Climate change can reasonably be expected to increase the frequency and intensity of a variety of potentially disruptive environmental events-slowly at first, but then more quickly. It is prudent to expect to be surprised by the way in which these events may cascade, or have far-reaching effects. During the coming decade, certain climate-related events will produce consequences that exceed the capacity of the affected societies or global systems to manage; these may have global security implications. Although focused on events outside the United States, Climate and Social Stress: Implications for Security Analysis recommends a range of research and policy actions to create a whole-of-government approach to increasing understanding of complex and contingent connections between climate and security, and to inform choices about adapting to and reducing vulnerability to climate change.

This report offers a summary of the substantive presentations during an international workshop, Trends in Science and Technology Relevant to the Biological and Toxin Weapons Convention, held October 31 - November 3, 2010 at the Institute of Biophysics of the Chinese Academy of Sciences. It is meant to provide scientists and other technical experts with factual information about the range and variety of topics discussed at the workshop, which may be of interest to national governments and non-governmental organizations as they begin to prepare for the 7th Review Conference of the Biological and Toxin Weapons Convention (BWC) in 2011. The Beijing workshop reflected the continuing engagement by national academies international scientific organizations, and individual scientists and engineers in considering the biosecurity implications of developments in the life sciences and assessing trends in science and technology (S&T) relevant to nonproliferation. The workshop provided an opportunity for the scientific community to discuss the implications of relevant developments in S&T for multiple aspects of the BWC. Trends in Science and Technology Relevant to the Biological and Toxin Weapons Convention follows the structure of the plenary sessions at the workshop. It begins with introductory material about the BWC and current examples of the types and modes of science advice available to the BWC and other international nonproliferation and disarmament agreements, in particular the Chemical Weapons Convention (CWC). This report includes only a very brief description of the some of the post-presentation discussions held during the plenary sessions - and does not include an account of the small breakout groups - since these were intended to inform the committee's finding and conclusions and will be reflected in the final report.

The 2nd International Forum on Biosecurity, held in Budapest, Hungary on March 30 - April 2, 2008, represents the efforts of a number of individuals and organizations, over the last five years, to engage the international community of life scientists in addressing how to reduce the risk that the results of their work could be used for hostile purposes by terrorists and states. The participants who gathered in Budapest were already engaged in this challenging task, and, therefore, the focus of the meeting was on what had been accomplished and what challenges remained. There was no attempt to achieve consensus, since there exist real and important differences among those involved concerning the appropriate policies and actions to be undertaken. But there was a serious effort to identify a range of potential next steps, and also an effort to identify opportunities where international scientific organizations could make substantive contributions and offer their advice and expertise to policy discussions. The Forum's presentations, discussions, and results are summarized in this book.
