Ten of the nation’s largest companies, including Caterpillar and former Global Climate Coalition [3] member, Duke Power [4], say they now want Congressional legislation to limit climate change--including at least a 10 percent annual national decline in carbon dioxide emissions. A Sierra Club [5] spokesman offered hope that the companies will “throw not just their messaging weight but their political weight behind [the call for legislation].” Thomas Tanton, Institute for Energy Research [6] vice president and global warming skeptic [7], called the turnabout a “good defense" against more stringent regulation. "Something less bad is better than something really bad.” How will Congress respond? Reporters for the Washington Post suggest that there is a “Harry and Louise”-type [8] political ad by industry lurking to scare away innovation-driven legislators. “If you’re a Democrat in a moderate district, this is not the kind of vote you want to take,” Myron Ebell of the Competitive Enterprise Institute [9], another industry-supported group, told the Post.
