The Coupled Model Intercomparison Project (CMIP) identified four fundamental topics on which coupled modelling offers opportunities for rapid progress across the seventh phase of the project, CMIP7: 1) Patterns of sea surface warming, 2) Changing extremes, 3) The Water-Carbon-Climate nexus, and 4) Points of no return/ratcheting. CMIP7 includes Diagnostic, Evaluation, and Characterization of Klima (DECK) and Assessment Fast Track experiments to address these guiding science priorities as well as the community’s requirements for prediction and projection, attribution, characterisation, and process understanding towards assessment of state-of-the-art Earth system models.

We invite contributions across research using coupled Earth system modelling including representation of historical and future change, comparison with previous CMIP phases, idealised analyses, single- or multi-model frameworks, and others across different timescales. We are especially interested in studies examining responses using the CMIP7 Assessment Fast Track. Submissions that explore interactions across multiple components of the Earth system—ocean, atmosphere, cryosphere, land surface and subsurface, and biosphere—and highlight novel insight into the coupled Earth system are highly encouraged.
