The Need for Multiple Types of Information to Inform Climate Change Assessment

Abstract

Information on ecosystem characteristics as well as economic statistics is needed to more fully inform decision makers on the impacts of climate change on human well-being. Climate change risks involve potentially large and irreversible as well as highly uncertain impacts that need to be evaluated with information that complements cost-benefit analysis. Information on the irreversibility of impacts also is relevant for evaluating implications for intergenerational equity. In addition, climate change is subject to a large degree of Knightian uncertainty, making it useful to understand how individuals perceive and evaluate climate change risks.
