The economics of global warming

Bush keeps arguing that we can't afford to address the global warming problem because programs to reduce greenhouse gases are too costly. Perhaps he should think again:

Global warming could cost the world's economies up to 20 per cent of their gross domestic product (GDP) if urgent action is not taken to stop floods, storms and natural catastrophes.

That stark warning was given to Tony Blair and his cabinet yesterday by Sir Nicholas Stern, a former World Bank economist, and is said to have left cabinet ministers chastened by the magnitude of the threat posed by climate change.

In a preview of a report he is to deliver next Monday, Sir Nicholas told the Cabinet the world would have to pay 1 per cent of its annual GDP to avert catastrophe. But doing nothing could cost 5 to 20 times that amount. He told them: "Business- as-usual will derail growth."

Gosh. Who'd uv thought?
