Environment & Climate Change

On March 26, the study group met for the first time to examine recent democratic progress and backsliding in African countries. The session focused on ongoing conflicts in different regions of Africa and examined their political underpinnings. Participants also discussed the role of third-party actors in supporting and facilitating conflict mediation and peacebuilding efforts in the continent. The study group counted with the presence of external expert guest Dr. Antje Herrberg, Chief of Staff of the European Union Capacity Building Mission in Niger (EUCAP Sahel Niger). Dr. Herrberg brings more than two decades of professional and personal experience in transition and conflict resolution, intractable conflict, and terrorism with a deep interest to alleviate the suffering of people. Furthermore, Florian Dirmayer, Master in Public Policy Candidate at Harvard Kennedy School, delivered a memo briefing on European Union Security Cooperation with Niger After the 2023 Military Coup.

Plastic pollution in the Arctic marine system is sparsely quantified, and few enforceable policies are in place to ameliorate the issue. In this paper, Dewey and Mackie estimate the flux of plastic through rivers, sea ice, and ocean, and quantify marine plastic pollution from Arctic shipping and fishing. They also examine how a suite of proposed policy interventions would quantitatively change those concentrations.

Direct air capture (DAC) is a type of technology that captures carbon dioxide directly from the air. As the negative impacts of climate change become ever more apparent, governments and private industries have funneled increasing support toward DAC as a critical pathway toward achieving a net-zero future. Although a promising technology, wide-scale deployment of DAC faces several significant challenges.

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.

The climate catastrophe is one of the most pressing and consequential challenges of the 21st century. To meet these challenges and maintain global leadership, the United States needs a diverse, nuanced, and data-driven approach to climate resiliency. U.S. foreign policy should prioritize climate diplomacy with an urgency that is comparable to any other U.S. national security interest.

This paper explores the unique conditions that made the Agreement to Prevent Unregulated High Seas Fisheries in the Central Arctic Ocean possible and examines how success was achieved by the interrelationships of science, policy, legal structures, politics, stakeholder collaboration, and diplomacy.

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?

The explosion of youth climate activism in recent years has focused the world’s attention on the problem like never before, but Michael Greenstone, the Milton Friedman Distinguished Service Professor of Economics at the University of Chicago, argues that young activists often err by trying to turn climate change into a moral issue rather than an environmental one. Greenstone shared his thoughts 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

The rapid pace of Arctic thaw demands collaboration with Russia, no matter the political implications. In a seminar hosted by the Arctic Initiative on May 11, 2022, Andrey Todorov and Andreas Østhagen tackled the thorny question of how to proceed with Arctic Ocean governance in the wake of Russia's invasion of Ukraine and expressed tentative hope for a pragmatic approach to cooperating with Russia on pressing issues such as shipping and fishery management.

For many, integrating “decarbonization” into public policy, corporate and financial strategies has become a requirement, not an option — yet, what happens when the critical link between climate stability and decarbonization breaks?
