The purpose of the workshop was; to provide a broad base of input to the writing of the draft chapters for IPCC's Second Assessment Report, and to provide an opportunity for policy advisors in several regions of the world to gain a better understanding of the scope and nature of Working Group Ill's assignment. Working Group Ill has been charged with addressing the so-called cross-cutting issues related to greenhouse gases and climate change. This means primarily those issues of a regional or global social and economic nature, and evaluation of policy options. Many of these aspects of climate science, especially in the social and economic sciences, are new departures for IPCC.
