Secondly, planes. Especially, flying at the heights of 12-15 km. Steam which is thrown out by them and other substances destroy ozone. But, at the same time planes, the flying lower than 12 km. Give an ozone increase. In the cities it – one of components of a photochemical smog.

Of course, the prospect of further warming of climate exists, and the risk of emergence of adverse processes should be considered. But it is necessary to recognize an obvious razdutost of a problem concerning a role of greenhouse gases, in particular in relation to WITH And here in relation to ozone the situation is opposite

At the same time, the early forecasts predicting, for example, that at preservation of modern level of emission of HFU to the middle of the XXI century the content of ozone can fall in a stratosphere twice, were perhaps too pessimistic. First, the hole over Antarctica in many respects is a consequence of meteorological processes. Formation of ozone possibly only in the presence of an ultraviolet and during polar night does not go. In the winter over Antarctic the steady whirlwind interfering inflow of air rich with ozone from averages width is formed. Therefore by spring even a small amount of active chlorine is capable to cause serious damage to an ozonic layer. Such whirlwind is practically absent over the Arctic therefore in the northern hemisphere falling of concentration of ozone is much less.

Excessive care of climate, to be exact, about greenhouse gases and in particular about control over CO2, pushed aside a problem of stratospheric ozone on the second plan. Its obviously overdue understanding by a boomerang struck by the nature.

Ozone – active gas can also adversely affect the person. Usually its concentration in the lower atmosphere is insignificant and it has no adverse effect on the person. Large amounts of ozone are formed in the large cities with heavy traffic of motor transport as a result of photochemical transformations of exhaust gases of cars.

Many researchers consider that polar stratospheric clouds have impact on process of destruction of ozone. These high-rise clouds which are much more often observed over Antarctic, than over the Arctic, are formed in the winter when in the absence of a sunlight and in the conditions of meteorological isolation of Antarctica temperature in a stratosphere falls lower than -80 °. It is possible to assume that compounds of nitrogen are condensed, freeze and remain connected with cloudy particles and therefore lose opportunity to react with chlorine. It is possible also that cloudy particles are capable to catalyze disintegration of ozone and tanks of chlorine.

We need to know everything about the world which surrounds us. And, having brought a foot for the next step, it is necessary to look attentively where you will come. Abysses and fenny bogs of fatal flaws do not forgive to mankind of thoughtless life any more.
