Frozen vault preserves glaciers’ climate record

Deep beneath Antarctica’s snow, a natural ice vault is preserving priceless climate records that could help future generations understand a rapidly warming planet.

Deep beneath Antarcti­ca’s snow near Conco­rdia Research Station, scientists are preserving ancient ice cores from some of the world’s fastest-disappearing glaciers in a natural vault carved into compacted snow, CNN reported.

The project, led by the Ice Memory Foundation, aims to protect climate records locked inside the ice before rising global temperatures destroy them. The cores contain microscopic air bubbles that preserve evidence of past atmospheric conditions, volcanic eruptions, wildfire smoke and pollution stretching back centuries, and in some cases, millennia. Foundation president Tho­mas Stocker said the archive would safeguard environme­n­tal information for future generations, even if the glaciers themselves cannot be saved. 

Stored at a constant -52°C, the vault requires no artificial refrigeration. Scientists have already collected cores from 10 glaciers, including those in the Alps, Andes and Pamir Mountains. Researchers say the preserved samples could help future scientists study climate change using technologies yet to be developed, as glaciers worldwide continue to retreat at an accelerating pace and irreplaceable climate records disappear.
