Science and the climate change regime

Given rapidly increasing losses from extreme climate events, the world community already has a common interest in action to mitigate and adapt to climate change. However, this common interest is not well served through continued promotion of either mandatory (legally-binding) policies or 'do nothing' policies by various participants in the regime established by the U.N. Framework Convention on Climate Change. The common interest would be better served by a third way, comprised of voluntary 'no regrets' policies that are commensurate with the limited political power of the regime and already have succeeded on small scales in reducing vulnerabilities to extreme climate events and in reducing greenhouse gas emissions. Both mandatory and 'do nothing' policies, as well as the regime itself, have depended upon scientists for political support in the past. But scientists might better serve the common interest of the world community through support of a third way in the future.
