President Hollande, Mr. Secretary General, fellow leaders. We have come to Paris to show our resolve. 奥朗德总统，秘书长先生，各位领导人。我们来到巴黎，彰显我们的决心。
We offer our condolences to the people of France for the barbaric attacks on this beautiful city. We stand united in solidarity not only to deliver justice to the terrorist network responsible for those attacks but to protect our people and uphold the enduring values that keep us strong and keep us free. And we salute the people of Paris for insisting this crucial conference go on -- an act of defiance that proves nothing will deter us from building the future we want for our children. What greater rejection of those who would tear down our world than marshaling our best efforts to save it? 我们对这座美丽城市遭受的野蛮袭击向法国人民表示慰问。我们团结一致，不仅要将发动这些袭击的恐怖网络绳之以法，还要保护我们的人民，捍卫使我们强大、使我们自由的永恒价值观。我们向巴黎人民致敬，因为他们坚持召开这次至关重要的会议——这是一种反抗行动，证明没有什么能阻止我们为子孙后代建设我们想要的未来。还有什么比全力以赴拯救我们的世界更能驳斥那些妄图摧毁我们世界的人呢？
Nearly 200 nations have assembled here this week -- a declaration that for all the challenges we face, the growing threat of climate change could define the contours of this century more dramatically than any other. What should give us hope that this is a turning point, that this is the moment we finally determined we would save our planet, is the fact that our nations share a sense of urgency about this challenge and a growing realization that it is within our power to do something about it. 近两百个国家本周齐聚于此——这表明，尽管我们面临种种挑战，但气候变化带来的日益严重的威胁可能比其他任何挑战都更能深刻地塑造本世纪的面貌。让我们有理由相信这是一个转折点、相信我们终于下定决心拯救地球的，是这样一个事实：我们各国对这一挑战有着共同的紧迫感，并且日益认识到，我们有能力为此采取行动。
Our understanding of the ways human beings disrupt the climate advances by the day. Fourteen of the fifteen warmest years on record have occurred since the year 2000 -- and 2015 is on pace to be the warmest year of all. No nation -- large or small, wealthy or poor -- is immune to what this means. 我们对人类破坏气候方式的认识日益加深。有记录以来最热的十五个年份中，有十四个出现在两千年之后——而二〇一五年有望成为有史以来最热的一年。没有哪个国家——无论大小、贫富——能免受其影响。
This summer, I saw the effects of climate change firsthand in our northernmost state, Alaska, where the sea is already swallowing villages and eroding shorelines; where permafrost thaws and the tundra burns; where glaciers are melting at a pace unprecedented in modern times. 今年夏天，我在我们最北部的阿拉斯加州亲眼目睹了气候变化的影响：海水正在吞噬村庄、侵蚀海岸线；永久冻土在融化，苔原在燃烧；冰川正以现代史上前所未有的速度消融。
And it was a preview of one possible future -- a glimpse of our children's fate if the climate keeps changing faster than our efforts to address it. Submerged countries. Abandoned cities. Fields that no longer grow. Political disruptions that trigger new conflict, and even more floods of desperate peoples seeking the sanctuary of nations not their own. 这预示着一种可能的未来——如果气候变化的速度继续超过我们应对的努力，我们的子孙后代将面临怎样的命运。被淹没的国家。被遗弃的城市。不再生长庄稼的田野。引发新冲突的政治动荡，以及更多绝望的民众涌入其他国家寻求庇护的难民潮。
That future is not one of strong economies, nor is it one where fragile states can find their footing. That future is one that we have the power to change. Right here. Right now. But only if we rise to this moment. As one of America's governors has said, "We are the first generation to feel the impact of climate change, and the last generation that can do something about it." 那样的未来不会有强劲的经济，脆弱的国家也无法在其中立足。那样的未来是我们有能力改变的。就在这里。就在此刻。但前提是我们必须挺身而出。正如美国一位州长所说："我们是感受到气候变化影响的第一代人，也是能够为此采取行动的最后一代人。"
