Tubegazing: 'Six Degrees Could Change the World'

'Six Degrees Could Change the World,' presented by National Geographic, looks at the impact global warming could have on the world's most fragile – and remote – locales.

from the February 8, 2008 edition

(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+
