Global Warming

For those who think man is the largest contributor to global warming, I ask, "What is the largest (percentage wise) greenhouse gas?" Answer: dihydrogen monoxide, otherwise known as water. The largest contributor? The sun. In the last 60 years, Earth's temperatures have mirrored temperatures on the sun (proportionally, of course). Do a little research, and you find that the sun is the global warming fiend (which, by the way, economists think will help the Earth economy), not humans. Interesting.
