.....I have my own whacked out theories:
- Cow Farts: you bet those bovines are blowing a lot of gas!

- Volcanoes: Let's see Al Gore put a stop to them!
- Fat People: Too many fat people & they're all breathing, expelling Carbon Dioxide!

- Hippies: They stink & they pollute!

- Terrorists, etc.: All this blowing up stuff & people HAS to have some effect

- Politicians: Blowing out hot air beyond Mother Nature to handle!

- Beer & Soda: burping all that Carbon Dioxide

.....and while we're at it let's just blame lots of other things like Bar-B-Ques, composting, sex (all that heavy breathing you know), making diecast airplanes, lawn mowers, light bulbs, eating meat, eating vegatables, eating anything...

.....I think the funniest new theory on "Global Warming" blames the incandescent light bulb. The "experts" say we should all convert to CFB (compact flourescent bulbs). Now what any of you want to bet 10 years from now when all these CFBs are wearing out and being disposed of that these same "experts" will be howling about the pullution caused by these CFBs.

.....I'm having none of "global warming". It's climate change and has happened several times just in recorded Human history. Greenland was called that because it was green and Norse settlers did quite well there with farms. There were vineyards as far north as Scotland. That all changed and the world went through a "mini-ice age" that lasted more than 500 years (into the early 1800s).
.....Not worried about planes. Heard it before. Yeah, the Concorde was going to destroy the ozone layer. Seems to still be there.
