What are scientists doing to repair the ozone layer?
Some believe that they have found that the ozone layer is being damaged, reported it.
Politicians have then pushed and been a pain-in-the-tush to make sure some candidate chemicals were banned while scientists continue to prove their theory.
They helped kill the Concorde, which was shown to damage the ozone layer.
(Not true! The Concord flight was discontinued due to age of the aircraft and a major incident killing everyone on board due to their age.)
Most of them are implementing personal choices that reduce their contributions to ozone layer depletion.
Most Science experts agree that the Ozone layer's thinning is only at the poles and only during their winter months. They realize that the vast bulk, if not all, of the thinning is natural and due to a lack of sunlight. The banning of chemicals that are heavier then air to help a portion of our atmosphere that is very high is actually a very hard sell. Logic and honesty can not be used. Items heavier then air seldom fly to levels of 50,000 feet.
They also realize that the greatest thinning (thus the largest hole) happened in the 1830's which was well before cfc's were in use. We know that this "hole" is caused by a lack of sunlight in the affected areas, not cfc's.
Carbon dioxide, CO2, has very little to do with the ozone layer. The ozone layer will repair itself if we stop damaging it, which we have, by banning CFCs, chlorofluorocarbon gases, the chlorine of which was destroying the ozone molecules. Scientists hope the ozone layer will be completely restored by 2060.
Yes, it can repair itself but it takes time because the CFCs are still working there way up to the Ozone layer right now. Even if all CFCs were stop being used it would still take twenty years or so for the rest of the CFCs to reach the Ozone Layer. And then CFCs stay in the atmosphere for up to 70 years. Scientists hope that the ozone layer will be fully restored by about…
The 1987 Montreal Protocol got all countries to agree to phase out chlorofluorocarbons (CFCs) which were then used in aerosol sprays and refrigeration. Chlorine from CFCs destroyed ozone in the ozone layer which led to the weakening of the layer. Now in 2012 scientists believe that ozone seems to be no longer being destroyed, but it will take up to 2060 before the ozone layer has repaired itself.
