 Rising sea level is an alarming trend because China has a very long and densely populated coastline, with some of the most economically developed cities such as Shanghai, Tianjin, and Guangzhou situated there.Chinese research has estimated that a one-meter rise in sea level would inundate 92,000 square kilometers of China's coast, thereby displacing 67 million people.There has also been an increased occurrence of climate-related disasters such as drought and flood, and the amplitude is growing.
