Global Warning DVD
Is "global warming" fact or fiction? Are melting ice caps and rising sea levels attributable to human activities, or are they naturally occurring cycles of the Earth's ongoing evolution? Or, is the inconvenient truth that the planet's changing climate is both natural and manmade? This History Channel documentary explores the science and speculation surrounding one of the 21st century's most divisive controversies. 100 min. Soundtrack: English; bonus footage.
