Environment & Climate Change

Ashlie Burkart, MD, spoke to a Harvard Kennedy School audience about the potential of regenerative agriculture policies for generating socioeconomic, climate, environmental, health, and welfare benefits.

Harvard Kennedy School’s Energy Policy Seminar series hosted Frances Moore, Associate Professor and the Hurlstone Presidential Chair in the Department of Environmental Science and Policy at the University of California Davis, to present her recent research on how the social cost of carbon is likely significantly underestimated in the academic literature.

At the foot of the Eqi Glacier in Greenland in June, I watched ice formed thousands of years ago drop into the warming ocean. With this vivid depiction of climate change in my mind, I was disappointed that neither of the conferences held last month to prepare for the UN’s upcoming COP28 summit had produced any real breakthroughs.

However, while the need for climate action is rising, the stakes for COP, perhaps counter-intuitively, look to be diminishing. An underwhelming COP28 would be a missed opportunity but it may not be a tragedy. Twenty or even 10 years ago, it was reasonable to hope a co-operative approach could address climate. But it is no longer a realistic expectation — nor the most promising route for progress.

Unlike industrial and other forms of pollution, the long-standing, pervasive problem of municipal solid waste in Arctic cities receives comparatively little attention. As rapid warming in the region compromises existing waste disposal methods such as landfills, Arctic cities will need to develop comprehensive solid waste management strategies for the health of residents and the environment.

The geopolitical implications of solar displacing oil as the world’s major source of energy are enormous. Why has the Middle East been a central arena in the “great game” for the past century? Because countries there have been the major suppliers of the oil and gas that powered 20th-century economies. If, over the next decade, photovoltaic cells that capture energy from the sun were to replace a substantial part of the demand for oil and gas, who will the biggest losers be? And even more consequentially: who will be the biggest winner?

The Harvard Initiative to Reduce Global Methane Emissions released its first publication in May 2023: a research brief titled “Updating Estimates of Methane Emissions: The Case of China.” The Initiative is one of five interdisciplinary research clusters funded by the Salata Institute for Climate and Sustainability at Harvard University. The Harvard Project on Climate Agreements collaborates in the implementation of the Initiative.

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.

ColdHubs, an innovative Nigerian agricultural enterprise that uses solar-powered refrigerated storage units to keep food from spoiling, is slowly but surely expanding to nearby West African countries. But it faces big challenges to scale up and finance its operations, company founder and CEO Nnaemeka Ikegwuonu told a Harvard Kennedy School audience celebrating the 2022 Roy Award winner.

Pakistan’s floods of 2022 were the latest, and most damaging yet, addition to the long history of floods in the country. As the muddy waters slowly recede, the need for speeding up action to face future floods stands clear.

The authors explore an essential element in the portfolio of climate solutions required to rapidly achieve net zero emissions — flue gas carbon capture and storage, whereby carbon can be sifted from emission streams before it enters the atmosphere and safely sequestered in geologic storage systems.
