Haha, you'll get in trouble with the enviro-nuts with a post like that!
NASA had an interesting article a few years ago relating to solar relationships and Earth's climate. It got buried. But, the gist of it is that because of this little thing called gravity, whenever Jupiter and Saturn are near each other in their orbits around the sun, it pulls the sun harder towards them, since both the gas giants' collective mass is enough to do this. Actually, all the planets effect the sun's position to some extent, but only the two big boys have the most pull, and when they are close to each other with relation to their orbit (as opposed to being on opposite sides of the sun) they cause this phenomenon of hyper weather patterns on Earth. Because of Earth's relatively fast orbital speed, when Jupiter and Saturn are close, we get "squeezed" closer to the sun when we pass between the sun and the gas giants, and get slung out further when we are on the opposite sides. This difference is enough to change things pretty much.
Guess where Jupiter and Saturn are right now?

And they are getting closer, because Jupiter, closer to the sun, orbits faster, and is catching up to Saturn. Since these planets orbit so slowly relative to the Earth, these effects last for a long time. Not just one season.
Jupiter takes almost 12 years to orbit the sun.
Saturn takes almost 30 years.
Do the math (or find a neat animation, they are out there) and you can see that there is a LOT more to climatology than just mankind. That said, I still think doing everything we can within our technological limits while providing a decent way of life and not being wasteful just because it is convenient to do so is a good thing.
