Interstate conflicts are complex and often have a multitude of causes. These factors can be social, economic, or cultural. One social factor receiving little attention in the literature is international migration. This paper uses climate shocks as a driver of emigration to study the causal impact of immigration on conflicts. We find that climate-induced immigration increases the probability that the destination country initiates a conflict against the origin. This effect is moderated by attitudes in the receiving country and features of the specific flows. The results imply that countries severely impacted by climate change may face an exodus of migrants and be forced to confront conflicts initiated by the destination countries of these migrants.

州际冲突很复杂，而且往往有多种原因。这些因素可以是社会的、经济的或文化的。文献中很少关注的一个社会因素是国际移民。本文使用气候冲击作为移民的驱动因素来研究移民对冲突的因果影响。我们发现，气候引起的移民增加了目的地国与原籍国发生冲突的可能性。这种影响受到接收国的态度和特定流量的特征的影响。结果表明，受气候变化严重影响的国家可能面临移民外流，并被迫面对由这些移民的目的地国发起的冲突。
