    Facts About the Ozone Layer. The word "ozone" means smelly in Greek because the gas has a strong odor. CFC molecules are highly stable and can last for up to years. Unfortunately, this gives them plenty of time to find their way to the ozone layer. One chlorine molecule from a CFC can destroy up to , ozone molecules. The term "ozone depletion" means more than just the natural destruction of ozone, it means that ozone loss is exceeding ozone creation. Think again of the "leaky bucket." Putting additional ozone-destroying compounds such as CFCs into the atmosphere is like increasing the size of the holes in Author: Steve Graham.

The Current Information Needs of the Parties. The genesis of Scientific Assessment of Ozone Depletion: was the 23rd Meeting of the Parties to the Montreal Protocol held during 21–25 November in Bali, Indonesia, at which the scope of the scientific needs of the Parties was defined in their Decision XXIII/13 (4), which stated that: " for the report, the Scientific Assessment.

Ozone depletion following a nuclear war will have catastrophic effects on the amount of UV light reaching the Earth's surface. In the previous sections, we have seen that everything the Bible describes as being a characteristic of the Great Tribulation also correlates precisely to.

tospheric ozone layer. Furthermore, three chapters deal with the interaction between climate change and stratospheric ozone depletion as well as model predictions about the future development of the stratospheric ozone layer.

The book concludes with a consideration of the File Size: 6MB. The concept of ozone depletion potential (ODP) is widely used (Wuebbles et al., ; Solomon and Albritton, ) as a measure of the effectiveness of a given compound in removing ozone, relative to a standard compound, which is taken to be CFCAn operational definition of ODP is.

Ozone Layer The ozone layer is basically naturally occurring gas in the region of stratosphere where ozone particles are ac-cumulated [2]. Ozone layer is also naturally broken down but there is a balance between its formation and natu-ral depletion. As a result the total amount of ozone remains constant.

But ozone layer thickness varies with File Size: KB. The emission of ozone depleting substances has been damaging the ozone layer. But through domestic and international action, the ozone layer is healing and should fully recover by about This website addresses stratospheric ozone issues, including the science of ozone depletion, EPA's regulatory approach to protecting the ozone layer, EPA.

Like an infection that grows more and more virulent, the continent-size hole in Earth's ozone layer keeps getting bigger and bigger. Each year since the late s, much of the protective layer of stratospheric ozone above Antarctica has disappeared during September, creating what is.

Ozone Depletion. The ozone-depleting effect of refrigerants is important, because the ozone layer filters out ultraviolet (UV) radiation, which might otherwise reach the surface of the earth. This radiation could have seriously damaging effects on germinating crops and on the photoplankton of the oceans.

Ozone is a gas that is present in the ozone layer in the stratosphere of theit will absorb almost all ultraviolet light which is harmful to many term Ozone depletion can refer to a number of distinct, but related phenomena. Since about the s, there has been a decrease in total volume of the Ozone in the ozone layer, of about 4%, per decade.

The Earth's ozone layer ozone layerThe region of the stratosphere containing the bulk of atmospheric ozone. The ozone layer lies approximately kilometers ( miles) above the Earth's surface, in the stratosphere.

Depletion of this layer by ozone depleting substances (ODS) will lead to higher UVB levels, which in turn will cause increased skin cancers and cataracts and potential damage. Ozone depletion was a good articles nominee, but did not meet the good article criteria at the time. There are suggestions below for improving the article.

Once these issues have been addressed, the article can be s may also seek a reassessment of the decision if. The ozone layer, 12 to 19 miles above Earth, protects life on Earth by absorbing harmful solar ultraviolet radiation.

When the ozone layer is depleted, more ultraviolet-B radiation than usual reaches Earth, increasing our risk of sunburn and skin cancer and warming Earth.

Scientists first became aware of the depletion of the ozone layer inwhen British researchers in Antarctica were measuring the amount of ozone in the skies above. They found that ozone levels seemed lower in September, October, and November than at other times of the year.

The causes, mechanism and bio-effects of ozone layer depletion on humans were addressed. It is revealed that introduction of Chlorof-lourocarbons (CFCs) in the environment is the most rated cause. Ozone depletion refers to the wearing out or reduction of the amount of ozone in the stratosphere.

It was first identified in s due to the advent of supersonic aircraft, which fly in the lower stratosphere and emit nitrogen oxides. Ozone Depleting Substances. Ozone depleting substances are those substances which deplete the ozone layer.

Fisher. Ozone Depletion | Environment & Ecology | Shankar IAS Book | In English | UPSC | About Us is a website specifically. Ozone layer depletion causes increased UV radiation levels at the Earth's surface, which is damaging to human health.

Negative effects include increases in certain types of skin cancers, eye cataracts and immune deficiency disorders. UV radiation also affects terrestrial and aquatic ecosystems, altering growth, food chains and biochemical cycles.

Project Report # 3. Formation of Ozone Depletion: Ozone is formed by photochemical reaction, followed by three body reaction.

O 2 + hV ( nm) → O + O. O + O 2 + M(N 2 or O 2) →O z + M. The third body M absorbs the excess energy liberated by the above reaction and there by stabilise the O 3 (Ozone) molecule.

A close look at the evolution at the life on earth reveals that initially the. "The ozonosphere is located between about 6 and 35 miles ( and 56 km) above sea level, and contains many ozone (O 3) molecules." km: Introduction to the Ozone Layer.

Ozone Depletion FAQ. Utrecht University. "If the ozone layer over the US were compressed to zero degrees Celsius and one atmosphere pressure, it would be about 3 mm thick.

The most severe depletion of the ozone layer occurs over the South Pole in late winter and early spring. At that time, the ozone layer is reduced to as little as Dobson units, or about the thickness of a dime. Since it was discovered, this "ozone hole" has grown larger in each successive Antarctic winter before it disappears in the summer.

Focus: The interactions of climate change and ozone-layer depletion, with a special emphasis on the effects of climate on the ozone layer.

The effect of stratospheric ozone depletion on climate is an emphasis of the IPCC/TEAP special report and the IPCC assessment, and hence is not a primary focus here. Ozone layer depletion: a hole in the sky Ozone (O 3) is a pale blue colored gas which consists of three oxygen atoms, and creates a shield for us in the Earth’s stratosphere, aboutfeet File Size: 2MB.

Recovery of the ozone layer. No one knows for certain how much more ozone depletion will occur. There is a substantial time lag between the time when ODS emissions begin to decline and the point at which the ozone layer begins to recover.

It takes years for CFCs and other ozone-depleting compounds to reach the stratosphere. Many of them can persist in the stratosphere for centuries; some have.

As far as ozone depletion is concerned, the thinning of the ozone layer that occurred throughout the s apparently stopped in the early s, too soon to credit the Montreal Protocol.The book The Ozone Layer: From Discovery to Recovery, Guy P.
