The data include the CH-blend reconstruction and 2.5% and 97.5% uncertainty ranges. The uncertainty ranges reflect both uncertainty in the amplitude of the reconstruction, and sampling uncertainty combined. Forcing inputs also included in file hegerl2006forcing.txt Supplementary Table 1 archived here, and its heading, were replaced on 5 February 2007. This is a corrected version of the previous Table S1, in which only the scaling uncertainty was included; in the corrected Table S1, scaling and sampling uncertainties are also included. ABSTRACT SUPPLIED BY ORIGINATOR: The magnitude and impact of future global warming depends on the sensitivity of the climate system to changes in greenhouse gas concentrations. The commonly accepted range for the equilibrium global mean temperature change in response to a doubling of the atmospheric carbon dioxide concentration, termed climate sensitivity, is 1.5-4.5 K. A number of observational studies, however, find a substantial probability of significantly higher sensitivities, yielding upper limits on climate sensitivity of 7.7 K to above 9 K. Here we demonstrate that such observational estimates of climate sensitivity can be tightened if reconstructions of Northern Hemisphere temperature over the past several centuries are considered. We use large-ensemble energy balance modelling and simulate the temperature response to past solar, volcanic and greenhouse gas forcing to determine which climate sensitivities yield simulations that are in agreement with proxy reconstructions. After accounting for the uncertainty in reconstructions and estimates of past external forcing, we find an independent estimate of climate sensitivity that is very similar to those from instrumental data. If the latter are combined with the result from all proxy reconstructions, then the 5-95 per cent range shrinks to 1.5-6.2 K, thus substantially reducing the probability of very high climate sensitivity.
