CMIP7 (Coupled Model Intercomparison Project Phase 7) Initial Results**\n- The World Climate Research Programme (WCRP) launched CMIP7 in late 2025, with the first wave of simulations from institutions including the UK Met Office, NOAA, NCAR, and the Max Planck Institute for Meteorology becoming available in early 2026.\n- CMIP7 models feature higher spatial resolution (down to 1–2 km for atmosphere in some regional models), improved representation of cloud microphysics, ice sheet dynamics, and carbon-cycle feedbacks.\n- Preliminary results indicate a median equilibrium climate sensitivity (ECS) of 3.4°C (range: 2.9–4.1°C), slightly higher than CMIP6's 3.1°C, suggesting greater warming under high-emission pathways.\n- Source: [WCRP CMIP7 Portal](https://www.wcrp-climate.org/cmip7)\n\n**2. IPCC AR7 Working Group I Report (January 2026)**\n- The Intergovernmental Panel on Climate Change (IPCC) released its Seventh Assessment Report (AR7) Working Group I contribution, \"The Physical Science Basis,\" in January 2026.\n- The report confirms that global mean surface temperature reached +1.45°C above pre-industrial (1850–1900) levels in 2025, the warmest on record.\n- Under SSP2-4.5, median warming is projected to reach 2.4°C by 2100; under SSP5-8.5, warming reaches 3.7°C. A new low-emission scenario (SSP1-1.9) shows a 58% chance of limiting warming to 1.5°C if global CO₂ emissions reach net zero by 2042.\n- Improved ice sheet models suggest potential sea level rise of up to 1.2 meters by 2100 under high emissions, with West Antarctic instability more explicitly simulated","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"}}
