Some amusing non-news about ozone
Here it is, right from the horse's mouth, the horse being the summary in the official WMO report which is giving a lot of Greenies erections at the moment. Im my usual pesky way I went back to the original science rather than accepting journalistic spin about it. Read it and see whether you think there is anything notable in it:
Total column ozone declined over most of the globe during the 1980s and early 1990s (by about 2.5% averaged over 60°S to 60°N). It has remained relatively unchanged since 2000, with indications of a small increase in total column ozone in recent years, as expected. In the upper stratosphere there is a clear recent ozone increase, which climate models suggest can be explained by comparable contributions from declining ODS abundances and upper stratospheric cooling caused by carbon dioxide increases.
The Antarctic ozone hole continues to occur each spring, as expected for the current ODS abundances. The Arctic stratosphere in winter/spring 2011 was particularly cold, which led to large ozone depletion as expected under these conditions.
Far from ozone declining, the finding is a small INCREASE in the amount of ozone overhead. And the Antarctic ozone hole apparently shows no trend other than what can be attributed to recent COOLING. (Where's that global warming gone?)
I would have thought that the findings were a total disappointment to the Greenies and their Montreal Protocol but they are manging somehow to spin it in a way that keeps their spirits up.
The spin that the Warmists are putting on it is that the ozone "hole" has stopped growing. But how can they know that? The hole is highly variable from year to year and it could very easily roar back overnight bigger than ever. Warmists really are a sad bunch.
