Mortality and morbidity will escalate with further global warming, placing additional strain on health and economic systems . Above 2℃ of global warming, distribution and seasonal transmission of vector-borne diseases is expected to increase, exposing tens of millions more people, mostly in west, east and southern Africa . Above 1.5℃ risk of heat-related deaths rises sharply , with at least 15 additional deaths per 100,000 annually across large parts of Africa, reaching 50-180 additional deaths per 100,000 people annually in regions of North, West, and East Africa for 2.5ºC, and increasing to 200-600 per 100,000 people annually for 4.4℃. Above 2℃ global warming, thousands to tens of thousands of additional cases of diarrhoeal disease are projected, mainly in west, central and east Africa . These changes risk undermining improvements in health from future socioeconomic development .
