Tibetan Plateau ice-core record indicates Guliya ice cap is over 100,000 years old

Science Advances says researchers constructed the oldest ice-core-derived climate record from the Tibetan Plateau.

The Guliya ice cap (GIC) is the largest body of ice in the western Kunlun Mountains in the Tibetan Plateau. Ice cores drilled on the GIC preserve the record of past climate change in the region, an area which provides water for several billion people in Central and South Asia. Thompson et al. analyzed ice cores drilled in 1992 and 2015 and used cosmogenic isotopes and Asian monsoon records to construct an accurate climate timescale extending back 128,000 years, the oldest ice-core-derived climate record from the Tibetan Plateau. The timeline supports the presence of glacial-stage ice in the GIC, confirming that GIC ice is over 100,000 years old.
