When did the first deep Antarctic ice core reveal past climate history?
Earth scienceClimate
Quick Answer
In the 1960s, when early deep ice cores from Antarctica began preserving trapped ancient air and temperature clues.
The Full Story
Deep ice-core science began to transform climate research in the 1960s, when Antarctic drilling revealed layered ice containing trapped air bubbles. These cores provided direct evidence of past atmospheric composition and temperature changes. Later, much deeper projects such as the Vostok core greatly extended the record, but the 1960s marked the start of the field. Ice cores became one of the most important archives for studying Earth’s climate history.
