Mysterious new man-made gases pose threat to ozone layer…

Image Credits: NOAA – National Weather Service – Climate Prediction Center By WUWT Regular “Just The Facts” On the heels of Andrew Dessler’s Ozone Hole tweet, we have from the BBC: “Researchers from the University of East Anglia have discovered evidence of four new gases that can destroy ozone and are getting into the atmosphere…

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 CFC’s, but Andrew Dessler’s comment speaks to the hero syndrome some of these scientists seem…

Busted messaging: CFC’s cause warming AND cooling

From the make up your freaking minds department comes this oopsy juxtaposition of alarmist messaging. In an attempt to explain “the pause”, researchers are now grasping for explanations: Human actions that were not intended to limit the greenhouse effect have had large effects on slowing climate change. The two world wars, the Great Depression and…

‘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 periodically changes in size, shape, and density.  -Anthony Ozone hole might slightly warm planet AGU…

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 to CO2. This may be nothing more than coincidental correlation. But, I have to admit,…
