Today we breathe an atmosphere consisting of a blend of nitrogen, oxygen, carbon dioxide, argon and few other trace gases. While we rightly worry about carbon dioxide, methane and ozone concentrations we don’t often think about other gases in air like oxygen, nitrogen, and hydrogen but these too have a varied history. This talk by Dr Matthew Warke will explore how rocks record the evolution of Earth’s atmosphere over time with implications for climate, habitability and life.
