The abnormal climate results from a variety of reasons. However, it is mainly attributable to the global greenhouse effect, experts noted. With an underdeveloped industry, Tibet has taken strict measures to protect its environment, which is almost immaculate, said Purpu Zhoima. The deterioration of the ozone layer over the region has also contributed to these changes, experts said. Research shows the ozone layer over Tibet has been seriously depleted, causing the air temperature to rise sharply.
Some places begin to suffer heavy floods and snowfalls while enjoying more trees and more oxygen.
Last August, a rarely-seen flood took place in the Nyangqu River valley in Tibet. The rise of the snow line, melting of glaciers and frequent mud avalanches reported in Tibet have also raised experts' concerns. The Tibetan administrative organs have begun to take into account the climate changes when framing the local social and economic development program, sources said. So far, how the abnormal climate in Tibet will influence the global climate is still unclear, experts said. The climate in Tibet has drawn wide attention from scientists worldwide, he added.
