Comment on “Constraining climate forecasts: The role of prior assumptions”

License . Climate of the Past Reply to Henriksson et al . ’ s comment on “ Using multiple observationally - based constraints to estimate climate sensitivity ” by Annan and Hargreaves ( 2010 )

Henriksson et al. (2010), hereafter HALTL10, criticize Annan and Hargreaves (2006a) (AH06) primarily on the grounds that we assumed that different sources of data were conditionally independent given the climate sensitivity. While we consider this approximation to have been a reasonable one under the circumstances (and provided arguments to justify this approach), we also acknowledged its impor...

Can the Last Glacial Maximum constrain climate sensitivity?

[1] We investigate the relationship between the Last Glacial Maximum (LGM) and climate sensitivity across the PMIP2 multi-model ensemble of GCMs, and find a correlation between tropical temperature and climate sensitivity which is statistically significant and physically plausible. We use this relationship, together with the LGM temperature reconstruction of Annan and Hargreaves (2012), to gene...
