Well, good afternoon everybody. 大家下午好。
Gina, I want to thank you not just for the introduction, but for the incredible work that you and your team have been doing -- not just on this issue, but on generally making sure that we've got clean air, clean water, a great future for our kids. 吉娜，我要感谢你，不仅感谢你的介绍，更感谢你和你的团队所做的非凡工作——不仅在这个议题上，而且在总体上确保我们拥有清洁的空气、洁净的水源，以及我们孩子的美好未来。
I want to thank all the members of Congress who are here, as well, who have been fighting this issue, and sometimes at great odds with others, but are willing to take on what is going to be one of the key challenges of our lifetimes and future generations. I want to thank our Surgeon General, who's just been doing outstanding work and is helping to make the connection between this critical issue and the health of our families. 我还要感谢在座的各位国会议员，他们一直在为这个议题而奋斗，有时顶着巨大的压力，但他们愿意迎接这一将成为我们这一代人以及未来几代人面临的关键挑战之一。我要感谢我们的卫生局局长，她一直以来工作出色，正在帮助人们将这一关键议题与家庭健康联系起来。
Over the past six and a half years, we've taken on some of the toughest challenges of our time -- from rebuilding our economy after a devastating recession, to ending our wars in Iraq and Afghanistan and bringing almost all of our troops home, to strengthening our security through tough and principled diplomacy. But I am convinced that no challenge poses a greater threat to our future and future generations than a changing climate. And that's what brings us here today. 过去六年半以来，我们迎接了我们这个时代一些最艰巨的挑战——从在一场毁灭性的衰退后重建经济，到结束我们在伊拉克和阿富汗的战争并将几乎所有部队带回家，再到通过坚定而有原则的外交加强我们的安全。但我深信，没有任何挑战比气候变化对我们的未来和子孙后代构成更大的威胁。这就是我们今天聚在这里的原因。
Now, not everyone here is a scientist -- but some of you are among the best scientists in the world. And what you and your colleagues have been showing us for years now is that human activities are changing the climate in dangerous ways. Levels of carbon dioxide, which heats up our atmosphere, are higher than they've been in 800,000 years; 2014 was the planet's warmest year on record. 在座的并非每个人都是科学家——但你们中的一些人是世界上最顶尖的科学家。多年来，你们和你们的同事一直向我们表明，人类活动正在以危险的方式改变气候。使我们大气层升温的二氧化碳浓度达到了80万年来的最高水平；2014年是地球上有记录以来最热的一年。
And we've been setting a lot of records in terms of warmest years over the last decade. One year doesn't make a trend, but 14 of the 15 warmest years on record have fallen within the first 15 years of this century. 在过去十年中，我们不断创下最热年份的纪录。单一年份不能说明趋势，但有记录以来最热的15年中，有14年出现在本世纪的前15年。
Climate change is no longer just about the future that we're predicting for our children or our grandchildren; it's about the reality that we're living with every day, right now. 气候变化不再仅仅是我们为子女或孙辈预测的未来；它关乎我们每天、此刻正在经历的现实。
The Pentagon says that climate change poses immediate risks to our national security. While we can't say any single weather event is entirely caused by climate change, we've seen stronger storms, deeper droughts, longer wildfire seasons. Charleston and Miami now flood at high tide. Shrinking ice caps forced National Geographic to make the biggest change in its atlas since the Soviet Union broke apart. 五角大楼表示，气候变化对我们的国家安全构成直接风险。虽然我们不能说任何单一的天气事件完全由气候变化引起，但我们已经看到了更强烈的风暴、更严重的干旱、更长的野火季节。查尔斯顿和迈阿密现在在涨潮时就会发生洪水。不断缩小的冰盖迫使《国家地理》杂志做出了自苏联解体以来其地图集中最大的改动。
Over the past three decades, nationwide asthma rates have more than doubled, and climate change puts those Americans at greater risk of landing in the hospital. As one of America's governors has said, "We're the first generation to feel the impact of climate change and the last generation that can do something about it." 过去三十年来，全国哮喘发病率增加了一倍多，气候变化使这些美国人住院的风险更大。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，也是能够为此做些什么的最后一代人。"
