摘要: 全球气候变化与海平面上升是人类面临的史无前例的挑战。全球气候将继续变暖,全球理论海平面今后100-200年将不会有大幅度上升,下一世纪上升幅度估计50-100cm。相对海面上升对人类威胁最大,因此许多国家制定对策,以抗御或减轻全球变化将造成的灾害。

Abstract: Global climatic warming and sealevel rise are the most serious challenge to mankind,Global warming will continue and is irreversible.Since Antarctica ice sheet will not melt and disintegrate during the future climatic warming,it is unlikel that sealevel will greatl rise in the next 100 or 200 ears.The best estimate for sealevel rise over the next centur is 50-I00cm.But relative sealevel changes are mainly controllod by various local factors,among which the most important is land subsidence.As the coastal region is the most densel populated and best developed area in the world,a relative sealevel rise of one meter will be a great threat to our society. The recent development in the study of global climatic changes and sealevel rise is as follows:1)It is realized that mankind has become a more important agent of environment changes than nature.Therefore,increasing attention is being paid to the stud of man’s role in the global change.2)Man developed countries have already started preparing for global warming and sealevel rise and a number of plans have been formulated and measures taken to combat these long-term threat.
