China Ocean Development Report
China's sea level will rise by 30 millimeters in the next 10 years, predicted "China's Ocean Development Report 2009", released by the State Oceanic Administration on May 15..
The report indicated that the level of Bohai Sea will go up by 29 millimeters, Huanghai Sea by 31 millimeters, and East China Sea by 30 millimeters.
The rising of sea level is one of the reasons that has caused costal erosion and seawater intrusion. However, the report concluded that human activities such as sea sand mining, coastal engineering construction caused more severe costal erosion than the global climate change did the past 10 years.
China's sea level rises at an average speed of 2.5 millimeters a year, slightly higher than the world's average, according to the report.
"China's Sea Level Report 2007" also said the air temperature in China's costal area rose by 1.1 degree Centigrade, sea surface temperature 0.9 degree Centigrade, sea level 90 millimeters in the last 30 years. The sea level at Tianjin rises the fastest by 196 millimeters, and Shanghai ranked the next by 115 millimeters. The report also presented the pattern that the sea level rose more rapidly in the north than in the south.
The report is the second of its kind. State Oceanic Administration issued the first of the series annual report in 2008.