And that's why I committed the United States to leading the world on this challenge, because I believe there is such a thing as being too late. 这就是为什么我承诺美国将在这一挑战上引领世界，因为我相信，有些事情一旦错过就为时已晚。
Most of the issues that I deal with -- and I deal with some tough issues that cross my desk -- by definition, I don't deal with issues if they're easy to solve because somebody else has already solved them. And some of them are grim. Some of them are heartbreaking. Some of them are hard. Some of them are frustrating. But most of the time, the issues we deal with are ones that are temporally bound and we can anticipate things getting better if we just kind of plug away at it, even incrementally. 我处理的大多数问题——我确实处理过一些摆在我桌上的棘手问题——按照定义，容易解决的问题不会到我这里来，因为别人已经解决了。其中一些问题很严峻，一些令人心碎，一些很艰难，一些令人沮丧。但大多数时候，我们处理的问题都是有时间限制的，只要我们坚持不懈，哪怕是循序渐进，我们都能预期情况会好转。
But this is one of those rare issues -- because of its magnitude, because of its scope -- that if we don't get it right we may not be able to reverse, and we may not be able to adapt sufficiently. There is such a thing as being too late when it comes to climate change. 但这是一个罕见的问题——由于其重要性，由于其范围——如果我们处理不当，我们可能无法逆转，我们可能无法充分适应。在气候变化问题上，真的有可能为时已晚。
Now, that shouldn't make us hopeless; it's not as if there's nothing we can do about it. We can take action. Over the past several years, America has been working to use less dirty energy, more clean energy, waste less energy throughout our economy. We've set new fuel economy standards that mean our cars will go twice as far on a gallon of gas by the middle of the next decade. Combined with lower gas prices, these standards are on pace to save drivers an average of $700 at the pump this year. 不过，这不应该让我们感到绝望；并非我们对此无能为力。我们可以采取行动。过去几年，美国一直在努力在整个经济中减少化石能源使用、增加清洁能源、降低能源浪费。我们制定了新的燃油经济性标准，这意味着到下一个十年中期，我们的汽车每加仑汽油的行驶里程将翻一番。再加上汽油价格下降，这些标准有望在今年为每位司机平均节省700美元的油费。
We doubled down on our investment in renewable energy. We're generating three times as much wind power, 20 times as much solar power as we did in 2008. 我们加大了对可再生能源的投资。我们的风力发电量是2008年的三倍，太阳能发电量是2008年的二十倍。
These steps are making a difference. Over the past decade, even as our economy has continued to grow, the United States has cut our total carbon pollution more than any other nation on Earth. That's the good news. But I am here to say that if we want to protect our economy and our security and our children's health, we're going to have to do more. The science tells us we have to do more. 这些措施正在产生效果。过去十年，即使我们的经济持续增长，美国的碳污染总削减量仍超过了地球上任何其他国家。这是好消息。但我在这里要说的是，如果我们想要保护我们的经济、我们的安全以及我们孩子的健康，我们必须做得更多。科学告诉我们必须做得更多。
This has been our focus these past six years. And it's particularly going to be our focus this month. In Nevada, later in August, I'll talk about the extraordinary progress we've made in generating clean energy -- and the jobs that come with it -- and how we can boost that even further. 这一直是我们过去六年的工作重点。而这个月，这将尤为成为我们的焦点。八月下旬，我将在内华达州谈谈我们在清洁能源生产方面取得的非凡进展——以及随之而来的就业机会——以及我们如何进一步推动这一进程。
I'll also be the first American President to visit the Alaskan Arctic, where our fellow Americans have already seen their communities devastated by melting ice and rising oceans, the impact on marine life. We're going to talk about what the world needs to do together to prevent the worst impacts of climate change before it's too late. 我还将成为第一位访问阿拉斯加北极地区的美国总统，在那里，我们的美国同胞已经亲眼目睹他们的社区因冰层融化和海平面上升以及对海洋生物的影响而遭受破坏。我们将讨论世界各国需要共同做些什么，以在为时已晚之前防止气候变化的最严重影响。
