Critique of "Global Hysteria"

An article I recently read at Fox Forum explains in detail the thought that global warming is nothing more than a way to redistribute global wealth. The author claims that global warming is a scam that was produced so he legislation could be produced favoring greener technologies, this favoritism of policy will lead to an transfer of wealth away from big oil. The author uses as his credibility the new budget plan proposed by Obama that offers healthy tax credits for carbon emissions these can be bought by companies that produce large amounts of carbon or sold by companies that do not produce these emissions.  The author uses a foreboding tone the entire piece which serves to highlight the general darkness of our future if we continue on this path, also the author seem to be very instant that there is no global warming at all. Overall i do agree with the author on this matter I think the piece is a bit ineffective at reaching the targeted audience of older politically active readers that need a less biased article to make an informed decision.
