Revkin is among those credited with developing the idea that humans, through growing impacts on Earth's climate and other critical systems, are creating a distinct geological epoch, the Anthropocene.[8] He was a member of the "Anthropocene" Working Group from 2010 to 2016. The group is charged by a branch of the International Commission on Stratigraphy with gauging evidence that a formal change in the Geologic Time Scale is justified.[citation needed]
