For the past 100 years, the sea level has risen by 6 inches (14.4cm) and in China it has increased by 5 inches (11.5cm). The reason for the rise in sea level is the thermal expansion of seawater. With the warming of the ocean, icebergs are melting in the north and south poles of the Earth. The direct impact of sea level rise has the following aspects:
Lowland flooding: Britain’s Sky Rafts Deal with Climate Warming: Global warming also increases the intensity and the frequency of storms. In Britain, the high sea levels are preventing them from raising the flood control embankment. According to statistics released by the British government, for the past 20 years, the Thames River has increased due to global warming. In order to protect the safety and property of its residents, Local government agencies had to raise the flood protection embankment 88 times. Reports state on average the dikes are raised four times a year. It is estimated that before 2030, the use of its levees will reach 30 times a year.
Tourism: In China, their tourism industry is in jeopardy because the sea level has risen by 50 meters. Coastal tourism areas like Dalian, Qinhuangdao, Qingdao, Beihai, and Sanya have been back 31-366, with 24% loss on the beach and 60% loss on Beidaihe beach. In a 2002 China Land and Resources Bulletin report, coastal tourism has become the largest industry with a production value of 250.3 billion yuan, accounting for 34.6% of the total value of the marine industry.
Economics: Rising sea levels threaten the lives of coastal and island country residents that accounts for one-third of the world’s population. If the polar ice cap melts, the economically developed and densely populated coastal areas will be destroyed by the sea. Low-lying island areas such as the Maldives and Seychelles will disappear, so will other coastal cities like Shanghai, Venice, Hong Kong, Rio de Janeiro, Tokyo, Bangkok, New York. Countries like Bangladesh, the Netherlands, and Egypt will also be unable to escape. The impact of climate change will affect us all.
