Last week, a panel of scientists voted in favor of classifying the age we are living in as a new geological epoch—the “Anthropocene”—after reviewing available evidence on the issue.上星期,一组生物学家在稿子了目前直接证据以后,网络投票赞成将大家所在的时期区别为一个新的地质时代——人类世。Since it was first formally proposed more than a decade ago, the name has been the subject of intense debate among experts. But the 34-member Anthropocene Working Group (AWG) chaired by Jan Zalasiewicz, of the University of Leicester in the UK, decided that humans are having such a profound impact on our planet that the term is a valid one, Nature.com reported.自打十多年前这一专业术语初次被月明确指出至今,权威专家们依然因此进行日趋激烈的争论。据自然界杂志期刊报道,人类世协作组(AWG)确定,人们对地球造成了这般深刻影响的危害,这一各不相同是合情合理的。


人类世协作组由美国莱斯特大学的珍·扎拉塞维奇担任现任主席,总共34名组员。The International Commission on Stratigraphy (ICS)—which oversees the geological time chart—has yet to approve the new term. But in the wake of the latest vote, the AWG will submit a formal proposal to the ICS by 2021 in a bid to formally define our current era, where mankind is the dominant influence on the planets climate and environment.部门管理地质学时刻表的国际性地层学联合会(ICS)仍未批准后这一新的专业术语。但在近期一次网络投票以后,AWG将在二零二一年以前向ICS提交一份月提案,以月界定大家当今的时期,也就是人们对地球气侯和自然环境造成核心危害的时期。The vote saw 29 members of the AWG support not only the new Anthropocene designation but also a favored start date—the mid-twentieth century. Various starting points have been proposed for the Anthropocene era ranging from the beginnings of agriculture more than 10,000 years ago to the first atomic bomb blast in 1945 that spread radioactive debris around the world—traces of which can still be detected in the planets soil and glaciers.在此次网络投票中,29名AWG组员不但抵制新的人类世取名,并且还抵制以二十世纪中后期做为人类世的刚开始。

针对人类世的起点有各有不同的提议,有提议以一万多年前农耕时代的刚开始为起点,也有提议以1940年第一颗核弹发生爆炸事故为起点,这一次发生爆炸事故将放射性残片散布到世界各国,现如今在地球的土壤层和冰河中仍然能够检验到放射性残片的印痕。Most scientists who support the Anthropocene designation favor the later start date, and the AWG panel agreed based on the fact that rapid population growth and industrialization in the mid-twentieth century—which led to greater natural resource use and greenhouse gas emissions—mark a “Great Acceleration” on our species impact on the planet.大部分抵制人类世取名的生物学家更为偏重于以1940年为起点。因为二十世纪中期人口数量的持续增长及现代化耗费了更为多的生态资源并造成了更为多的空气污染物,意味着人们对地球种群的危害“大加速”,AWG抵制这一起复時间。“The Anthropocene works as a geological unit of time, process and strata,” Zalasiewicz told Nature.com. “It is distinguishable. It is distinctive.”扎拉塞维奇对他说自然界杂志期刊讲到:“人类世是時间、全过程和地质构造的地质学企业。


它是分得清其他,也是特有的。”The next step for the AWG is to identify a definitive geological marker known as a “golden spike” to include in their formal proposal. This is an internationally recognized reference point in rock layers which scientists use to define the boundaries between geological epochs. The current epoch, known as the Holocene, began around 11,700 years ago at the end of the last glacial period.AWG的下一步工作是确定一个称之为“金钉”的权威性地质学标示,并将其划归月提案中。这是一个国际性广泛认为的岩石层测量点,专家用它来界定地质时代中间的界限。

如今这一称之为全新世的时期约始自11700年前的最后一个冰河时期的后期。The panel outlined ten golden spike candidates, which could be used to differentiate the Holocene from the Anthropocene, including a cave in northern Italy and a lake in China. They are also considering whether to use traces of radioactive debris—originating from the first nuclear tests—in order to bolster their claim.该工作组列出了十个金钉备选地址,他们能够用于区别全新世和人类世,还包含西班牙北边的一个洞窟和我国的一个湖水。她们仍在充分考虑否用以来源于第一次核实验的放射性残片印痕来抵制她们的认为。
