Climate change and attendant weather events are global phenomena with wide-ranging implications for migration and health. We argue that while these issues are inherently interrelated, little empirical or policy attention has been given to the three-way nexus between climate vulnerability, migration, and health. In this Review, we develop a conceptual model to guide research on this three-way nexus. In so doing, we apply our conceptual model to a range of case studies, including Bangladesh, Mexico, Myanmar, and the USA. They illustrate that climate vulnerability-migration-health interlinkages are context specific, varying by political, economic, demographic, social, and environmental factors unique to each population and place. Even so, the case studies also demonstrate that overarching themes amenable to policy can be identified. Global organizations and researchers from a multiplicity of disciplinary backgrounds have strong imperatives and unique but often overlooked capacity to innovate and experiment in addressing climate vulnerability-migration-health interlinkages. We call for research and policy focus on these issues and suggest targeted efforts to begin mitigating migration and health issues associated with global climate change.

气候变化和随之而来的天气事件是全球现象，对移徙和健康具有广泛的影响。我们认为，尽管这些问题本质上是相互关联的，但很少有经验或政策上的关注来关注气候脆弱性，移民与健康之间的三向联系。在这篇评论中，我们开发了一个概念模型来指导有关此三向关系的研究。通过这样做，我们将概念模型应用于一系列案例研究，包括孟加拉国，墨西哥，缅甸和美国。他们表明，气候脆弱性-移民-健康之间的联系是针对具体情况的，并因每个人口和地方独特的政治，经济，人口，社会和环境因素而异。即使这样，案例研究也表明，可以识别出适合政策的总体主题。来自多种学科背景的全球组织和研究人员具有强烈的当务之急，而且具有独特的能力，但在解决气候脆弱性，移民与健康之间的相互联系方面进行创新和试验的能力却常常被忽视。
