Climate change may reduce malaria suitability in already‑hot lowland tropics (where transmission is currently intense) while expanding risk into cooler highlands and marginal zones; the net global effect depends on what happens in the high-burden regions of West and Central Africa. That means future malaria policy must couple climate projections, local temperature‑suitability curves, and region‑specific control capacity rather than assuming uniform worsening.
— This reframes climate–disease debate from a simple 'more warming = more malaria' slogan into a regionally uneven risk map that has major implications for where to invest in health systems and adaptation.
