"Threat Multiplier takes us onto the battlefield and inside the Pentagon to show how the US military is confronting the biggest security risk in global history: climate change. More than thirty years ago, when Sherri Goodman became the Pentagon's first Chief Environmental Officer, no one would have imagined this role for our armed forces. For much of the twentieth century, environmental protection was a sideshow to military activities. And yet, today, the Department of Defense has moved from an environmental laggard to a clean energy and climate leader, recognizing that a warming world exacerbates every threat -- from hurricanes and forest fires to competition for increasingly scarce food and water to terrorism and power plays by Russia and China. The Pentagon now considers climate in war games, disaster relief planning, international diplomacy, and even the design of its own bases" -- provided by publisher.