And today, we're here to announce America's Clean Power Plan -- a plan two years in the making, and the single most important step America has ever taken in the fight against global climate change. 而今天，我们在这里宣布美国的《清洁电力计划》——这项计划历时两年制定，是美国在应对全球气候变化斗争中采取的有史以来最重要的一步。
Right now, our power plants are the source of about a third of America's carbon pollution. That's more pollution than our cars, our airplanes and our homes generate combined. That pollution contributes to climate change, which degrades the air our kids breathe. But there have never been federal limits on the amount of carbon that power plants can dump into the air. 目前，我们的发电厂产生的碳污染约占美国碳污染的三分之一。这比我们的汽车、飞机和家庭产生的污染加起来还要多。这种污染加剧了气候变化，而气候变化又恶化了我们孩子呼吸的空气质量。但联邦政府从未对发电厂向空气中排放的碳量设过限制。
Think about that. We limit the amount of toxic chemicals like mercury and sulfur and arsenic in our air or our water -- and we're better off for it. But existing power plants can still dump unlimited amounts of harmful carbon pollution into the air. 想想看。我们限制空气或水中的汞、硫和砷等有毒化学物质的含量——我们因此而受益。但现有的发电厂仍然可以向空气中排放无限量的有害碳污染。
For the sake of our kids and the health and safety of all Americans, that has to change. For the sake of the planet, that has to change. 为了我们的孩子，为了所有美国人的健康与安全，这种情况必须改变。为了地球，这种情况必须改变。
So, two years ago, I directed Gina and the Environmental Protection Agency to take on this challenge. And today, after working with states and cities and power companies, the EPA is setting the first-ever nationwide standards to end the limitless dumping of carbon pollution from power plants. 因此，两年前，我指示吉娜和环境保护局迎接这一挑战。今天，在与各州、各城市和各电力公司合作之后，环保局正在制定有史以来第一项全国性标准，以终结发电厂无限量排放碳污染的局面。
Here's how it works. Over the next few years, each state will have the chance to put together its own plan for reducing emissions -- because every state has a different energy mix. Some generate more of their power from renewables; some from natural gas, or nuclear, or coal. And this plan reflects the fact that not everybody is starting in the same place. So we're giving states the time and the flexibility they need to cut pollution in a way that works for them. 具体是这样运作的。在未来几年里，每个州都将有机会制定自己的减排计划——因为每个州的能源结构都不同。有些州更多地依赖可再生能源发电；有些则依赖天然气、核能或煤炭。这项计划考虑到了并非所有人起点相同的事实。因此，我们给予各州所需的时间和灵活性，让它们以适合自己的方式减少污染。
And we'll reward the states that take action sooner instead of later -- because time is not on our side here. As states work to meet their targets, they can build on the progress that our communities and businesses are already making. 我们将奖励那些尽早采取行动的州——因为时间不等人。在各州努力实现目标的过程中，它们可以在我们的社区和企业已经取得的进展基础上再接再厉。
A lot of power companies have already begun modernizing their plants, reducing their emissions -- and by the way, creating new jobs in the process. Nearly a dozen states have already set up their own market-based programs to reduce carbon pollution. About half of our states have set energy efficiency targets. More than 35 have set renewable energy targets. Over 1,000 mayors have signed an agreement to cut carbon pollution in their cities. And last week, 13 of our biggest companies, including UPS and Walmart and GM, made bold, new commitments to cut their emissions and deploy more clean energy. 许多电力公司已经开始对其电厂进行现代化改造，减少排放——顺便说一句，在此过程中还创造了新的就业机会。近十几个州已经建立了自己的基于市场的碳污染减排计划。大约一半的州制定了能效目标。超过35个州制定了可再生能源目标。1000多位市长签署了在其城市削减碳污染的协议。上周，包括联合包裹、沃尔玛和通用汽车在内的13家美国最大企业做出了大胆的新承诺，将削减排放并部署更多清洁能源。
So the idea of setting standards and cutting carbon pollution is not new. It's not radical. What is new is that, starting today, Washington is starting to catch up with the vision of the rest of the country. And by setting these standards, we can actually speed up our transition to a cleaner, safer future. 因此，设定标准、削减碳污染的想法并不新鲜，也不是激进的。新鲜的是，从今天开始，华盛顿开始迎头赶上全国其他地区的愿景。通过设定这些标准，我们实际上可以加速向更清洁、更安全的未来转型。
