Abstract Climate science has established human activity as the major cause of climate change. The successive reports of the Intergovernmental Panel on Climate Change (IPCC) have also provided future scenarios of the detrimental effect of rising temperatures. Despite the overwhelming scientific consensus, the voices of climate deniers are still given ample space in the media. Moreover, the urgency of the problem and the importance of taking action are difficult to communicate to the public. This paper analyses the communication strategies employed by climate scientists, climate deniers and climate activists to identify similarities and differences, in particular with regard to expressing (un)certainty. The data are media reports from major British and US newspapers, IPCC reports and the speeches of climate activists, in particular Greta Thunberg. The data are analysed by means of qualitative (eco)critical discourse analysis. The aim is to draw conclusions about how climate change could be communicated more effectively to the general public to promote action.

传达气候变化：如何（不）与人接触并促进行动

摘要 气候科学已将人类活动确定为气候变化的主要原因。政府间气候变化专门委员会 (IPCC) 的连续报告也提供了气温上升有害影响的未来情景。尽管有压倒性的科学共识，但气候否认者的声音仍然在媒体中获得了充足的空间。此外，问题的紧迫性和采取行动的重要性很难向公众传达。本文分析了气候科学家、气候否认者和气候活动家采用的沟通策略，以确定异同，特别是在表达（不）确定性方面。这些数据是来自英国和美国主要报纸的媒体报道、IPCC 报告和气候活动家的演讲，特别是格蕾塔·桑伯格。通过定性（生态）批判性话语分析对数据进行分析。目的是就如何更有效地向公众宣传气候变化以促进行动得出结论。
