Abstract
Arising from: Q. Fu et al. Nature 429, 55–58 (2004); see also communication from Tett et al.; Fu et al. reply Satellite observations of tropospheric temperatures seem to show less warming than surface temperatures, contrary to physical predictions1. Fu et al.2 show that statistical correction for the effect of stratospheric cooling brings the satellite-based estimates of tropospheric warming into closer agreement with observations of surface warming. Here we apply the method of Fu et al.2 to output from a state-of-the-art coupled climate model and show that simulated tropospheric temperature trends are consistent with those observed and that their method is robust.
