Ocean Warming, sea-level rise and coastal flooding
China
The average rate of sea-level rise was 0.09 +/- 0.04 inches (2.3 +/- 0.9 mm) per year over the last 30 years. Global sea-level rise was aggravated locally by subsidence of up to 2 inches (5 cm) per year for some regions due to earthquakes and groundwater withdrawal. Also, ocean temperatures off the China coast have risen in the last 100 years, especially since the 1960s.
