On Climate Change, Glaciers, and the Rock Record

Paul Hoffman (Department of Earth and Planetary Sciences, Harvard University) is one of the best orators I’ve seen. When I saw this talk by Paul Hoffman at McGill last year I was completely blown away. Not by the science, but by his skill as a story-teller. Paul Hoffman didn’t just tell us why we know the climate is changing, he told us the history of how we got to where we are today in our understanding of climate and Earth’s history. He started with the history of our understanding of glaciers, through the development of the “Snowball Earth” hypothesis, and the importance of the geologic record in climate science.

The talk is about an hour long and well worth it. Find it at the link below.
