Global interest in tackling climate change has intensified. Awareness that the commitments to reduce emissions of greenhouse gases set out in the Kyoto Protocol to the United Nations Framework Convention on Climate Change expire in 2012, and given general acceptance that the Kyoto Protocol has not been a success, new global approaches to climate change are being considered.
Global warming is a complicated subject. The science is complex and the economics challenging. It is not common in either discipline to try to specify with certainty what will happen over 10-20 year periods, let alone to look ahead 100 or 200 years. While much attention has been focused on the science and economics, not enough has been devoted to what can practicably be achieved in intergovernmental arrangements to handle climate change. This report illustrates one such approach.
