A March 1 NewsBusters post by Noel Sheppard misrepresented an anti-global warming theory as mainstream when, in fact, it's merely one man's idea.
In what he called an "absolutely startling report about climate change," Sheppard cited a National Geographic News report on a claim by Russian scientist Habibullo Abdussamatov that global warming on Earth is being caused by changes in the sun, not by man. While Sheppard did excerpt a segment of the article calling it "one scientist's controversial theory," he went on to state, without offering evidence, that "To be sure, Abdussamatov is not the first scientist to make this claim."
However, Sheppard was vague in describing the criticism of the theory in the article:
Yet, in an article about a somewhat contrary concept as far as the mainstream media are concerned, National Geographic expressed great skepticism. In a piece that debunked what the supposed consensus believes on this issue, the magazine spent almost the bulk of the space alloted citing scientists that don’t buy Abdussamatov’s conclusions starting with, “Abdussamatov's work, however, has not been well received by other climate scientists.”
But Sheppard did not detail the specific criticisms of Abdussamatov's theory contained in the article. Chief among them: Not only does Abdussamatov apparently fail to take into account changes in Mar's orbit and tilt that would affect changes in Mars' climate, the article adds: "Perhaps the biggest stumbling block in Abdussamatov's theory is his dismissal of the greenhouse effect, in which atmospheric gases such as carbon dioxide help keep heat trapped near the planet's surface."
Oops! This is the guy who "debunked" the scientific consensus on global warming, as far as Sheppard is concerned? Perhaps Sheppard needs to stop copying-and-pasting articles and start reading them.
