Not saying I don't think global warming is happening. A look at the NW passage this summer has me pretty convinced. My point is, we don't know nearly enough about what is happening.

I watched a really interesting episode of Nova a couple weeks ago called
Dimming the Sun. The basic summed up version is that, contrails, which are the pollution left behind by planes are dimming the sun and are lowering the temperature on earth. The theory is that our impact on the temperature of the planet is worse then we thought because the contrails are stopping some of the suns natural heat. This was shown when on 9/11 all planes were grounded for 3 days and the temperature of the earth went up all over the planet. If anyone catches that show on TV, I recommend you watch it.
