Scientists use geoengineering to lower global temperatures and fight malaria

Reflect sunlight back to space likely to improve mosquito populations

Experts say that geoengineering to prevent the worst effects of climate change could leave up to one billion people at risk of another case of malaria.

Removing carbon dioxide from the atmosphere to reduce heat capture and solar radiation management (SRM) – greater reflecting of sunlight from the planet in order to minimise heat absorption at all.

The study authors, who hail from Bangladesh, South Africa, and Germany, found that by deliberately adding aerosols to the stratosphere in order to cool down the tropics, use of SRM could protect some people living in high altitudes in East Africa but increase the spread of malaria in Lowland areas Sub-Saharan Africa and South Asia.
