Summary
Introduction
The policy-oriented framing of the question about how much anthropogenic climate change the Earth's societies and ecosystems could endure is at least 20 years old. International conferences in Villach (Austria) in 1985 and 1987, and especially the one in Bellagio (Italy) in 1987, involved both scientists and policymakers in contemplating climate change and proposed that long-term environmental targets, such as the rates of global mean temperature increase or sea-level rise, should be used in policymaking (WCP, 1988). Referring to observed historical values, it was recommended to keep the rate of temperature increase below 0.1 °C per decade, based primarily on the estimated rate of ecological adaptation. This seemingly arbitrary proposition is rather specific compared with the riddle implied in the formulation of Article 2 about the ultimate objective of the United Nations Framework Convention on Climate Change (UNFCCC).
Article 2 of the UNFCCC frames the requirement for long-term climate policy in terms of an environmental objective “to prevent dangerous anthropogenic interference with the climate system.” This calls for “inverse approaches” that provide information about possible emission strategies with respect to externally specified environmental targets. Early attempts by Working Group I of the Intergovernmental Panel on Climate Change (IPCC, 1994a) and by Wigley et al. (1996) depict emission paths with respect to given CO2concentration targets.
