Ninety-nine percent of all freshwater ice on Earth

is sitting on top of Greenland and Antarctica,

正坐在格陵蘭島和南極洲之上。

and each year, a little more of it melts into the ocean.

每年都會有更多的東西融進海里

Normally, it would take hundreds to thousands of years

正常情況下，需要幾百年到幾千年的時間。

that caused a massive global melt overnight?

導致一夜之間全球大面積融化？

Coastal cities like New York, Shanghai, and London

紐約、上海、倫敦等沿海城市。

would drown in the apocalyptic mass flood,

會淹沒在世界末日的大洪水中。

forcing up to 40% of the world's population

迫使世界上多達40%的人口被迫離開。

當這一切混亂髮生在地面上的時候。

something equally sinister is happening below.

下面還發生了同樣邪惡的事情。

All that rising salt water will infiltrate

所有上升的鹽水都會滲入地下。

更遠的內陸地區的地下水儲備。

forcing its way into nearby freshwater aquifers.

迫使其進入附近的淡水含水層。

You know, the ones that supply our drinking water,

你知道，那些供應我們飲用水的人。

irrigation systems, and power-plant cooling systems?

On top of that, the ice on Greenland and Antarctica

除此之外，格陵蘭島和南極洲的冰層也是如此

is made of fresh water, so when it melts,

是由淡水製成的，所以當它融化後。

that's about 69% of the world's freshwater supply

這將會對我們的生活造成嚴重的破壞。

and relies on dense, salty water from the Arctic

並依靠來自北極的稠密鹹水為生

But a flood of fresh water would dilute the current

and could weaken or even stop it altogether.

temperatures in northern Europe would plummet,

這可能會催生一個小冰河時代。

that's not part of Greenland or Antarctica thaws.

這不是格陵蘭島或南極洲融化的一部分。

Some of that 1% is sitting in glaciers farther inland.

這1%中的一部分是在更遠的內陸的冰川中。

toxic chemicals like dichlorodiphenyltrichloroethane,

二氯二苯三氯乙烷等有毒化學品。

Scientists discovered that glaciers like this

可以將這些化學品儲存幾十年。

But as they thaw, those glaciers release the chemicals

但當它們解凍時，這些冰川會釋放出化學物質

into rivers, lakes, and groundwater reserves,

進入河流、湖泊和地下水保護區。

The rest of that 1% is hanging out underground,

凍土是一種有機物，它是被破壞的。

with thawing permafrost would be mercury poisoning.

That's right: There are an estimated 15 million gallons

of mercury stored up in the Arctic permafrost.

That's almost equal to the amount of mercury

On top of that, the organic matter in permafrost

除此之外，永久凍土中的有機物

two of the most potent greenhouse gases out there,

科學家們估計，這可能會增加一倍

the current levels of greenhouse gases in the atmosphere,

and potentially cause global temperatures to rise

by 3.5 degrees Celsius compared to today.

but say goodbye to that mini European ice age,

但告別了那個小型歐洲冰河時代。

and even rivers and lakes around the world.

They'd evaporate from the higher temperatures

and cause mass droughts and desert-like climates.

並造成大規模乾旱和類似沙漠的氣候。

And all that extra water vapor in the atmosphere

So all of that newly established coastline on the eastern US

所以，所有的新建立的海岸線 在美國東部的

would be one of the last places you'd want to live.

Instead, there would be mass migrations to Canada, Alaska,

反而會大量移民到加拿大、阿拉斯加。

the Arctic, and even what's left of the Antarctic.

北極，甚至是南極的剩餘部分。

And you're right, this is probably never going to happen.

你是對的，這可能永遠不會發生。

to cover the entire continent of North America

So the next time you hear about record-breaking heat

所以下次你聽到破紀錄的熱度時

at least you know that it could be worse.

But scientists estimate that if we don't take action

但科學家估計，如果我們不採取行動的話

and global temperatures increase by just 1 degree Celsius,

the effects of climate change we already see today

我們今天已經看到的氣候變化的影響

如果我們不小心的話，就會這樣。
