Prior research shows that public opinion on climate politics sorts along partisan lines. However, they leave open the question of whether climate politics and other politically salient issues exhibit tendencies for issue alignment, which the political polarization literature identifies as among the most deleterious aspects of polarization. Using a network approach and social media data from the Twitter platform, we study polarization of public opinion toward climate politics and ten other politically salient topics during the 2019 Finnish elections as the emergence of opposing groups in a public forum. We find that while climate politics is not particularly polarized compared to the other topics, it is subject to partisan sorting and issue alignment within the universalist-communitarian dimension of European politics that arose following the growth of right-wing populism. Notably, climate politics is consistently aligned with the immigration issue, and temporal trends indicate that this phenomenon will likely persist.

先前的研究表明，关于气候政治的公众舆论按党派划分。然而，他们留下了一个问题，即气候政治和其他政治上的突出问题是否表现出问题对齐的趋势，政治两极分化文献认为这是两极分化最有害的方面之一。使用来自 Twitter 平台的网络方法和社交媒体数据，我们研究了 2019 年芬兰选举期间公众舆论对气候政治和其他十个政治突出话题的两极分化，因为公共论坛上出现了反对团体。我们发现，虽然与其他主题相比，气候政治并没有特别两极分化，它受制于右翼民粹主义增长后出现的欧洲政治的普遍主义 - 社区主义维度内的党派分类和问题对齐。值得注意的是，气候政治始终与移民问题保持一致，时间趋势表明这种现象可能会持续下去。
