Europe after the Russo-Ukrainian War must develop a new security structure to defend against any Russian aggression. The safest option is a non-offensive, confidence-building defense. This option includes proposals such as the “spider in the web” strategy and the “porcupine” strategy to provide for European security in a region threatened by Russian expansion—without relying on the threat of nuclear war. 

The non-Soviet members of the Warsaw Pact contributed to the end of the Cold War along with the superpowers. These Eastern European states recognized that their relationship with the Soviet Union would impede their success in the post–Cold War world, so they ended the Pact.

Calder Walton recounts how Russia and China are using their intelligence agencies to reverse the outcome of the Cold War

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.

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.

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.

John Holdren spoke to The Harvard Gazette about the proposed Inflation Reduction Act legislation and its potential impact, should it survive House scrutiny and be signed by President Biden.

Rather than revolutionizing war, drones demonstrate its evolution. The principle of air warfare remains avoiding exposure to the enemy. Drones are unlikely to shift the offense-defense balance toward the offense because they are vulnerable to attacks from the ground and air.

On April 11, 2022, The New York Times covered the launch of the new Permafrost Pathways project, a collaboration between the Belfer Center's Arctic Initiative, Woodwell Climate Research Center, and the Alaskan Institute for Justice. The six-year effort by climate scientists and policy experts aims to fill gaps in knowledge about planet-warming emissions and help affected communities in Alaska.

Robert Stavins closely examines the advantages and disadvantages of two distinct pricing instruments for reducing carbon emissions—carbon taxes and cap-and-trade. Both policy instruments are in common use today in many countries although not in the United States. Stavins looks at the practical challenges, financial implications, and political feasibility of both approaches, concluding that while they are equivalent in many ways, they can perform quite differently along other dimensions, making an apples-to-apples comparison quite difficult.
