On Unease and Discomfort About the Anthropocene
Earth's Future, Volume 14, Issue 2, February 2026.Abstract The proposal for a formal inclusion of the Anthropocene as a new unit of the Geologic Time Scale (GTS) was rejected in part on the grounds that it would sit uncomfortably in the GTS. The durations of all GTS units tend to become shorter toward the present. The proposed Anthropocene epoch and Crawfordian age fit that trend comfortably.