I've come here personally, as the leader of the world's largest economy and the second-largest emitter, to say that the United States of America not only recognizes our role in creating this problem, we embrace our responsibility to do something about it. 我以全球最大经济体和第二大排放国领导人的身份亲自来到这里，就是要表明，美利坚合众国不仅认识到我们在造成这一问题上的责任，我们也承担起为此采取行动的责任。
Over the last seven years, we've made ambitious investments in clean energy, and ambitious reductions in our carbon emissions. We've multiplied wind power threefold, and solar power more than twentyfold, helping create parts of America where these clean power sources are finally cheaper than dirtier, conventional power. 过去七年来，我们在清洁能源方面进行了雄心勃勃的投资，同时大幅削减了碳排放。我们将风电装机容量增加了两倍，太阳能发电增加了二十多倍，这使得美国部分地区的清洁能源价格终于低于污染更严重的传统能源。
We've invested in energy efficiency in every way imaginable. We've said no to infrastructure that would pull high-carbon fossil fuels from the ground, and we've said yes to the first-ever set of national standards limiting the amount of carbon pollution our power plants can release into the sky. 我们以各种可以想象的方式投资于能源效率。我们对开采高碳化石燃料的基础设施说不，对有史以来第一套限制发电厂向大气排放碳污染的国家标准说是。
The advances we've made have helped drive our economic output to all-time highs, and drive our carbon pollution to its lowest levels in nearly two decades. 我们取得的进展帮助我们的经济产出达到历史新高，同时将碳污染降至近二十年来的最低水平。
But the good news is this is not an American trend alone. Last year, the global economy grew while global carbon emissions from burning fossil fuels stayed flat. And what this means can't be overstated. We have broken the old arguments for inaction. We have proved that strong economic growth and a safer environment no longer have to conflict with one another; they can work in concert with one another. 但好消息是，这并非美国独有的趋势。去年，全球经济实现增长，而燃烧化石燃料产生的全球碳排放却保持平稳。这一意义怎么强调都不为过。我们打破了那些主张不作为的旧论调。我们已经证明，强劲的经济增长和更安全的环境不再相互矛盾；它们可以协同并进。
And that should give us hope. One of the enemies that we'll be fighting at this conference is cynicism, the notion we can't do anything about climate change. Our progress should give us hope during these two weeks -- hope that is rooted in collective action. 这应该给我们带来希望。我们将在本次大会上与之斗争的敌人之一是犬儒主义——那种认为我们对气候变化无能为力的观念。我们取得的进展应该在这两周里给我们带来希望——植根于集体行动的希望。
Earlier this month in Dubai, after years of delay, the world agreed to work together to cut the super-pollutants known as HFCs. That's progress. Already, prior to Paris, more than 180 countries representing nearly 95 percent of global emissions have put forward their own climate targets. That is progress. 本月早些时候在迪拜，经过多年拖延，世界各国同意共同努力削减被称为氢氟碳化物的超级污染物。这就是进步。在巴黎会议之前，已有一百八十多个国家（代表近百分之九十五的全球排放量）提出了各自的气候目标。这就是进步。
For our part, America is on track to reach the emissions targets that I set six years ago in Copenhagen -- we will reduce our carbon emissions in the range of 17 percent below 2005 levels by 2020. And that's why, last year, I set a new target: America will reduce our emissions 26 to 28 percent below 2005 levels within 10 years from now. 就美国而言，我们正朝着我六年前在哥本哈根设定的排放目标稳步前进——到二〇二〇年，我们将把碳排放量在二〇〇五年的基础上减少约百分之十七。正因如此，去年我设定了一个新目标：从现在起十年内，美国将在二〇〇五年的基础上减少百分之二十六至二十八的排放。
So our task here in Paris is to turn these achievements into an enduring framework for human progress -- not a stopgap solution, but a long-term strategy that gives the world confidence in a low-carbon future. 因此，我们在巴黎的任务是将这些成就转化为人类进步的持久框架——不是权宜之计，而是一项让世界对低碳未来充满信心的长期战略。
