China sees glaciers recede by 26% over six decades

China has lost 26% of its glacier area since 1960 due to accelerating global warming, with around 7,000 small glaciers vanishing entirely and glacial retreat intensifying, according to official data released in March.

Globally, glaciers are shrinking at unprecedented rates, with a Unesco report warning that the world has witnessed the largest loss of glacial mass on record in the past three years.

As the important water towers continue to shrink, less availability of freshwater is expected to contribute to greater competition for water resources, environmental groups have warned. Glacier retreat also poses new disaster risks.

China's glaciers are located mainly in the west and north of the country, in the regions of Tibet and Xinjiang, and the provinces of Sichuan, Yunnan, Gansu and Qinghai.

Data published on March 21 on the website of the Northwest Institute of Eco-Environment and Resources of the Chinese Academy of Sciences showed that China's total glacier area was around 46,000 square kilometres, with around 69,000 glaciers in 2020.

This compares to around 59,000 square kilometres and around 46,000 glaciers in China between 1960 and 1980, the study showed.

To save its melting glaciers, China has used technology, including snow blankets and artificial snow systems, to delay the melting process.

The Tibetan plateau is known as the world's Third Pole for the amount of ice long locked in the high-altitude wilderness.

The dramatic ice loss, from the Arctic to the Alps, from South America to the Tibetan Plateau, is expected to accelerate as climate change, caused by the burning of fossil fuels, pushes global temperatures higher.

This would likely exacerbate economic, environmental and social problems across the world as sea levels rise and these key water sources dwindle, the Unesco report said.
