Geoengineering to prevent the worst impacts of climate breakdown could expose up to a billion more people to malaria, scientists have found.

The report, published in Nature Communications, is the first assessment of how geoengineering the climate could affect the burden of infectious diseases.

Geoengineering includes removing carbon dioxide from the sky so the atmosphere will trap less heat, and solar radiation management (SRM) – reflecting more sunlight away from the planet so less heat is absorbed in the first place. The latter could be done in various ways, including spraying particles into the sky to reflect the sun…
