Technology Review is sunnily confident that technology is the single greatest force for expanding human possibilities. But honesty compels us to confess that technology has created the prospect of catastrophic climate change. Technology, too, must provide a solution.

Rather than waiting for futuristic alternatives like the much-bruited "hydrogen economy," the nations of the world could begin to control the growth of greenhouse-gas emissions today. What is lacking is any considered strategy.
