Fox News' Brit Hume cited "new research by University of Washington mathematicians [that] shows a correlation between high solar activity and periods of global warming" as evidence to support his claim that "[global warming] skeptics are increasingly certain that the scare is vastly overblown." But an August 9 New Scientist article on the mathematicians' research warned that "[c]limate-change skeptics may seize on the findings as evidence that the sun's variability can explain global warming -- but [the report's co-author] mathematician Ka-Kit Tung says quite the contrary is true." The New Scientist reported that Tung says his finding, in the New Scientist's words, "adds to the evidence that mainstream climate models are right about the likely extent of future human-generated warming."
On Special Report, Jim Angle reported that NASA was forced "to admit it was wrong when it said that 1998 was the hottest year on record" and that NASA "now says 1934 was the hottest year, followed by 1998, then 1921." But Angle did not inform viewers that NASA's revision affected annual temperature rankings for the United States only; it had no effect on the annual global temperature rankings.
In a Washington Post op-ed, Slate.com contributing writer Emily Yoffe wrote that Al Gore "and others say that [Hurricane] Katrina was a product of global warming." In fact, in An Inconvenient Truth, Gore does not claim that Katrina was a "product" of global warming. Additionally, Gore gave a speech two weeks after Katrina in which he said that "no single hurricane can be blamed on global warming."
On Lou Dobbs Tonight, Lou Dobbs again tried to downplay his program's airing and affirming of a falsehood about the number of leprosy cases in the United States. Dobbs also claimed again that his airing of a May 16 report by CNN correspondent Bill Tucker "set the record straight" on the leprosy issue, but the report did not note the uncritical citation of the false statistic or Dobbs' repeated defense of it.
On Special Report, Brit Hume cited a column asserting that "a majority of astrophysicists and other solar scientists may in fact disagree with the conventional wisdom" on global warming and said that the author, Lawrence Solomon, "points out that almost 18,000 scientists signed a petition in opposition to the Kyoto Protocol." But the petition to which Hume and Solomon apparently referred has been disavowed by the National Academy of Sciences, and many of the signatures on the petition apparently belong to people who are not climate scientists.
