Qinghai-Tibet Plateau research offers insight into effects of climate change

Editor's note: As protection of the planet's flora, fauna and resources becomes increasingly important, China Daily is publishing a series of stories to illustrate the country's commitment to safeguarding the natural world.

Having roamed the wilderness in Shanza county on the northern hinterland of the Qinghai-Tibet Plateau for more than 15 years, Tsultrim Tharchen, a wildlife ranger, can see with ease the distinct changes brought by warming temperatures.

"The pasture grass grows significantly taller now than before, and I'd never seen so many wildflowers in the past," he said, pointing to clusters of tiny, jewel-like blossoms in purple, yellow and white dotting the steppe.

Situated at an average altitude of 4,700 meters, the county used to be inundated by harsh winds, making a motorcycle ride in winter punishingly cold for Tsultrim Tharchen. "Nowadays, winter feels not so hard to get through," he added.

The observations of Tsultrim Tharchen encapsulate the very basics of climate change on "the roof of the world". The geologic expanse defined by majestic mountains, pristine lakes and long, dry and frigid winters is getting warmer and wetter.

While local residents like Tsultrim Tharchen rely on their senses to take the pulse of the plateau, a group of Chinese researchers has utilized scientific equipment and multidisciplinary expertise to survey the land's response to climate change.
