Climate change, weather shocks, and violent conflict: a critical look at the evidence
利用跨国数据，考察温度和降雨冲击是否引发暴力冲突，发现尽管媒体和政策制定者关注，但缺乏稳健证据支持天气冲击与冲突爆发之间的关联。
Abstract We use cross‐country data to explore whether temperature and rainfall shocks trigger violent conflict, or not. We include a wide range of country and time samples, and explore whether the impact of weather shocks is conditional on income or political regimes. Our overall conclusion is sobering. Notwithstanding the attention this topic has attracted from the media and policy makers, we find little robust evidence linking weather shocks to the onset of conflict.
