Good news: no ‘ozone hole’ in the Arctic

From the Massachusetts Institute of Technology Plugging an ozone hole MIT researchers find that the extremes in Antarctic ozone holes have not been matched in the Arctic CAMBRIDGE, Mass– Since the discovery of the Antarctic ozone hole, scientists, policymakers, and the public have wondered whether we might someday see a similarly extreme depletion of ozone…

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…