With this Clean Power Plan, by 2030, carbon pollution from our power plants will be 32 percent lower than it was a decade ago. And the nerdier way to say that is that we'll be keeping 870 million tons of carbon dioxide pollution out of our atmosphere. The simpler, layman's way of saying that is it's like cutting every ounce of emission due to electricity from 108 million American homes. Or it's the equivalent of taking 166 million cars off the road. 根据这项《清洁电力计划》，到2030年，我们发电厂的碳污染将比十年前降低32%。用更专业的说法是，我们将减少8.7亿吨二氧化碳排放进入大气层。用更通俗的说法，这相当于减少了1.08亿个美国家庭用电产生的全部排放。或者说，相当于让1.66亿辆汽车停驶。
By 2030, we will reduce premature deaths from power plant emissions by nearly 90 percent -- and thanks to this plan, there will be 90,000 fewer asthma attacks among our children each year. And by combining this with greater investment in our booming clean energy sector, and smarter investments in energy efficiency, and by working with the world to achieve a climate agreement by the end of this year, we can do more to slow, and maybe even eventually stop, the carbon pollution that's doing so much harm to our climate. 到2030年，我们将把发电厂排放导致的过早死亡减少近90%——而且由于这项计划，每年我们孩子的哮喘发作将减少9万次。再加上对我们蓬勃发展的清洁能源部门的更多投资，以及对能效的更明智投资，再加上与世界各国合作在今年年底前达成一项气候协议，我们可以做更多工作来减缓——甚至可能最终阻止——对我们气候造成如此大危害的碳污染。
So this is the right thing to do. I want to thank, again, Gina and her team for doing it the right way. Over the longest engagement process in EPA history, they fielded more than 4 million public comments; they worked with states, they worked with power companies, and environmental groups, and faith groups, and people across our country to make sure that what we were doing was realistic and achievable, but still ambitious. 所以这是正确的做法。我要再次感谢吉娜和她的团队以正确的方式完成了这项工作。在环保局历史上最长的公众参与过程中，他们收集了超过400万条公众意见；他们与各州、各电力公司、环保组织、宗教组织以及全国人民合作，确保我们所做的事情既现实可行，又不失雄心。
And some of those people are with us here today. So, Tanya Brown -- Tanya, wave, go ahead -- there's Tanya. Tanya Brown has joined up with moms across America to spread the word about the dangers climate change poses to the health of our children -- including Tanya's daughter, Sanaa. There's Sanaa, right there. 其中一些人今天就在这里。那么，坦尼娅·布朗——坦尼娅，挥挥手，来吧——坦尼娅在那里。坦尼娅·布朗与全美各地的妈妈们一起，宣传气候变化对我们孩子健康的危害——包括坦尼娅的女儿萨娜。萨娜就在那里。
Dr. Sumita Khatri has spent her career researching the health impacts of pollution at the Cleveland Clinic, and helping families whose lives are impacted every single day. Doctor, thank you. 苏米塔·卡特里博士毕生都在克利夫兰诊所研究污染对健康的影响，并帮助那些日常生活受到影响的家庭。医生，谢谢你。
Sister Joan Marie Steadman has helped rally Catholic women across America to take on climate. Sister, thank you so much for your leadership. And she's got a pretty important guy on her side -- as Pope Francis made clear in his encyclical this summer, taking a stand against climate change is a moral obligation. And Sister Steadman is living up to that obligation every single day. 琼·玛丽·斯特德曼修女帮助动员了全美各地的天主教女性投身气候行动。修女，非常感谢你的领导力。她的身后还有一位相当重要的人物——正如教皇方济各在今年夏天的通谕中明确指出的那样，对气候变化表明立场是一项道德义务。斯特德曼修女每天都在履行这一义务。
Now, let's be clear. There will be critics of what we're trying to do. There will be cynics that say it cannot be done. Long before the details of this Clean Power Plan were even decided, the special interests and their allies in Congress were already mobilizing to oppose it with everything they've got. They will claim that this plan will cost you money -- even though this plan, the analysis shows, will ultimately save the average American nearly $85 a year on their energy bills. 现在，让我们明确一点。会有人对我们正在努力做的事情提出批评。会有人嗤之以鼻，说这不可能做到。早在《清洁电力计划》的细节确定之前，特殊利益集团及其在国会的盟友就已经在全力动员反对。他们会声称这项计划会让你花钱——尽管分析显示，这项计划最终将为每个美国人每年节省近85美元的能源账单。
