  1. Human and environmental drivers across the IUGS/ICS-approved Holocene ages, along with values for two informal intervals occurring in the last 280 years of the ~11,700-y Holocene history, and the proposed Anthropocene Epoch starting in this paper at 1950 CE. All values shown are interval averages.
