Malaria transmission peaks at 25°C, so intentional cooling could affect billions by shifting the risk of malaria as the planet heats up. Malaria transmission peaks at 25°C, and a planet too hot for humans is also too hot for malaria transmission, says lead author Dr. Colin Carlson, of Georgetown’s Center for Global Health Science and Security. Parts of Brazil, Peru, Ecuador, Venezuela and Mozambique were all countries that would see a decreased risk of malaria at high levels of global warming. The scientists ran both medium and high warming scenarios for the study, comparing the results with and without SMR geoengineering. “Our study highlights that the frontlines of climate injustice aren’t one monolithic bloc, especially when it comes to health.”