Here, in Paris, let's secure an agreement that builds in ambition, where progress paves the way for regularly updated targets -- targets that are not set for each of us but by each of us, taking into account the differences that each nation is facing. 在巴黎，让我们达成一项兼具雄心的协议，让进展为定期更新目标铺平道路——这些目标不是由他人为我们设定的，而是由我们自己设定的，同时考虑到每个国家所面临的不同情况。
Here in Paris, let's agree to a strong system of transparency that gives each of us the confidence that all of us are meeting our commitments. And let's make sure that the countries who don't yet have the full capacity to report on their targets receive the support that they need. 在巴黎，让我们商定一个强有力的透明度机制，让每个国家都相信所有国家都在履行各自的承诺。同时，让我们确保那些尚未完全具备报告目标能力的国家获得它们所需的支持。
Here in Paris, let's reaffirm our commitment that resources will be there for countries willing to do their part to skip the dirty phase of development. And I recognize this will not be easy. It will take a commitment to innovation and the capital to continue driving down the cost of clean energy. And that's why, this afternoon, I'll join many of you to announce an historic joint effort to accelerate public and private clean energy innovation on a global scale. 在巴黎，让我们重申我们的承诺：对于那些愿意尽自己一份力量、跨越高污染发展阶段的国家，我们将提供资源支持。我知道这并非易事。这需要致力于创新，并投入资金继续降低清洁能源的成本。正因如此，今天下午，我将与在座许多人一道，宣布一项历史性的联合行动，在全球范围内加速公共和私营部门的清洁能源创新。
Here in Paris, let's also make sure that these resources flow to the countries that need help preparing for the impacts of climate change that we can no longer avoid. We know the truth that many nations have contributed little to climate change but will be the first to feel its most destructive effects. For some, particularly island nations -- whose leaders I'll meet with tomorrow -- climate change is a threat to their very existence. 在巴黎，让我们也确保这些资源流向那些需要帮助以应对我们已无法避免的气候变化影响的国家。我们知道一个事实：许多国家对气候变化的贡献微乎其微，却将最先感受到其最具破坏性的影响。对一些国家来说，尤其是小岛屿国家——我明天将会见它们的领导人——气候变化威胁到它们的生存。
And that's why today, in concert with other nations, America confirms our strong and ongoing commitment to the Least Developed Countries Fund. And tomorrow, we'll pledge new contributions to risk insurance initiatives that help vulnerable populations rebuild stronger after climate-related disasters. 正因如此，今天，美国与其他国家一道，确认我们对最不发达国家基金的坚定和持续承诺。明天，我们将为风险保险倡议认捐新的资金，帮助脆弱群体在气候相关灾害后重建得更加强大。
And finally, here in Paris, let's show businesses and investors that the global economy is on a firm path towards a low-carbon future. If we put the right rules and incentives in place, we'll unleash the creative power of our best scientists and engineers and entrepreneurs to deploy clean energy technologies and the new jobs and new opportunities that they create all around the world. There are hundreds of billions of dollars ready to deploy to countries around the world if they get the signal that we mean business this time. Let's send that signal. 最后，在巴黎，让我们向企业和投资者表明，全球经济正坚定地走向低碳未来。如果我们制定正确的规则和激励措施，我们将释放出最优秀的科学家、工程师和企业家的创造力，在世界各地推广清洁能源技术，以及它们所创造的新就业和新机遇。如果各国收到我们这次是认真的信号，数千亿美元将随时准备投向世界各国。让我们发出这个信号。
