Does global warming worsen poverty and inequality? An updated review
综述了气候变化尤其是全球变暖对贫困和不平等影响的最新研究，发现高温对贫困有持续负面影响，尤其加剧撒哈拉以南非洲的脆弱性，但对不平等的影响尚无定论。基于全球子国家数据，温度变化短期影响更大，且对长期贫困的影响大于暂时贫困。
Abstract We offer an updated and comprehensive review of recent studies on the impacts of climate change, particularly global warming, on poverty and inequality, paying special attention to data sources as well as empirical methods. While studies consistently find negative impacts of higher temperatures on poverty across different geographical regions, with higher vulnerability especially in poorer Sub‐Saharan Africa, there is inconclusive evidence on climate change impacts on inequality. Further analyzing a recently constructed global database at the subnational unit level derived from official national household income and consumption surveys, we find that temperature change has larger impacts in the short term and more impacts on chronic poverty than transient poverty. The results are robust to different model specifications and measures of chronic poverty and are more pronounced for poorer countries. Our findings offer relevant inputs into current efforts to fight climate change.
