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

Grist

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.”.
