'A world with 'rampant' malaria transmission is often seen as an inevitable consequence of global warming. But a new study radically challenges existing ideas of how the disease will spread with rising temperatures...'The effect of temperature is tiny when you look at everything else.' Factors like access to drugs and bed nets, the strength of a country's healthcare systems, and its wealth are orders of magnitude more important in predicting transmission'
'In the early days of global-warming research, scientists argued that warming would worsen malaria by increasing the range of mosquitoes' -- But 'In a recent paper, Peter Gething of Oxford University and his colleagues concluded that widespread claims that rising mean temperatures had already worsened malaria mortality were 'largely at odds with observed decreasing global trends'
'A study out today in Biology Letters finds that warmer temperatures seem to slow transmission of malaria-causing parasites, by reducing their infectiousness...the researchers, at PSU expect the pattern to apply to human malaria and possibly to other mosquito-borne diseases such as dengue fever and West Nile virus...As temperature rises, parasites do develop faster, but fewer of them become infectious'
