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 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…

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…

Natural Variability in the Widths of the Tropics

Guest Post by Willis Eschenbach In my previous post, “Does This Analysis Make My Tropics Look Big?“I discussed a paper called “Recent Northern Hemisphere tropical expansion primarily driven by black…

Does This Analysis Make My Tropics Look Big?

Guest Post by Willis Eschenbach There is a new paper in Nature magazine that claims that the tropics are expanding. This would be worrisome because it could push the dry…

Oh, Canada!

From Penn State: Environment Canada cuts threaten science, international agreements Recent cuts to the scientific workforce of Environment Canada, a government agency responsible for meteorological services and environmental research, threaten…

D'Aleo on ozone hole: "It is very likely to have been there forever"

Ozone holes in Antarctic and Arctic relate to cold rebounds from warming events By Joseph D’Aleo, Weatherbell.com The ozone hole above the Antarctic has reached its maximum extent for the…

Ozone hole "…caused a great deal of the climate change that's been observed"

Columbia engineering study links ozone hole to climate change all the way to the equator First time that ozone depletion is shown to impact the entire circulation of the southern…

Arctic Ozone "Hole" in March

From the European Space Agency, a story of significant cold and wind patterns that have created an ozone “hole” in the Arctic where there normally isn’t one. The last time…

New rate of stratospheric photolysis questions ozone hole

By Joseph D’Aleo, CCM, AMS Fellow   Dr. Will Happer of Princeton wrote “The Montreal Protocol to ban freons was the warm-up exercise for the IPCC.  Many current IPCC players…

Antarctic Ozone Hole smallest in five years

  From MSNBC: WELLINGTON, New Zealand — International efforts to phase out the use of chlorofluorocarbons and other ozone-depleting substances may be paying off, according to research revealed Friday by the…
