Tibetan ice core extends climate record by 128,000 years

An ancient ice core from the Tibetan plateau has extended Earth's climate record by 128,000 years, offering a rare and validated glimpse into the last ice age. This discovery preserves climate indicators that scientists had believed were lost, reshaping our understanding of how glaciers survive dramatic global shifts. The findings connect directly to the urgency of measuring change, much like the accelerating glacier loss detailed in Switzerland's recent five-year study. Understanding drives protection, from the highest peaks to the deepest ocean.
