REAL SPORTS WITH BRYANT GUMBEL
HBO, 10:00 p.m. ET
From tonight’s new edition, two examples of how far afield this series goes in pursuit of its engrossing sports stories: One is a profile of Chechan leader and MMA figure Ramzan Kadyrov, and the other is an examination of global warming, a.k.a. climate change, on Australia’s Great Barrier Reef, beloved by divers and other aquatic sports enthusiasts.
