The #Anthropocene epoch has definitely begun.
The evidence is overwhelming: earth entered a new geological epoch in about 1950
The AWG will now shift its focus to identifying a global “signal” that coincides with the change. Ten of the AWG’s members favor using plutonium fallout from nuclear tests as the signal, but there are many other possibilities. Once a signal is agreed on, they will determine a “golden spike” ( properly, a “Global Boundary Stratotype Section and Point”) — an actual location in rock, sediment or ice strata, somewhere on earth, that would physically define the onset of the new epoch.
