本論文は、地域の気候計画における地球温暖化レベル（GWL）の枠組みの重要性を論じ、CMIP5からCMIP6への移行に伴う不確実性を軽減する方法を示す。Cal-Adaptの事例を通じて、GWLがシナリオ非依存で堅牢な分析を可能にし、エネルギー部門の適応計画を国際目標に整合させることを強調する。
English
This paper discusses the importance of the Global Warming Level (GWL) framework in regional climate planning, mitigating uncertainties from the CMIP5 to CMIP6 transition. Using Cal-Adapt as an example, it shows how GWL enables scenario-agnostic, robust analyses, aligning energy sector adaptation with international targets.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では、気候変動適応計画やエネルギー基本計画において、地域ごとの気候リスク評価が重要視されている。GWLアプローチは、日本の自治体や電力会社が長期的な設備投資や防災計画を策定する際に、科学的に一貫した基準を提供する。
In the global GX context
Globally, the GWL framework aligns with the Paris Agreement and supports climate risk disclosure under TCFD and ISSB. It offers a consistent method for companies to assess physical risks across different climate scenarios, aiding transition planning and investor communication.

📄 Abstract（原文）
As climate change accelerates, local communities require scientifically sound localized climate data to build resilience against extreme hazards like heatwaves, droughts, and intense precipitation. However, regional climate planning has traditionally been hindered by a lack of common climate analysis approaches and rapidly evolving climate modeling frameworks. In addition, the transition from Coupled Model Intercomparison Project Phase 5 (CMIP5) to CMIP6 introduced new emissions scenarios (Shared Socioeconomic Pathways - SSP) and a "hot model problem": where several advanced models project overly high global climate sensitivities. These factors create significant uncertainty regarding when specific warming thresholds will be reached, making long-term regional planning and cross-generational report comparisons highly complex and tedious. To mitigate these challenges, the international scientific community has increasingly adopted the Global Warming Level (GWL) approach. Rather than asking what a region will look like in a specific year (e.g., 2050), the GWL framework assesses what a region looks like at specific increments of global warming (e.g., 1.5°C or 2.0°C above pre-industrial levels). Cal-Adapt operationalizes the GWL framework for regional climate planning, enabling scientifically robust, scenario-agnostic analyses that remain consistent across generations of climate projections, reduces biases associated with differing model climate sensitivities, and aligns adaptation decisions with international climate targets such as the Paris Agreement. Realizing the full potential of GWL planning will require coordinated investment across the climate adaptation community.
