There is a lot we know about climate change, but there is also a lot we don't know. Even if we knew how much CO2 will be emitted over the coming decades, we wouldn't know how much temperatures will rise as a result. And even if we could predict the extent of warming that will occur, we can say...

Common integrated assessment models produce the counterintuitive result that higher risk aversion does not lead to stronger near-term abatement. This paper re-examines this result with a DICE model that is fully coupled with a thermohaline circulation model. It also features Epstein-Zin utility...

Uncertainty is ubiquitous in environmental economics: the field studies interactions between socio-economic and biogeochemical systems and neither is fully understood. So our grasp of their interactions is necessarily limited. We argue that this pervasive uncertainty is best modeled as ambiguity...
