Thomas Fuller of the San Francisco Examiner has a great piece which summarizes the issue of climate and malaria and Mann. Like with the imagined increase in hurricane frequency due to global warming, so it goes with malaria. There’s no correlation. The premise is false.
On Monday, May 17th, I had the privilege of sitting on a panel at the Heartland Institute Chicago ICCC4 conference with regular WUWT contributor Dr. Indur Goklany. He gave his views on the declining mortality we’ve seen worldwide and has published several pieces here on WUWT. He also the author of the book: “ The Improving State of the World”. “Goks” (as his friends call him) gave a PowerPoint presentation on declining mortality in a warming world and you can view the PPT File here.
I’ve culled one of the slides he presented below. If this doesn’t offer proof that when it comes to mankind that “warmer is better”, I don’t know what would. Note the reversal in the southern hemisphere with Australia and New Zealand.
But the most interesting slide is number 10, showing the drop in Malaria worldwide:
Thomas Fuller covers the Mann-Malaria issue below:
Correspondent Barry Woods has done all the heavy lifting on this story, so if you like it, kudos to him–any errors of course are my responsibility.
In the Guardian today there is an article following on about the story of malaria and climate change. I like the quote from Peter Gething of Oxford: “If we were to go back to the 1900s with the correct climate change predictions for the 20th century, modellers would predict expansion and worsening of malaria and they would have been wrong, and we believe they are wrong now.” That’s because despite global warming for the past 30 years, the geographic extent of malaria has lessened, leading logical thinkers to guess that climate change has not worsened the spread of malaria.
Gething was referring to his study published yesterday in Nature that found that bednets and drugs will influence the spread of malaria far more than will climate change, challenging fears that warming will aggravate the disease in Africa.
Many researchers have predicted that rising temperatures will cause malaria to expand its range and intensify in its current strongholds. But unlike usual models, which aim to predict how climate change will affect malaria in the future, researchers looked at how warming affected the disease throughout the last century.
They used a recent epidemiological map of the global distribution of the major malaria parasite Plasmodium falciparum, and compared this with historical data on malaria’s prevalence in the 1900s.
The researchers — whose work was published in Nature yesterday (20 May) — found that despite global warming, the prevalence of malaria decreased, which they attribute to disease and mosquito control programmes.
Or so you would think. But Matthew Thomas thinks differently. Matthew Thomas said that the study “plays down the potential importance of climate [change]”.
Who is Matthew Thomas? He is a researcher at… Penn State. Matthew Thomas is a researcher… at Penn State… who has just won a $1.8 million grant to study the influence of environmental temperature on transmission of vector-borne diseases. Think he has a dog in this hunt?
Ask his co-investigator on the project. Michael Mann…
Where do we ask for a refund?
