[3] The Purog Kangri ice field is at 33°51′18″N 89°48′18″E / 33.8550°N 89.8050°E / 33.8550; 89.8050 at an elevation of 6,072 metres (19,921 ft) above sea level.

[6] The Tibetan Plateau and Himalaya hold the largest amount of ice outside the Arctic and Antarctic.

Meltwater from the glaciers feeds the Yangtze, Yellow, Indus, Brahmaputra and Ganges rivers.

The upper 102 metres (335 ft) covered the last 1,000 years, and was analyzed along its length for the δ18O oxygen isotope ratio.

[8] The results, correlated and checked against ice cores from other locations, showed a sharp increase in temperature starting in the late 19th century.
