There will be a point where we can directly influence the warming or cooling of this planet in the not too distant future. This though is not what bothers me, but what it will do to our somewhat mild weather is what bothers me. Tornados, Hurricanes, Flooding, Freezing, You name it, it's all about to get screwed up. I personally don't think we had much influence on the polar ice caps however. The Earth is going to go through cycles whether we are here or not. We may help nudge it one way or another, but overall, we are at it's mercy, SUV driving or not.
Why? Planets are also warming up in our solar system at this very moment. Pluto is even warming up right now. So is Jupiter. Something much bigger than us is the cause.
