Uncertainty in climate change modeling : can global sensitivity analysis be of help? / B. Anderson, E. Borgonovo, M. Galeotti, R. Roson. - In: RISK ANALYSIS. - ISSN 0272-4332. - 34:2(2014 Feb), pp. 271-293. [10.1111/risa.12117]
Abstract:
Integrated assessment models offer a crucial support to decisionmakers in climate policy
making. For a full understanding and corroboration of model results, analysts ought to identify the exogenous variables that influence the model results the most (key drivers), appraise the relevance of interactions, and the direction of change associated with the simultaneous
variation of uncertain variables. We show that such information can be directly extracted
from the data set produced by Monte Carlo simulations. Our discussion is guided by the application to the well-known DICE model of William Nordhaus. The proposed methodology allows analysts to draw robust insights into the dependence of future atmospheric temperature,
global emissions, and carbon costs and taxes on the model’s exogenous variables
