Geologist Dr. Iain Stewart explores how a single force like wind or vulcanism shapes our planet and impacts life, interacting with other natural elements and life forms, as in climate change.

In each episode, geologist Dr. Iain Stewart explains the effects and importance of a specific force of nature, such as wind or volcanism. He also examines the various ways in which it shapes planet earth itself and influences life on it, often in conjunction with other natural forces, and sometimes with lifeforms, as in the 'apocalyptically' grave case of global warming.—KGF Vissers
