DDT

Category archives for DDT

Yale Environment 360 has damaged its credibility by publishing a piece by Fred Pearce claiming: When Rachel Carson’s sound case against the mass application of DDT as an agricultural pesticide morphed into blanket opposition to much smaller indoor applications to fight malaria, it arguably resulted in millions of deaths as the diseases resurged. But the…

In this piece Roger Bate, Donald Roberts and Richard Tren accuse the UN of “Scientific Fraud against DDT”. Their Accusation is based on an Opinion paper by Roberts and Tren published in Research and Reports in Tropical Medicine. So let’s look at their paper and see where the “Scientific Fraud” is. Roberts and Tren’s key…

With Donald Roberts about to give testimony before Congress it is instructive to look at his Senate testimony on October 6, 2004. Just as the use of DDT in house spraying brought spectacular reductions in malaria, declining use of house spraying brought spectacular increases in malaria. … Data from Asian countries show similar relationships. Figures…

Skeptoid fact check part 2

In part 1 of this fact check I examined Brian Dunning’s assertions that DDT did not thin eggshells. Responses from Orac: “Dunning should know better”, Bug Girl: “Dunning clearly got his information second-hand. And it was bad information.”, and Dunning: I think I’ve repeated that Milloy was not one of my sources enough times. I…

Skeptoid fact check part 1

Brian Dunning’s Skeptoid does an excellent job of debunking pseudoscience, so his podcast on DDT is profoundly disappointing. Dunning claims that DDT use did not have a large impact on bird populations, that elitist environmental groups were killing brown children by blocking DDT use and that DDT is effective even if mosquitoes are resistant. None…

Stewart Brand disappoints

In an earlier post So George Monbiot challenged Brand to notice and announce that he’s wrong about DDT. So far it hasn’t happened. Unless it does, I think we should be skeptical about the rest of Brand’s thesis. Well, as Monbiot relates, it still hasn’t happened. It seems increasingly likely that Brand will destroy his…

What Channel 4 Got Wrong

Following in the footsteps of The Great Global Warming Swindle Channel 4 has produced a new documentary that also appears to favour being controversial over being accurate or fair: What the Green Movement Got Wrong. Adam Werbach who was in the documentary protested that his views were misrepresented and tried to have his contribution removed.…

Andrew Bolt endorses Lancet study

Andrew Bolt accepts the results of a study published in The Lancet that used random sampling to estimate deaths and came up with a figure of 200,000 per year, about ten times the number you get from a direct count. Actually, there are two studies that fit my description, one on deaths from malaria in…

Indur Goklany, DDT and Malaria

Ed Darrell points to a WUWT post by Indur Goklany which promotes the use of DDT to fight malaria instead of more effective measures. As with most of the DDT promoters, Goklany carefully avoids mentioning the way mosquitoes evolve resistance to insecticides. For example, here’s what he has on Sri Lanka: For instance, malaria incidences…
