如果所有的冰都融化了，地球会是什么样子?

We've learned over the past few years that global sea levels are rising at a rapid pace as global warming melts Earth's ice.

在过去的几年里，我们了解到，由于全球变暖地球的冰被融化，全球海平面正在迅速上升。

The consequence of this much ice melting so quickly is dangerous.

冰融化速度如此之快的后果是很危险的。

The United Nations Intergovernmental Panel on Climate Change and NASA warned a couple of years ago that many impacts of climate change are already irreversible and that sea levels will rise at least 90 centimeters in the coming decades.

联合国政府间气候变化委员会和NASA在几年前警告说，气候变化的许多影响已经不可逆转，在未来的几十年里海平面至少会上升90厘米。

The coastal U.S. cities like New York, Houston, New Orleans, Miami, San Diego, San Francisco and many more all will be covered in water. Many more international cities would face the same fate.

美国沿海城市，如纽约、休斯顿、新奥尔良、迈阿密、圣地亚哥、旧金山等都都将被水覆盖，更多的国际城市也将面临同样的命运。

It's a terrifying look at what the future could hold, but hopefully projections like this one can lead to a unified effort across the globe to combat it. If not, there's going to be a lot of moving going on.

这是一个可怕的景象，未来可能会这样发展，但希望像这样的预测可以引起全球范围内统一的努力，共同与之斗争。如果不这样的话，更多的变化将会上演，事情会变得更糟。
