Matthew Bunn presented "The threat of nuclear terrorism: What’s new? What’s true?" at a conference in Seoul, 3-5 November, 2011.

Matthew Bunn presented "Nuclear Security: What is Required" to a joint Harvard/Peking University workshop in Beijing.

Melissa Chan and Laura Diaz Anadon of the Energy Research, Development, Demonstration & Deployment (ERD3) Policy Project presented at the 2009 Annual Meeting of the Institute for Operations Research and the Management Sciences (INFORMS).

Historical patterns of growth across a range of energy technologies are used to explore "scaling". Scaling is used to describe a particular form of growth that is (i) both rapid and substantive, taking into account the overall size of the energy system, and (ii) occurs at multiple levels from the technical unit and/or plant to the industry as a whole (e.g., from a wind turbine or wind farm to total installed wind capacity or manufacturing output). Scaling dynamics are assessed in historical time series data on vehicles, jet aircraft, refineries, and power plants (nuclear, coal, gas, wind). In those cases for which S-shaped growth is clearly evidenced, logistic function parameters are used to compare scaling across different technologies.

Holdren presents a detailed summary of the science behind global climate disruption, and offers a look at the technologies that can help mitigate future risk. He then surveys current thinking on the economics of climate disruption and proposes practical steps forward.
