Recent years have seen a massive increase in malaria in Africa. In some parts of the continent, malaria mortality in young children almost doubled from the 1980s and the 1990s, and the disease now kills 3,000 people a day.
In this article, Christopher Thomas reports on the findings of a number of studies that have investigated whether climate change could be behind this resurgence.
Several studies have projected that global climate change will increase future malaria transmission in Africa. But the link between contemporary changes in malaria and climate is hotly disputed.
