Zooarchaeological studies seek to determine, among other things, what species of creatures the people who lived at a particular archaeological site ate and used. How important were migratory waterfowl in the diet of prehistoric peoples living in what is now the state of Georgia?

Undisturbed archaeological sediments and remains include invisible chemical and physical clues to the past. Scientists studying ice cores from Antarctica and Greenland have analyzed the oxygen isotopes in small air bubbles contained in ice cores from ice that was formed thousands of years ago. They have found that the Earth underwent abrupt climate change between 14,700 and 14,500 years ago.

This week our federal government released a report on global climate change that says in part, “Likely future changes for the United States and surrounding coastal waters include more intense hurricanes with related increases in wind, rain, and storm surges (but not necessarily an increase in the number of these storms that make landfall), as well as drier conditions in the Southwest and Caribbean.” These changes will affect Georgia’s archaeological heritage.
