Climate Change Cities

From Mayor Michael Bloomberg and former head of the Sierra Club Carl Pope comes a manifesto on how the benefits of taking action on climate change are concrete, immediate, and immense. They explore climate change solutions that will make the world healthier and more prosperous, aiming to begin a new type of conversation on the issue that will spur bolder action by cities, businesses, and citizens—and even, someday, by Washington.

In Extreme Cities, Ashley Dawson argues that cities are ground zero for climate change, contributing the lion's share of carbon to the atmosphere, while also lying on the frontlines of rising sea levels. Today, the majority of the world's megacities are located in coastal zones, yet few of them are adequately prepared for the floods that will increasingly menace their shores. Instead, most continue to develop luxury waterfront condos for the elite and industrial facilities for corporations. These not only intensify carbon emissions, but also place coastal residents at greater risk.

The Agile City engages the fundamental question: what to do about it? Journalist and urban analyst James S. Russell argues that we'll more quickly slow global warming - and blunt its effects - by retrofitting cities, suburbs, and towns. The Agile City shows that change undertaken at the building and community level can reach carbon-reduction goals rapidly. Adapting buildings (39 percent of greenhouse-gas emission) and communities (slashing the 33 percent of transportation related emissions) offers numerous other benefits that tax gimmicks and massive alternative-energy investments can't match.
