Date: Wednesday, March 11, 2015
Time: 10:30 AM

Room: 0048 Scott Laboratory
Benson will present “tree-ring based reconstructions of precipitation” to ague that “megadroughts” caused these two great American Indian civilizations to collapse at nearly the same time.
The repercussions of the fall of Cahokia certainly would have been felt in Ohio. Indeed, when the population around Cahokia began a severe decline at around A.D. 1300 Mississippian cultural traits began appearing at Ohio sites, such as SunWatch Village. Perhaps this was a result of refugees from Cahokia moving eastward into the Ohio valley.
This should be a fascinating discussion on the role that climate change might play in the rise and fall of civilizations.
As the first president to speak on the radio, Warren G. Harding introduced Americans to the idea of being able to hear their leaders.
