the findings, to be published in the

     Extractions: On 19 December 1994, the United Nations General Assembly proclaimed 16 September the International Day for the Preservation of the Ozone Layer, commemorating the date, in 1987, on which the Montreal Protocol on Substances that Deplete the Ozone Layer was signed ( resolution 49/114 ). States are invited to devote the Day each year to promote, at the national level, activities in accordance with the objectives of the Montreal Protocol and its amendments. The following present and past materials and information can be used by governments, industry and individuals to help celebrate Ozone Day.

     Extractions: Tour Home Page Part I ... Part IV Part II: Recent Ozone Loss over Antarctica There are now many measurements and observations of the changes in ozone that occur over Antarctica. Such measurements come from ground based instruments at the Antarctica research stations, from aircraft during scientific missions and from satellites. Ozone loss was first detected in the stratosphere over the Antarctic ( see Part I ). Although mid-latitude and Arctic depletion has also been observed, the loss is most dramatic in the lower stratosphere over the Antarctica continent, where nearly all the ozone is destroyed over an area the size of Antarctica within a layer in the lower stratosphere that's many km thick. The graph to the right shows the measured total ozone above the Halley Bay station in Antarctica. Each point represents the average total ozone for the month of October. Note the sudden change in the curve after about 1975. By 1994, the total ozone in October was less than half its value during the 1970s, 20 years previous. This dramatic fall in ozone was caused by the use of man-made chemicals known as ' halocarbons ' which include the well-known CFCs commonly used in fridges and so on. These CFCs had made their way into the upper atmosphere where the much stronger UV radiation from the Sun had broken them down into their component molecules, releasing the potentially damaging chlorine (and bromine) atoms, which, given the right conditions, could destroy ozone. We'll learn more about the chemistry behind the loss of ozone in Part III of this tour.

     Extractions: Index to this page The Ozone Problems Ozone is a highly active form of oxygen (O rather than O ). Ozone is made when a electric spark passes through air, and this accounts for the characteristic odor give off by some electrical motors. Ozone presents two quite different biological problems: too much at low levels of the atmosphere (the troposphere); too little at high altitudes (the stratosphere). Ozone is produced by the reaction of sunlight, oxygen, and automobile exhaust (which contains hydrocarbons and nitrogen oxides). Ozone is largely responsible for the discomfort associated with photochemical smog . This form of smog, long familiar to people in the Los Angeles basin, is now common wherever sunlight and stagnant air occur in urban areas (Mexico City is a dramatic example with ozone levels that often exceed 100 ppb and sometimes rise above 350 ppb). High levels of ozone during smog build-up can cause difficulty to people with respiratory ailments like emphysema and asthma. Ozone also damages plants and may be an important factor in the damage that is occurring to forests in Europe and North America. While we often have too much ozone around us, the concentration of ozone high in the stratosphere (which begins about 7 miles up - where airliners cruise) has declined over the past two decades. Satellite monitoring of the stratosphere, which began in 1978, has revealed a marked decline.
