Expeditions with Patrick McMillan: California Deserts

Expeditions with Patrick McMillan: California Deserts - Coping with Climate Change
Air Date: April 6, 2008
Deserts may seem to be barren wastelands, but they're teeming with life. Deserts provide us with some of the best evidence of past climate change. Life has adapted to the harshest extremes of climate - but even these hardy sentinels can be pushed over the limit. Join Patrick as he explores the deserts of Joshua Tree National Park to see how these creatures can survive and gather evidence of past climates and dramatic changes happening right now.
