However, after several rounds of voting by the AWG, Crawford Lake, near Toronto, was selected.

然而，在人类世工作组的几轮投票后，多伦多附近的克劳福德湖被选定为候选地。

In 2016 the Anthropocene Working Group (awg), an appendage of the International Union of Geological Sciences (iugs), voted in favour of adopting it in principle.

2016年，国际地质科学联合会的附属机构，人类世工作组投票赞成在原则上采用这一标准。

The isotopes that the awg have in mind have half-lives of 6,500 and 24,000 years, meaning almost all the plutonium will be gone within 200,000 years.

人类世工作组所考虑的同位素的半衰期分别为6500年和24000年，这意味着几乎所有的钚都将在20万年内消失。

The AWG will present a dossier of evidence hoping to convince the voting bodies that the Anthropocene does represent a planetary change that requires a new geological time period.

AWG 将提交一份证据档案，希望能说服投票机构，人类世确实代表了一个需要一个新的地质时期的行星变化。

" There is compelling evidence globally of a massive shift, a tipping point, in the Earth's system, " said Prof Francine McCarthy, a geologist at Brock University, Canada, and AWG member.

加拿大布洛克大学的地质学家、AWG成员弗朗辛·麦卡锡教授说：“全球有令人信服的证据表明，地球系统发生了巨大的变化，出现了一个临界点。”

Indeed, the awg has proposed that the subsequent spike in plutonium-an element which was vanishingly rare before the atomic age-should serve as the " primary marker" for the beginning of the Anthropocene.

事实上，人类世工作组已经提出，钚(一种在原子时代之前非常罕见的元素)随后的峰值应该作为人类世开始的“主要标志”。

(For instance, the start of the Edicarian period, 635m years ago, is defined by a visible change in a band of exposed rocks in southern Australia.) The awg's announcement marked the end of a years-long search for a suitable marker for the Anthropocene.

(例如，6.35亿年前伊迪卡利亚时期的开始，是由澳大利亚南部裸露岩石带的明显变化确定的。)人类世工作组的宣布标志着长达数年的寻找人类世合适标志工作的结束。
