So carbon dioxide is now considered an explosive and people have been arrested for possessing it. Seems to me we should label global warning as a terrorist activity and waterboard the CEO's of Exxon/Mobil and other polluters to teach them the error of their ways. After all, those guys make more carbon dioxide than anyone else!
