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. Join Exploratorium physicists Paul Doherty and Stephanie Chasteen as they examine the past, present, and future of climate change. In this show, Paul and Stephanie discuss the future of our climate. Learn more about the oceans, global warming, feedback effects, glacial ice and sea ice, and some things you can to do help. Exploratorium biologist Karen Kalumuck will examine how increasing temperatures affect specific organisms at the polesfrom phytoplankton to polar bears! Join Exploratorium biologist Karen Kalumuck as she experiments with enzymes and proteins and shows at what temperatures they function best. Join Exploratorium biologist Karen Kalumuck as she investigates the characteristics of living organisms and ecosystems, and how climate change affects them. South Pole scientists Tom Crawford and Jeff McMahon take us on a virtual tour of the South Pole Station, then discuss working in the polar environment. Join Exploratorium physicists Paul Doherty and Stephanie Chasteen as they examine the past, present, and future of climate change. Watch as Paul and Stephanie demonstrate how you can look at a slice of climate from the past, what a sediment core might look like, and the secrets hidden in an ice balloon! Exploratorium physicist Paul Doherty chats with Richard Levy, a geologist, and Ross Powell, whos the co-director of the ANDRILL project. They are drilling beneath the Antarctic seafloor, and pulling up sediment cores. By looking at the layers of the past, they hope to help us predict our future.
