I also explain the policy implications of climate change uncertainty. First, the uncertainty … stronger actions to reduce CO2 emissions. Second, uncertainty interacts with two kinds of irreversibilities. First, CO2 remains …

The paper illustrates how one may assess our comprehensive uncertainty about the various relations in the entire chain ….5 °C. The 99 percent confidence interval ranges from 3.0 °C to 6.9 °C. Uncertainty about socio-economic drivers of climate … change lie behind a non-trivial part of this uncertainty about global warming …

Here we study choice of climate policy that minimizes … maximum regret with deep uncertainty regarding both the correct climate model and the appropriate time discount rate to use in … normative uncertainty about the appropriate rate. The findings regarding climate policy are novel and informative. The MMR …

The design and conduct of climate change policy necessarily confronts uncertainty along multiple fronts. We explore the … in the future. We appeal to decision theory under risk, model ambiguity and misspecification concerns to provide an … economically motivated approach to uncertainty quantification. We show how this approach reduces the many facets of uncertainty …
