The hole in the ozone layer is now the size of a continent. Ships can negotiate the North West Passage without confronting pack ice. Floods devastate Mozambique and tinder-dry forests of the American North-West go up in a blaze. Yet scientists are still divided as to whether this is a random blip or an irreversible trend. Worse, political and corporate jargon confuses the issues, sometimes with deliberate disinformation. This book charts up-to-the-minute developments, explores the extent that the human race is responsible for the catastrophes and suggests what can be done to prevent them.
