Ozone Recovery Stalled


The risk of skin cancer is about to rise in countries like Australia, New Zealand, Argentina and Chile. A study busts the myth that global warming does not affect ozone recovery. Greenhouse gases bring about changes in wind patterns. The study shows that global warming has caused air circulation in the stratosphere (ozone layer) to increase in countries in the southern hemisphere. Quicker the air moves through the ozone layer, slower the ozone gets formed thus stalling its recovery. The projections also revealed that countries in the northern hemisphere will be least affected. More studies are required to measure the varying impacts of global warming on countries across the globe. The study was published in the February issue of Geophysical Research Letters.
