Geoengineering the climate would have massive repercussions for the health of billions of people at risk of malaria who live in tropical countries, according to a new finding by scientists at Georgetown University Medical Center and colleagues.
Geoengineering the climate would have massive repercussions for the health of billions of people at risk of malaria who live in tropical countries, according to a new finding by scientists at Georgetown University Medical Center and colleagues. The study appeared April 20, 2022, in Nature Communications.
This is the first assessment of how geoengineering the climate could impact the burden of infectious diseases. The study focuses on solar radiation management (SRM), an intervention that hypothesizes emergency actions aimed at reducing dangerous impacts of climate change. One action that has been proposed is injecting aerosols into the stratosphere that reflect incoming sunlight, thereby temporarily “pausing” global warming. Though SRM is often discussed as a way to reduce climate injustice, its potential impacts on health have seldom been studied.
“The implications of the study for decision-making are significant,” says Colin Carlson, PhD, an assistant research professor at the Center for Global Health Science and Security at Georgetown University Medical Center and lead author of the study. “Geoengineering might save lives, but the assumption that it will do so equally for everyone might leave some countries at a disadvantage when it comes time to make decisions. If geoengineering is about protecting populations on the frontlines of climate change, we should be able to add up the risks and benefits — especially in terms of neglected health burdens, such as mosquito-borne disease.”
