現在の排出削減と炭素除去中心の気候戦略では、温暖化の加速と危険な転換点を回避できないと主張。気候安定化をリスク管理問題として捉え、緩和・除去・冷却介入を統合したリスク比較枠組みを提案する。対応のタイムラインを気候脅威に合わせなければ、不可逆的な地球システム破壊の可能性が高まると警告する。
English
This paper argues that current climate strategies centered on emissions reduction and carbon removal are too slow to prevent dangerous tipping points. It proposes treating climate stabilization as a risk-management challenge, integrating mitigation, carbon removal, and cooling interventions within a comparative risk-risk framework. The authors warn that without aligning response timelines with accelerating climate threats, irreversible Earth-system disruption becomes more likely.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では、気候変動適応策やカーボンニュートラル戦略の策定に示唆を与える。特に、リスク評価の枠組みを政策に組み込む際の参考となる。ただし、冷却介入（ジオエンジニアリング）の議論は国内ではまだ馴染みが薄く、慎重な議論が必要。
In the global GX context
This paper contributes to the global debate on climate risk management, particularly the need to consider intervention risks alongside mitigation. It challenges the incremental policy approach and suggests a more integrated risk-based strategy, which could inform international climate policy discussions under the Paris Agreement and IPCC assessments.
👥 読者別の含意
🔬研究者:気候リスク評価の枠組みを拡張し、介入リスクと温暖化リスクの比較を提案する点が示唆的。
🏛政策担当者:気候政策のリスク管理アプローチへの転換を検討する際の参考になる。
📄 Abstract（原文）
Global warming is accelerating, yet current climate strategies centred on emissions reduction and carbon removal are unlikely to prevent temperatures from crossing dangerous tipping points. Although essential, these approaches operate too slowly to counter near-term warming driven by Earth’s growing energy imbalance, weakening carbon sinks, and amplifying climate feedbacks. This mismatch reflects systemic shortcomings in climate risk assessment that underestimate nonlinear risks and the escalating costs of delay. We argue that climate stabilisation should be treated as a risk-management challenge rather than an incremental policy process. This requires explicit comparison of intervention risks with those of continued warming. We outline a comparative risk–risk framework that integrates mitigation, carbon removal, and cooling interventions, and suggests that a viable strategy may require combining rapid decarbonisation and expanded carbon removal with carefully governed cooling interventions to limit near-term warming. Without aligning response timelines with accelerating climate threats, the likelihood of irreversible Earth-system disruption will continue to grow.