That's what we seek in these next two weeks. Not simply an agreement to roll back the pollution we put into our skies, but an agreement that helps us lift people from poverty without condemning the next generation to a planet that's beyond its capacity to repair. Here, in Paris, we can show the world what is possible when we come together, united in common effort and by a common purpose. 这就是我们在接下来两周里所要追求的。不仅仅是达成一项减少我们向大气排放污染的协议，更是一项帮助人们摆脱贫困、同时不让下一代承受一个已无法修复的星球的协议。在巴黎，我们可以向世界展示，当我们团结一心、共同努力时，什么是可能的。
And let there be no doubt, the next generation is watching what we do. Just over a week ago, I was in Malaysia, where I held a town hall with young people, and the first question I received was from a young Indonesian woman. And it wasn't about terrorism, it wasn't about the economy, it wasn't about human rights. It was about climate change. And she asked whether I was optimistic about what we can achieve here in Paris, and what young people like her could do to help. 毫无疑问，年轻一代正在注视着我们的一举一动。就在一周多前，我在马来西亚与年轻人举行了一场市政厅会议，我收到的第一个问题来自一位年轻的印尼女性。那不是关于恐怖主义，不是关于经济，也不是关于人权。而是关于气候变化。她问我对我们能在巴黎取得什么成果是否持乐观态度，以及像她这样的年轻人能做些什么来提供帮助。
I want our actions to show her that we're listening. I want our actions to be big enough to draw on the talents of all our people -- men and women, rich and poor -- I want to show her passionate, idealistic young generation that we care about their future. 我希望我们的行动能向她表明，我们在倾听。我希望我们的行动足够宏大，能够汇集所有人的才智——无论男女、无论贫富——我想向她那充满热情、富有理想的年轻一代表明，我们关心他们的未来。
For I believe, in the words of Dr. Martin Luther King, Jr., that there is such a thing as being too late. And when it comes to climate change, that hour is almost upon us. But if we act here, if we act now, if we place our own short-term interests behind the air that our young people will breathe, and the food that they will eat, and the water that they will drink, and the hopes and dreams that sustain their lives, then we won't be too late for them. 因为我相信，用马丁·路德·金博士的话来说，有些事情为时已晚。而在气候变化问题上，那个时刻几乎已经来临。但如果我们在这里行动，如果我们现在就行动，如果我们把自己的短期利益放在年轻人将要呼吸的空气、将要吃的食物、将要喝的水，以及支撑他们生命的希望和梦想之后，那么对他们来说，我们还不算太晚。
And, my fellow leaders, accepting this challenge will not reward us with moments of victory that are clear or quick. Our progress will be measured differently -- in the suffering that is averted, and a planet that's preserved. And that's what's always made this so hard. Our generation may not even live to see the full realization of what we do here. 各位领导人，接受这一挑战不会给我们带来明确或迅速的胜利时刻。我们的进步将以不同的方式来衡量——以避免了多少苦难，以保护了多少地球。这就是这件事一直如此艰难的原因。我们这一代人甚至可能无法亲眼看到我们在这里所做努力的全部成果。
But the knowledge that the next generation will be better off for what we do here -- can we imagine a more worthy reward than that? Passing that on to our children and our grandchildren, so that when they look back and they see what we did here in Paris, they can take pride in our achievement. 但是，知道下一代将因我们在这里的努力而生活得更好——还有什么比这更有价值的回报呢？把这一切传递给我们的子孙后代，这样当他们回首往事，看到我们在巴黎所做的一切时，他们会为我们的成就感到自豪。
Let that be the common purpose here in Paris. A world that is worthy of our children. A world that is marked not by conflict, but by cooperation; and not by human suffering, but by human progress. A world that's safer, and more prosperous, and more secure, and more free than the one that we inherited. 让这成为我们在巴黎的共同目标。一个无愧于我们子孙后代的世界。一个不以冲突为特征、而以合作为特征的世界；一个不以人类苦难为特征、而以人类进步为特征的世界。一个比我们继承的世界更安全、更繁荣、更稳固、更自由的世界。
Let's get to work. 让我们开始行动吧。
Thank you very much. 非常感谢大家。
