Environment & Climate Change

Following the COP27 climate conference in Egypt, Robert Stavins said in an interview with the Harvard Gazette that the talks were both frustrating and hopeful: frustrating because they did little to accelerate the slow pace of action to reduce carbon emissions, and hopeful because of a reawakened dialogue between the world’s biggest emitters—the U.S. and China—and movement to address climate-related damage to the world’s most vulnerable nations.

For an assessment of what was done, and left undone, at the recent United Nations’ Conference of the Parties on climate change, the Gazette spoke with Rob Stavins, the Harvard Kennedy School’s A.J. Meyer Professor of Energy and Economic Development and head of the Harvard Project on Climate Agreements, who attended his first COP in 2007 in Bali. 

Kelly Sims Gallagher asserts that politicians' pledges of dramatic long-term reductions should not let them off the hook for their failure to achieve more modest progress in the short term.

Robert Stowe details U.S. President Joe Biden's actions on climate change and discusses the implications for U.S. climate change leadership.

At one point in human history, water’s importance in war went beyond bearing convoys, hiding submarines, and slaking soldiers’ thirst. Water was often itself a weapon. In areas where it was scarce, armies took action to make it scarcer to force besieged enemy cities to capitulate, and in areas where it was abundant, combatants destroyed dams and watched the resulting floods carry their adversaries away. Today, however, most combatants recoil at the use of water as a weapon, and only the most depraved deploy it.

The Biden Administration is showing a renewed commitment to addressing climate change, but there is still a long road ahead for the development of substantive domestic policies to reduce greenhouse-gas emissions. That was one of the messages delivered on Friday (April 30) during a Virtual Forum hosted by the Harvard Project on Climate Agreements.

Since the end of World War II, nation-states in international conflict have made concerted efforts to restrain the weaponization of water. Distinct from realist and rationalist explanations, the historical record reveals the rise of an international normative inhibition—a “water taboo”—on using water as a weapon.

In order to fully appreciate the global climate-change challenge that the Biden administration will face, Robert Stavins reflects on the history of international negotiations that brought us to this point.

Joseph Nye writes that with less preponderance and facing a more complex world, the United States must exercise power with as well as over others and use its soft power to attract their cooperation. To do that, the United States will have to rediscover the importance of the institutions Donald Trump's administration abandoned.

At the annual UN General Assembly, President Xi of China pledged that his nation would peak its carbon emissions before 2030 and hit net zero emissions by 2060, without revealing how the nation plans to reach those goals. Joe Aldy, an economist and Professor of Public Policy at Harvard's Kennedy School, joins Host Steve Curwood to discuss what this step by the world’s largest greenhouse gas emitter means for international climate policy in the context of the failed climate leadership by the Trump Administration.
