Key developments include:\n\n### 1. **CMIP7 (Coupled Model Intercomparison Project Phase 7) Initial Results**\nThe World Climate Research Programme (WCRP) has officially launched CMIP7, with initial model outputs from over 30 global climate modeling centers now available through the Earth System Grid Federation (ESGF). CMIP7 models feature:\n- Higher spatial resolution (typically 25–50 km for atmosphere, 10–25 km for ocean models).\n- Enhanced representation of cloud microphysics and aerosol-cloud interactions.\n- Dynamic vegetation and permafrost carbon feedbacks.\n- Updated Shared Socioeconomic Pathways (SSPs) extended to 2300.\n\nFirst analyses indicate a refined equilibrium climate sensitivity (ECS) range of 2.8–4.2°C (median 3.5°C), slightly narrower than CMIP6 estimates. Projections under SSP2-4.5 now suggest a median global warming of 2.6°C by 2100 compared to pre-industrial levels.\n\n*Source: [WCRP CMIP7 Portal](https://www.wcrp-climate.org/cmip7)*\n\n### 2. **IPCC AR7 Draft Projections (Working Group I)**\nThe Intergovernmental Panel on Climate Change (IPCC) has released draft findings for its Seventh Assessment Report (AR7), scheduled for final publication in September 2026. Key updates include:\n- Sea level rise projections revised upward due to improved ice sheet modeling: Likely range of 0.5–1.1 m by 2100 under SSP5-8.5 (including marine ice cliff instability processes).\n- Increased confidence in regional precipitation shifts, particularly drying in southwestern North America and southern Africa.\n- Near-term warming (2026–2035) projected at 1.6–1.8°C above 1850–1900.\n\n*Source: [IPCC AR7 WG1 Draft Report](https://www.ipcc.ch/report/ar7/wg1/)* (access restricted to expert review","keywords":["climate-energy","climate-change","zo-research"],"about":[],"citation":[],"isPartOf":{"@type":"Dataset","name":"Forge Cascade Knowledge Graph","url":"https://forgecascade.org"},"publisher":{"@type":"Organization","name":"Forge Cascade","url":"https://forgecascade.org"}}
