SAVANNAH — A vast storehouse of carbon, frozen in the Arctic permafrost for millennia, may play a role in future global climate change.

University of Georgia Skidaway Institute of Oceanography professor Aron Stubbins will discuss his research into this evolving issue in an Evening @ Skidaway program Tuesday. The program will be presented in the McGowan Library at the UGA Skidaway Institute, beginning with a reception at 6:30 p.m., followed by the lecture at 7:15.

While climatologists are watching carbon dioxide levels in the atmosphere, Stubbins is one of a group of scientists exploring how ancient carbon, locked away for thousands of years, is now being transformed into carbon dioxide and released into the atmosphere. Stubbins will describe his research, which has taken him from Skidaway Island to the Siberian tundra.

An Evening @ Skidaway is sponsored by the UGA Skidaway Institute of Oceanography and the Associates of Skidaway Institute. The program is free and open to the public. Space is limited. To reserve a seat, please call 912-598-2325 or email mike.sullivan@skio.uga.edu.
