When the Arctic ice pack was first measured in the 1950s, it averaged 30 feet thick in midwinter. By the end of the century it was down to 15. One August the ice broke. The next year the breakup started in July. The third year it began in May. That was last year.

It's an increasingly steamy summer in the nation's capital as Senate environmental staffer Charlie Quibler cares for his young son and deals with the frustrating politics of global warming. Charlie must find a way to get a skeptical administration to act before it's too late-and his progeny find themselves living in Swamp World. But the political climate poses almost as great a challenge as the environmental crisis when it comes to putting the public good ahead of private gain.

While Charlie struggles to play politics, his wife, Anna, takes a more rational approach to the looming crisis in her work at the National Science Foundation. There a proposal has come in for a revolutionary process that could solve the problem of global warming-if it can be recognized in time. But when a race to control the budding technology begins, the stakes only get higher. As these everyday heroes fight to align the awesome forces of nature with the extraordinary march of modern science, they are unaware that fate is about to put an unusual twist on their work-one that will place them at the heart of an unavoidable storm.
