The NSIDC and many other used the ozone hole as an “excuse” for why Antarctic Sea Ice Extent broke records this year.
“Both warming and ozone loss act to strengthen the circumpolar winds in the south. This is due primarily to persistently cold conditions prevailing on Antarctica year-round, and a cold stratosphere above Antarctica due to the ozone hole. Stronger winds generally act to blow the sea ice outward, slightly increasing the extent”
Guess what, WUWT tells us it was the 2nd smallest ozone hole in 20 years.
“The average area covered by the Antarctic ozone hole this year was the second smallest in the last 20 years, according to data from NASA and National Oceanic and Atmospheric Administration (NOAA) satellites.”
What a shock. The “scientists” excuses for more Antarctic Sea Ice was bogus.

Causation has not been demonstrated by the “proven data” about CO2 touted by AGW crowd. In fact the previously cited correlations used in the models have not predicted subsequent trends. There has been a far better model proposed related to chlorofluorocarbons (CFC’s) impact on cosmic radiation indicated by the ozone hole which supports the temperature trends seen over the last 15+ years

Ozone holes are localized and seasonal events and they do not constitute evidence of ozone depletion on a global scale as claimed by the UNEP in the Montreal Protocol. Please see
