The time‐dependence of climate sensitivity
Abstract
A doubled CO 2 coupled ocean‐atmosphere experiment has been run for over 800 years. The ‘effective’ equilibrium climate sensitivity to a doubling of CO 2 (the equilibrium response of the model assuming the feedbacks remained constant at the value found at any given point of the transient response) is calculated throughout the run and found to increase by around 40%. The time‐dependence is associated with differences in cloud feedback arising from inter‐hemispheric temperature differences due to the slower warming rate of the Southern Ocean. The time‐dependence of the climate response has implications for the use of simpler models in scaling GCM results to different scenarios of forcing.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
