下周，预计将有100多名州元首和其他高级政府官员来纽约市参加签署仪式巴黎协议adopted at COP21 last year。联合国预计仪式上的签名将超过任何其他国际协议的第一天签名，表现出对全球气候行动的压倒性政治支持。必威官网是真的吗

签名是第一个一个两步的过程为了使各国正式加入该协议 - 下一个是批准。一旦有55个关于气候变化框架框架公约（UNFCCC）至少55％的全球温室气体完成了这一过程，该协议将必威官网是真的吗“生效”，或生效并具有法律约束力。

UN Secretary-General Ban Ki Moonhas called forleaders to sign and ratify the Agreement as soon as possible. The momentum has already started, with a number of countries receiving approval from their parliaments to ratify ahead of the signing ceremony on April 22nd.

但是，各国将多久加入？跨越55-55个门槛，将巴黎协议逐渐达到最佳影响的国家需要哪些独特的国家？

介绍巴黎协议跟踪器

今天，Wri公开了巴黎协定跟踪器。交互式工具使人们能够监视国家在批准巴黎协议方面的进步，并允许用户创建，共享和嵌入自己的组合以生效。

在下面自己尝试一下。

在撰写此博客时，巴黎跟踪器地图是空白的，因为尚无国家签署或加入协议。通过攻击国家或选择地理或谈判群体，您可以看到各国的可能组合将越过排放和国家的门槛。

一些明显的见解包括：

我们至少需要前4个发射器中的一个

正如您可以在下面的情况下看到的那样，即使世界上其他每个国家都批准了协议，如果没有至少四个最大的发射器（中国，美国，欧盟和俄罗斯）中的至少一个，它也无法生效。

美国和中国在一起的方式最多但不是全部

这United States and Chinaannounced their intentionto sign the Paris Agreement on April 22, and committed to join the Agreement this year “as early as possible.” Each country must follow its respective domestic processes before ratifying. The United States can join based on the president’s authority, but for China, the approval of the Standing Committee of the National People's Congress is also required.

Combined, the United States and China account for about 38 percent of global emissions, which gives a major boost to efforts to reach the threshold for entry into force. We would still need a number of relatively large emitters, such as Russia, India, Japan, Brazil, Canada, Korea or Mexico, to come on board early to meet the 55 percent emissions threshold quickly.

我们现在在哪里？

许多国家，即斐济，帕劳，马歇尔群岛，马尔代夫和瑞士，已经完成了他们的国内批准程序，使他们能够在4月22日签署《巴黎协定》并批准。图瓦卢（Tuvalu）等其他人表示，他们将通过签署仪式这样做。

尽管这些国家仅代表着少量的全球排放量，但它们在早期批准方面的领导才能对获得所需的55个国家至关重要。如果其他小岛发展中国家和成员必威官网是真的吗气候脆弱的论坛ratified.

How Long Will it Take for the Paris Agreement to Enter into Force?

It is reasonable to think entry into force would happen in 2017, but it’s possible that a number of countries could join this year and pass the threshold for the Agreement to go into effect. But given the varying timelines for countries to complete their domestic approval processes, the timing of entry into force is uncertain.

For example, in Australia, the only requirement is formal notification and introduction of the Agreement in Parliament, whereas in Mexico, the consent of the Senate is also required. For Brazil, the approval of the National Congress is required, which means seeking approval of two separate houses of Parliament. And still other countries, such as Vietnam, apply different approval processes depending on the nature of the international agreement.

即使欧盟被认为是该协议的一个“政党”，它也可能必须与其28个成员国共同采取行动。每个成员国必须完成其国内批准程序，而在欧洲议会同意下，部长会议也将需要采取批准的决定。这可能需要几年的时间，但是如果没有欧盟，仍然有可能生效。

While some compare the Paris Agreement to theKyoto Protocolprocess, the previous international climate agreement, there are some important differences. Although the Kyoto Protocol followed a similar 55 Parties/55 percent of emissions approach, its threshold was based only on the二氧化碳排放发达国家。相比之下，《巴黎协定》生效的是所有国家的所有温室气体排放，因此比京都的七年来更快地采取法律效果。

这巴黎协定跟踪器shows the importance all countries play in bringing this international climate agreement into full effect. April 22 represents the next step in what was started last December. All countries should sign and join the Paris Agreement as soon as they are able to send a strong signal that they’re moving toward a low-carbon, climate-resilient world.
