Ozone layer showing signs of "recovery" : UN

The Earth’s delicate ozone layer has started to show “signs of recovery,” according to a recent study by the UN.

The study published by the World Meteorological Organization and the UN Environment Programme shows that a 1987 ban on damaging gases is shown to have contributed to the reversal in the concern-causing trend, reported the UN study.

“The phase-out of ozone depleting substances has had a positive spin-off for the global climate because many of these substances are also potent greenhouse gases,” the UNEP said in a statement Wednesday.

“However, the assessment report cautions that the rapid increase in certain substitutes, which are themselves also potent greenhouse gases, has the potential to undermine these gains,” it added.

Rising levels of greenhouse gases could potentially weaken these constructive steps. The success, however, could help in preventing millions of cases of skin cancer and other similar conditions.

“Now for the first time in this report we say that we see indications of a small increase in total ozone. That means recovery of the ozone layer in terms of total ozone has just started,” said WMO senior scientific officer Geir Braathen.

“International action on the ozone layer is a major environmental success story ... This should encourage us to display the same level of urgency and unity to tackle the even greater challenge of tackling climate change,” said WMO Secretary-General Michel Jarraud.
