Everybody is so bent on taking an extreme stance of "CO2 is causing all global warming!", or "we're not causing any of it! Lets fire up the hummer!"

The science in how CO2 captures and increases heat in the Earth's atmosphere is solid; it just can't nearly account for the whole process. Yes the solar system is heating up; that doesn't necessitate SUV's on Mars to validate man-made global warming. You guys speak as though man-made GW proponents have never heard this most basic argument. Few even consider the notion that *gasp* it's due to a multitude of factors. Personally I'm guessing that CO2 emissions are responsible for somewhere around 15% of it all, but as I must emphasize, that's a guess.


Personally I'm more worried about the other greenhouse gas. It's more heat-trapping and more abundant than even CO2. Can anybody guess what it is? Water vapor!
