With a large part of the world's po

With a large part of the world's population living close to the oceans, rising sea levels bring the potential for destructive (破坏性的)results. But scientists are still unable to make predictions exact enough for people to plan to handle the loss of land and the threat to coastal communities expected over this century.
“We know sea level is going to rise, but how much, and how fast, and where, we really still don’t know," said Josh Willis, a climate scientist.
The ocean isn't like water in a bathtub. It doesn’t rise all the same as more water pours in. As global warming raises sea levels, some places are expected to see higher-than-average increases, and a few places, may even see decreases.
It’s reported that over the course of this century, sea levels will rise between 8 inches and 6.6 feet around the planet. Scientists know this increase will be driven by the expansion of water as it warms—warmer water takes up more space—and the melting of ice. But the effects of warming water and melting ice on sea-level rise are expected to vary from area to area. And the melting of ice of the Antarctic and Greenland presents the largest uncertainty for the future, but air, land and water also play roles in changes to sea level. For example, sea level near the ice getting melt actually decreases, because the ground under the melting ice rises as the heavy ice disappears.
Climate change is expected to change ocean currents and the winds that help drive ocean currents. These changes will affect the distribution of heat within the oceans, and, as a result, affect changes in sea level.
Nowadays, scientists use two types of models to make predictions about the future of sea levels, but the two don’t agree. If scientists can't accurately predict sea-level increase for the coming years, the least we can do is measure what happening today with the help of the satellite, Jason-2, but it’s reaching the end of its operational life.

有很大一部分的世界人口居住在海洋，海平面上升带来的潜力为破坏性 (破坏性的) 结果。但科学家们仍无法作出确切的足以让人打算处理丧失土地和对沿海社区预计在本世纪的威胁的预测。"我们知道海平面正在上升，但多少，和速度有多快，和在哪里，我们真的还不知道，"乔希 · 威利，气候科学家说。海洋并不像浴缸里的水。随着更多的水倒在它不升起来都一样。随着全球变暖引起海平面上升，一些地方预计将看到优于平均水平的增加和几个地方，甚至可以看到跌幅。据报道，在本世纪末，海平面将升高 8 英寸和周围行星 6.6 英尺之间。科学家们知道这种增加将驱使水扩大，同时也温暖 — — 温暖的海水占用更多空间 — — 和融化的冰。但变暖水和融化的冰对海平面上升的影响预计将会从一个区域到另一个区域发生变化。南极和格陵兰的冰层融化的未来，提出了最大的不确定性，但空气、 土地和水也发挥作用的变化海平面。例如，海平面附近获取融冰实际上会降低，因为在融化的冰下地面上升，随着重冰消失。气候变化预计将改变洋流和帮助驱动器洋流的风。这些变化将影响的热量和海洋内分布情况和结果，影响海平面变化。如今，科学家们使用两种类型的模型，使海平面上升，对未来的预测，但这两个不同意。如果科学家不能准确地预测未来几年的海拔高度增加，的至少我们可以做是措施今天借助卫星，Jason-2，但它发生了什么事情达到了它的运行寿命。

随着世界人口居住在靠近海洋的很大一部分，海平面的上升带来的潜在破坏性（破坏性的）结果。但是，科学家们仍然无法预测准确的预测，让人们计划来处理这一世纪所带来的土地的损失和沿海地区的威胁。“我们知道海平面会上升，但多少，多快，我们真的还不知道，“Josh威利斯说，气候科学家。大海不像浴缸里的水。随着更多的水涌入，它并没有起到所有的增加。随着全球变暖，海平面上升，一些地方可能会看到高于平均水平的上升，以及一些地方，甚至可能会看到减少。据报道，在本世纪的过程中，海平面将上升8英寸和6.6英尺左右的行星。科学家们知道，这一增长将由水的扩张推动，随着它温暖的海水升温，增加更多的空间和冰的融化。但全球变暖的水和冰川融化对海平面上升的影响预计会有所不同。南极和格陵兰的冰川融化对未来最大的不确定性，但空气、陆地和水在海洋水平变化中扮演着角色。举例来说，海平面附近的冰融化实际减少，因为在冰融化的冰上升为冰消失。气候变化预计将改变海洋气流和帮助驱动海流的风。这些变化将影响到海洋中热量的分布，并因此影响海平面的变化。如今，科学家们用2种类型的模型来预测海平面的未来，但两者并不一致。如果科学家们不能准确地预测未来海平面上升，至少我们可以衡量什么今天发生的卫星Jason-2的帮助，但它达到其使用寿命结束。
