The point of the story of the boy who cried wolf is that, finally, a wolf did appear. I feel the same way about the intellectual heirs of Thomas Malthus. Malthusians have finally found a wolf called climate change. Many now agree. But it is far away and coming slowly. "If the worst comes to the worst," mutter the rich to themselves, "we can always let our children cope."
This is the complacency that the latest Human Development Report from the United Nations Development Programme attacks. It does a good job, too. But does it do a good enough job to turn the Bali climate change conference into a call for effective action? I fear not. This is not because it fails to make a morally sound case. It is rather because humanity will change its behaviour only when convinced that the lifestyle the better off enjoy now - and the rest of the world aspires to - remains in reach.
