The Race to Save Glacier Ice Records

Planet Earth ·

2026/08/03

Glaciers are far more than just massive blocks of ice; they are Earth's natural ledgers, meticulously recording centuries of environmental history. High in the mountains, each annual layer of snowfall traps a time-stamped archive of dust, pollen, volcanic ash, and even tiny bubbles of ancient atmosphere. In this episode, we explore the "Memory of Water," from the 1950s discovery that a fizzing piece of ice in a glass of whisky could reveal the air of the past to the isotopic
