It's ironic that a big push to the start of this was Dupont paying for a study at USC to fake the ozone thing so they could protect the freon r-12 patent.

That ball's been snowballing downhill ever since.

How come I haven’t heard a peep about CFCs and ozone hole in the past 5 years? THe USA has converted over to 134a, but not much of SA or China, if I understand correctly has.

Place bets on the next hysteria. My guess is RF or light pollution.
