"The Ages of Gaia: A Biography of Our Living Earth" by James Lovelock.

Mr. Lovelock is a British geophysicist who originated the theory that the world is a self-regulating system that, over the eons, has been able to sustain an equilibrium between hot and cold that supports life. Propelled by global warming, a tipping point has almost been reached beyond which the Earth will not recover sufficiently to sustain human life . . . comfortably.

Mr. Lovelock offers an existing and proven technology for averting climatic disaster. His theories, knowledge, suggestions should not be ignored or dismissed as quackery: to do so is to gamble with the future of humanity.
