Class 13 (02/21/2018): Knowing the Hazards: Extinction

Class slides


There have been at least five times in Earth's history when a large number of species, on the order of 70-96% of all species, were lost over a relatively short period ranging from several ten thousand to several hundred thousand of years. These mass extinction events are attributed to periods of prolonged volcanic eruptions, asteroid impacts and changes in the state and chemistry of the planet. The current extinction rate is extremely high and leading to an unparalleled rapid loss of biodiversity.
