What did the world look like millions of years ago? Was it swathed in forest, or did savannah grasslands stretch from pole to pole? What did it smell like? How hot was it? Could life survive there? What can past landscapes and climates, and the life that inhabited them, tell us about our future? Join Jennifer Mc Elwain, from Trinity College Dublin, on a journey through 400 million years of Earth’s landscape and climate history, and on an expedition to Greenland to collect some of the fossil plants that provide key evidence for these changes.
