We investigate the long-run effects of cooling on conflict. We construct a geo-referenced and digitized database of conflicts in Europe, North Africa, and the Near East from 1400-1900, which we merge with historical temperature data. We show that cooling is associated with increased conflict....

This paper investigates the long-run effects of climate change on conflict by examining cooling from 1400-1900 CE, a period that includes most of the Little Ice Age. We construct a geo-referenced and digitized database of conflicts in Europe, North Africa, and the Near East from 1400-1900, which...

There is a large empirical literature trying to quantify the potentially adverse affects of climate change on the risk of violent armed conflict, which focuses almost exclusively on linking annual variation in climatic conditions to violence. A major shortcoming of this approach is that it...
