Abstract: Climate change has become increasingly politicized, prompting concerns that it may generate new societal rifts. While elite-level rhetoric—particularly among radical right actors—has grown more adversarial, it remains unclear whether similar affective divisions have emerged among citizens. Using cross-national survey data, this paper examines affective polarization over climate change in France, Germany, Greece, Hungary, Italy, and Poland. Mirroring real-world debates that pit stricter climate protection against economic prosperity, we assess mutual affect between individuals on either side of this division, and estimate polarization across the full attitudinal spectrum. Across all countries, we find significant affective polarization with a clear asymmetric pattern: pro-climate citizens express clear in-group warmth and out-group coldness, whereas pro-growth citizens show little affective opposition and in some cases even evaluate climate-oriented individuals more positively than their own group. Moreover, affective polarization among pro-climate respondents is not associated with reduced political tolerance. These findings suggest that mass affective polarization over climate action is less entrenched than elite discourse implies.
