In 2018, a commentary in Nature Climate Change by Colin Carlson and Christopher Trisos cautioned against the aftereffects of geoengineering, as it could significantly impact global health. Find out more at Engineering
But what if we could be proactive and meddle with the Earth's thermostat, controlling radiation from the sun? . It said that geoengineering was"a broad set of methods and technologies operating on a large scale that aim to deliberately alter the climate system in order to alleviate the impacts of climate change".
These techniques can be divided into categories such as solar radiation management , which intends to cool the Earth by reflecting sunlight into space; and, which aims to remove and permanently sequester carbon dioxide from the atmosphere, resulting in negative emissions. “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," said Carlson, lead author of the study.
in two future scenarios, with medium or high levels of global warming, with and without geoengineering.mosquitoWhile medium- and high-warming scenarios revealed that malaria risk could shift significantly between regions, the high-warming scenario revealed that a billion extra people were at risk of malaria in the“On a planet that’s too hot for humans, it also gets too hot for the malaria parasite,” said Carlson.
“We’re so early in this process that the conversation is still about increasing Global South leadership in geoengineering research. Our study highlights that the frontlines of climate injustice aren’t one monolithic bloc, especially when it comes to health,” said Carlson.Stay ahead with the latest science, technology and innovation news, for free:
