The Coupled Model Intercomparison Project phase 7 (CMIP7) identified four topics on which coupled modeling offers opportunities for rapid progress: 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 both these guiding science priorities and requirements of prediction and projection, attribution, characterization, and process understanding towards assessment of state-of-the-art Earth system models. We invite contributions across research using coupled Earth system modeling including representation of historical and future change, idealized analyses, single- or multi-model frameworks, and others. 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.
