Joseph Nye considers lessons from his own work on preventing the spread of nuclear technology in the 1970s.

Why do we think Vladimir Putin will not use “the bomb” when there is so much evidence that he will?

In its push for greener energy, Washington is giving biofuels a boost. But just how green are they? Daniel Schrag, Co-Director of the Science, Technology, and Public Policy Program, argued the case for biofuels, opposite Carlisle Ford Runge, who argued against them.

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.”

Carbon capture, utilization, and storage (CCUS) is very likely to be a key technology for achieving the Biden administration's goal of net-zero greenhouse gas emissions by 2050. But absent regulation requiring its use, CCUS needs to become more economical in order for deployment in the United States to expand significantly.

This paper provides an overview on the main impacts of biofuels production on water resources within the United States, with an emphasis on the corn-based ethanol market and the agricultural stage. The following issues are examined:

• the relationship between biofuel production and water availability;
• trends and policy options for future biofuel production and the tradeoffs for water scarcity;
• technological changes in transportation fleet, with consequential effects on biofuels demand and water resources;
• considerations for policy makers who seek to reduce the future impact of biofuels on water sustainability.

To ensure that the world has reliable access to the neutrons it needs, at the lowest possible cost, and to facilitate further efforts to minimize and eventually eliminate civilian use of highly enriched uranium, we need an international mechanism to anticipate worldwide neutron needs and plan how to meet them. In essence, the 2016 National Academies’ report recommendation (which sadly remains unfulfilled even in the United States) should be internationalized.

The success of U.S. President Joe Biden's China policy will depend on whether the two powers can cooperate in producing global public goods, while competing in other areas. The U.S.-China relationship is a "cooperative rivalry," in which the terms of competition will require equal attention to both sides of the oxymoron.  Joseph Nye argues that it will not be easy.

This study provides a whole-systems simulation on how to halve global CO2 emissions by 2050, compared to 2010, with an emphasis on technologies and costs, in order to avoid a dangerous increase in the global mean surface temperature by end the of this century.

A Middle East-wide forum could facilitate dialogue and transparency on a range of short-term measures, engendering momentum to then take on other more complex items, such as regional arms control.
