However, as sea levels rose, erosion reshaped the coast.

然而，随着平面上，被侵蚀。

The sea level will rise as well.

平面上。

It's over 1,000 feet below sea level.

它在平面以下1000英尺。

This causes the level of the oceans to rise.

这导致平面上。

This is the abnormal rise in sea levels as a hurricane blows water ashore.

当飓风临近时，平面会高。

Rising sea levels do not just threaten Tuvalu.

平面上不仅威胁图瓦卢。

This would contribute to rising global sea levels.

这将导致全球平面上。

Melting ice caps and rising sea levels.

融化的冰盖导致平面高。

And all that meltwater means rising seas.

而所有这些平面上。

Making the problem worse is rising sea level.

平面上问题变更糟。

Climate change means sea levels are rising.

气候变化引起平面上。

But, measuring sea levels shows the water raises an average of five and a half millimetres each year.

但是，测量平面显示，平面平均每年上5.5毫米。

It's over a hundred metres below the level of the sea.

它的地势低于平面100多米。

All around the world, sea levels are rising.

全世界的平面都在上。

Its coastal areas are threatened by rising sea levels.

其沿地区受到平面上的威胁。

That would be a 3-foot increase worldwide.

这将提平面差不多3英尺。

When the Earth spins on its axis, ocean levels stay the same.

当地球自转时，平面保持不变。

Now, that's just outside, at sea level.

那就在外面，在平面上。

It would mean that Antarctica is not contributing to seal level rise.

这意味着南极不会导致平面上。

The move is due to global warming and rising sea levels.

此次搬迁是由全球变暖和平面上所致。
