Previous research documents that U.S. conservatives, and conservative white males in particular, tend to dismiss the threat of climate change more than others in the U.S. public. Other research indicates that higher education and income can each exacerbate the dismissive tendencies of the political Right. Bridging these lines of research, the present study examines the extent to which higher education and/or income moderate the ideological divide and the "conservative white male effect" on several climate change opinions, and whether these effects are mediated by an individualistic worldview (e.g., valuing individual liberty and limited government). Using nationally representative survey data of U.S. adults from 2008 to 2017 (N = 20,024), we find that across all beliefs, risk perceptions, and policy preferences examined, the ideological divide strengthens with both higher education and higher income. However, educational attainment plays a stronger role than income in polarizing the views of conservative white males. Further analyses support the hypothesis that differences in individualism partially explain the increased political polarization among more educated and higher-income adults, as well as greater dismissiveness among conservative white males relative to other demographic groups. These results highlight key moderators of opinion polarization, as well as ideological differences among conservatives, that are often overlooked in public discourse about climate change. Implications for climate change education and communication across demographic groups are considered.
