Possibly the most graphic treatment of global warming that has yet been published, <i>Six Degrees</i> is what readers of Al Gore's best-selling <i>An Inconvenient Truth</i> or Ross Gelbspan's <i>Boiling Point</i> will turn to next. Written by the acclaimed author of <i>High Tide,</i> this highly relevant and compelling book uses accessible journalistic prose to distill what environmental scientists portend about the consequences of human pollution for the next hundred years. <br><br>In 2001, the Intergovernmental Panel on Climate Change (IPCC) released a landmark report projecting average global surface temperatures to rise between 1.4 degrees and 5.8 degrees Celsius (roughly 2 to 10 degrees Fahrenheit) by the end of this century. Based on this forecast, author Mark Lynas outlines what to expect from a warming world, degree by degree. At 1 degree Celsius, most coral reefs and many mountain glaciers will be lost. A 3-degree rise would spell the collapse of the Amazon rainforest, disappearance of Greenland's ice sheet, and the creation of deserts across the Midwestern United States and southern Africa. A 6-degree increase would eliminate most life on Earth, including much of humanity. <br><br>Based on authoritative scientific articles, the latest computer models, and information about past warm events in Earth history, <i>Six Degrees</i> promises to be an eye-opening warning that humanity will ignore at its peril.
