The Intergovernmental Panel on Climate Change (IPCC) publishes periodical reports (assessments) informing policymakers and the public on issues related to global climate change. The IPCC uses verbal descriptions of uncertainty (such as unlikely) to convey the underlying imprecision of its forecasts and conclusions. Previous studies showed that the public interprets these probabilistic statements as less extreme than intended by the authors, and that there are large individual differences in the interpretation of these statements. These studies suggest that supplementing the probability words with numerical ranges would increase differentiation between terms and consistency of interpretation. Climate change is a global issue and the IPCC is a global body whose reports and conclusions are translated to many languages and have international impact. This project is a collaborative multi-national study of the of IPCC communication of uncertainty. We plan to administer translated questionnaires in many countries, to investigate cross-national differences in interpretation of probabilistic pronouncements, relate those to attitudes towards global climate change, and outline methods to improve the effectiveness of communication. Our results and recommendations should help improve the way the IPCC communicate uncertainty in its future reports.

政府间气候变化小组（IPCC）发布了定期报告（评估），向政策制定者和公众提供与全球气候变化有关的问题。 IPCC使用不确定性的口头描述（例如不太可能）传达其预测和结论的潜在不精确。先前的研究表明，公众将这些概率陈述解释为作者预期的极端，并且在这些陈述的解释中存在很大的个体差异。这些研究表明，补充数值范围的概率单词将增加术语和解释一致性之间的区分。 气候变化是一个全球问题，IPCC是一个全球机构，其报告和结论被转化为多种语言并具有国际影响。该项目是对IPCC不确定性交流的协作跨国研究。我们计划在许多国家 /地区管理翻译问卷，以调查概率声明解释中的跨国差异，将这些差异与对全球气候变化的态度有关，并概述提高沟通有效性的方法。我们的结果和建议应有助于改善IPCC在未来报告中传达不确定性的方式。
