In recent months, ABC reporter Bill Blakemore has been a passionate proponent for getting all that harmful objectivity and balance out of reporting on the impending disaster of global warming. So it shouldn't be surprising -- it should flow naturally, like a melting glacier -- that Blakemore is using ABC's World Newser blog to plug Al Gore's new documentary "An Inconvenient Truth." The filmmakers could use Blakemore's review here as a promotional blurb. He calls it "96 minutes well spent," says "Regardless of your politics, it's riveting and informative," not to mention "remarkably clear, concise, and informative."
