Dr James Hansen, the world's leading scientist on climate issues, speaks out for the first time with the full truth about global warming: the planet is hurtling to a climatic point of no return. Hansen - whose climate predictions have come to pass again and again, beginning in the 1980s when he first warned US Congress about global warming - is the single most credible voice on the subject worldwide. He paints a devastating but all-too-realistic picture of what will happen if we continue to follow the course we're on. But he is also a hard-headed optimist, and shows that there is still time to take the urgent, strong action needed to save humanity.
Perhaps best known for bringing global warming to the world's attention in the 1980s when he first testified before Congress, Dr. James Hansen is considered the world's leading climatologist. The head of NASA's Goddard Institute for Space Studies, he served as Al Gore's science advisor for An Inconvenient Truth. He teaches at the Department of Earth &Environmental Sciences at Columbia University, lectures at universities and other institutions throughout the world and has been interviewed in the New York Times and other publications. This is his first book.
