In a new study published in Science magazine, US researchers on Thursday said the hole in the ozone layer over Antarctica is a major driver of climate change and rain increases in the southern hemisphere over the last 50 years.

In a study to be published in the April 21st issue of Science magazine, researchers at Columbia University's School of Engineering and Applied Science report their findings that the ozone hole, which is located over the South Pole, has affected the entire circulation of the Southern Hemisphere all the way to the equator.

Over the past few days ozone-depleted air masses extended from the north pole to southern Scandinavia leading to higher than normal levels of ultraviolet (UV) radiation during sunny days in southern Finland.

Scientists with the United Nations (UN) announced Thursday they found that the Earth’s protective ozone layer in the upper atmosphere has stopped thinning out and should be mostly restored by the middle of this century thanks to a ban on dangerous chemicals that float up into the air.

Scientists using European Space Agency satellite data say they've discovered the depletion of the Earth's ozone layer might be easing. We found a global slightly positive trend of ozone increase of almost 1 percent per decade in the total ozone from the last 14 years: a result that was confirmed by comparisons with ground-based measurements, said Diego Loyola, who worked on the project with colleagues from the German Aerospace Center. Ashley Jones and Jo Urban from Sweden's Chalmers...

By merging more than a decade of atmospheric data from European satellites, scientists have compiled a homogeneous long-term ozone record that allows them to monitor total ozone trends on a global scale – and the findings look promising.

Canadian scientists say climate change will lead to less ultraviolet radiation in some northern areas, such as Siberia, Scandinavia and northern Canada. Physicists at the University of Toronto said they have discovered changes in the Earth's ozone layer due to climate change will reduce the amount of ultraviolet radiation in northern high latitude regions, while other areas of the Earth, such as the tropics and Antarctica, will instead face increasing levels of UV radiation. Using a...
