Abstract
Purpose of Review
This review (1) describes the intersecting literature on climate change adaptation (CCA) and uncertainty (N= 562), and (2) synthesizes the findings of empirical studies about decision-maker uncertainty (n = 97).
Recent Findings
Uncertainty can be a barrier to adaptation, yet it is most often studied in relation to the scientific process, while uncertainties in people’s decision-making and their impact on CCA are less studied.
Summary
Despite the predominance of scientific uncertainties (52%), we see an upward-trend in studies of decision-making uncertainty (24%), and in combining natural and social sciences approaches (24%). Multiple sources of uncertainty influence CCA decisions besides climate trends, and their saliency and people’s responses vary depending on the role/function of the decision-maker and the timeframe of the decision. Concerns involve situational uncertainties, response options, and their consequences. Decision-makers are more likely to incorporate uncertainties in their adaptation decisions than suppress them or delay action, although the response is sensitive to the type of information sought and timeframes.
