International efforts to reduce harmful emissions into the atmosphere, necessary to destroy the Earth's protective ozone layer, yielding first results. As scientists have found in New Zealand, the width of the ozone hole over Antarctica is slowly decreasing.
According to the measurements, the ozone layer will return to the state in which he was in the 198th year, by the 2050, if all the measures to control greenhouse gas emissions will continue.
The width of the ozone layer in the stratosphere is only 25 km, but it plays an important role in protecting the earth from solar radiation. His thinning caused a surge of disease in humans and many environmental problems around the world, but especially in the southern hemisphere. Though ironically, the main emissions produced just the opposite of the Northern Hemisphere.
Thin ozone layer has changed direction and strength of air flow over Antarctica. Warmer air would often come to the Antarctic Peninsula, causing its active melting. In contrast, in the rest of the Antarctic Ozone protection observed cooling of the climate. So when you restore the ozone layer and the background of the general warming of the modeling of weather and melting ice in Antarctica will become even more difficult.
It is too early to predict exactly when the ozone layer over the South Pole will be back to normal, but received good news can not but encourage and inspire more daring exploits in protecting the planet's ecology.
