BEIJING - A report released in Beijing Friday said there is no scientific evidence that the Three Gorges Dam has caused change to the climate and is to blame for meteorological disasters in recent years.

Research has shown that the radius around the dam within which environmental conditions have been impacted by the development is less than 20 km, said the report titled "Green Book of Climate Change: Annual Report on Actions to Address Climate Change (2011)", published by the Social Sciences Academic Press under the Chinese Academy of Social Sciences.

No direct link has been found between the dam and local severe droughts and floods in recent years, according to the report, which instead laid the blame on extreme weather conditions caused by abnormal atmospheric circulation and air temperature mainly incurred by changes in ocean temperature and snow conditions at the Qinghai-Tibet Plateau.

The report suggested the authorities strengthen monitoring, evaluation and research of the climate condition in regions around the dam.
