| Zusammenfassung |
| Three recently-completed sets of simulations of multiple chemistry-climate
models with greenhouse gases only, with all anthropogenic forcings, and with
anthropogenic and natural forcings, allow the causes of observed
stratospheric changes to be quantitatively assessed using detection and
attribution techniques. The total column ozone response to halogenated ozone
depleting substances and to natural forcings is detectable in
observations, but the total column ozone response to greenhouse gas changes is not separately detectable.
In the middle and upper stratosphere, simulated and observed SBUV/SAGE ozone
changes are broadly consistent, and separate anthropogenic and natural
responses are detectable in observations. The influence of ozone depleting
substances and natural forcings can also be detected separately in observed
lower stratospheric temperature, and the magnitudes of the simulated and
observed responses to these forcings and to greenhouse gas changes are found
to be consistent. In the mid and upper stratosphere the simulated natural and
combined anthropogenic responses are detectable and consistent with
observations, but the influences of greenhouse gases and ozone-depleting
substances could not be separately detected in our analysis. |
