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.

China recently launched the world’s largest emissions trading market, but it is just one component of the nation’s ambitious efforts to curb the rise in greenhouse-gas emissions. That was the message delivered on Thursday (July 22) by Carnegie Mellon University Associate Professor Valerie Karplus during a Virtual Forum hosted by the Harvard Project on Climate Agreements (HPCA) and moderated by Robert Stavins, HPCA Director and A.J. Meyer Professor of Energy and Economic Development.

In order to fully appreciate the global climate-change challenge that the Biden administration will face, Robert Stavins reflects on the history of international negotiations that brought us to this point.

This paper considers the treatment of co-benefits in benefit-cost analysis of federal air quality regulations. Using a comprehensive data set on all major Clean Air Act rules issued by the Environmental Protection Agency over the period 1997–2019, the authors show that (1) co-benefits make up a significant share of the monetized benefits; (2) among the categories of co-benefits, those associated with reductions in fine particulate matter are the most significant; and (3) co-benefits have been pivotal to the quantified net benefit calculation in nearly half of cases.

Ambassador Nicholas Burns speaks about the "devastating portrait" of President Trump's leadership during the COVID-19 pandemic. 

Nobel Prize–winning economist Joseph Stiglitz, University Professor at Columbia University, shared his thoughts on carbon pricing, the post-pandemic economic recovery, and green economy transition during a virtual forum on September 8 sponsored by the Harvard Project on Climate Agreements, and hosted by Robert Stavins, A.J. Meyer Professor of Energy and Economic Development at Harvard Kennedy School.

This essay makes three arguments. First, the US government will need to establish a coronavirus commission, similar to the 9/11 commission, to determine why, since April 2020, the United States has suffered more coronavirus fatalities than any other country in the world. Second, the COVID-19 pandemic represents a watershed for what will be a major national security theme this century: biological threats, both from naturally occurring pathogens and from synthesized biology. Third, intelligence about globalized challenges, such as pandemics, needs to be dramatically reconceptualized, stripping away outmoded levels of secrecy.

Joseph Nye writes that the world is increasingly obsessed with the ongoing power struggle between the United States and China. But the technology-driven shift of power away from states to transnational actors and global forces brings a new and unfamiliar complexity to global affairs.
