Join Senior Scientist Paul Doherty as shows how to melt ice unbelievably fast! Join Exploratorium staff as they give the quick answers to the most frequently asked questions about global warming: What is a "tipping point"? What are carbon credits? What is carbon neutral? What can I do? What can my kid do? Join us as we talk to scientists from the ANDRILL (ANtarctica DRILLing) project, who are currently on a geological drilling expedition in Antarctica. Join us as we talk with Robert Henson, author of The Rough Guide to Climate Change. Stephanie Chasteen speaks with Zan Stine, a graduate student in the Earth and Planetary Sciences Department at the University of California at Berkeley, at the annual American Geophysical Union meeting. Mr. Stine tells us about his search for the reasons why summer is coming earlier than it did in the past. Stephanie Chasteen speaks with Jerry Osborne of the University of Calgary about his work studying glaciers to understand how the climate is changing in recent years. Join us as we chat with Chris Mooney, Washington correspondent for Seed Magazine and author of Storm World: Hurricanes, Politics, and the Battle Over Global Warming and The Republican War on Science. His blog can be found at http://scienceblogs.com/intersection. Exploratorium Producer Mary Miller chats with Marika Holland, Climate Modeler for the National Center for Atmospheric Research. Dr. Holland co-authored a recent study projecting that the summer Arctic sea ice could completely disappear by 2040. Join Mary Miller in conversation with Mark Serreze, Senior Research Scientist at the National Snow and Ice Data Center, as they discuss recent dramatic decreases in Arctic sea ice and what that means for global climate stability. Tom Crawford and Jeff McMahon show us a day in the life of a South Pole scientist, then talk about what the telescope will be searching for: dark matter, galaxy clusters, and evidence of the universe expanding.
