What's a normal climate cycle? How do earth systems -- the shape of Earth's orbit, its tilt and wobble, as well as solar heating -- contribute to changes in Antarctica's ice? Why do ANDRILL scientists and climate modelers worry about warming? Using animation and climate models, see how ANDRILL tracks changes in Antarctica's environment through time. Examine a warmer Antarctica with higher greenhouse gases to learn where global climate is heading. For more of Antarctica's Secrets, including teachers' guides, visit http://www.netnebraska.org/ice.
