The authors explore, in particular, the implications for CO2 removal and solar geoengineering of the Paris Agreement's long-term temperature goals, provision for "removals by sinks," and market-based mitigation mechanisms.

John S. Park, Stanton Nuclear Security Junior Faculty Fellow at the Massachusetts Institute of Technology and Project on Managing the Atom Associate, argues that cooperation between North Korea and Iran has been a critical—yet underexamined—enabler of North Korea's recent success. He concludes that the time has come for the United States to view the two previously independent missile programs as two sides of the same coin and recommends strategies for disrupting the procurement channels between Iran and North Korea.

Published along with the report Unleashing the Nuclear Watchdog: Strengthening and Reform of the IAEA — the result of more than two years of research  and examining all aspects of the Agency's mandate and operations — this policy brief summarizes the report's key findings and policy recommendations for strengthening and reforming the IAEA.

"The United States has been a leading light in agricultural biotechnology as a platform technology and continues to serve as an important role model for countries around the seeking to address global food challenges. A key source of this leadership has been its commitment to using a science-led regulatory system for determining the approval of new products. The rest of the world needs this demonstrated leadership now more than ever given rising food prices and related political unrests around the world. Failure on the part of the United States to champion agricultural biotechnology will undermine confidence in the ability of the global community to confront the challenges of food security. Retracting from using science and technology to address emerging challenges will not result in any savings; it will only defer problems and future costs are likely to be higher."

Dramatic growth in nuclear energy would be required for nuclear power to provide a significant part of the carbon-free energy the world is likely to need in the 21st century, or a major part in meeting other energy challenges. This would require increased support from governments, utilities, and publics around the world. Achieving that support is likely to require improved economics and major progress toward resolving issues of nuclear safety, proliferation-resistance, and nuclear waste management. This is likely to require both research, development, and demonstration (RD&D) of improved technologies and new policy approaches.

With regard to developing a new international framework, developed countries should acknowledge how grave the consequences would be to easily give in to a Kyoto extension. Merely extending the Kyoto Protocol would surely delay mitigation actions on the part of developing countries and discourage the U.S. from making serious efforts to reduce its large energy consumption. In other words, no country should end up being a "climate-killer" in its attempts to avoid being called a "Kyoto-killer."

An effective international climate agreement poses formidable challenges. Existing agreements, naturally, have some good features. Further improvements are being discussed in the current negotiations. But the cost and uncertainty associated with regular renegotiation of commitments is not being addressed. The São Paulo Proposal suggests mechanisms that would avoid the need for regular renegotiation of commitments and suggests other ways to make international climate agreements more effective.

Our proposal for a post-2012 international global climate policy agreement contains three essential elements: meaningful involvement by key industrialized and developing nations; an emphasis on an extended time path of targets; and inclusion of market-based policy instruments. This architecture is consistent with fundamental aspects of the science, economics, and politics of global climate change.

The intended impact of e-government is simply better government. However, a majority of e-government initiatives around the world, including many in the Arab states, have been unsuccessful in securing positive outcomes.
