Melting glaciers raises sea levels in China. How cities are coping
China's seas reached high levels last year as a result of melting glaciers, says the Chinese government report.
The coastal level was 84 mm higher in 2021 than the average during the period from 1993 to 2011.
What is the impact of rising sea levels on Chinese cities?
Last year, the environment ministry predicted another 55 mm rise in coastal water levels over the next 30 years, which would require a greater effort by China to protect its coastline.
The long-term effects of such an increase include erosion of coastal ecosystems and loss of habitat from tides, while coastal towns face greater risks of floods and salt tides.
Shanghai is seeking the construction of new drainage tunnels and tidal gates.
Chinese cities on the east coast have begun making emergency plans against rising sea levels, with the Shanghai shopping mall requiring the construction of new drainage tunnels and tidal gates.
Projections such as those of the Intergovernmental Panel on Climate Change (IPCC) show that sea level rise is a "serious threat to China's coastal cities and population."
