When Earth Breathed Deeply
Earth's climate has not been constant throughout history. Oxygen levels in the atmosphere, for example, have increased by many orders of magnitude over time, profoundly affecting biologic and chemical cycles at the surface of the earth.These changes in Earth's climate can be traced through the imprints left behind inside the planet. In this lecture, Bucholz will explore how such shifts in atmospheric oxygen concentrations altered Earth's inner workings.
