Expeditions with Patrick McMillan: California's White Mountains

Expeditions with Patrick McMillan: California's White Mountains - Ancient History and the Future
Air Date: April 13, 2008

I can think of no better place to see the changes of the past and those happening today than the deserts of California. Packrat middens, Creosote Bush and Joshua Trees have told us a story of a warming and drying climate and a precarious future. We're here in the White Mountains to visit with the ancients-trees that have survived over 4,000 years and are a living historical record of past climate and perhaps trends for the future. From the adorable pika to pinyon jays life as we know it is changing here. The oldest living things on earth are standing on the front lines of the climate change battle and trees that have stood for 40 centuries may not see the end of the 21st.
