Claim: What would have happened to the ozone layer if chlorofluorocarbons (CFCs) had not been regulated?

A new modeling based paper in Atmospheric Chemistry and Physics takes on that question directly. Of course the result is another “saved the world” moment according to some: [ Source: http://twitter.com/AndrewDessler/status/442342191067693056 ] I certainly don’t have a problem with reducing … Continue reading

‘Ozone hole’ may be a warming factor due to wind shifts

First, a clarification; while the AGU calls it an “ozone hole”, it technically isn’t. As NASA says here, it really isn’t a “hole” in the true sense of the word, it is simply a region of reduced O3 concentration that … Continue reading

Study says global warming caused by CFCs interacting with cosmic rays, not carbon dioxide

From the University of Waterloo, an extraordinary claim. While plausible, due to the fact that CFC’s have very high GWP numbers, their atmospheric concentrations compared to CO2 are quite low, and the radiative forcings they add are small by comparison … Continue reading
