Do you think Global Warming is just another money making scheme?

I had heard (no facts, just rumor (rumour)!) that Al Gore and some certain select uber-rich individuals are investing in all these Global Warming related business, i.e. business whose sole product is granting carbon credits to other businesses for cash as well as other "Green" initiatives. I do find this all extremely possible as in my opinion "all" politicians are crooks to one level or another. With the kind of media availability these politicians have they could sell ice water to eskimos given the right wonky story. Your ideas folks? Is it really doom and gloom or let's take all their money and put them under our power?
