There is a rapidly growing literature on the link between climate change and poverty. This study reviews the existing literature on whether the poor are more exposed to climate shocks and whether they are more adversely affected. About two-thirds of the studies in the analyzed sample find that the poor are more exposed to climate shocks than is the rest of the population and four-fifths of the studies find that the poor are more adversely affected by climate shocks than is the rest of the population. Income and human capital losses tend to be concentrated among the poor. These findings highlight the potential long-term risk of a climate-change induced poverty trap and the need for targeted interventions to protect the poor from the adverse effects of climate shocks.
