It's not often that I see a headline story and put in a comment, but this one is a case of Beware of Greeks bearing gifts
. The UN are congratulating the human race for saving the world from an expanding ozone layer made from "Man Made" pollution. They (the UN) do not mention any solar influence in this statement, as that would not fit in with the "Man Made" theory. The fact is during the past few years our Sun has had a dramatic transformation, in that, there has been a virtual halt to the Sun's higher then average sunspot activity that we have seen in recent years. This spurious analysis of the ozone layer by the UN makes an interesting conclusion, a reduction of "Man Made" pollution reduces the output of the Sun. The conclusion from yours truly says a reduction of the output of the Sun results in a smaller ozone area, but who wants to know that! I'm sure WUWT will have something to say on this, hopefully the same and more.
LEADING scientists say the ozone layer is starting to repair itself and will eventually give us much greater protection from skin cancer.
They say that phasing out almost 100 substances once used in such products as refrigerators and aerosols has stopped the layer from further depletion.
Ozone in the stratosphere is important because it absorbs most of the sun’s dangerous ultraviolet radiation, which can lead to skin cancer and eye damage.
Although it is not yet increasing again, the ozone layer outside the polar regions is, by the year 2048, expected to recover to the levels it was at 30 years ago.
The United Nations report
, Scientific Assessment Of Ozone Depletion 2010, paints a much more optimistic picture than previous assessments and is the first comprehensive update in four years.
It argues that action taken through the Montreal Protocol, which began in 1987 and has introduced the reduction of harmful emissions, has helped to halt the damage.
Achim Steiner, UN under-secretary general and environmental programme executive director, said: “Without the Protocol, levels of ozone-depleting substances could have increased tenfold by 2050.
“This, in turn, could have led to up to 20 million more cases of skin cancer and 130 million more cases of eye cataracts, not to speak of the damage to human immune systems, wildlife and agriculture.”
