A Nature article complicates the conventional wisdom. The Economist's take away:

People who are thinking about what to do about malaria should bear in mind that the biological basis of its distribution may change in a warmer world. Those thinking about the overall danger that climate change represents should not spend their time worrying about its impact on malaria.

Bradford Plumer's two cents:

As the IPCC details in its chapter on climate and human health, malaria isn't the only disease-based problem we're likely to face in a warming worldthere's malnutrition, heat-wave deaths, shifting vectors for infectious and diarrheoal diseases, and so forth. Interestingly, the effects on malaria seemed to be the one thing this IPCC chapter was "mixed" about, even though malaria turned out to get all the headlines whenever the subject of global warming and disease came up. Let's see if this new study changes that.
