I absolutely believe that our climate is warming up. Do I believe I am the culprit? Absolutely not.
Are people making money off of this scam? Absolutely. And if I were morally bankrupt, being the Good Little Capitalist I am, I would be, too.
Anyone that has ever gotten off of their couch and done any amount of traveling around the globe can easily see how vast and mighty Earth is. We are insignificant fleas on the back of Mother Earth. She flicks us off at will on a daily basis...and there is little we can do about it other than not living on a Flood Plain or in Tornado Alley, at Sea Level or on a Fault line.
And even then, if she's gunning for you, you don't stand much of a chance. :)
I would not jump too quickly to that conclusion. Check out the climate data for the US at this location. Look at about 50 locations focusing on small towns if you can. Jot down the direction of the trend line. I think you will be surprised.

Once you have done that go to Steve McIntyre's site
www.climateaudit.org
and explore the Siberian influence on Global Warming. I think you will find the whole exercise worthwhile.
To balance the skeptics out you can visit
www.realclimate.org
These tend to be sites where they discuss data in non-hyperbolic ways.
Good luck.
