Polarization of Climate Change Beliefs: The Role of the Millennial Generation Identity

Objective This article explores how the Millennial Generation identity-the shared values and experiences of young adults (born between 1980 and 1997)-affects political polarization of climate change belief, specifically how it mediates the relationship between party affiliation and educational attainment. Method To test this, an interaction between Millennial*Republican*education is estimated, using data from an original national survey administered in 2015. Results Millennials are more likely to believe in the evidence of climate change and its anthropogenic causes than older adults of their same party affiliation. Unlike older adults, the most educated Millennials are not the most likely to adhere to political party stance; rather, it is among the least educated Millennials that party sorting is most evident. Conclusion The Millennial Generation identity is meaningful for understanding political attitudes. Important distinctions exist between Millennials and older adults in the evaluation of climate change opinion and related policies.
