Résumé fourni par la source

Archival release of scenariomip-paper-plots, the code used to produce the FaIR v2.2 climate simulations and figures.DATA ARE INDICATIVE AND FOR ILLUSTRATIVE PURPOSES ONLY. Please use the final projections of the ScenarioMIP pathways for CMIP7 in your research here: https://scenariomip.apps.ece.iiasa.ac.at What this release contains A reproducible pipeline that runs FaIR v2.2 over 1750–2501 across the seven ScenarioMIP-CMIP7 emissions pathways (VL, LN, L, ML, M, H, HL), spanning very low to very high / high-legacy emissions futures. A single-source plotting module (scripts/plotting.py) used by both a headless CLI (scripts/make_plots.py) and an interactive Jupyter notebook (notebooks/0505_extensions_plotting.ipynb) to regenerate every figure in the paper. Input emissions/forcing data version-controlled in data/; AR6 FaIR calibration parameters fetched from Zenodo at runtime; cached ensemble output written to data/fair-outputs/fair_run.nc. Scientific context ScenarioMIP-CMIP7 defines a set of emissions-driven scenarios spanning high-end, current-policy, and Paris-aligned futures, including pathways that peak and decline in greenhouse gas concentrations during the 21st century. The simulations archived here illustrate the climate response of these scenarios in a reduced-complexity model (FaIR v2.2 with the AR6 calibrated ensemble) and underpin the figures in the companion GMD paper. Reproducing the figures git clone https://github.com/benmsanderson/scenariomip-paper-plots cd scenariomip-paper-plots python3 -m venv .venv && source .venv/bin/activate pip install -r requirements.txt python scripts/make_plots.py # writes all figures to plots/ Requires Python 3.10+. See the README for the notebook workflow and a memory-limited 5-member test ensemble. Citation If you use this code, please cite both the paper and this Zenodo archive. Paper: Van Vuuren, D.
