ESCI 325 - Mass Extinctions

Semester Offered: Fall
1 unit(s)
It is often argued that our planet today is undergoing the “sixth mass extinction”. What defines a mass extinction in the rock record? What forces are able to cause such immense destruction of life on Earth? And, what are the outcomes of mass extinction for life on the planet? In this course we use the geologic record as our guide to understanding the consequences of asteroid impacts, rapid greenhouse gas emissions, and glaciation for the Earth System. We also explore ongoing controversies in the scientific literature regarding the cause of these catastrophic events. In group discussions, we probe the ways that the context of past mass extinctions can be used to inform conservation policy. Laura Haynes.
