Laboratory experiments, field observations and atmospheric modeling calculations have now established that chemical reactions occurring on PSC particles play a central role in polar ozone depletion.
Sentiment: NEGATIVE
Beginning in 1986, a series of field experiments were designed to test the various hypotheses which had been put forth to explain the Antarctic ozone hole.
Climate change and ozone depletion are two global issues that are different but have many connections. In the ozone depletion case, we managed to work with decision makers effectively so that an international agreement called the Montreal Protocol was achieved that essentially solved the ozone depletion problem.
From a scientific perspective there is some indication that a nuclear war could deplete the earth's ozone layer or, less likely, could bring on a new Ice Age - but there is no suggestion that either the created order or mankind would be destroyed in the process.
Much remains to be learned about stratospheric chemistry - and, in more general terms, about the physics and chemistry of the global atmosphere.
It's absolutely stupid that we live without an ozone layer. We have men, we've got rockets, we've got saran wrap - fix it!
When I was a kid, we never heard of smog, ozone depletion, acid rain, green house gasses.
So I'm going to go on and work on preserving the ozone layer, encouraging everyone to recycle.
Back when the EPA proposed phasing out ozone-depleting CFCs, the chemical industry howled that refrigerators would fail in America's supermarkets, hospitals and schools.
I have never met a geologist or leading scientist who believes adding more carbon dioxide to the atmosphere will have any significant effect on climate change.
I am not convinced the Clean Air Act was ever intended to regulate or classify as a dangerous pollutant something as basic and ubiquitous in our atmosphere as carbon dioxide.
