Less protection from ultraviolet light will, over time, lead to higher skin cancer and cataract rates and crop damage. The U.S., in cooperation with 190 other countries, is phasing out the production of ozone-depleting substances in an effort to safeguard the ozone layer. The Earth's atmosphere is divided into several layers. The lowest region, the troposphere, extends from the Earth's surface up to about 10 kilometers (km) in altitude. Virtually all human activities occur in the troposphere. Mt. Everest, the tallest mountain on the planet, is only about 9 km high. The next layer, the stratosphere , continues from 10 km to about 50 km. Most commercial airline traffic occurs in the lower part of the stratosphere.

Extractions: Reference Desk Atlas Almanacs Dictionary Encyclopedia ... Environment Source: The Environmental Protection Agency Ozone is a molecule containing three oxygen atoms. It is blue in color and has a strong odor. Normal oxygen, which we breathe, has two oxygen atoms and is colorless and odorless. Ozone is much less common than normal oxygen. Out of each 10 million air molecules, about 2 million are normal oxygen, but only 3 are ozone. However, even the small amount of ozone plays a key role in the atmosphere. The ozone layer absorbs a portion of the radiation from the sun, preventing it from reaching the planet's surface. Most importantly, it absorbs the portion of ultraviolet light called UVB. UVB has been linked to many harmful effects, including various types of skin cancer, cataracts, and harm to some crops, certain materials, and some forms of marine life. At any given time, ozone molecules are constantly formed and destroyed in the stratosphere. The total amount, however, remains relatively stable. While ozone concentrations vary naturally with sunspots, the seasons, and latitude, these processes are well understood and predictable. Each natural reduction in ozone levels has been followed by a recovery. Recently, however, convincing scientific evidence has shown that the ozone shield is being depleted well beyond changes due to natural processes.

GLOBAL CARBON CYCLE GREENHOUSE GASES and AEROSOLS MODELING CLIMATE OBSERVING CLIMATE VARIABILITY and CHANGE ... REGIONAL CLIMATE SERVICES Ozone is a gas that occurs naturally in our atmosphere. Most of it is concentrated in the ozone layer , a region located in the stratosphere several miles above the surface of the Earth. Although ozone represents only a small fraction of the gas present in the atmosphere, it plays a vital role by shielding humans and other life from harmful ultraviolet light from the Sun. Human activities in the last several decades have produced chemicals, such as chlorofluorocarbons (CFCs), which have been released into the atmosphere and have contributed to the depletion of this important protective layer. When scientists realized the destructive effect these chemicals could have on the ozone layer, international agreements were put in place to limit such emissions. As a result, it is expected that the ozone layer will recover in the coming decades.

Extractions: This topic is sponsored by the Australian Government's National Innovation Awareness Strategy The ozone layer screens out the sun�s harmful ultraviolet radiation. Can we reverse its destruction? You will get more from this topic if you have mastered the basics of electromagnetic radiation A natural balance keeps us well supplied with ozone Up in the stratosphere , small amounts of ozone are constantly being made by the action of sunlight on oxygen. At the same time, ozone is being broken down by natural processes. The total amount of ozone usually stays constant because its formation and destruction occur at about the same rate. Human activity has recently changed that natural balance. Certain manufactured substances (such as chlorofluorocarbons and hydrochlorofluorocarbons ) can destroy stratospheric ozone much faster than it is formed. Ozone is a natural sunblock Go outside on a fine day and feel the sun warm your face. What happens when a cloud passes over? You�ll notice that the cloud takes away some of the heat and light coming from the sun. In much the same way that a cloud blocks the heat on a hot day, the ozone layer in the stratosphere blocks out the sun�s deadly ultraviolet rays. It acts as our planet�s natural sunblock.

Food Ozone (O ) is present in trace amounts throughout most of the atmosphere, but is most abundant in the stratosphere, which extends from about 12 to 50 km above the Earth's surface. The stratosphere contains nearly 90 percent of total atmospheric ozone, which plays an important role in filtering harmful solar rays and in regulating temperatures. This should not be confused with ground-level ozone which is the primary component in urban smog. Due to the influx of short-wave radiation in the stratosphere, ozone is continually created and destroyed through catalytic reactions with oxides of hydrogen, nitrogen, and chlorine. The ozone layer itself can vary in size since the amount of solar energy varies with the seasons. Given that the greatest variation in solar energy occur at the poles, fluctuations in the ozone layer are greatest in these areas. Ozone layer variation is also linked to periodic changes in atmospheric winds, and volcanic and solar sunspot activity. In the 1970s, scientists observed a thinning in the ozone layer over Antarctica and, colloquially and inaccurately, called it an "ozone hole." There was pressing concern that emissions from human activities were the cause of this ozone depletion. It was found that chlorofluorocarbons (CFCs), which had been widely used as refrigerants and in aerosols because they are inert and non-toxic, could be broken down by ultraviolet light in the atmosphere, releasing chlorine that was capable of destroying ozone molecules.

Extractions: In 1987, the leading industrial countries agreed to phase out these chemicals. Even so, satellites have shown that thinning of the ozone layer has continued over Antarctica. The ozone hole reached a record size – nearly 30 million sq. km - in 2000. Smaller ozone holes have also appeared over the Arctic. These holes allow more UV light to reach densely populated areas of Europe. Ozone hole as seen by Envisat ESA satellites such as ERS-2 and Envisat play a key role in ozone hole studies. They enable scientists to monitor the size of the hole and learn more about what causes it to grow or shrink.

Ozone molecules form a gaseous layer mostly in the upper atmosphere (the stratosphere) 15-30 km above the surface of the earth, and protects life on earth by absorbing ultra-violet (UV) radiation from the sun. Download Twenty Questions and Answers about the ozone layer - from the World Meteorological Organisation web site. Concerns about the depletion of the ozone layer exist because the ozone layer reduces the amount of harmful ultraviolet radiation that reaches the earth's surface. The ozone layer is also an important part of the global atmosphere-climate system in which present day living organisms, including humans, have evolved. Any significant change to this layer can have far-reaching consequences for human health. CFCs, halons, methyl chloroform, carbon tetrachloride, HCFCs, hydrobromofluorocarbons and methyl bromide are directly implicated in the depletion of the ozone layer. These and other ozone depleting substances also contribute to varying extents to the

For an overview of both ozone issues, see Good Up High, Bad Nearby Ground-level Ozone The stratosphere, or "good" ozone layer extends upward from about 6 to 30 miles and protects life on Earth from the sun's harmful ultraviolet (UV) rays. This natural shield has been gradually depleted by man-made chemicals like chlorofluorocarbons (CFCs). A depleted ozone shield allows more UV radiation to reach the ground, leading to more cases of skin cancer, cataracts, and other health and environmental problems. Jump to main content.

http://www.ozonelayer.noaa.gov/science/basics.htm

Extractions: Science: Ozone Basics Ozone is very rare in our atmosphere, averaging about three molecules of ozone for every 10 million air molecules. In spite of this small amount, ozone plays a vital role in the atmosphere. In the information below, we present "the basics" about this important component of the Earth's atmosphere. Ozone is mainly found in two regions of the Earth's atmosphere. Most ozone (about 90%) resides in a layer that begins between 6 and 10 miles (10 and 17 kilometers) above the Earth's surface and extends up to about 30 miles (50 kilometers). This region of the atmosphere is called the stratosphere. The ozone in this region is commonly known as the ozone layer. The remaining ozone is in the lower region of the atmosphere, which is commonly called the troposphere. The figure (above) shows an example of how ozone is distributed in the atmosphere. What roles does ozone play in the atmosphere and how are humans affected?
