摘要

Within the bustling campus of Ohio State University (Columbus, OH) rests one of the most extensive archives of the Earth's history chronicling the past 700,000 years. Visually, this repository may not appear impressive: no fossils or pottery fragments, just ice—lots and lots of ice. Over 7,000 m (≈ 4.2 miles) of glacial ice, to be exact, have been collected from some of the most imposing mountaintops of the world: the Andes, the Himalayas, even the snows of Mount Kilimanjaro. Trapped and preserved within these frozen cylindrical cores, however, lies the true beauty of these specimens: small flecks of dust and oxygen isotopes that provide a historical record of trends and shifts in the earth's climate.
