Christina, a geologist from Stanford University, investigates climate history by scouring sediment samples for diatoms, microscopic marine creatures that lived long ago in Antarctica's McMurdo Sound. Nadine, a glaciology graduate student from UC Santa Cruz, spent four weeks on the West Antarctic Ice Sheet investigating ice sheets and global climate change. Dr. Tulaczyk, a glaciologist from UC Santa Cruz, studies the lakes, floods, and ice quakes that occur under the giant glaciers of Antarctica. He is among only 200 scientists world-wide who study ice sheet dynamics and its role in climate change. Pulling food to prepare for four weeks at the West Antarctic Ice Sheet camp. Shots of the Barrow Environmental Observatory in Barrow, Alaska. Interview with Paolo Paulo Olivas about his research at the Barrow Environmental Observatory (BEO). Paulo Olivas points out the different equipment he uses to measure the amount of greenhouse gases being released from the tundra. The Jakobshavn Isbrae is among the fastest-moving glaciers in the world. The Jakobshavn is an outlet glacier, one of the few places where the giant Greenland ice sheet can shed ice in the form of gigantic icebergs. This timelapse video by Jason Amundson of the University of Alaska Fairbanks shows one of these massive calving events. Notice the dark blue ice that surfaces when the iceberg flips over in the ice-choked Ilulissat icefjord. Join host Mary Miller and Dr. Mickey Glantz in a discussion on issues around climate change and how it may affect communities. Dr. Stephen H. Schneider joins us to discuss climate change. Dr. Schneider was honored in 1992 with a MacArthur Fellowship for his ability to integrate and interpret the results of global climate research through public lectures, seminars, classroom teaching, and research collaboration with colleagues.
