Antropocén začal zdokonalením parního stroje v roce 1784 a masivním využíváním fosilních paliv, ale různí autoři posunují jeho počátek dále do minulosti či naopak do minulého století, třeba do neolitu, do vzestupu římského impéria či na konec druhé světové války.

2016 March 3, Václav Cílek, “Antropocén – velké zrychlení světa”, in Vesmír, volume 95, number 3:

Anthropocene started with the improvement of steam engine in 1784 and massive exploitation of fossil fuels, but various authors move its beginning farther into the past or on the contrary to the past century, for example into the Neolithic, to the rise of the Roman Empire or to the end of the Second World War.
