BROOKINGS - A professor at South Dakota State University is looking at ice from Antarctica to better understand climate change.

Professor Jihong Cole-Dai of the chemistry and biochemistry department and graduate student Kari Peterson spent nearly a month in Antarctica during Christmas break as part of a project to obtain a slice of ice from 17,500 years ago. The ice will help scientists figure out how Earth came out of the Ice Age and how climate change can happen in the future.

The National Science Foundation funded the project, which started eight years ago. It involves more than 20 universities and national laboratories.

Each university will get its slice of the ice to be able to analyze it. Cole-Dai says the analysis will take about a year.
