Professor's video series explains all facet...(has co-taught for more than 15 years at ...)

Wysession noted that several lectures are devoted to the theme of climate and humans, and how geological events have played vital roles in shaping human history. He sited the example of a huge volcanic eruption at Tambora in Indonesia that in 1816 filled the Earths skies with so much ash and aerosols that crops failed globally and the Earth was colder for many years. This timeframe corresponded to the westward migration of people from the eastern United States in search of suitable places to grow crops.

While Wysession is an old pro at delivering lectures, he said that lecturing in a classroom and making these types of studio-based video lectures are two very different ways of getting the message out to the public. And he had an adjustment to make.

He made the lectures at the Teaching Companys large studio in Chantilly, where he gave up to three lectures per daily studio session.

I was nervous at first, he said. I was in a room with lights and cameras but no people, and I had to look like I was relaxed and conversing with people. We had to re-do the first six lectures, but then I found my stride.

Its a real honor to do these for the public, and a pleasure to get the message out that the systems that control Earth, including people like you and me, are all interconnected.
