Is Global Warming caused by CO2?

Copenhagen summit is still going. Many disagreements between developing and developed countries have increased the difficulty to reach an agreement in this summit.

I still doubt that how many politicians really concern this issue even when they went to attend this COP15-Copenhagen summit.

In the mean time, I do have question about the importance of CO2 vs. global warming. I totally agree that we should try all we could do to save energy, reuse, reduce, recycle, protect our environment, change our lifestyle to much more environmental friendly way, etc. I have been promoting these for the past 20 years and I have taken action in my daily life. It is dangerous to just blame this "global warming problem" to a single factor, CO2 (and greenhouse gases). The reason that I put "greenhouse gases" inside () is because that people have emphasized CO2 so much that other greenhouse gases have been ignored relatively.
