| Zusammenfassung |
| In a recent paper Hu et al. (2011) suggest that the recovery of
stratospheric ozone during the first half of this century will significantly
enhance free tropospheric and surface warming caused by the anthropogenic
increase of greenhouse gases, with the effects being most pronounced in
Northern Hemisphere middle and high latitudes. These surprising results are
based on a multi-model analysis of CMIP3 model simulations with and without
prescribed stratospheric ozone recovery. Hu et al. suggest that in order to
properly quantify the tropospheric and surface temperature response to
stratospheric ozone recovery, it is necessary to run coupled
atmosphere-ocean climate models with stratospheric ozone chemistry. The
results of such an experiment are presented here, using a state-of-the-art
chemistry-climate model coupled to a three-dimensional ocean model. In
contrast to Hu et al., we find a much smaller Northern Hemisphere
tropospheric temperature response to ozone recovery, which is of opposite
sign. We suggest that their result is an artifact of the incomplete removal
of the large effect of greenhouse gas warming between the two different sets
of models. |
