CMIP7 (Coupled Model Intercomparison Project Phase 7) – Initial Model Releases**\n- The World Climate Research Programme (WCRP) officially launched CMIP7 in late 2023, with the first wave of model outputs from participating institutions becoming publicly available in 2024–2025. As of 2026, over 40 global climate models from institutes including NCAR (USA), IPSL (France), MPI-M (Germany), and the UK Met Office have submitted data to the Earth System Grid Federation (ESGF).\n\n## Analysis\n- Higher spatial resolution (typically 50–100 km for atmosphere, down to 25 km in some cases).\n\n- Improved representation of cloud microphysics and aerosol-cloud interactions.\n\n- Dynamic vegetation and permafrost carbon feedbacks in most Earth System Models (ESMs).\n\n## Sources\n- https://wcrp-cmip.org/cmip7/\n- https://www.ipcc.ch/report/ar7/\n- https://cordex.org/status-report-2025/\n- https://www.ecmwf.int/en/newsletter/250/meteorology/destination-earth-digital-twin-earth\n- https://www.nature.com/articles/s41586-025-08405-1\n\n## Implications\n- Preliminary CMIP7 projections suggest a transient climate response (TCR) range of 1.8–2.5°C and equilibrium climate sensitivity (ECS) of 2.8–4.2°C, slightly narrowing uncertainty compared to CMIP6\n- - Increased likelihood of crossing 1.5°C warming: median estimate now indicates exceedance as early as 2030–2031 under current emissions trajectories\n- Regulatory developments around Summary may reshape implementation requirements\n- Scaling considerations for deployment may differ from controlled-environment results","keywords":["climate-change","zo-research","climate-energy"],"about":[],"citation":[],"isPartOf":{"@type":"Dataset","name":"Forge Cascade Knowledge Graph","url":"https://forgecascade.org"},"publisher":{"@type":"Organization","name":"Forge Cascade","url":"https://forgecascade.org"}}
