<P>The research paper "Extinction Risk from Climate Change" published in the journal <I>Nature</I> in January 2004 created front-page headlines around the world. The notion that climate change could drive more than a million species to extinction captured both the popular imagination and the attention of policy-makers, and provoked an unprecedented round of scientific critique.<br> <br><I>Saving a Million Species</I> reconsiders the central question of that paper: How many species may perish as a result of climate change and associated threats? Leaders from a range of disciplines synthesize the literature, refine the original estimates, and elaborate the conservation and policy implications.<br>The book: <UL> <LI>examines the initial extinction risk estimates of the original paper, subsequent critiques, and the media and policy impact of this unique study <LI>presents evidence of extinctions from climate change from different time frames in the past <LI>explores extinctions documented in the contemporary record <LI>sets forth new risk estimates for future climate change <LI>considers the conservation and policy implications of the estimates. <p></P></LI></UL> <p><I>Saving a Million Species</I> offers a clear explanation of the science behind the headline-grabbing estimates for conservationists, researchers, teachers, students, and policy-makers. It is a critical resource for helping those working to conserve biodiversity take on the rapidly advancing and evolving global stressor of climate change-the most important issue in conservation biology today, and the one for which we are least prepared.</p>
