rising sea level Sea level rises are a possible consequence of global warming. As the amount of free water in the ocean increases, and as the water becomes warmer, global warming will increase. In addition, according to theory, the heating at the poles may reduce the amount of water trapped in glaciers and ice caps. By the year 3000, the seas could rise between one and two metres. Such an event would clearly threaten low-lying areas, particularly in Asia, where million of people live and farm on river deltas and flood plains (全球变暖导致海平面上升。随着海洋中的水量的增加、水温的升高，全球变暖将进一步加剧。此外，理论研究表明，两极地区的升温会减少冰川和冰盖的数量。到3000年，海平面将上升1到2米。这将会影响低洼地区，特别是亚洲，那里有数百万居民在河口的三角洲地带和冲击平原上生活和耕作。) |
