Africas malaria resurgence isnt down to global warming
Climate in upland East Africa hasnt changed yet.

Climate change cannot explain the growth of malaria in the highlands of East Africa, say researchers. Drawing simplistic links between global warming and local disease patterns could lead to mistaken policy decisions, they warn.
Drug resistance, or the failure of the health-care system to keep pace with population growth, are more likely culprits for malarias rise, say Simon Hay, of the University of Oxford, and his colleagues. These should be the focus of public-health efforts, they urge. Malaria kills between one million and two million Africans each year.
Blowing hot and cold
"Theres been some terrible bandwagon-jumping and misdirection of resources that could be spent learning how to control mosquito-borne disease," says Reiter. "We urgently need to cool down the rhetoric and start to look objectively at what the factors behind their recent resurgence are."
But this study does not prove that theres no link between climate change and the growth of malaria in these regions, says Jonathan Patz, who studies climates relationship with health at Johns Hopkins University in Baltimore.
Some regions of East Africa do show warming trends, he says. That the team considered climate over a much longer period than they analysed disease could have confused their analysis, he believes.
"I think theres a mismatch between the results and the strong conclusions of this paper," says Patz. He feels its still not clear whether climate change has influenced disease.
Whats needed, he says, are studies that consider climate, disease statistics and social factors simultaneously. These may help to predict the effect on malaria if climate in upland East Africa does change.

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
