Big oil is feeling the heat (if you will) on global warming thanks to Al Gore's new film An Inconvenient Truth. They have launched a laughable attempt to clean up the battered reputation of Carbon Dioxide.
Poor Carbon Dioxide, so misunderstood. You may think its harmful, what with massive quantities being released into the air and causing Global Warming and all. When really CO2 is the most kind and helpful of gases, a vital part of the cycle of life. Leave poor Carbon Dioxide alone. Go pick on Carbon Monoxide. That's some nasty stuff. And also produced by burning oil.
