海水の侵入により、淡水熱帯泥炭地が塩性化し炭素を放出する「塩害崩壊」というフィードバックが発生している可能性を指摘。植生の枯死、酸化、火災リスクの増大により、長期的な炭素吸収源が温室効果ガスの発生源に転換する。現在の全球気候モデルやIPCCの枠組みはこのプロセスを無視しており、沿岸炭素収支や脆弱性評価に乖離が生じている。
English
This paper synthesizes evidence that seawater intrusion into freshwater tropical peatlands may trigger a 'salted collapse' feedback, converting carbon sinks into sources via vegetation dieback, oxidation, and fire risk. Current global climate models and IPCC accounting frameworks omit this process, risking underestimation of coastal carbon fluxes and human vulnerability. Recognizing salinization as a coupled geophysical and socio-ecological tipping point is essential.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本は沿岸泥炭地が限定的だが、海面上昇による炭素循環の変化は全球の気候予測に影響を与える。IPCCやSSBJ等の枠組みで考慮されていないフィードバックを提起しており、国際的な炭素会計の精度向上に寄与する知見。
In the global GX context
This paper highlights a missing feedback in global carbon budgets relevant to TCFD/ISSB scenario analysis and IPCC assessments. It underscores the need to incorporate coastal peatland salinization into climate models and corporate carbon accounting, especially for firms with tropical supply chains.
👥 読者別の含意
🔬研究者:Researchers studying climate feedbacks should note the 'salted collapse' mechanism as a potentially significant unaccounted carbon source.
🏛政策担当者:Policymakers in tropical regions should consider salinization impacts on carbon accounting and adaptation strategies.
📄 Abstract（原文）
Coastal tropical peatlands store vast carbon reserves now threatened by accelerating sea level rise. We synthesize emerging evidence showing that seawater intrusion may be triggering an overlooked Earth system feedback: the transformation of freshwater peatlands into saline, carbon‐emitting landscapes. This process, which we frame as “salted collapse”, could trigger vegetation dieback, oxidation, and fire risk, converting long‐term carbon sinks into persistent greenhouse gas sources. The biogeochemical transition may also cascade into social systems, undermining coastal agriculture, food security, and adaptation capacity across low‐lying tropical regions. Yet current global climate models and IPCC accounting frameworks omit this feedback, risking underestimating coastal carbon fluxes and associated human vulnerability. Recognizing salinization as a coupled geophysical and socio‐ecological tipping process is essential for closing the coastal carbon budget and integrating these landscapes into global climate models, accounting frameworks, and adaptation strategies.
