To many Californians, the Sierra Nevada is a special, even sacred place. The segment notes that it helped inspire the American preservation movement. Today, millions of people flock to its national parks. But as humans alter the world's atmosphere, changes are afoot in Sierra parks. KPCC's Ilsa Setziol hiked to treeline in Yosemite to bring us the second report in our series on global warming in California. The delicate ecosystem that is being affected by climate change is discussed, specifically focusing on the relationship between birds and trees.
