Climate stories: why do climate scientists and sceptical voices participate in the climate debate?

This paper explores the polarised debate between climate scientists and sceptical voices. It concludes that focusing on overlapping rationales, such as a sense of duty to publicly engage and recognition that political factors are a key topic of disagreement, as well as encouraging individuals to think critically about their own beliefs, may help to encourage constructive discussion and reduce polarisation. read more »




Endogenous growth, convexity of damages and climate risk: how Nordhaus’ framework supports deep cuts in carbon emissions

‘To slow or not to slow’ (Nordhaus, 1991) was the first economic appraisal of greenhouse gas emissions abatement and founded a large literature on a topic of worldwide importance. We offer our assessment of the original article and trace its legacy, in particular Nordhaus’s later series of ‘DICE’ models. From this work, many have drawn the conclusion that an efficient global emissions abatement policy comprises modest and modestly increasing controls. We use DICE itself to provide an initial illustration that, if the analysis is extended to take more strongly into account three essential elements of the climate problem – the endogeneity of growth, the convexity of damage and climate risk – optimal policy comprises strong controls. read more »
