本論文は、気温上昇とバイオエネルギーや森林再生などの土地利用集約型の緩和策が、生物多様性の避難所である気候レフュジアに与える影響を、複数の統合評価モデルを用いて分析した。1.5℃目標に沿った積極的な気候対策は、現在の政策と比較して気候レフュジアの損失を50%以上削減できる。ただし、地域差やモデル間の差異、生物多様性の回復仮定によって結果が大きく異なる。
English
This paper analyzes how warming and land-intensive mitigation (afforestation, bioenergy) affect climate refugia—areas sheltering biodiversity—using five integrated assessment models. Decisive climate action limiting warming to 1.5°C reduces combined loss of refugia by over 50% compared to current policies. Overshoot impacts depend on biodiversity recovery assumptions, with regional and model differences.

In the global GX context
Globally, this paper informs the IPCC and UNFCCC on overshoot scenarios and their biodiversity implications, adding to the debate on land-based mitigation trade-offs. It is relevant for ISSB/TCFD scenario analysis that considers biodiversity and climate interactions.

📄 Abstract（原文）
Abstract Biodiversity loss is expected to escalate with every increment of global warming. Simultaneously, land-intensive climate change mitigation strategies, such as afforestation and bioenergy, may further compound biodiversity loss. So far, the magnitude of these two drivers has not been compared in the context of temperature overshoot, meaning the temporary exceedance of a targeted global warming limit. By combining spatial data on climate refugia (areas sheltering biodiversity from climate change), bioenergy cropland, and forestation for multiple cost-effective scenarios with varying levels of climate action and overshoot, we illustrate how both warming and mitigation affect today’s climate refugia across five integrated assessment models. Decisive climate action, compatible with limiting warming to 1.5 °C, reduces the combined loss of today’s climate refugia due to warming and mitigation-related land-use change by more than 50% compared to current climate policies, outweighing potentially negative implications of mitigation at the global level by limiting the magnitude and duration of warming above 1.5 °C. We observe notable differences across regions and the considered model frameworks. Overshoot implications strongly depend on the underlying biodiversity recovery assumptions.
