This year's ozone hole could be the smallest it has been in 30 years

Inhabitat - Innovation

For decades, scientists have closely observed the ozone layer, which protects Earth from the sun's harmful ultraviolet (UV) radiation. This year, just in time for World Ozone Day, the European Union's Copernicus Atmosphere Monitoring Service (CAMS) announced the state of the ozone hole — its size is the smallest it has been in the past 30 years

We’ve got another ozone problem, and it’s not what you think


Most of us know ozone as that benevolent stratospheric layer that absorbs the sun’s harmful UV light and keeps us safe. In the 1980s, scientists found a “ hole ” in the ozone layer — really just a large section that was getting precariously thin — caused by the use of potent chemicals called CFCs. But the beneficial ozone up in the stratosphere has an evil cousin, and it’s right here on the ground. Ozone increases with more sunshine, heat waves, and so forth.”.
