During his inaugural speech, President Obama said, "...we'll work tirelessly to... roll back the specter of a warming planet." Specter is a powerful word to use, imbued with dark magic – a terrifying apparition and unreal appearance, a visible incorporeal spirit. But if the scientific synthesis of Mark Lynas in his new book, Six Degrees: Our Future on a Warming Planet, is correct, then President Obama has chosen his words wisely.
Mark Lynas has written a compelling book – and revealing its basic thesis does not spoil the read because he tells the details so well. Six Degrees is the story of the difference between the world we have now, and our world six degrees warmer. The lesson is simple: the time to act is now! Lynas has compiled and synthesized the work of numerous climate scientists and the Intergovernmental Panel on Climate Change (IPCC). His story unfolds, chapter by chapter, with a scientific description of the change that may occur with each successive degree (Celsius) of global warming.