They'll claim we need to slash our investments in clean energy, it's a waste of money -- even though they're happy to spend billions of dollars a year in subsidizing oil companies. They'll claim this plan will kill jobs -- even though our transition to a cleaner energy economy has the solar industry, to just name one example, creating jobs 10 times faster than the rest of the economy. 他们会声称我们需要削减对清洁能源的投资，说这是浪费钱——尽管他们每年乐于花费数十亿美元补贴石油公司。他们会声称这项计划会扼杀就业——尽管在我们向更清洁能源经济转型的过程中，仅举太阳能行业为例，其就业增长速度就是其他经济领域的十倍。
They'll claim this plan is a "war on coal," to scare up votes -- even as they ignore my plan to actually invest in revitalizing coal country, and supporting health care and retirement for coal miners and their families, and retraining those workers for better-paying jobs and healthier jobs. Communities across America have been losing coal jobs for decades. I want to work with Congress to help them, not to use them as a political football. Partisan press releases aren't going to help those families. 他们会声称这项计划是一场"对煤炭的战争"，以此来捞取选票——与此同时，他们对我的计划视而不见。我的计划是实实在在地投资振兴煤炭产区，支持煤矿工人及其家庭的医疗和退休保障，并为这些工人提供再培训，让他们获得收入更高、更健康的工作。几十年来，全美各地的社区一直在失去煤炭行业的工作岗位。我希望与国会合作帮助他们，而不是把他们当作政治皮球。党派性的新闻稿帮不了那些家庭。
Even more cynical, we've got critics of this plan who are actually claiming that this will harm minority and low-income communities -- even though climate change hurts those Americans the most, who are the most vulnerable. Today, an African-American child is more than twice as likely to be hospitalized from asthma; a Latino child is 40 percent more likely to die from asthma. So if you care about low-income, minority communities, start protecting the air that they breathe, and stop trying to rob them of their health care. You could also expand Medicaid in your states, by the way. 更讽刺的是，我们听到这项计划的批评者居然声称这会伤害少数族裔和低收入社区——尽管气候变化对这些最脆弱的美国人伤害最大。今天，非裔美国儿童因哮喘住院的可能性是其他儿童的两倍多；拉丁裔儿童死于哮喘的可能性高出40%。所以，如果你真的关心低收入少数族裔社区，那就开始保护他们呼吸的空气吧，别再想方设法剥夺他们的医疗保障了。顺便说一句，你们也可以在你们的州扩大医疗补助计划。
Here's the thing. We've heard these same stale arguments before. Every time America has made progress, it's been despite these kind of claims. Whenever America has set clear rules and smarter standards for our air, our water, our children's health, we get the same scary stories about killing jobs and businesses and freedom. It's true. 问题就在这里。这些陈词滥调我们以前都听过。每一次美国取得进步，都是顶着这种种说法实现的。每当美国为我们的空气、我们的水源、我们孩子的健康制定明确的规则和更明智的标准时，我们都会听到同样耸人听闻的说法，说什么会扼杀就业、毁掉企业、丧失自由。事实就是如此。
I'm going to go off script here just for a second. Because this is important -- because sometimes I think we feel as if there's nothing we can do. Tomorrow is my birthday, so I'm starting to reflect on age. And in thinking about what we were doing here today, I was reminded about landing in Los Angeles to attend a college as a freshman, as an 18-year-old. And it was late August. I was moving from Hawaii. 我要脱稿讲一会儿。因为这很重要——因为有时候我觉得我们好像认为自己无能为力。明天是我的生日，所以我开始思考年龄的问题。在思考我们今天在这里所做的事情时，我想起了18岁那年刚到洛杉矶上大学的情景。那是八月下旬。我从夏威夷搬过来。
And I got to the campus, and I decided -- I had a lot of pent-up energy and I wanted to go take a run. And after about five minutes, suddenly I had this weird feeling, I couldn't breathe. And the reason was, back in 1979, Los Angeles still was so full of smog that there were days where people who were vulnerable just could not go outside. And they were fairly frequent. 到了校园后，我觉得自己精力充沛，想去跑个步。可大约五分钟后，我突然有种奇怪的感觉，喘不过气来。原因是，1979年的洛杉矶烟雾弥漫，有些日子里体弱的人根本不能出门。而且这样的日子还相当频繁。
