A massive alliance of more than 11,000 scientists have signed, sealed and delivered an important message to the world: if we don't make rapid, deep and lasting changes to our lives, they write, there will soon come "untold human suffering".
11,000多名科学家组成的庞大联盟已经向全世界签署、盖章并传递了一条重要的信息：他们写道，如果我们不迅速、深刻并持续改变我们的生活，“无尽的人类苦难”即将来临。
For more than 40 years, the word's scientists have warned of a looming climate crisis, and yet so far, their cries have been met with little attention and even fewer changes.
40多年来全球科学家已发出迫在眉睫的气候危机的警告，然而到目前为止，他们的呼声几乎没有得到重视，更别说人类做出的改变了。
Now, in the throes of a global emergency, with the echoes of their foresight gradually fading, experts have no choice but to try, try again.
现在面临全球危机，随着他们的远见产生的共鸣越来越少，专家们别无选择，只能一再尝试。
"Scientists have a moral obligation to warn humanity of any great threat," says environmental scientist Thomas Newsome from the University of Sydney.

"From the data we have, it is clear we are facing a climate emergency."
“从我们所掌握的数据来看，很明显我们正面临气候危机。”
Two years after authoring one of the most talked about climate papers - signed by the largest international group of scientists ever - Newsome and his colleagues have penned another urgent warning to the world.
两年前有史以来的国际科学家小组签署了一份关注的气候论文，这份论文由Newsome撰写，现在他再一次和同事们向全球发出紧急警告。
Encouraged by the recent global surge in environmental concern, their paper explores four decades-worth of publicly available data, covering energy use, surface temperature, population, deforestation, polar ice, fertility rates, and, of course, carbon emissions.
近全世界越来越担忧环境问题，他们的论文研究了四十年的公开数据，涵盖了能源使用、地表温度、人口、森林砍伐、极地冰、生育率，当然还有碳排放的问题。
Published for the first time now, it's already gathered an impressive signatory that falls just short of the first, including scientists from more than 150 different countries.
现在该论文首次出版就已吸引众多签名者，只不过比第一次差一点，其中包括来自150多个不同国家的科学家。
