Back off, Sucka! :p
Go back and reread what I wrote. The only thing I said about the ozone layer was it's way up there. [add edit] I also briefly explained it's benefit.
Everyone is well aware of the problem with chlorinated fluorocarbons and how that was addressed....it appears successfully.
Then I was describing the ozone that you hear about on the news all the time, that's associated with smog. You know, smog, ground level, Los Angeles, polution....nothing to do with the ozone layer.
Now, as for warming, I think the fact that the glaciers are no longer in PA is a pretty good indication. The glaciers have advanced and retreated for a long time.
bluesdave, I asked how much is the CO2 we produce, contributing to the speed of the increase, and will it push the increase higher than it would in a normal cycle?
I realize there's a shitload of stuff we don't know about how mother nature works. I also realize people are having an impact in a million different ways from cutting down trees to burning oil/coal to raising millions of methane producing cattle. The problem is figuring out what does how much and is their a better way. A simple cost/benefit relationship.
Say for instance, they decide that if everyone lives in a cave with no electricity or central heat, the average temperature will go to X instead of X+1, and it will go back down a year sooner. Not worth it
Now same scenario, but X+1 would cause 90% of the Earth to be unable to produce food for 10 years. Solient Green makes a big difference, no?
Of course by the time we get most of it figured out, it'll be over, but I think we should concentrate on what produces the most bang for the buck/effort/sacrifice.
Probably not mowing lawns and Golf courses would be a help, but there are consequences that people would object to, without knowing how much it would help the overall effort. Reasonable people don't want feel good programs that are of no real benefit.
