Let’s talk about climate change. People are calling it the crisis of our time, and it is.

让我们谈谈气候变化。人们说它是我们这个时代的危机，事实也确实如此。

We started breaking CO2 records in 1950, and we haven’t stopped since. Why? Well, scientists say there’s a 95% chance that human activity is the cause.

我们从1950年开始打破二氧化碳排放记录，此后便一直没有停止过。为什么会这样？好吧，科学家说，95％的可能是由于人类活动造成的这种情况。

We’ve been burning more and more fossil fuels like oil and coal, which release CO2, to power our homes, factories, airplanes and cars.

我们一直在燃烧越来越多的化石燃料，例如石油和煤炭，这些矿物燃料会释放二氧化碳，为我们的房屋、工厂、飞机和汽车提供动力。

There’s also a lot more of us. The global population has tripled in the past 70 years.

另外还有越来越多的人口。过去70年全球人口增长了两倍。

And we’re consuming more products from animals that release another pollutant called Methane.

而且我们正在消费更多来自动物的产品，这些产品会释放出另一种叫做甲烷的污染物。

So all those gases are released into the air, and when sunlight gets into the earth’s atmosphere, some of the heat gets trapped, and the planet gets warmer. That’s why they call it the “Greenhouse Effect”.

因此，所有这些气体都释放到了空气中，当阳光进入地球的大气层时，一些热量被吸收下来，地球变得更暖，这就是为什么称其为“温室效应”。

But the concern is not that the earth is getting warmer. It’s that it’s happening far too quickly.

但需要担心的不是地球正在变暖。更重要的是它发展的太快了。

The UN says that right now, our world is about 1 degree hotter than pre-industrial times. That’s around the year 1800. Which is okay. In fact, the UN says if we warm by 1.5 degrees before the end of the century, we should be fine. The UN says even 2 degrees would 'probably' be alright.

联合国指出，我们的世界现在温度要比工业化前增长了大约1度，那是在1800年左右。这其实还可以接受。事实上，联合国说，如果我们在本世纪末之前升温1.5度，那应该还没有问题。联合国说，即使是上升2度，也“可能”没有太大问题。

But again, the problem is speed. Because right now, we are on track to hit 1.5 degrees in only ten years. And If we don't slow that warming down, it could mean catastrophe within my lifetime, and maybe yours too.

但问题在于上升的速度。因为现在我们很有可能在短短10年内就达到上升1.5度。如果我们不放慢升温的步伐，那对于你我来说可能意味着一生中最大的灾难。

And we’re already getting a taste. Sea levels are rising about 3 millimetres a year because seawater expands as temperatures get warmer. Melting ice sheets and glaciers also add trillions of tons of freshwater into our oceans.

而且我们已经开始尝到苦果了。海平面每年上升约3毫米，因为海水随着温度升高而膨胀。融化的冰盖和冰川还向我们的海洋中增加了数万亿吨的淡水。

People around the world are already losing their homes. And if things carry on, millions more of us will have to pack up too. Entire coastal cities could be underwater within 80 years, like Miami in the US or Osaka in Japan. Entire island nations in the pacific could completely disappear.

世界各地的人们已经在失去家园。如果事情继续下去，成百万的人将不得不转移搬家。整个沿海城市可能会在80年内被淹没，例如美国的迈阿密或日本的大阪。太平洋中的全部岛国可能都会完全消失。

Now, there is a plan to slow all this down. Back in 2016, world leaders signed the so-called “Paris Agreement”. And the big pledge is to cap temperatures rising by 1.5 degrees or a maximum of 2,  before the year 2100. So countries set their own targets on how much CO2 they emit.

现在，有一个计划可以减慢这些。2016年，世界各国领导人签署了《巴黎协定》，其最大的承诺是在2100年之前将温度上升幅度限制在1.5度或最高2度之内。因此，各国为排放的二氧化碳设定了自己的目标。

But experts say what’s needed now is an even bigger push to change everything about the way we run our world.

但是专家说，现在需要的是更大的动力来改变我们运行世界的方式。

So where does that leave us? Well there’s only so much bike-riding and light-bulb replacing you and I can do everyday. But the truth is that it’s those everyday things that are going to change anyway.

那我们该如何做呢？似乎只有改骑自行车或者使用节能灯泡这种日常事情可做。但事实是，正是这些日常的东西需要改变。

So the expert advice is that it’s down to all of us, to change our ways and shake things up, or climate change is going to do it for us.

因此专家的建议，就是气候变化是我们所有人的责任，我们要改变我们自己，否则气候变化将去改变我们。
