Polar ice sheets are sensitive indicators of current climate and also preserve evidence of past climate conditions. Scientists studying Earth's climate history core thousands of meters deep into ancient ice to retrieve gas bubbles trapped in ice sheets. Ice cores help reconstruct climatic conditions from hundreds of thousands of years ago. Join Dr. Jeff Severinghaus as he explains how gas bubbles are trapped, how they provide detailed chemical clues to the past and how they are helping to shape future climate scenarios. (45 minutes)

In this Second Annual Keeling Lecture from Scripps Institution of Oceanography at UC San Diego, Lonnie G. Thompson, distinguished professor of earth sciences at Ohio State University and recipient of both the National Medal of Science and the Tyler Prize for Environmental Achievement, provides insight into the convincing evidence of climate change provided by glaciers and polar ice-caps, and the implications that inaction in the face of this rapid change will have on societies on a global scale.

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 is a member of the Nobel Peace Prize-winning Intergovernmental Panel on Climate Change and was the lead author on a 2007 report analyzing North AmericaŐs contribution to atmospheric carbon dioxide and its impacts on the global climate.

Carbon dioxide has been steadily increasing in the Earth's atmosphere since the industrial rEvolution. Join Dr. Tim Lueker as he describes the history of atmospheric carbon dioxide research and the role the ocean plays in global warming. Learn how Dr. Lueker and others gather data that allow them to assess these important changes in the state of our atmosphere and ocean. (54 minutes)
