Climate Change and the Ozone Layer: Lessons from Montreal

You may remember not so long ago the hole in the ozone layer was
the major scientific apocalypse story out there in the world. It
could have proved devastating for society, but - after the
Montreal protocol banned and heavily regulated the substances
that were causing the problem, the ozone hole has begun to shrink
and the crisis has died down.

In this episode, I'll talk about the story of the ozone hole and
what - if anything - it can teach us about our own efforts to
combat greenhouse gas emissions and climate change.
