A paper unifying cosmic ray interaction, CFC's ozone, and warming

On Cosmic-Ray-Driven Electron Reaction Mechanism for Ozone Hole and Chlorofluorocarbon Mechanism for Global Climate Change Qing-Bin Lu, Department of Physics and Astronomy, University of Waterloo Abstract Numerous laboratory measurements have provided a sound physical basis for the cosmic-ray driven electron induced reaction (CRE) mechanism of halogen-containing molecules for the ozone hole. And observed spatial and…

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 nasty thunderstorms wot done it.  They say: “Recent studies have suggested that the number and intensity of such storms are linked to climate changes…which could…

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 carbon and tropospheric ozone”, by Robert Allen et al, hereinafter A2012. They use several metrics to measure the width of the tropics—the location of the…

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 zones further north and south, moving the Saharan aridity into Southern Europe. The paper is called “Recent Northern Hemisphere tropical expansion primarily driven by black…

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 scientific research related to the ozone layer in the upper atmosphere and pollution in the lower atmosphere, according to environmental scientists in the U.S. These…

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 this happened was in 1997. It isn’t really a “hole” as you can see in the graphic below there are reduced levels of ozone, but…

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 gained fame then by stampeding the US Congress into supporting the Montreal Protocol. They learned to use dramatized, phony scientific claims like “ozone holes over…

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 National Institute of Water and Atmospheric Research in New Zealand. The Antarctica ozone hole is the smallest it has been in the past five years,…
