In past decades and in association with a continuing global industrial development, the global atmospheric concentration ofcarbondioxide has been rising. Among the many predictions made concerning this disturbing trend is global warming sufficient to melt polar ice-caps thereby dramatically altering existing shorelines. This book will help fill an obvious gap in the carbondioxide debate by substituting date for speculation. * * Includes contributions from leading authorities around the world * Serves as a companion to CarbonDioxide and Terrestrial Ecosystems * The first book of its kind to explore evolutionary responses of both populations and communities to elevated carbondioxide
