Ancient air survives inside Antarctic ice cores. Antarctic climate scientist Dr. Tas van Ommen explains how compacted layers of snow preserve atmospheric gases, dust, volcanic sulphur, and water isotopes, creating a continuous climate record reaching back about 800,000 years. Hear what it takes to drill ice cores kilometres below the Antarctic surface, why researchers are searching for a continuous million-year ice core, and how ancient air bubbles help test modern climate models. The episode also reveals how an Antarctic snowfall record helped researchers understand long-term drought and rainfall changes in Western Australia.
