The global cryosphere shrank by around 87,000 square kilometers per year on average during the 1979-2016 period as a result of global warming, showed the latest study by Lanzhou University.
The study highlights the importance of assessing the cryosphere as a whole, and provides a way to quantitatively estimate its overall changes, said Zhang Tingjun, a professor with the College of Earth and Environmental Sciences of Lanzhou University.
It also pioneers the world in making a comprehensive evaluation of the entire global cryosphere, according to Peng Xiaoqing, lead author of the study.

LANZHOU, April 19 (Xinhua) Chinese archaeologists are using the latest technology to understand the lives of an ancient ancestor of human beings, based on a jawbone fossil found on the Qinghai-Tibet Plateau.
By studying the fossil and sediments from the Baishiya Karst Cave in which the fossil was discovered, researchers have identified the jawbone as belonging to an extinct species of archaic human named Denisovan hominins that had previously only been found in Siberia.
In addition to extending the known range of the Denisovans, the discovery provides evidence of pre-historic human activity on the Qinghai-Tibet Plateau at least 160,000 years ago, much earlier than the previous date of 40,000 years ago.
