My latest article on Climate Change is now availible from: http://climatechangeaction.blogspot.com/2005/11/what-is-future-of-action-on-climate.html This article is focused on possible future frameworks for action on climate change, and possible new measures to achive the greatest result at the lowest cost. With Russian ratification of the Kyoto Protocol during 2005 attention has quickly shifted to what happens next. The Kyoto commitment period ends in 2012 and no clear plan for what follows currently exists. In this article however I am not purely looking a what happens after Kyoto in terms of an international framework, rather I am looking at the spectrum of future international measures which may be used for climate change mitigation. Any descendant of Kyoto is likely to draw from key features of the UNFCCC, but will also have to make significant improvements. The key issues to be addressed are: * the need to bring developing countries into the system * the need to engage with the united states * the need to deal with both historical responsibility and adaption * the need to achieve far greater global emissions reductions.
