"...I believe it was the mid 1980s and the bans were in place."

The US implemented the Montreal Protocol using the 1990 amendments to the Clean Air Act. The CFC regs are in 40 CFR 82.

I completely agree with oil pan. The CFC regs were a knee jerk reaction and have been a complete failure. The US consumer paid through the nose and got no benefit whatsoever. We have no reason to believer the global warming thing is any different.

Now these guys tell us its too late. OK. Don't worry about it. We'll adapt. Adaptation is what humans are really good at.
