Vanishing Alpine glacier reveals 2,000 years of fires, mining and eruptions

A remarkable ice core from the Alps has revealed a comprehensive climate timeline spanning 2,000 years. It documents early instances of metal smelting, extensive forest fires, and even volcanic ash from distant eruptions. This icy archive acts as a vital record of air quality in Europe before industrial contaminants took hold. As glaciers retreat, scientists are in a race against time to safeguard these precious climate memories for future generations.
