Great course for the non-professional student- keeps the subject matter discussions light and contemporary. Especially loved the idea of ecological proxy, which I had never heard before!

The professor, plus the course syllabus, and the way in which they were both presented exceeded all my hopes and expectations for learning as a beginning geology student major.

An absolutely amazing course with an enthusiastic, engaging professor. I would give more stars if I could! I learned so much and was constantly excited for the next lesson.

I would have preferred less camera focus on the lecturer and more use of illustrations, charts, etc. It was a little boring just watching the lecturer talk.
