Global warming is tapping the cultural zeit geist, with 2006 on track to smash an all-time record for news attention (more on this soon), and various film and TV events trying to raise public attention to the issue. The latest, reports the Washington Post today, is a Discovery Channel documentary slated for 9pm Sunday night, hosted by Tom Brokaw. And if Inconvenient Truth is setting records in terms of revenue for a science film, stay tuned for the fall, when Leonardo DiCaprio releases his 11th Hour documentary on the environment.
