TED: Inside an Antarctic time machine | Lee Hotz

The video explores Antarctica's unique climate and its role in understanding climate change. Researchers at WAIS Divide drill ice cores to study historical climate data, focusing on greenhouse gases and temperature changes. The process involves extracting and analyzing ice cores, which serve as time capsules of ancient air. Despite challenges, this research is crucial for understanding climate impacts and guiding future environmental efforts.
