Harriet Mercer writes about the ways historians incorporate geological and natural history evidence in the Anthropocene in an article for History Workshop Journal. "By embracing the archives of the Anthropocene alongside their more traditional sets of sources, historians can help ensure that that atmospheric data does not get reified into decontextualised truths about past societies. Historians can add the context and contingency that are at the core of our craft." Harriet was a participant in the 2018 Environmental History PhD workshop, led by Tom Griffiths, Libby Robin, Heather Goodall and Christof Mauch, and is a doctorate student at the University of Oxford’s Centre for Global History.
