Ice over 128,000 years old found in Tibet could reshape climate history

Scientists studying ice cores drilled from Tibet's Guliya Plateau in 1992 and 2015 found ice that may be more than 128,000 years old, surviving since the last ice age. The discovery extends the region's known glacial record by over 100,000 years, making them the oldest cores from that part of Tibet and offering rare insight into Earth's ancient climate.
