Earth's protective ozone layer (click here) is finally healing from damage caused by aerosol sprays and coolants, a new United Nations report said.
The ozone layer had been thinning since the late 1970s. Scientist raised the alarm and ozone-depleting chemicals were phased out worldwide....
The planetary ozone is showing sustained improvement. I will remind all this was discovered by science conducted in Antarctica. The planetary ozone is healing because the international community took scientists seriously and abided by an international treaty that ended the abuses of a particular type of greenhouse gas. We explored all those over the past two years.
If an international community can heal an ozone layer, it can heal the currently hot troposphere. We can achieve a rollback of all greenhouse gases and ultimately have zero emissions.
We can do this. It is proven we can.
