The science is clear: climate change is real. In 2015, 195 countries adopted the global climate deal in Paris. Nonetheless, numerous well-organized conservative think tanks (CTTs) deny that climate change is happening. We ask what kind of counterclaims are used by climate-sceptic CTTs and to what extent these counterclaims change over time. We analyse about 2500 blog articles from prominent CTTs in the USA and Germany between 2008 and 2016. Our results show that sceptical arguments about climate policy and science dominate the countermovement. At the same time, we detect that the prevalence of counterclaims is CTT-specific and that US think tanks show a greater variability compared to their German counterparts. In a surprising outcome, we find that the Paris Agreement did not affect the climate denial movement. Based on these insights, we discuss our contributions to social movement research in the climate change denial context and derive conclusions for pro-climate campaigns.

气候变化——这不是真的！美国和德国气候怀疑论智库的比较分析

科学很清楚：气候变化是真实存在的。2015 年，195 个国家在巴黎通过了全球气候协议。尽管如此，许多组织良好的保守派智囊团 (CTT) 否认气候变化正在发生。我们询问对气候持怀疑态度的 CTT 使用什么样的反诉以及这些反诉随时间变化的程度。我们分析了 2008 年至 2016 年间来自美国和德国著名 CTT 的大约 2500 篇博客文章。我们的结果表明，对气候政策和科学的怀疑论点主导了反运动。同时，我们发现反诉的普遍性是 CTT 特有的，与德国智库相比，美国智库表现出更大的可变性。令人惊讶的结果是，我们发现《巴黎协定》并未影响气候否认运动。基于这些见解，
