Abstract:Environmental sustainability remains at risk, given the coupled trends of economic development with air pollution. The risk is even greater in the water-stressed world, given the debated suppression effects of air pollutants on rain formation. Here, we tested this suppression in the water-stressed South Africa, by fitting generalized linear models to a 21-year historical dataset of rainfall and air pollutants. Some gaseous pollutants and PM10 show a significant negative correlation with rainfall, perhaps due t… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