And folks who are older than me can remember the Cayuga River burning because of pollution, and acid rain threatening to destroy all the great forests of the Northeast. And you fast-forward 30, 40 years later, and we solved those problems. But at the time, the same characters who are going to be criticizing this plan were saying, this is going to kill jobs, this is going to destroy businesses, this is going to hurt low-income people, it's going to be wildly expensive. And each time, they were wrong. 比我年长的人应该还记得卡尤加河因污染而着火的事，还有酸雨曾威胁要摧毁东北部所有的原始森林。三四十年过去了，我们解决了那些问题。但在当时，那些即将批评这项计划的人也曾说过，这会扼杀就业，这会摧毁企业，这会伤害低收入人群，这会代价高昂。而每一次，他们都错了。
And because we pushed through, despite those scaremongering tactics, you can actually run in Los Angeles without choking. And folks can actually take a boat out on that river. And those forests are there. 正因为我们顶住了那些危言耸听的论调，坚持了下来，今天你才能在洛杉矶跑步而不被呛到。人们才能在那条河上划船。那些森林依然郁郁葱葱。
So we got to learn lessons. We got to know our history. The kinds of criticisms that you're going to hear are simply excuses for inaction. They're not even good business sense. They underestimate American business and American ingenuity. 所以我们必须吸取教训。我们必须了解我们的历史。你们将要听到的种种批评，不过是无所作为的借口。它们甚至不符合良好的商业逻辑。它们低估了美国企业和美国的创新精神。
In 1970, when Republican President Richard Nixon decided to do something about the smog that was choking our cities, they warned that the new pollution standards would decimate the auto industry. It didn't happen. Catalytic converters worked. Taking the lead out of gasoline worked. Our air got cleaner. 1970年，当共和党总统理查德·尼克松决定采取措施治理笼罩城市的烟雾时，有人警告说，新的污染标准将摧毁汽车工业。结果并没有。催化转换器奏效了。汽油无铅化奏效了。我们的空气变干净了。
In 1990, when Republican President George H.W. Bush decided to do something about acid rain, they said the bills would go up, our lights would go off, businesses would suffer "a quiet death." It didn't happen. We cut acid rain dramatically, and it cost much less than anybody expected -- because businesses, once incentivized, were able to figure it out. 1990年，当共和党总统乔治·赫伯特·沃克·布什决定采取措施治理酸雨时，有人说电费会上涨，灯会熄灭，企业会"悄然死亡"。结果并没有。我们大幅减少了酸雨，而且成本比任何人预期的都低得多——因为企业一旦有了激励，就能找到办法。
When we restricted leaded fuel in our cars, cancer-causing chemicals in plastics, it didn't end the oil industry, it didn't end the plastics industry; American chemists came up with better substitutes. The fuel standards we put in place a couple of years ago didn't cripple automakers. The American auto industry retooled. Today, our automakers are selling the best cars in the world at a faster pace than they have in almost a decade. They've got more hybrids, and more plug-ins, and more high fuel-efficient cars, giving consumers more choice than ever before, and saving families at the pump. 当我们限制汽车使用含铅汽油、限制塑料中的致癌化学物质时，石油工业没有终结，塑料工业也没有终结；美国化学家研发出了更好的替代品。我们几年前制定的燃油标准没有让汽车制造商陷入困境。美国汽车工业进行了重组。今天，我们的汽车制造商正在以近十年来最快的速度销售世界上最好的汽车。他们有了更多的混合动力车、更多的插电式电动车、更多的高燃油效率汽车，给消费者带来了前所未有的更多选择，也为家庭节省了油费。
We can figure this stuff out as long as we're not lazy about it; as long as we don't take the path of least resistance. Scientists, citizens, workers, entrepreneurs -- together as Americans, we disrupt those stale, old debates, upend old ways of thinking. Right now, we're inventing whole new technologies, whole new industries -- not looking backwards, we're looking forwards. 只要我们不懈怠，只要我们不走阻力最小的道路，我们就能解决这些问题。科学家、公民、工人、企业家——作为美国人，我们共同打破那些陈腐的旧争论，颠覆旧的思维方式。此时此刻，我们正在创造全新的技术、全新的产业——我们不向后看，我们向前看。
