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 … 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

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 direction, according to researchers at Penn State. “Previous research suggests … Continue reading

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 … Continue reading

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 … Continue reading

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” … Continue reading
