温暖化リスクコミュニケーション

抄録

　 From the standpoint of an expert of climate change projections, I propose a framework of “Climate change risk communication,” in which various stakeholders, including citizens, experts, industries and governments, communicate with each other on climate change risks. For communication to support adaptation policy making, specific risk information for a particular region and a sector is required; Stakeholders’ proper understanding of uncertainties in natural climate variability and scientific projections is critical. For communication to support developing public opinions for mitigation policies and motivations for individual actions, comprehensive risk information for as various sectors and aspects as we can know at the global scale is required; I believe it important that experts provide unbiased information from a value-neutral standpoint, overcoming exaggerations seen in mass media as well as skepticisms. Overall, I regard it as important to distinguish supporting decision making from decision making itself and to develop mutual trust among stakeholders through the communication.
