Ever since 9/11, many have considered al Queda to be the leading threat to global security, but falling water tables in countries that contain more than half the world’s people and rising temperatures worldwide pose a far more serious threat. Spreading water shortages and crop-withering heat waves are shrinking grain harvests in more and more countries, making it difficult for the world’s farmers to feed 70 million more people each year. The risk is that tightening food supplies could drive up food prices, destabilizing governments in low-income grain-importing countries and disrupting global economic progress. Future security, Brown says, now depends on raising water productivity, stabilizing climate by moving beyond fossil fuels, and stabilizing population by filling the family planning gap and educating young people everywhere.

Our most widely respected environmental writer brings together the essential voices on global warming, from its 19th-century discovery to the present With the rise of extreme weather events worldwide–witness the devastation wrought by Hurricanes Sandy, Irene, and Katrina, and the sustained drought across the American West–global warming has become increasingly difficult to deny. What is happening to our planet? And what can we do about it? The Global Warming Reader provides more than thirty-five answers to these burning questions, from more than one hundred years of engagement with the topic. Here is Elizabeth Kolbert’s groundbreaking essay “The Darkening Sea,” Michael Crichton’s skeptical view of climate change, George Monbiot’s biting indictment of those who are really using up the planet’s resources, NASA scientist James Hansen’s testimony before the U.S. Congress, and clarion calls for action by Al Gore, Arundhati Roy, Naomi Klein, and many others. The Global Warming Reader is a comprehensive resource, expertly edited by someone who lives and breathes this defining issue of our time.

More than a warning, Earth under Fire is the most complete illustrated guide to the effects of climate change now available. It offers an upbeat and intelligent account of how we can lessen the effects of our near-total dependence on fossil fuels using technologies and energy sources already available. A thorough revision and a new preface for the paperback edition bring the compelling facts about climate change up to date.

A new article in the medical journal The Lancet has concluded much of the Northern Hemisphere will be too hot by 2085 to host the Summer Olympics. Researchers are projecting only

Earth’s record hottest 12 consecutive months were set in each month ending in September 2015 through May 2016 2014 and 2015 each set the record for hottest calendar year since we began measuring surface temperatures over 150 years ago, and 2016 is almost certain to break the record once again. It will be without precedent: the first time that we’ve seen three consecutive record-breaking hot years.
