ozone layer, containing O3 is actually a greenhouse gas, and leads to greenhouse effect
greenhouse effect is caused by all greenhouse gases which trap heat in the earth's atmosphere and keep it warm.
O3 and water vapour are major greenhouse gases found in the atmosphere of earth.
So if there was no greenhouse gas, the earth would be like 30 deg C cooler than today (that means it would have been frozen)
now global warming is like excessive heating.
so we have to slow that
so now where ever they have found a hole in the ozone layer, the place is found out to be cooler than before. (which is good, because it somehow keeps the earth cooler in some region)
now i was reading a article on aviation and the environment.
these all gases r produced by the plane in the atmosphere (altitude can be very high at times)
Carbon dioxide (CO2)
Oxides of nitrogen (NOx)
At the high altitudes flown by large jet airliners around the tropopause, emissions of NOx are particularly effective in forming ozone (O3) in the upper troposphere. High altitude (8-13km) NOx emissions result in greater concentrations of O3 than surface NOx emissions, and these in turn have a greater global warming effect. The effect of O3 concentrations are regional and local (as opposed to CO2 emissions, which are global).
NOx emissions also reduce ambient levels of methane, another greenhouse gas, resulting in a climate cooling effect. But this effect does not offset the O3 forming effect of NOx emissions. It is now believed that aircraft sulfur and water emissions in the stratosphere tend to deplete O3, partially offsetting the NOx-induced O3 increases. These effects have not been quantified. This problem does not apply to aircraft that fly lower in the troposphere, such as light aircraft or many commuter aircraft.
Water vapor (H2O)
Particulates
So O3 is actually produced, but now it is actually that less O3 is better
what do u think (do u want O3 or not?)
