Environment & Climate Change

Al-Juaied and Whitmore examine the costs and prospects for direct air carbon capture and storage (DACCS), and identify types of funding needed for early deployment for DACCS and building momentum for later widespread deployment. The challenges of implementing DACCS at very large scale further emphasize the need for urgent and widespread action to reduce emissions, which should continue to be the main priority for meeting climate goals.

Economic historian Emma Rothschild, the Jeremy and Jane Knowles Professor of History at Harvard, lauded the efforts of young scholars to discover local solutions to mitigate the impacts of global climate change in the latest episode of “Environmental Insights: Discussions on Policy and Practice from the Harvard Environmental Economics Program.” The podcast is produced by the Harvard Environmental Economics Program.

Stephen Walt advises that in order to prepare students of public policy schools for a rapidly changing world, faculty should teach historical cases where the prevailing theories led to bad policy choices, and where new ones had to be devised to address a novel set of circumstances. 

Joseph S. Nye argues that history shows that globalization is largely driven by technological changes that reduce the importance of distance, and that will not change.

While the Paris Agreement provides the framework for the nations of the world to slow the growth of CO2 emissions, additional policy and technological tools will have to be deployed to meet the challenge of climate change. That’s the perspective expressed by Daniel Bodansky, the Regents’ Professor of Law at the Sandra Day O'Connor College of Law at Arizona State University, during the latest episode of “Environmental Insights: Discussions on Policy and Practice from the Harvard Environmental Economics Program,” a podcast produced by the Harvard Environmental Economics Program.

In late 2017, Mexico made headlines as Italian company Enel bid what was then a world-record low price for renewable energy in the country’s third such energy auction. This development was possible due to the historical and sweeping energy reforms passed with broad support in Mexico in 2013. Then-President Enrique Peña Nieto had succeeded where previous Mexican presidents had failed, reversing decades of resource nationalism and overhauling the energy sector through constitutional reforms that gave the private sector a larger role and advantaged renewable energy in Mexico’s economy. The 2017 auction seemed to indicate Mexico’s bright future not only as a conventional oil producer, but also as a clean energy power.

Joseph Nye analyzes why the Cold War metaphor in relation to  the U.S. and China, although convenient, is lazy and potentially dangerous. It obscures and misleads us by underestimating the real challenge we face — and offering ineffective strategies.

Stephen Walt argues that what 9/11 means to future generations depends less on what actually occurred on that day or on how the United States and others responded and more on what the United States and others do from this day forward. 

During the Cold War, US grand strategy focused on containing the power of the Soviet Union. China's rise now requires America and its allies to develop a strategy that seeks not total victory over an existential threat, but rather managed competition that allows for both cooperation and rivalry within a rules-based system.

Stephen Walt asks whether the United States is a good model for other liberal states and whether its policy judgments are ones that others should trust and follow, especially with respect to foreign policy.  He argues that—on balance—the answer to both questions is "no."
