The second Trump administration has aggressively disrupted climate policy and politics, both domestically and internationally. Trump has prioritized domestic oil and coal interests, gutting the Biden administration’s main climate policy and withdrawing permits for major wind and solar projects. In recent weeks, he has withdrawn the United States from several major international climate institutions – and some argue that he has used oil as an explicit motivation for using force in Venezuela.

To discuss what all of this means for the ongoing global effort to combat climate change, I spoke with two experts who have written extensively about energy and climate politics. Jeff D. Colgan is the Richard Holbrooke Professor in the Department of Political Science and the Watson School at Brown University. He is also the founding director of the Climate Solutions Lab. He recently contributed a piece on Venezuela for Good Authority. Federica Genovese is professor of political science and international relations at the University of Oxford and a recent winner of the prestigious Philip Leverhulme Prize.

Our conversation was based in part on a short open access article that Jeff and Federica wrote for International Organization on “Global Climate Politics after the Return of Trump.” We talked about both the domestic and international implications of the Trump administration’s actions for climate change.

How will artificial intelligence reshape global power? And what can past technological revolutions tell us about today’s U.S.-China rivalry? In this episode of Good Authority, I spoke with Jeffrey Ding, assistant professor of political science at George Washington University and a leading scholar at the intersection of technology and international politics.

Ding’s award-winning book, Technology and the Rise of Great Powers, argues that technological leadership depends less on breakthrough inventions and more on a country’s ability to diffuse new technologies widely across its economy and society. Drawing on historical cases from Britain, the United States, Germany, and Japan, he shows how diffusion capacity helps determine which countries translate innovations into lasting geopolitical advantage.

The book has drawn a lot of attention, including from leading AI companies like Microsoft, and from politicians, including former British prime minister Rishi Sunak. Our conversation explores what this diffusion-centered perspective means for the current race over AI, how China and the United States compare in their technological ecosystems, and what historical analogies can – and cannot – reveal about the future of global politics. And we tackle the big questions about the real constraints facing governments attempting to harness emerging technologies for national power.
