Starting later this month, the French government is planning to host its largest conference ever, 40,000 delegates representing 195 countries, including China, India and the U.S. Those three nations produced the largest amounts of carbon dioxide, which most scientists say is causing earth`s average temperatures to heat up.

从本月底开始，法国政府已经开始计划举办会有来自195个国家4000多名代表参加的最大型的会议，其中包括中国、印度、美国在内。这三个国家产生的二氧化碳的量最多，大多科学家称这导致了平均气温上升。

A smaller group disagrees, saying climate change happens naturally and the earth can absorb the CO2 from human activities. But that will be the focused of COP21.

但是仍有一些群体不同意上述说法，称，气候变化是自然发生的，地球会吸收人类活动所排放的二氧化碳。该问题就是第二十一届联合国气候变化大会关注的重点。

So, you may have seen this term COP21 popping up in your Twitter feed. COP21 means the Conference of Parties. It`s the 21st time essentially that the world has come together to try to figure out a solution to climate change. This is something that we`ve never succeeded at before but there`s very good reason to think that this year in December in Paris when the world meets again, that we`ll be able to figure out something that will get us on the right track.

你可能在自己的推特简讯上看过COP21这个词汇。COP21意味着缔约国大会。实际上在21实际，世界各国聚到一起来为气候变化找到解决方案。关于这个问题我们从未成功过，但是在今年12月份在巴黎有合适的理由来思考这个问题。那时候世界各国相聚到一起，那时，我们就能够找到让我们恢复正轨的一些问题的答案。

When all these world leaders get together in Paris, they`re basically going to be talking about one number, and that number is 2 degree Celsius.

当世界各国领导人相聚在巴黎，他们基本上会谈论一个数字，这个数字是2摄氏度。

That`s the threshold for warming. It`s measured since the start of the Industrial Revolution.

这是温度变暖的门槛。自工业革命开始，开始用这个数字来衡量冷暖。

And if we cross that mark, we`re expected to go into what policy wonks considered the danger zone or dangerous territory for climate change.

如果我们超越了那个标记，估计人类就进入了那些政策专家们认为的气候变化的危险地带。

There are entire countries that could disappear because of sea level rise at that mark. Wildfires re expected to get bigger. Droughts will get more severe and 30 percent of animals will be put at risk for extinction.

由于在那个温度时，海平面开始上升，所有的国家都有可能消失。干旱情形可能会变得愈发严重，30%的动物都会濒临灭绝。

I`ve seen these talks describe as basically a potluck dinner. And each country in the world is bringing its dish, its climate plan to the table and saying, OK, here`s what my plan is, like what are you bringing?

我觉得这些谈判可以描述成为百乐餐。与会的每个国家都都会将自己关于气候变化的计划书呈现到餐桌上，这是我的计划，你带来的计划呢?

There are huge stakes of these talks. But as far as what`s going to be happening in Paris, it maybe a lot of really kind of smaller things.

这些会占该次会谈的一大部分。但是至于在巴黎会发生什么，或许相比之下，可能微不足道。

Countries will be fighting about, you know, how aggressive these cuts to fossil fuels are, exactly who`s going to pay for countries to adopt to climate change, and how often these goals are going to be reviewed going forward.

各国将会争论，削减化石燃料的严重程度，谁来为履行气候变化的国家买账、以及之后这些目标将如何审查。

And the fact that U.S. and China are both bringing dishes to this giant international potluck is a huge deal for the Paris climate talks. That really hasn`t happened before. China and the U.S. are the two biggest climate polluters in the world. And previously, they`ve sort of stalled or gave mixed messages in terms of, you know, what they were going to do to get off of fossil fuels.

There are huge stakes of these talks. But as far as what`s going to be happening in Paris, it maybe a lot of really kind of smaller things.
