On this episode, Nate is joined by Peter Brannen, science journalist and author specializing in Earth’s prior mass extinctions, to unpack our planet’s geologic history and what it can tell us about our current climate situation. Humans have become very good at uncovering the history of our planetary home - revealing distinct periods during billions of years of deep time that have disturbing similarities to our own present time. How is the carbon cycle the foundation of our biosphere - and how have changes to it in the past impacted life’s ability to thrive? On the scales of geologic time, how do humans compare to the other species who have inhabited this planet - 99% of which have gone extinct - and will we end up being just a blip in the fossil record? How can an understanding of geologic and climate science prepare us for the environmental challenges we’ll face in the coming decades?
