On the June 7 broadcast of his nationally syndicated radio program, CNN Headline News host Glenn Beck became the latest critic to compare An Inconvenient Truth, a documentary film about former Vice President Al Gore's campaign to raise awareness of global warming, to the Nazis. Beck dismissed many of the conclusions drawn from the documentary, stating, "[W]hen you take a little bit of truth and then you mix it with untruth, or your theory, that's where you get people to believe. ... It's like Hitler. Hitler said a little bit of truth, and then he mixed in 'and it's the Jews' fault.' That's where things get a little troublesome, and that's exactly what's happening" in An Inconvenient Truth.

As Media Matters for America has previously noted, Sterling Burnett, senior fellow at the National Center for Policy Analysis, called the film “propaganda” and added: “You don't go see Joseph Goebbels' films to see the truth about Nazi Germany. You don't want to go see Al Gore's film to see the truth about global warming.”

From the June 7 broadcast of The Glenn Beck Program:

BECK: So, if you look at this chart, you will see the CO₂, and it mirrors the temperature. Now, what I find interesting about this chart is CO₂ seems to naturally go up by itself. Hmmm, I don't remember those 200,000-year-old cars; I think Henry Ford wasn't around yet. I don't know if Fred Flintstone actually did have a car, but apparently, according to this chart, somebody was driving around in a car or an airplane. Maybe it was Al Gore giving the frickin speech at Stone Age colleges. I'm not sure, but it definitely correlates.

Now, what happened where this thing falls apart -- and it won't for most people who go to this movie -- is he then projects what's coming. Again, it's the projection that's the problem. See, when you take a little bit of truth and then you mix it with untruth, or your theory, that's where you get people to believe. You know? It's like Hitler. Hitler said a little bit of truth, and then he mixed in “and it's the Jews' fault.” That's where things get a little troublesome, and that's exactly what's happening. Now, if Al Gore's projection is right about the CO₂ level going as high as he says it will, then the temperature here on planet Earth will be about 400,000 degrees. We'll be the sun; we'll be the frickin sun. But that's a huge “if.”
