The research, based on data from 38 weather stations
of the Tibet Autonomous Regional Meteorological Bureau, indicated that the
average temperature in the landlocked region rose 0.32 degree Celsius every 10
years between 1961 to 2008, according to Du Jun, a senior engineer with the

warming, he said, which triggered snow melting, glacial shrinking and rising
He said that other phenomena included grassland
degradation, more plant diseases and insect pests, a reduction in bio-diversity
and higher risks of disasters.
