Public attitudes towards climate change: A cross-country analysis

Addressing climate change requires international effort from both governments and the public. Climate change concern is a crucial variable influencing public support for measures to address climate change. Combining country-level data with data from the Pew Research Center Spring 2015 Global Attitudes Survey, we test whether perceived threats from climate change influence climate change concern. We distinguish between personal threat and planetary threat and we find that both threats have substantive effects on climate change concern, with personal threat exerting a greater influence on climate change concern than planetary threat. The effects of both types of threats are also moderated by Gross Domestic Product per capita, such that threats have stronger effects on climate change concern in high-income countries than in low-income countries. Our findings contribute to the existing literature and open up new debates concerning the role of threats in climate change concern and have implications for climate change communication.

Automated summary

Both personal threat and planetary threat have substantive effects on climate change concern, with personal threat exerting a greater influence. Climate change concern is higher in high-income countries, indicating the importance of threat communication in addressing climate change.
