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) |
