2025年の先行研究が示した「GHG排出シナリオへの気候応答の鈍さ」という仮説を、改良した全球気候モデルで検証した研究。1870-2025年の実データでモデルを検証した上で、2026-2200年の6つのCO2排出シナリオをシミュレーションし、IPCC第6次評価報告書の結果と比較する。実現可能性と気候効果のバランスが最良のシナリオを特定し、政策立案者向けの accessible なツール提供を目指す。
English
This study tests a 2025 hypothesis that climate response is relatively insensitive to differing GHG emission scenarios, using an improved global climate model validated against 1870-2025 data. It simulates six CO2 emission scenarios for 2026-2200 and compares results with IPCC AR6. The paper identifies the scenario offering the best trade-off between feasibility and climate effectiveness, aiming to provide an accessible tool for policymakers.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本のGX政策・SSBJ開示・企業の脱炭素戦略に直接資する内容ではないが、長期シナリオ分析やTCFDシナリオ検討の基礎的知見として参考になり得る。
In the global GX context
Adds to the broader climate-science basis underpinning scenario analysis used in TCFD/ISSB disclosures, though it does not directly address disclosure frameworks or transition finance. Its claim of scenario insensitivity, if robust, would be relevant to long-horizon transition planning debates.

📄 Abstract(原文)
According to a predictive global climate model described and used in a recent study (April 2025), future climate change is relatively insensitive to various greenhouse gas (GHG) emission scenarios, despite their significant differences. The author concluded that it is likely necessary to move even closer to pre-industrial CO₂ concentrations to truly reverse the current trend. This work aims to verify this hypothesis using a "280 ppm" scenario and to reproduce the 2025 study with a more powerful tool. To do so, the article begins by rigorously justifying the innovative principles of the model, improving its reliability, and expanding the scope of the simulations. Validated by comparison with data covering the period 1870-2025, the improved model simulates six CO₂ emission scenarios for the period 2026-2200. The results obtained are then compared with others described in the Sixth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC). Finally, the scenario offering the best compromise between feasibility and climate effectiveness is identified. Thus, the scientific community, policymakers and more generally all those interested in the problems caused by climate change will have an easily accessible tool and new perspectives on climate strategies to adopt for the benefit of future generations and biodiversity.
