米国の将来の気候影響評価に向けた研究課題とロードマップを提示(UW researchers among key contributors to new roadmap for future climate assessments)

米国ワシントン大学(University of Washington)の研究者8人を含む175人の研究者グループは、米国の将来の気候変動評価に向けた研究ロードマップを提示した。研究者らは、米国地球物理学連合(AGU)と米国気象学会(AMS)が立ち上げた特集論文集の最初の論評として、既存の科学的知見を統合し、気候リスク評価における研究課題と知識の不足を整理した。2025年4月、米国政府が第6次国家気候評価(NCA6)への資金提供を打ち切り、執筆に参加予定だった研究者らが解任されたことを背景に、継続的な気候評価の重要性を強調している。今後の評価では、海洋、都市、生態系、健康、大気質などの分野を横断し、地域ごとのリスクや対策の有効性、適応策の費用対効果を把握する必要がある。成果を政策立案や地域社会の意思決定に結び付け、気候変動への緩和・適応策を科学的根拠に基づいて進めることを目指す。

米国の将来の気候影響評価に向けた研究課題とロードマップを提示(UW researchers among key contributors to new roadmap for future climate assessments)

Abstract

Scientific assessments play a critical role in synthesizing evidence to support evidence-based decision-making in many sectors and topics. For climate change, large-scale assessments like the Intergovernmental Panel on Climate Change (IPCC) and the United States (U.S.) National Climate Assessment (NCA) reports help many different users—from national government to local governments, Indigenous Peoples and communities, the private sector, the social sector, and the scientific community itself—navigate the complex field of climate risks, impacts, and integrated solutions. While co-creation with users is essential to developing actionable assessments, this paper lays the groundwork for future processes by identifying many advancing and emerging areas of relevant knowledge ready for assessment or additional near-term research. Drawing on the expertise of many scholars who were formerly tasked with producing the Sixth NCA and authors of other national or sub-national climate assessment reports, this paper highlights select U.S.-relevant topics in which research advances since the 2023 Fifth NCA make new syntheses particularly valuable for future national, sub-national, and sectoral climate assessments. It also identifies critical research topics in those select areas that would be useful for future climate assessment efforts. Overall, this research priorities roadmap aims to catalyze collaborations, research, and a network of climate assessments to synthesize the state of climate impacts, risks, and responses and to provide widely accessible and foundational information for sectoral, regional, and cross-cutting climate action plans and decisions in the U.S.
