The Ozone Hole is the perfect example of the current climate change debate.
People like to cite that as s reason why the climate change warnings are just more doomsaying and it will not come to pass.
In the 70's when we were first warned, there was a lot of the same arguments - humans didn't do it, it's too expensive to fix it, we can't fix it, we'll just make xxxx worse trying to fix it, it's just political, other countries aren't doing their part so why should we, just throw up our hands and hope......
The Montreal protocol was adopted in 1987.By 2006 there was measurable and consistent repair in the Ozone layer, and it has continued to repair since then.
The doomsday scenario didn't happen - because we spent the money and effort to fix it. And Air Conditioners and fire extinguishers still work.
That doomsday scenario was a walk in the park compared to what we face if we don't address the global greenhouse emissions.
I refuse to just give up. I have grandchildren to think about
