LEADERSHIP REQUIRED

John Holdren, President Obama's science adviser, on the need for climate change leadership:

The industrialised nations need to get their acts together before they can expect the developing countries to come on board. We have historically produced a large part of the problem, although the numbers are shifting. Two things are obvious: the industrialised nations have an obligation to lead, and the developing countries have to join pretty soon, or we're going to be cooked.

If, as we are constantly told, reducing carbon emissions presents unparalleled economic opportunities, why aren't developing countries jumping on the bandwagon?
