A

according to the IPCC, “a proposed new geological epoch resulting from significant
human-driven changes to the structure and functioning of the Earth System, including
the climate system”182; in March of 2024, the International Union of Geological Sciences rejected a proposal to formally name the Anthropocene as a new geological epoch, but noted that the term will “continue to be used not only by Earth and environmental scientists but also by social scientists, politicians and economists as well as by the public at large” and “will remain an invaluable descriptor of human impact on the Earth system.”183
