The research of global sea level change of the last 10 years has been comprehensively reviewed and the main results of it have been obtained:(1) the global sea level rising ratios was around 2.5 mm/a to 3.84 mm/a, and the main contribution is from the thermal expansion of sea water; (2) there were some space differences for sea level rise, and the value in the West Pacific Ocean and the East Indian Ocean was especially more 10 times higher than the global average; (3) the seasonal fluctuation of sea level was obvious in areas of the Pacific Ocean and the Atlantic Ocean with north latitude 30-40 degree. When  the season of the highest sea level was compared with the term of the typhoon and hurricane occurring annually, it could be found  that there were global dangerous seacoasts, which were vulnerable by sea level rise, located in the regions of the Northwest Pacific Ocean and the North Atlantic Ocean with north latitude 20-50 degree during the seasons of Typhoon in August and October. The region includes coast areas as Chinese Mainland East Seacoast, Japanese Seacoast, American East Seacoast, Mexico Bay Seacoast and Caribbean Seacoast.
