Abstract

This paper reports the results of the Global Warming Sub-Task of the ExternE Project, which has sought to apply and extend the established ExternE methodology for marginal external costs to the climate change damages of greenhouse gas emissions.

Some modifications of the ExternE methodology have been required to allow for the high level of aggregation that is necessary in addressing complex, global, long-term effects. There is no dependence on emission location. We use global emission scenarios defined by the IPCC and calculate greenhouse gas concentration, radiative forcing and consequential changes in global mean temperature, precipitation and sea level rise. Site-specific impact analysis is infeasible. Instead we rely on analyses of impact at a highly aggregated level (national or higher) as an input to climate change damage models.

Existing climate change models FUND and the Open Framework have been used. The models have some common features, both calculating greenhouse gas marginal damages. But FUND's strengths are in dynamic and integrated analysis, whilst the Open Framework concentrates on first order impacts and spatial issues. Comparing results to improve understanding of the issues has therefore been the goal of the exercise, not model convergence.
