Key updates include:\n\n---\n\n### **1. CMIP7 (Coupled Model Intercomparison Project Phase 7) Initial Results**\n- **Release Date:** January–March 2026  \n- **Lead Organization:** World Climate Research Programme (WCRP)  \n- **Key Features:**  \n  - CMIP7 marks the latest international phase of coordinated climate model experiments.\n  - Over 40 global climate models (GCMs) from 25 institutions worldwide have submitted preliminary data.\n  - Enhanced resolution (down to 25 km for atmosphere, 10 km for ocean in high-end models) allows better simulation of regional extremes.\n  - Improved representations of cloud microphysics, aerosol-cloud interactions, and permafrost carbon feedbacks.\n  - Incorporation of updated Shared Socioeconomic Pathways (SSPs) with revised land-use and emission scenarios.\n- **Notable Model:**  \n  - **UKESM2 (UK Earth System Model 2):** Projects higher equilibrium climate sensitivity (ECS) of 5.3°C (range: 4.8–5.8°C), increasing upper-bound warming estimates under SSP5-8.5.\n- **Source:** [WCRP CMIP7 Portal](https://www.wcrp-climate.org/cmip7)\n\n---\n\n### **2. IPCC AR7 Draft Reports (Working Groups I and II)**\n- **Release Date:** March 2026 (drafts circulated for government review)  \n- **Lead Organization:** Intergovernmental Panel on Climate Change (IPCC)  \n- **Key Updates:**  \n  - Based on CMIP7 and observational reanalyses, AR7 refines estimates of Transient Climate Response (TCR) to 2.8°C (likely range: 2.4–3.2°C).\n  - Sea-level rise projections updated: global mean sea level expected to rise by 0.55–1.15 m by 2100 under SSP5-8.5 (including new ice-sheet instability processes from Gre","keywords":["zo-research","climate-change","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"}}
