Longest ice core extracted in Xizang

Chinese scientists announced on Tuesday that they have extracted the world's longest ice core in Earth's mid-to-low latitudes. The core was extracted in the Purog Kangri Glacier in Tsonyi county, Xizang autonomous region. Measuring 324 meters in length, the ice core surpasses the previous record held by a core extracted from the Guliya Ice Cap in Xizang's Ngari prefecture. The Purog Kangri Glacier is the thickest glacier on the Qinghai-Tibet Plateau. By delving into this icy expanse, researchers aim to gain valuable insights into the changing landscape of the region. Through meticulous examinations of ice cores, scientists hope to unravel the transformations occurring within the glacier and shed light on the impact of global climate change on glaciers worldwide. The milestone marks a crucial step forward in the efforts to understand the effects of warming temperatures on these vital natural formations.
