In a deeply polarized political environment, Americans are more divided on climate change than ever before. Yet three recent developments could advance climate policy, despite partisan politics, according to a new article in the journal Political Science & Politics co-authored by UCLA Luskin Center for Innovation faculty director Megan Mullin and Patrick J. Egan of New York University:

• Partisan cohesion and Democratic initiative. The Republican and Democratic parties have become more unified internally. While Republicans are less concerned about climate change than ever before, growing cohesion among Democrats, both among elected officials and members of the public, has elevated climate change as a party priority and increased their willingness to take electoral risks to address it.
• Clean-energy expansion in Republican states. Even though decision-makers in Republican-led states have backpedaled on support for clean energy, those states are leaders in clean-energy production. Nearly 40% of U.S. renewable energy is situated in the Republican-led states of Iowa, Kansas, Oklahoma and Texas, suggesting that markets can overcome politics in the transition to a clean-energy economy.
• Partisan distribution of climate impacts. Heavily Republican areas may suffer disproportionately from the worst effects of climate change. Mullin and Egan bring together maps of climate risk with county voting records to show that Republican counties have higher percentages of properties at severe or extreme risk from flooding and fire over the next 30 years. This may inspire partisan voters to demand political action by their elected officials.
