In Their Own Words

As greenhouse gas levels rise to levels unprecedented in the last 700,000 years, the risk grows of there being a climate cataclysm of unforeseeable magnitude and consequences. Prudence argues for a concerted global effort to bring gas levels back into the historically normal range as fast as possible. Thinking locally, the way for the United States to do its part of the job most cost-effectively would be shut down a large fraction of its coal industry--the dirtier part--and replace that coal-generated electricity with zero and low carbon energy, while keeping overall demand from growing. The answer, in other words, is a combination of conservation, wind, natural gas, and nuclear energy.
