| Zusammenfassung |
| Climate models are the measure of choice when observations are scarce or for questions
concerning the future. However, when working with models, not only the internal variability
of the climate system is of importance. The specific variability of the models has
also to be taken into account, especially when they are compared on a quantitative
scale. Till now the focus of multi-model or model ensemble studies has been on
the research question itself, inter-model differences were of minor importance or
completely neglected. Here we present results based on both control runs and transient
simulations with a range of different Earth system models. One finding is that, for
variables such as surface DIC, pH and pCO2, the inter-model spread of a model
ensemble is larger for the inter-annual variability than for the anthropogenic trend. |
