Add malaria to the ever growing list of problems blamed on global warming with little or no actual evidence to support such a connection. Paul Reiter--director of the Insects and Infectious Diseases Unit of the Institut Pasteur, Paris--and Roger Bate debunk the latest Global Warming Nonsense in today's WSJ:
The concept of malaria as a "tropical" infection is nonsense. It is a disease of the poor. Alarmists in the richest countries peddle the notion that the increase in malaria in poor countries is due to global warming and that this will eventually cause malaria to spread to areas that were "previously malaria free." That's a misrepresentation of the facts and disingenuous when packaged with opposition to the cheapest and best insecticide to combat malaria – DDT.
It is true that malaria has been increasing at an alarming rate in parts of Africa and elsewhere in the world. Scientists ascribe this increase to many factors, including population growth, deforestation, rice cultivation in previously uncultivated upland marshes, clustering of populations around these marshes, and large numbers of people who have fled their homes because of civil strife. The evolution of drug-resistant parasites and insecticide-resistant mosquitoes, and the cessation of mosquito-control operations are also factors.
Of course, temperature is a factor in the transmission of mosquito-borne diseases, and future incidence may be affected if the world's climate continues to warm. But throughout history the most critical factors in the spread or eradication of disease has been human behavior (shifting population centers, changing farming methods and the like) and living standards. Poverty has been and remains the world's greatest killer.
Serious scientists rarely engage in public quarrels. Alarmists are therefore often unopposed in offering simplicity in place of complexity, ideology in place of scientific dialogue, and emotion in place of dry perspective. The alarmists will likely steal the show on Capitol Hill today. But anyone truly worried about malaria in impoverished countries would do well to focus on improving human living conditions, not the weather.
As Bjorn Lomborg has argued for years, spending billions (trillions?) of dollars to try to prevent something that may not actually be all that bad and that we may have little or no real ability to impact at all seems ridiculous when that money could otherwise be spent solving real problems that we know we can correct.
UPDATE: Those of you always looking for the local angle (like JB), will appreciate this:
Minnesota has developed into the nation's state-level combat zone on global warming, where groups and individuals have aligned to oppose what their state's climate commission is trying to sell them. Republican Gov. Tim Pawlenty, who many political observers perceive is angling for the vice presidential nomination, has invested his credibility and stature heavily in the issue, especially as chair of the National Governors Association. The blowback began in February when fellow executives from other states took him behind the woodshed.
The resistance elevated last month when one of the state's free-market think tanks, the Center of the American Experiment, brought in economist Dr. Margo Thorning of the American Council for Capital Formation to discuss the staggering costs that would result from federal and state proposals to reduce greenhouse gases
Yesterday another bomb dropped in St. Paul: a coalition of free-marketers, property rights, social conservatives, state legislators, and disaffected members of the Minnesota Climate Change Advisory Group held a press conference at the legislature and released two separate reports criticizing the junk economics, alarmist climate forecasts, and nonexistent feasibility study of the proposals coming from MCCAG. Minnesota Majority, the social conservatives, and the American Property Coalition joined forces to commission the Beacon Hill Institute to critique the MCCAG's recommendations (PDF). The Minnesota Free Market Institute also did their own study. For once local mainstream media outlets were virtually forced to report that more than just a small, dissenting group of "deniers" or "skeptics" oppose dramatic increases in energy costs that will come from these global warming "solutions."
