世界5地域の社会・気候結合モデルを構築し、地域ごとの緩和行動の変動性を分析。社会学習や規範が緩和意思を増幅し、排出シナリオに応じて気温上昇が数度変わることを示した。経済変数に加え社会・文化的要因の統合が予測に重大な影響を与える。
English
A coupled social-climate model stratified across five world regions reveals that support for mitigation evolves highly variably due to socio-economics, vulnerability, and temperature feedback. Social learning and norms can amplify or dampen mitigation, leading to temperature anomalies differing by several degrees under high emissions. Integrating social and cultural forces into climate models dramatically alters predictions.

日本のGX文脈において
日本では地域ごとの気候脆弱性や社会的受容性を考慮した緩和策が求められる。本モデルは、地域間の相互作用が日本を含む東アジアの温暖化対策に影響を与える可能性を示唆しており、SSBJや統合報告書におけるシナリオ分析への示唆となる。
In the global GX context
This study introduces a framework that couples social dynamics with climate models, highlighting how regional heterogeneity in mitigation behavior can amplify or reduce global warming. It underscores the importance of incorporating social feedbacks into climate policy design, relevant for global discussions on nationally determined contributions (NDCs) and just transition pathways.

📄 Abstract（原文）
How regional heterogeneity in social and cultural processes drive–and respond to–climate dynamics is little studied. Here we present a coupled social-climate model stratified across five world regions and parameterised with geophysical, economic and social survey data. We find that support for mitigation evolves in a highly variable fashion across regions, according to socio-economics, climate vulnerability, and feedback from changing temperatures. Social learning and social norms can amplify existing sentiment about mitigation, leading to better or worse global warming outcomes depending on the region. Moreover, mitigation in one region, as mediated by temperature dynamics, can influence other regions to act, or just sit back, thus driving cross-regional heterogeneity in mitigation opinions. Under high emissions scenarios, the peak temperature anomaly varies by several degrees Celsius depending on how these interactions unfold. Our model exemplifies an exploratory framework for studying how global geophysical processes interact with population-scale concerns to determine future sustainability outcomes. Many climate models now include economic variables, and this study shows how also integrating powerful social and cultural forces can dramatically alter predictions of both social and climate dynamics, and their diverse manifestation in world regions.
