Global warming bringing negative effects on China - People’s Daily Online
The Global Climate Conference held in Durban of South Africa not long ago has made the world pay high attention to the climate change once again.
According to data offered by the China Meteorological Administration (CMA), China’s average temperature rise was higher than that of the world in the past 100 years. According to global surface temperature data, the global temperature rose by 0.47 degrees Celsius from 1906 to 2005. The temperature rising speed of the Northern Hemisphere was between 0.234 degrees Celsius and 0.245 degrees Celsius per decade in the period between 1979 and 2005, higher than that (between 0.092 degrees Celsius and 0.096 degrees Celsius) of the Southern Hemisphere.
The abnormal climate change of China is reflected in not only the rise of the annual mean temperature but also the direct and indirect effects brought by it. The vice director general of the Technology and Climate Change Department under the CMA Chao Qingchen said that, compared to 1880, China’s precipitation has not changed much, but a decade-long fluctuation occurred in a period between 20 and 30 years. The solar radiation on the land surface has decreased. Compared to 1960s, both the winter and summer monsoons of the East Asia have weakened. In the 1990s, 82 percent of glaciers were shrinking and the shrinking speed has been accelerating since then. Since 1950s, China’s sea level is rising 2.5mm per year.
