Global Warming a Scam?

I was listening to no particular radio station the other day, and I overheard the radio host make an unusual proclamation. He stated the global warming is a scam, that puts your money into the hands of corporations just to plant trees. This I did not believe for a second. If anything these new regulations on industries to reduce carbon emissions will just cost corporations their money to follow government law. Carbon emissions are going to happen, you release carbon dioxide everytime you take a breath. Sure we all want a clean planet, but seeing any new changes to create this 'perfect planet' are decades away.
