During an interview with the Competitive Enterprise Institute's Marlo Lewis, CNN's Heidi Collins did not challenge Lewis' assertion that, in An Inconvenient Truth, Al Gore claimed that global warming would cause sea levels to rise "20 feet ... in this century." Lewis added: "That is science fiction, but Gore presented it as fact. It's scaremongering." In fact, Gore was addressing what could happen if the West Antarctic ice shelf or the Greenland ice dome "broke up and slipped into the sea" at an indefinite point in the future, not "in this century."
MSNBC's Keith Olbermann named Fox News host Sean Hannity the "winner" of his nightly "Worst Person in the World" segment for defending musician and right-wing activist Ted Nugent after airing video footage of Nugent's smears of Democratic presidential candidates Sens. Barack Obama and Hillary Rodham Clinton. Olbermann also named Fox News' Brit Hume the "runner-up" for distorting recently published research on global warming.
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.
