Exploratorium biologist Karen Kalumuck will examine how increasing temperatures affect specific organisms at the poles—from 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 biologist Charles Carlson talks about why climate change is causing a crisis with the Gulf Stream. More quick answers to the most frequently asked questions about global warming. Watch as Exploratorium physicists Paul Doherty and Stephanie Chasteen play around with the leading greenhouse gas: carbon dioxide. What is it? How much is there in our atmosphere? What does it do that is so harmful to the environment? Join Exploratorium staff Paul Doherty and Robyn Higdon as they discuss the Transit of Mercury. On November 8, 2006, Mercury slowly slid across the face of the sun during a relatively rare event known as a transit. The Exploratorium's Live@ crew was at the Kitt Peak National Observatory in Arizona to cover the event. This webcast includes a brief history of Kitt Peak and its 21 telescopes.
