Global warming is considered one of the most far-reaching environmental problems facing human kind. Thus, understanding international concern for global warming might be the key in creating mitigation and adaptation policies. In this research we aim to assess public concern for global warming at the international level based on a large sample representing 47 nations. To the best of our knowledge, this research is the first to use catastrophe theory to study the influence of factors such as GDP, CO₂ emissions, environmental problems and demographic factors on global warming concern. Stochastic cusp models’ results support the affluence and post-materialism hypotheses advocated by Inglehart. However, our findings contradict the objective environmental problems hypothesis postulated by the same environmental scholar. Results also reveal the existence of a global warming environmental Kuznets curve (EKC). Finally, our findings show that global warming is driven by demographic factors such as age, religiosity and educational level. The findings of this research highlight the importance of applying nonlinear dynamic techniques in investigating concern for global warming at the international level.

突变理论预测国际关注全球变暖

全球变暖被认为是人类面临的最深远的环境问题之一。因此，了解国际社会对全球变暖的关注可能是制定缓解和适应政策的关键。在这项研究中，我们旨在根据代表47个国家的大量样本，评估国际社会对全球变暖的关注。据我们所知，这项研究是首次使用巨灾理论来研究GDP，CO ₂等因素的影响排放，环境问题和人口因素对全球变暖的关注。随机的风口浪尖模型的结果支持了英格哈特倡导的富裕和后物质主义假说。但是，我们的发现与同一位环境学者所提出的客观环境问题假设相矛盾。结果还揭示了全球变暖环境库兹涅茨曲线（EKC）的存在。最后，我们的研究结果表明，全球变暖是由人口因素（例如年龄，宗教信仰和受教育程度）驱动的。这项研究的结果突显了在研究国际层面对全球变暖的关注时应用非线性动力学技术的重要性。
