The scientific consensus on climate change is well-established, yet public opinion varies, influenced by online narratives that often contradict scientific findings. Thus, we set out to investigate Croatian citizens' attitudes toward climate change, focusing on the perceived importance of nature and the environment, concerns about climate change, feelings of personal responsibility to mitigate climate change, and beliefs regarding its causes. We initially compared Croatia's climate change attitudes to those in other countries participating in the tenth wave (2020-2022) of the European Social Survey (ESS), revealing Croatia as one of the nations most concerned about climate change and ranking in the top third regarding the importance of environment and nature. However, regarding feelings of personal responsibility to combat climate change, Croatian citizens nearly enter the lowest third of the investigated countries. Furthermore, we focused specifically on the Croatian sample of 1,592 residents (aged 16 to 89; 55% women) by examining regional differences in climate change attitudes across four distinct areas: Mediterranean Croatia, Pannonian Croatia, Northern Croatia, and the capital, Zagreb. These regions vary in historical, cultural, economic, and climatic aspects. Whilst controlling for age, sex, education level, and type of residence, we found significant regional variations. Citizens of the Mediterranean region placed higher importance on nature and the environment compared to citizens of other regions, although marginally compared to Pannonian residents. Yet, citizens of Northern Croatia showed marginally greater concern about climate change than those in the Mediterranean region. No significant differences were found in attributing climate change to natural versus human activities across the regions. Finally, individuals from Northern Croatia reported the lowest levels of personal responsibility for addressing climate change. These findings reveal Croatia's varied climate attitudes within regional contexts, which might prove relevant for crafting targeted public engagement and mitigation strategies.
