澳门mg娱乐网址:科学家宣布地质纪元进入人类世

2020-08-25 06:48:02

【mg娱乐官网】The 11,700-year-old Holocene epoch is over. Were now living in the Anthropocene epoch.长达11700年的全新世完结啦。我们如今于是以生活在“人类世”纪元。You don’t need to be paying much attention to the world around you to know that humans are having a massive influence on the planet, but our influence is now on the way to being officially recognised in geologic terms.需要劳神费力,我们都能感受到人类对地球产生的极大影响。

如今,地质学界想用地质术语来证实这些影响。The 11,700-year-old geological Holocene epoch has ended, scientists say, and we’re now living in the Anthropocene: an era defined by humanity’s influence on the world around us.科学家回应,长达11700年的全新世已完结,我们现在于是以生活在“人类世”:即人类活动对地球施加影响的时代。In fact, unless you’re over the age of 66, you’ve always been living in it. A 35-strong team of international researchers from the Working Group on the Anthropocene voted 30-3 (two were absent) in favour of the epoch shift, and the starting date is 1950.事实上,66岁以下的人自出生于起就生活在这个纪元了。

一支由35位国际顶尖研究者构成的“人类世”工作小组积极开展了纪元更加逆与否的投票,投票结果以30比3(有两位研究人员缺席)的压倒性优势宣告地质纪元转入“人类世”,并将开始时间确认为1950年。The date isn’t random: it matches when the first nuclear tests created a new stratum in the planet’s surface.这个日期可不是随意以定的:它与首批核试验对地质表面导致影响的时间吻合。Actually, it won’t necessarily be nuclear tests that ended the Holocene. Humanity’s impact on the planet is so great that we’re left “spoiled for choice” in terms of which particular signal to choose.实质上,核试验并非完结全新世的唯一必要条件。

人类活动对地球的影响是如此深刻印象,可供选择的因素真是多到让人“眼花缭乱”,很难送交究竟哪一因素起了决定性起到。Plastic pollution, soot from power plants, concrete and even domestic chicken bones were considered possible contenders.塑料污染,发电厂煤烟,钢筋混泥土,甚至是家养鸡的骨头都被列为有可能的影响因素。

“The radionuclides are probably the sharpest – they really come on with a bang,” said the Working Group’s chair Jan Zalasiewicz, of the University of Leicester. “But we are spoiled for choice. There are so many signals.”工作组主席、莱斯特大学的简扎拉斯维奇回应:“放射性核素大约是这其中最得意的一个因素—— 放射性核素感叹预示着‘砰’声到来,但是可供选择的因素过于多了,许多因素都对地质产生了极大影响。”Now that the vote has been done, we’ll see a few years of site sampling to figure out the best Global Standard Stratigraphic Age (GSSA) to date the start of the Anthropocene, which will then be presented to the International Commission on Stratigraphy.纪元更改的投票完结后,工作组在未来几年不会利用现场勘测数据计算出来出有最佳的全球标准低层年龄(GSSA),并确认“人类世”的开始日期,预计不会把研究结果送达国际地层委员会。It will then need ratification from the Executive Committee of the International Union of Geological Sciences.随后还必须国际地质科学联合会的继续执行委员会月接纳研究结果。

So it’s not official yet, but Zalasiewicz believes the team has a “pretty good case” to present.所以现在官方只不过还并未月否认人类世的开始,但恰拉斯维奇坚信他的团队提交的案例十分棒。“The significance of the Anthropocene is that it sets a different trajectory for the Earth system, of which we of course are part,” he explained.他说明说道:“‘人类世’的意义在于,它让地球体系步入了一个与众不同的轨道,在这个新纪元里,人类也参予其中。

”“If our recommendation is accepted, the Anthropocene will have started just a little before I was born. We have lived most of our lives in something called the Anthropocene and are just realising the scale and permanence of the change.”“如果我们的建议通过审查,‘人类世’在我出生于前不久就开始了。我们大半辈子都生活在‘人类世’中,而且刚刚意识到地质纪元更改的规模和持久性。”In other words, geologically at least, there will be no denying the influence mankind has had on the planet. And it’s a hard one to put a positive spin upon, no matter how you frame it.换句话来说,最少从地理的看作,我们将无法坚称人类对地球导致的影响。

而且无论我们如何定义都很难将这个影响挽回成正面影响。【mg娱乐官网】。
