Global warming threatens Tibet rail link
BEIJING, Feb 5 (Reuters) -Global warming could threaten the new Qinghai-Tibet Railway, the world's highest, within a decade, a Chinese researcher said in remarks published on Sunday.
Wu Ziwang, a frozen soil specialist at the Chinese Academy of Sciences, told the official Xinhua news agency his research over three decades revealed large areas of the Qinghai-Tibet plateau showed signs of shrinking, as they were frozen less of the time.
This could threaten the new railway, which is to start operations this year, Wu said.
"Fast thawing of frozen soil in the plateau might greatly increase the instability of the ground, causing more grave geological problems in the frozen soil areas where major projects such as highways or railways run through," Wu added.
A separate report by the academy's desert institute showed that temperatures on the plateau have been rising markedly since 1984 and that winter temperatures could rise by another 1-2 degrees Celsius by 2050.
China completed construction of the controversial pan-Himalayan railway in October. It is to go into trial operation on July 1, Xinhua said.
