ozone layer

What impact these particles have on atmosphere, weather patterns and the ozone layer is still unclear.

Better known as CFCs, these chemicals can destroy the protective ozone layer, thinning it greatly.

It might be hard to imagine now, but in the 1980s the world came together to face down an emissions threat — a “hole” in the ozone layer over Antarctica — and ban the use of aerosols called CFCs that scientists said had caused the problem.

At the same time foul-drawing fell back to earth, shooting accuracy shot through the ozone layer.

They worry that too much smoke could damage the ozone layer, which protects Earth from the sun’s harmful radiation.

Heretics, they'd be burned at the stake if that were not such a bad thing for the ozone layer.
