Tubegazing: 'Six Degrees Could Change the World'
(National Geographic Channel, Feb. 10, 8 p.m.): This 96-minute film, narrated by actor Alec Baldwin, tackles global warming as only National Geographic could – with a brilliantly colored travelogue of the possible impact on some of the world's most remote and fragile locales, from the pristine headwaters of the Ganges River, high in the Himalayas, to the tiny villages of Greenland. Heavy on alarmist scenarios as it is, with only a smattering of solutions tucked in, this is nonetheless a ravishing portrait of a planet heading toward peril. Grade: B+
