China says coastal sea levels hit new high in 2022
SINGAPORE — China’s coastal sea levels hit their highest on record in 2022, and have increased by an average of 3.5 millimeters (0.14 inch) per year since they were first measured in 1980, a government official said Wednesday.
Coastal sea levels last year were 94 millimeters higher than the 1993-2011 average, and have been rising more quickly than the global rate, said Wang Hua, head of the marine forecasting and monitoring section at China’s Ministry of Natural Resources.
“In the last 11 years, 2012 to 2022, China’s coastal sea levels were the highest since observations were first recorded,” he said at a press briefing.
Wang did not provide any comparative figures, but the 94-mm increase in average sea levels last year was 10 mm higher than 2021.
In an annual report published last May, China blamed the faster-than-average rise in sea levels on higher water temperatures as well as the melting of glaciers and polar icecaps.
