Trillions of mirrors launched into space to deflect the sun's rays. A massive fleet of ships churning up sea spray to increase Earth's cloud cover. As political responses to climate change limp along, scientists currently are debating these and other geoengineering schemes to stabilize the climate. Yet, as many have observed, such schemes carry formidable costs--and risks.
The United States must begin immediately retooling its economy to build a low-carbon, environmentally sustainable future, which in turn can strongly influence the global economy and geopolitics. With the production and consumption of energy the largest component of the U. S. economy in terms of both the flow of money and the movement of goods, this task will require a well-coordinated, interdisciplinary focus across federal and local governments and the private sector. Our current reliance on fossil fuels--the annual U.S.
