In January 2015 , 26 of the 38 members of the International Anthropocene Working Group published a paper suggesting the Trinity test on 16 July 1945 as the starting point of the proposed new epoch .

Other scholars point to the diachronous character of the physical strata of the Anthropocene , arguing that onset and impact are spread out over time , not reducible to a single instant or date of start
