The CMIP Panel and WGCM Infrastructure Panel (WIP) continue to discuss and evolve the CMIP delivery timeline in close coordination with the CMIP Task Teams and through regular engagement with the wider community. For the DECK and the subset of CMIP experiments aimed at aligning with the IPCC and other national and international climate assessments, the CMIP7 Assessment Fast Track, there can be no definitive timeline until the IPCC approve the Working Group I timeline (expected at the next IPCC Plenary in July 2025). Community MIPs do not need to align with that timeline, although they may choose to do so. Our working timeline is outlined below, this is being reviewed regularly in consultation with the community.
In September 2023 the Strategic Ensemble Design (SED) Task Team provided a first proposed set of Assessment Fast Track experiments after discussions with the Task Team members, stakeholders and MIPs. Two rounds of consultation followed with the modelling centres and with the wider community. After further discussion within the SED TT, CMIP Panel and with proposing MIPs a final recommendation of the Assessment Fast Track experiment selection (figure below) was made to the WGCM meeting in March 2024, and subsequently endorsed.

Want to learn more about the experiments and why they were selected for the Assessment Fast Track? The figure below summarises all of the experiments chosen for the Assessment Fast Track, along with which MIP proposed them. The interactive experiment viewer underneath the figure also outlines why each experiment was selected.
