The impacts of environmental change on human outcomes often depend on local exposures and behavioral responses that are challenging to observe with traditional administrative or sensor data. We show how data from private pollution sensors, cell phones, social media posts, and internet search...

Steady improvements in ambient air quality in the US over the past several decades have led to large public health benefits, and the policies that helped drive these improvements are considered landmarks in successful environmental policymaking. However, recent trends in PM2.5 concentrations, a...

Accurate estimation of air quality impacts on health outcomes is critical for guiding policy choices to mitigate such damages. Estimation poses an empirical challenge, however, because local economic activity can simultaneously generate changes in both air quality and in health impacts that are...

Accurate and comprehensive measurements of a range of sustainable development outcomes are fundamental inputs into both research and policy. We synthesize the growing literature that uses satellite imagery to understand these outcomes, with a focus on approaches that combine imagery with machine...

The effect of hot temperatures on labor productivity is thought to be a key channel through which a warming climate will impact the economy, and these impacts could help explain broader observed relationships between temperature and economic output. Yet for many workers and jobs, especially the...

Increased temperature-related mortality is predicted to be one of the largest contributors to future economic damages from climate change globally, with declines in cold-related deaths in some regions outweighed by increases in heat-related deaths in others. Changes in temperature could also...

Wildfire activity has increased in the US and is projected to accelerate under future climate change. However, our understanding of the impacts of climate change on wildfire smoke and health remains highly uncertain. We quantify the past and future mortality burden in the US due to wildfire...

We study whether the sensitivity of economic, health, and livelihood outcomes to climate extremes has declined over the last half century, consistent with adaptation. Understanding whether such adaptation is already occurring is central to anticipating future climate damages, to calibrating the...

Air pollution is known to negatively affect a range of health outcomes. Wildfire smoke is an increasingly important contributor to air pollution, yet extreme smoke events are highly salient and could induce behavioral responses that alter health impacts. We combine geolocated data covering the...
