1815年タンボラ級の火山噴火を気候ショックのアナロジーとし、気候シミュレーションと再エネ資源・コスト評価を組み合わせて世界の風力・太陽光発電への影響を推計した。風力・太陽光資源は平均3.6%減少し最大20カ月持続、現行インフラ下で213.5TWh（カリフォルニア州の年間電力消費に相当）と90億ドルの損失が生じる。影響は地域的に不均一で、物理的感応度とシステム露出が乖離することを示す。
English
Using a Tambora-scale eruption as an analogue for abrupt aerosol-driven climate disruption, the authors combine climate simulations with renewable resource and cost estimates to assess global wind and solar impacts. They find a concurrent 3.6% mean resource decline persisting up to 20 months, translating to 213.5 TWh and USD 9.0 billion in losses under current infrastructure. Impacts are regionally heterogeneous, revealing a decoupling between physical sensitivity and system exposure.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本は再エネ比率の拡大と電源の海外依存が進む中、低頻度・高影響の気候ショックを長期エネルギー計画や電源ポートフォリオのリスク評価に組み込む必要性を示唆する。SSBJやTCFDのシナリオ分析において、物理的リスクの裾野事象をどう扱うかという論点に接続する。
In the global GX context
This paper broadens the physical-risk taxonomy used in TCFD/ISSB scenario analysis by introducing low-frequency, high-impact volcanic aerosol shocks as a renewable-supply risk. It also speaks to debates on aerosol-based climate intervention (SRM), relevant to emerging disclosure and governance discussions on geoengineering.

📄 Abstract（原文）
<title>Abstract</title> <p>Weather-dependent renewable energy systems are increasingly exposed to climate variability, yet the consequences of rare, high-impact climate shocks for renewable electricity supply remain poorly understood. Here we use a volcanic eruption the size of the 1815 Tambora one as a analogue for an abrupt climate disruption caused by stratospheric aerosols, combining climate simulations with renewable resource and cost-based impact estimates to assess impacts on global wind and solar power. We find a concurrent global decline in wind and solar resources, with a mean reduction of 3.6% persisting for up to 20 months. Under present-day infrastructure, these anomalies correspond to an estimated 213.5 TWh loss in renewable electricity generation—comparable to California's annual electricity consumption in 2024—and USD 9.0 billion in associated cost-based losses. Impacts are regionally heterogeneous and reveal a marked decoupling between physical sensitivity and system exposure. South America and Africa exhibit the largest mean resource reductions, whereas Asia incurs the largest absolute generation losses because of its concentrated installed capacity. Our results identify major volcanic aerosol forcing as a previously underexplored source of renewable electricity risk and highlight the importance of incorporating low-frequency climate shocks into long-term energy planning and assessments of aerosol-based climate intervention.</p>
