are addressed in the report of the Effects Panel. The Effects Panel's report is more constrained in scope and presents a succinct representation of data and knowledge to serve as a backdrop for current policy decisions. In doing so, it examines in depth only a few topics that illustrate the extent to which the current science base is sufficient to inform policy decisions. The panel believes the principal difference between its analysis and that of the IPCC is that in the Effects Panel's analysis a greater credence is accorded to the uncertainties in the current scientific knowledge and tools.
The task assigned to the Effects Panel did not require it to assess policy issues as such. Nevertheless, its members record here their support of the conclusions, including the need for prudent response, that are expressed in the report of the Synthesis Panel (Part One).
