Atmospheric chemistry that is captured in ice cores offer scientists a unique opportunity to uncover how climate and environmental conditions on Earth have changed over time.  In addition, ice cores can be used to  access the impact of human activities on atmospheric composition (natural vs. anthropogenic chemistry).
