I think that people that are still clinging to the idea that we're affecting the climate are plain wrong. Even Bush is now admitting to it...
To say that for every study saying one thing, there's another saying the opposite isn't quite correct. It's definitely not a 1-1 ratio here.
That being said, it's supremely arrogant to look at the data and affirm to know what's going to happen in 50-100 years. The climate models have huge margin of errors built in and much of the data that is fed into them also has large margins of error.
The alarmists are also playing people for idiots when they talk of flooding cities, countries disappearing etc... Countries like the Netherlands have already been dealing with these problems for a long time. I think we have a pretty good idea on how to build dikes. Heck in HK, we certainly know what land reclamation means...
Unfortunately, I firmly believe that we're too stupid and greedy as a race to do something significant enough to change the current course. Humans will have to lean to adapt to the change and that's as simple as that... It doesn't mean that we shouldn't try to minimize the damage. We should try to lower emissions and become more efficient but the reality is that most people will not care until hit hits their wallet or their lives directly.
The highest selling vehicles in the US for the last 17 years were always pick-up trucks, now it seems the Civic has surpassed it for the first time. Quadruple the price of gas and we might get somewhere...
