The fourth and final Nuclear Security Summit took place in Washington DC from March 31-April 01, 2016.  Despite the initial apprehension about the summits in certain parts of the world, it has been a useful process.  With more than 50 countries represented from across the world, the summits elevated the level of awareness of nuclear security. Leaders of established nuclear states began to think about nuclear security in a new way, reducing complacency about the risks of terrorism and sabotage.  This thinking took shape in national and multilateral commitments in areas including nuclear security regulation, physical protection of nuclear materials, nuclear forensics, protection against nuclear smuggling, and insider threats and nuclear terrorism.

The Kyoto Protocol establishes a very complex and ambitious regime, in architecture if not stringency. The problem is that relatively few states, representing only about a quarter of the world's emissions, have been willing to assume emission targets under Kyoto....The future of the Protocol thus seems doubtful at best. Even in the most optimistic scenario, a new round of emissions targets couldn't be agreed in time to prevent a legal gap between the first and second commitment periods. A possible middle ground would be to establish a transitional regime that would be political in nature, but that could evolve over time into a legally-binding regime.

Managing the dangers of global climate change will require developing countries to participate in a global climate regime. So far, however, those nations have been nearly universal in their refusal to make commitments to reduce growth in their greenhouse gas emissions. This paper describes how a set of international "Climate Accession Deals" could encourage large policy shifts that are in developing countries' interests and also reduce greenhouse gas emissions.
