Research published in Nature warns that climate change may result in over 500,000 additional malaria deaths across Africa by 2050.This alarming projection stems from the anticipated intensification of extreme weather events, such as floods and cyclones, which significantly disrupt healthcare services and exacerbate the spread of malaria in vulnerable populations.

noticiasambientales.comMalaria, which predominantly affects children under the age of five, is already a major health challenge in Africa, accounting for 95% of global cases and deaths related to the disease.The World Health Organization (WHO) estimated that around 610,000 people died from malaria in 2024 alone.
The researchers emphasize that the greatest threat to malaria control in Africa arises not merely from ecological changes, but from the persistent disruption of essential services due to extreme weather events.

carbonbrief.orgThe study highlights that while rising temperatures and shifting rainfall patterns do contribute to the spread of malaria, the overwhelming factor is the disruptive impact of extreme weather.The authors found that about 67% of the African population will see an increased risk of contracting malaria as a result of climate change by the middle of the century.
The authors used sophisticated mathematical models to assess the ecological impacts of climate change on mosquito populations and malaria transmission.Their findings suggest that the ecological effects of climate change may only cause a minimal increase in malaria cases—about 0.12%—by 2050.However, this figure masks extensive regional variation, with some areas witnessing significant increases in malaria rates while others may see decreases.

The implications of climate change on malaria in Africa are indicative of a broader health crisis exacerbated by global warming.Climate change is projected to cause approximately 250,000 additional deaths per year by 2050 due to undernutrition, malaria, and other climate-sensitive diseases.
