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:…
Asian ozone pollutes Hawaii and USA west coast – varies with climatic shifts
Asian ozone pollution in Hawaii is tied to climate variability (Nature Geoscience) By Joanne Curcio, Program in Atmospheric and Oceanic Sciences Air pollution from Asia has been rising for several…
At AGU, NASA says CFC reduction is not shrinking the ozone hole – yet
NASA Reveals New Results From Inside the Ozone Hole – Dec. 11, 2013 NASA scientists have revealed the inner workings of the ozone hole that forms annually over Antarctica and…
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…
'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,…
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,…
Who would have guessed it? Sunlit snow key to Arctic ozone depletion
I like this study from the NSF, because they did hands-on empirical measurements and experiments to make the determination – Anthony Sunlit Snow Triggers Atmospheric Cleaning, Ozone Depletion in the…
Ozone hole in Antarctica shrinks significantly, but not a record low as erroneously reported elsewhere
While this is good news any way you look at it, I note there are a number of news reports saying that the “Ozone Hole Shrinks to Record Low” which…
Ozone depletion trumps greenhouse gas increase in jet-stream shift
From Penn State UNIVERSITY PARK, Pa. — Depletion of Antarctic ozone is a more important factor than increasing greenhouse gases in shifting the Southern Hemisphere jet stream in a southward…
Good news: 2012 Antarctic Ozone Hole is the second smallest in 20 years

There might possibly could be a chance of danger! Thunderstorms!
Guest Post by Willis Eschenbach Thunderstorms are one of my main interests, so I read up on a study by some Harvard researchers that has been receiving all kinds of…
Climate change – off in the ozone
From the Harvard University news service and the what are they smoking department, comes this suggestion that apparently it never was ozone damaging CFC refrigerants at all, it was those…
Shocker: The Hansen/GISS team paper that says: "we argue that rapid warming in recent decades has been driven mainly by non-CO2 greenhouse gases"

Ozone layer discovered on Venus
From the European Space Agency: ESA finds that Venus has an ozone layer too ESA’s Venus Express spacecraft has discovered an ozone layer high in the atmosphere of Venus. Comparing…
Arctic cold yields "unprecedented Arctic ozone loss"
“What was different about this year was that the temperatures were low enough to generate ozone-depleting forms of chlorine for a much longer period of time.” And it is worth…
