Global Warming

i really cant tell if its a problem or not. Before you flame me or disagree or whatever, Im trying to say that i dont really know if its something that we should just turn our attention to and drop everything else. This past year, it seems as though a lot of little organizations have popped up trying make the world a bit more "greener," even AIM made some kind of computer generated account called "Liv Green" who tells u about facts on global warming or something...All in all though, it doesnt seem like THAT big of a problem...I think it should be fixed in the coming years though.

I know about the greenhouse effect and that certain things like aerosol and old refrigerators can help global warming, but I've also heard that global warming might be a natural effect...After all, Venus went through a global warming period...venus is the most !@#$%& up planet in our solar system, but still.