And if we don't do it, nobody will. The only reason that China is now looking at getting serious about its emissions is because they saw that we were going to do it, too. When the world faces its toughest challenges, America leads the way forward. That's what this plan is about. 如果我们不做，就没有人会做。中国现在开始认真对待其排放问题的唯一原因，就是因为他们看到我们也将这样做。当世界面临最严峻的挑战时，美国总是引领前进的方向。这就是这项计划的意义所在。
Now, I don't want to fool you here. This is going to be hard; dealing with climate change in its entirety, it's challenging. No single action, no single country will change the warming of the planet on its own. But today, with America leading the way, countries representing 70 percent of the carbon pollution from the world's energy sector have announced plans to cut their greenhouse gas emissions. In December, with America leading the way, we have a chance to put in place one of the most ambitious international climate agreements in human history. 现在，我不想哄你们。这将是艰难的；全面应对气候变化是一项挑战。没有任何单一行动、任何单一国家能够凭一己之力改变地球变暖的趋势。但今天，在美国的带领下，占世界能源部门碳污染70%的国家已经宣布了削减温室气体排放的计划。12月，在美国的带领下，我们有机会达成人类历史上最具雄心的国际气候协议之一。
And it's easy to be cynical and to say climate change is the kind of challenge that's just too big for humanity to solve. I am absolutely convinced that's wrong. We can solve this thing. But we have to get going. It's exactly the kind of challenge that's big enough to remind us that we're all in this together. 人们很容易抱持怀疑态度，说气候变化是人类无法解决的巨大挑战。我绝对相信这种说法是错误的。我们能够解决这个问题。但我们必须行动起来。正是这种巨大的挑战，足以提醒我们，我们休戚与共。
Last month, for the first time since 1972, NASA released a "blue marble," a single snapshot of the Earth taken from outer space. And so much has changed in the decades between that first picture and the second. Borders have shifted, generations have come and gone, our global population has nearly doubled. But one thing hasn't changed -- our planet is as beautiful as ever. It still looks blue. And it's as vast, but also as fragile, as miraculous as anything in this universe. 上个月，美国宇航局发布了自1972年以来的首张"蓝色弹珠"照片——一张从外太空拍摄的地球全景照。从第一张照片到第二张照片的这几十年间，发生了翻天覆地的变化。疆界变迁，世代更迭，全球人口几乎翻了一番。但有一件事没有改变——我们的星球依然美丽如初。它看起来依然蔚蓝。它依然浩瀚无垠，但也依然脆弱，一如宇宙间的任何奇迹。
This "blue marble" belongs to all of us. It belongs to these kids who are here. There are more than 7 billion people alive today; no matter what country they're from, no matter what language they speak, every one of them can look at this image and say, "That's my home." And "we're the first generation to feel the impact of climate change; we're the last generation that can do something about it." We only get one home. We only get one planet. There's no plan B. 这颗"蓝色弹珠"属于我们所有人。它属于在座的这些孩子。今天有70多亿人活着；无论他们来自哪个国家，无论他们说什么语言，每个人都可以看着这张图像说："那是我的家。"还有那句话："我们是感受到气候变化影响的第一代人；我们是能够为此做些什么的最后一代人。"我们只有一个家园。我们只有一个星球。没有备用方案。
I don't want my grandkids not to be able to swim in Hawaii, or not to be able to climb a mountain and see a glacier because we didn't do something about it. I don't want millions of people's lives disrupted and this world more dangerous because we didn't do something about it. That would be shameful of us. This is our moment to get this right and leave something better for our kids. Let's make the most of that opportunity. 我不希望我的孙辈因为我们没有采取行动而不能在夏威夷游泳，或者不能爬山看冰川。我不希望数百万人的生活受到扰乱，世界因为我们没有采取行动而变得更加危险。那将是我们的耻辱。这是我们做出正确选择、为子孙后代留下更美好家园的时刻。让我们好好把握这个机会。
Thank you, everybody. God bless you. God bless the United States of America. 谢谢大家。上帝保佑你们。上帝保佑美利坚合众国。
