What? Talk about apples and oranges!
The ozone hole was a WELL documented result of CFCs (and some other chemicals). There was no doubt. The chemicals were, in fact and beyond all argument, depleting the ozone layer. The hole had grown significantly and was getting bigger. The impact would, without doubt, be seriously bad. We stopped the CFCs, the hole stopped growing. It has since moved towards the equator and is splitting into two pieces. The depletion is not finished screwing us. The effects continue and will continue into the forseeable future. Were it not for us stopping the CFCs, we woulda definately had a damn big problem on our hands.
Global warming must be evaluated in regard to the amount which is anthropogenic, and one must determine the impact of CO2 within many other significant gasses. There is argument about AGW in the first place (I go with 10-30% anthropo), how much CO2 is involved in the long term, what other factors are involved, our ability to influence the event even if we have been contributing significantly... and just about every other aspect of global warming.
Comparing the ozone hole and CFCs (in the US, we waited for real proof) and global warming and CO2 (in the UN, where hysteria is the name of the game) is comparing apples and oranges.

Of course Teddy (national parks) and Dick (clear water or air, Engangered Species Act and EPA) are the top 2.
Who did the sulfur regs with cap and trade? That was Reagan? It was a resounding success. After we set the cap and trade into affect, we discovered technology that greatly reduced sulfur emissions, quickly rendering the C&T system for sulfer obsolete and the industry spanky clean. Perhaps the discovery of the tect was not related to the C&T program, meh, what happened happened.

I think the next big enviro president will not be because of energy. It will be the one that deals with the farm bill and agriculture... moving towards a de-centralized and ecologically healthy system of sustainable food production and marketing.
