Episode 2 Asking Questions

Geological time boggles the brain. Millions of years in the past the Earth looked very different than it does today. But the past is in the past, right, why dig it up? Well it might help for the pickle we seem to be getting ourselves in to. We can't run whole Earth climate experiments but we can look back at previous ones to ask questions about what might be to come. Scientists Debbie Thomas and Laura Haynes explain to Claire why Expedition 378 is focusing on the climate during the Paleogene period.
