Climate Change and the Forests of the West (Keeling Lecture)

The Keeling Lecture
Climate Change and the Forests of the West   
UCTV - Perspectives on Ocean Science

Uploaded on Jun 10, 2010
Dr. Steve Running, a Regents Professor in the College of Forestry and Conservation at the University of Montana, discusses the paradox of why forests in the West are growing faster while simultaneously suffering from higher die-off rates. 

Running was the IPCC lead author on a 2007 WG1 report analyzing North America's contribution to atmospheric carbon dioxide and its impacts on the global climate.
