George Monbiot discusses his book Heat: How to Stop the Planet from Burning. It now seems certain that we need a 90% cut in our emissions within 25 years if we are to stop ourselves reaching the point where the "climate feedback" becomes unstoppable, and our world becomes largely uninhabitable. Monbiot explains how this cut could be achieved. Combining his knowledge of political campaigning and environmental science, he analyses the possibilities and pitfalls of energy efficiency, nuclear power, renewable resources and new technologies, and applies them to our everyday lives, measuring the cuts that can be made.

Monbiot is a bestselling author and a weekly columnist for the Guardian. In 1995 Nelson Mandela presented him with a United Nations Global 500 Award for outstanding environmental achievement. He has been named by the Evening Standard as one of the 25 most influential people in Britain, and by the Independent on Sunday as one of the 40 international prophets of the 21st Century. His books include Captive State: the Corporate Takeover of Britain and, most recently, The Age of Consent: A Manifesto for a New World Order.
