Environment & Climate Change

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.

Significant technological advances in satellite technology and atmospheric measurements have greatly enhanced the understanding of methane concentrations and emissions. The dynamic ways in which those advancements are allowing researchers to monitor methane emissions down to the source level was the focus of discussion Thursday (November 17) at a COP-27 side event co-hosted by the Harvard Project on Climate Agreements, the Enel Foundation, and the government of Mexico.

Paul Joskow, the Elizabeth and James Killian Professor of Economics emeritus at MIT and former President and CEO of the Alfred P. Sloan Foundation in New York City, shared his thoughts on U.S. regulatory economics and climate change policy in the latest episode of “Environmental Insights: Discussions on Policy and Practice from the Harvard Environmental Economics Program.”

Harvard Kennedy School’s Belfer Center for Science and International Affairs today announced the appointment of Lori Garver and Beth Sanner as non-resident Senior Fellows. Garver is a former Deputy Administrator of the National Aeronautics and Space Agency (NASA) and current CEO of Earthrise Alliance. Sanner was Deputy Director of National Intelligence for Mission Integration and is now Professor of Practice at the University of Maryland's Applied Research Lab for Intelligence Security. They will both share their experience and expertise with students and faculty of Harvard Kennedy School and the greater Harvard community.      

Joel Clement writes that because the Biden administration  has moved to repair the damage done by the Trump administration, colleagues from around the global Arctic are optimistic once again about partnering with America on solutions to regional crises .

David Keith argues that either or both carbon removal or solar geoengineering  is needed to cool the planet this century. There are no other options.

Joseph Aldy and Richard Zeckhauser advocate for urgently getting serious about solar geoengineering as a realistic response to climate change that could significantly curb consequences to human well-being.

Joel Clement details the concerns surrounding the use of solar geoengineering to mask the effects of climate change and argues for using existing technology to quickly transition away from fossil fuels.

To mark Earth Day 2021, a number of Belfer Center climate, security, and intelligence experts took part in two conferences that identified and discussed the impacts of climate change not only on the environment and well-being of the world’s people, but also on international security and political stability throughout the world.

This report is derived from a half-day conference in April 2021 co-sponsored by the Intelligence Project and the Environment and Natural Resources Program at Harvard Kennedy School’s Belfer Center for Science and International Affairs, along with the Center for Climate and Security and The Cipher Brief. It explores the requirements of the U.S. Intelligence Community (IC) to fulfill the mission prescribed by President Biden, DNI Haines, and Secretary Kerry. The IC must rise to challenge, unshackled from the past, to re-imagine its role in combatting climate change. The IC has talked the talk about climate change, and now it needs to walk the walk. The stakes are too high not to do so.
