Global warming threatens Tibet rail link

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.
