A new dynamic framework is required to assess adaptation limits
本文提出了一个评估气候变化适应极限的新方法框架，沿着适应路径评估极限，并提出了基于生物物理和社会经济数据的实证与模型研究策略，对国家和国际适应政策制定至关重要。
Anthropogenic climate change is already causing dangerous and widespread disruptions in global ecological and social systems and affects the lives of billions of people around the world. Even with scaled-up risk management and adaptation, the limits of adaptation will often be reached. Currently, very little is known about the degree to which societies can adapt to climate change, and where and when limits to adaptation will be reached. In this paper, we conceptualize adaptation limits through a novel methodological framework, assess adaptation limits along adaptation pathways, and propose a research strategy for empirical and model-based limits assessments based on biophysical and socio-economic data. Assessing limits is central to national and international adaptation policymaking. More efficient adaptation can also help climate mitigation efforts.
