Tim Lambert links to this article by Eric Pooley in Slate's The Big Moneye which points out that, for all the
disagreement among economists regarding the details of

on the following main points (i) the cost of action to stabilise atmospheric concentrations of CO2 and other greenhouse gases will be of the order of 1 per cent of GDP (ii) a strong mitigation
policy is preferable to business as usual
