摘要：

Exploring cost-effective climate adaptation strategies is crucial for human well-being, yet little is known about whether and how information interventions promote climate adaptation. This paper provides the first analysis of the role of weather forecasts in reducing the health impacts of climate change, utilizing large-scale, fine-grained medical expenditure data from China’s largest medical insurance program. Our analysis reveals accurate forecasts significantly reduce weather-related medical cost: a one-degree Celsius deviation from the accurate forecast increases medical expenses over the next seven days by 13.7% when underestimating and 4.6% when overestimating the realized temperature. Moreover, the potential value of improving forecast accuracy will escalate with ongoing global warming, as the negative impacts of inaccurate forecasts are especially severe under extreme weather conditions. Our findings highlight the substantial potential of information interventions for climate adaptation and enhance understanding of health-related impacts of climate change.
