"...[A]ttention is turning to solar geoengineering, also known as solar radiation management. Although the concept of injecting sulfur dioxide into the stratosphere has so far been tested only using computer simulations, there's high confidence that it would work to cool the Earth because it would mimic the well-understood cooling effect of large volcanic eruptions."

China’s approach to strengthening the security of its nuclear weapons, materials, and facilities plays an important role in facilitating strong global action on nuclear security. This report provides a better understanding of Chinese perceptions of the threat of nuclear terrorism and attitudes toward the nuclear security challenge; describes the current status of nuclear security practices in China and of planned improvements in rules and organization, management, and technologies; and recommends steps for further improvements.

The Spring 2011 issue of the Belfer Center newsletter features recent and upcoming activities, research, and analysis by members of the Center community on critical global issues. This issue highlights the Belfer Center’s continuing efforts to build bridges between the United States and Russia to prevent nuclear catastrophe – an effort that began in the 1950s. This issue also features three new books by Center faculty that sharpen global debate on critical issues: God’s Century, by Monica Duffy Toft, The New Harvest by Calestous Juma, and The Future of Power, by Joseph S. Nye.

The Winter 2010/11 issue of the Belfer Center newsletter features recent and upcoming activities, research, and analysis by members of the Center community on critical global issues. This issue highlights a major Belfer Center conference on technology and governance, the Center's involvement in the nuclear threat documentary Countdown to Zero, and a celebration of Belfer Center founder Paul Doty.

Associate Professor of Public Policy and Project on Managing the Atom Co-Principal Investigator Matthew Bunn provides a comprehensive assessment of global efforts to secure and consolidate nuclear stockpiles, and a detailed action plan for securing all nuclear materials in four years.  Securing the Bomb 2010 was commissioned by the Nuclear Threat Initiative (NTI). The full report, with additional information on the threat of nuclear terrorism, is available for download on the NTI website.

Matthew Bunn and Martin B. Malin examine the conditions needed for nuclear energy to grow on a scale large enough for it to be a significant part of the world’s response to climate change. They consider the safety, security, nonproliferation, and waste management risks associated with such growth and recommend approaches to managing these risks. Bunn and Malin argue that although technological solutions may contribute to nuclear expansion in the coming decades, in the near term, creating the conditions for large-scale nuclear energy growth will require major international institutional innovation.

The Belfer Center hosted former Vice President and Nobel Laureate Al Gore and 30 of the United States' top energy and climate experts in October for a "Solutions Summit" on the climate challenge ... participants brainstormed concrete solutions to producing carbon-free electricity, using as a starting point Gore’s July 2008 Generational Challenge to Repower America, which calls on the nation to produce 100 percent of America's electricity from renewable energy and truly clean carbon-free sources within ten years.
