    The Antarctic ozone hole varies from year to year (depending on winter and spring circulation patterns in the stratosphere), toward a slowly shrinking hole since the Montreal Protocol went into effect. However, 2011 was not a good year with a sprintime max of 23 million sq km, and depth of 95 DU.

    Of interest, in spring 2011, the largest Arctic hole ever developed, again, due to unique circulation patterns.

    Thanks for that Meteor Wayne ,So what we still have is a great big hole. Should we not be highlighting the problem,keeping its importance paramount.
    Instead we never here of it these days, on the news.

    Personally, I'm not sure that more publicity for this particular issue is an unalloyed good.

    Far too many people get the ozone issue confused with global warming. Haven't seen so much of that lately, presumably because of the lack of publicity.

    Though the apparent, but unreliable, stabilising and frequent downward ticks in size are a good thing. My preference is for this to be used as an example of the fact that international cooperation on such issues can work - but even when we get emissions (of whatever is the atmospheric issue in question) under control, that it still takes a very, very long time for the benefits of that action to flow through the system to a consistent measurable result.
