A Potential Disintegration of the West Antarctic Ice Sheet: Implications for Economic Analyses of Climate Policy
The Earth system may react in a nonlinear threshold response to climate forcings. Incorporating threshold responses into integrated assessment models (IAMs) used for climate policy analysis poses nontrivial challenges, for example due to methodological limitations and pervasive deep uncertainties.
