The average area of glaciers ( 冰川 ) in Western China might shrink by about 30 percent by 2050 because of global warming,damaging crop production and worsening droughts.This dire prediction came Friday in a report released at the UN climate talks in north China' s Tianjin Municipality.The " Climate Changes and Poverty---Case Study in China" report was jointly released by organizations including the Institute of Environment and Social and Sustainable Development in Agriculture with the Chinese Academy of Agricultural Sciences.Forecasts of glacier recession ( 衰退) patterns showed the average glacier area in western China might be reduced by 27.2 percent by 2050,said the report.World ocean glaciers,affected by wet airflow from the ocean,would shrink by 52.5 percent,and Asian continental glaciers,formed in the continental climate would shrink by 24.4 percent.The report warned that global warming would reduce the seasonal snowfall period while melting area would be higher,contributing to the sharp decline.Moreover,climate change would not relieve water shortages ,but reduce river run-off by 20 to 40 percent in northwest China.Glacier shrinkage would also threaten China' s agriculture sector.' The report warned that overall crop production capacity would drop by 5 percent to 10 percent by 2030 due to global warming,especially in wheat,rice and corn,and the impact would worsen after 2050.
The Chinese government had attached importance to tackling the problems caused by climate change and taken effective measures to reduce the negative impacts,said Sun Cuihua,an official with the National Development and Reform Commission (NDRC) ,Friday at the climate talks.After three rounds of talks this year,which are moving slowly towards a negotiating text for the Cancun meeting in Mexico at the end of the year,more than 3,000 delegates from 194 nations gathered in Tianjin from October 4 to 9 to accelerate the search for common ground.However,the gap remains wide between the -developed and developing nations as the former remain cautious of green technology transfers and additional financing to poorer nations.
