Environment & Climate Change

For most of this century, the Arctic has been a place of peaceful cooperation in science and environmental protection, an approach built on a foundation of multiple agreements reached in the twentieth century. The Russian invasion of Ukraine and the geopolitical reverberations of the war have disrupted or outright halted most collaboration between Western and Russian scientists and conservationists.

Harvard Kennedy School hosted Sarah Ladislaw, Special Assistant to the President and Senior Director for Climate and Energy of the U.S. National Security Council, for an Energy Policy Seminar on the U.S. approach to energy and climate issues in its foreign policy.

This article explores some of the environmental consequences of Russia’s war in Ukraine that are being felt far beyond the battlefields. In the high latitudes of the Arctic, thirty years of collaboration between Russia and the West in the fields of biological research and monitoring – as well as environmental protection – contributed to understanding and conserving transboundary species and ecosystems. For the last two years, however, most international science programs have excluded Russian participation, hampering global efforts to track climate change and protect biodiversity.

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.

As a Predoctoral Research Fellow at the Belfer Center’s Environment and Natural Resources Program and Science, Technology, and Public Policy Program, Lydia Zemke has spent the last two years studying climate finance in developing countries. As she rounds out her time at the Belfer Center, Zemke she reflects on her research interests, her experience conducting fieldwork in Kenya and Costa Rica, and her advice for other early-career researchers. 

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.

Legal scholar Andrey Todorov, Postdoctoral Research Fellow with the Arctic Initiative, reflects on the recent agreement reached by United Nations delegates to protect biodiversity in international waters and its implications for the Arctic. 

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.

Arctic Initiative Research Fellow Andrey Todorov analyzes options to integrate the ecosystem-based approach (EBA) with Arctic Ocean governance.
