Well, this is going to be a heartbreaker for the hysterical global warming crowd. According to a new study, emissions from burning corn are worse for the environment and produce more CO2 or ‘global warming’ gases than the burning of traditional gasoline.

A $500,000 study paid for by the federal government and released Sunday in the peer-reviewed journal Nature Climate Change concludes that biofuels made with corn residue release 7 percent more greenhouse gases in the early years compared with conventional gasoline.
