Global Warming

I think that we can agree that we're getting warmer. Is it cyclical or is it caused by human activity? I'm neither a climatologist nor a environmental scientist, so I don't know.

What I really don't get is why this debate has to run along party lines. All that that accomplishes is getting a bunch of people who don't know anything to stand up and recite their party's line. Case in point, stupid Rush Limbaugh says that it can't possibly be caused by human activity because we can't fix it. There you go.
