Tibetan Plateau: worst-affected by global climatic changes

The Tibetan Plateau has posted the world's highest temperature rise, with an average increase of 0.3 degree Centigrade every decade since the 1990s, according to a Chinese scientific report.

"In the past decade, obvious changes have taken place on the plateau, especially the increasingly higher water level and larger surface of several lakes," said Zhong Xianghao, 70, who led a 30-member team in conducting annual environmental surveys on the plateau at an average altitude of 4,700 m for two months.

His team has worked out a blueprint for the plateau's eco-construction for the first time following tens years of efforts.

"The rise in the water level has resulted partly from the higher rainfall and the faster melting of glaciers and frozen soils," Zhong added.

Yet, the impact of human activities on the plateau is moderate on the whole, and the global climatic changes have posed a more serious threat to the plateau's eco-environment, Zhong noted.

"The plants there always struggle for survival in most of the year, except the growing period from June to August," Zhong said.

"With a fragile eco-environment, eco-variation and other eco-problems will be more likely to crop up on the plateau than elsewhere. As a result, damages and potential losses such as the extinction of rare species will be more serious," Zhong said.
