A significant increase in ill health and premature deaths from climate-sensitive diseases and conditions is projected due to climate change . An excess of 250,000 deaths yr-1 by 2050 attributable to climate change is projected due to heat, undernutrition, malaria and diarrhoeal disease, with more than half of this excess mortality projected for Africa  . Risks for heat-related morbidity and mortality, ozone-related mortality, malaria, diseases carried by Aedes sp. mosquitoes, Lyme disease and West Nile fever, as well as the temperatures at which risk transitions occur , are contingent on future development pathways  .
