It's just basic common sense science CO2 and other gases that human beings produce cause globalwarming while millions of tons more of the stuff have been produced by millions more human beings over the past century in particular.

I know I have a stupid name, but hey, why not call yourself hug a tree and live in a tent.

Science, tecnology, progress and cars rock. Let's have more.

Common sense says global warming is natural.

Hi merlin wood.

Ignoring the troll, I would say common sense is a bad term to use, but I agree with what you are saying. If CO2 traps heat in our atmosphere we shouldn't release more of it and expect temperature to not change. It seems that the people that warn us about climate change have failed to convince everyone about this.
