The Paris Agreement put adaptation prominently on the global climate action agenda. Despite a surge in research and praxis-based knowledge on adaptation, a critical policy roadblock is synthesizing and assessing this burgeoning evidence. We develop an approach to assess the multidimensional feasibility of adaptation options in a robust and transparent manner, providing direction for global climate policy and identifying knowledge gaps to further future climate research. The approach, which was tested in the IPCC Special Report on 1.5 °C (SR1.5) to assess 23 adaptation options, is underpinned by a systematic review of recent literature, expert elicitation, and iterative peer review. It responds to the challenge of limited agreement on adaptation indicators, lack of fine-scale adaptation data, and challenges of assessing synergies and trade-offs with mitigation. The findings offer methodological insights into how future assessments such as the IPCC Assessment Report (AR) six and regional, national, and sectoral assessment exercises could assess adaptation feasibility and synthesize the growing body of knowledge on climate change adaptation.

评估适应方案的可行性：气候适应研究和实践的方法学进步和方向

《巴黎协定》将适应列入全球气候行动议程的显着位置。尽管关于适应的研究和基于实践的知识激增，但一个关键的政策障碍是综合和评估这一新兴证据。我们开发了一种方法，以稳健和透明的方式评估适应方案的多维可行性，为全球气候政策提供方向并确定知识差距以进一步开展未来的气候研究。该方法在 IPCC 特别报告中针对 1.5 °C (SR1.5) 进行了测试，以评估 23 种适应选项，并以对近期文献、专家引出和迭代同行评审的系统审查为基础。它应对了在适应指标上达成的共识有限、缺乏精细的适应数据、以及评估与缓解措施的协同作用和权衡的挑战。研究结果为未来评估（如 IPCC 评估报告 (AR) 6 以及区域、国家和部门评估活动）如何评估适应可行性并综合不断增长的气候变化适应知识体系提供了方法论见解。
