2019年8月，政府间气候变化专门委员会（IPCC）发布了《气候变化与土地特别报告》（SRCCL），在主流和社交媒体上引发了广泛的社会辩论和兴趣。使用计算和概念文本分析，我们检查了Twitter上的6,000多个英语帖子，以确定不同主题的相对存在。然后，我们评估了它们的毒性水平和情绪极性，作为争论和争议的指标。我们发现，首先，肉类消费和饮食选择成为Twitter上讨论最多的问题之一，以回应IPCC的报告，即使它是报告的一个相对次要的元素;第二，这个新的争议问题（肉类和饮食）与之前IPCC报告中强烈争议的问题（对气候科学和IPCC可信度的怀疑）具有相似的高毒性。我们认为，这在一定程度上反映了公众讨论的其他领域中关于肉类和饮食的日益两极分化的叙述，以及从批评气候科学转向批评气候解决方案的运动。最后，我们讨论了这些研究结果对IPCC工作的可能影响，以预测对其报告的反应，并有效地应对这些反应。在线版本包含补充材料，可通过10.1007/s10584-021-03182-1获得。
In August 2019, the Intergovernmental Panel on Climate Change (IPCC) published its Special Report on Climate Change and Land (SRCCL), which generated extensive societal debate and interest in mainstream and social media. Using computational and conceptual text analysis, we examined more than 6,000 English-language posts on Twitter to establish the relative presence of different topics. Then, we assessed their levels of toxicity and sentiment polarity as an indication of contention and controversy. We find first that meat consumption and dietary options became one of the most discussed issues on Twitter in response to the IPCC report, even though it was a relatively minor element of the report; second, this new issue of controversy (meat and diet) had similar, high levels of toxicity to strongly contentious issues in previous IPCC reports (skepticism about climate science and the credibility of the IPCC). We suggest that this is in part a reflection of increasingly polarized narratives about meat and diet found in other areas of public discussion and of a movement away from criticism of climate science towards criticism of climate solutions. Finally, we discuss the possible implications of these findings for the work of the IPCC in anticipating responses to its reports and responding to them effectively. The online version contains supplementary material available at 10.1007/s10584-021-03182-1.
