Environment & Climate Change

Climate disasters shape the trajectory of internal conflicts in states highly vulnerable to changes in conflict dynamics. Conflict after a climate disaster escalates when the disaster induces shifts in relative power that enable one side to increase its military efforts. But when one actor is weakened by the disaster and the other lacks the capability to exploit that weakness, conflict intensity declines.

While research suggests that democracy offers an answer to the climate crisis, evidence of the effect of regime type on greenhouse gas emissions is mixed and yields inconclusive findings. This article investigates the effect of regime type on carbon dioxide, nitrous oxide, and methane emissions and presents new evidence showing that when it comes to climate change mitigation, democracies are no greener than autocracies.

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.

Steven E. Miller provides an analysis of what the Russian invasion of Ukraine means for the security dynamics of the Arctic and Northern Europe.

Divestment is a prominent strategy championed by activists to induce positive social change. For example, the current fossil fuel divestment movement includes over 1,500 institutions that control $40 trillion in assets. A primary pathway through which divestment is theorized to be effective is by influencing public beliefs and policy preferences, thus pressuring policymakers to take action. However, prior research only tests this argument via qualitative case studies. The authors assess the impact of exposure to information about fossil fuel divestment on public opinion through the use of national survey experiments in three major greenhouse gas emitters: the U.S., India, and South Africa.

Stephen Walt provides A realist POV on the war in Ukraine, competition with China, COVID, and more in the second part of an interview with Foreign Policy Editor-in-Chief Ravi Agrawal.

Stephen M. Walt describes a "gnawing fear that we are living through a series of disruptions that are overwhelming our collective ability to respond." What does this mean for public confidence in the entire political system, and is there any cause for optimism?

Joshua Schwartz and Sabrina Arias write that although Congress seems unable to act, enough states, cities and counties are mobilizing to make a dent in U.S. carbon emissions. The states, cities, counties, and towns that have committed themselves to upholding the Paris agreement currently release a majority of U.S. carbon emissions. If they do manage to meet their targets, they can make a meaningful difference.

Joseph Nye  discusses the following: Why the United States must work with China on global issues such as climate change, pandemics, and other transnational concerns, despite rivalry between the two countries; the "three-dimensional chess game" between the U.S. and China, with military, economic, and ecological boards; the importance of soft power; and differences from the U.S. relationship with the Soviet Union.

Stephen Walt enumerates the challenges the U.S. president should prepare for in 2021.
