Brokaw Joins Fight Against Global Warming

Tom Brokaw is giving Al Gore some company in the effort to raise awareness of global warming. The former NBC anchorman is host of “Global Warming: What You Need to Know,” which doubles as an explainer and call to action for average Americans. It premieres Sunday at 9 p.m. on the Discovery Channel.

Brokaw said he has seen and was impressed by “An Inconvenient Truth,” Gore’s documentary on the subject.
