Biologists now suggest that a sixth mass extinction may be under way, given the known species losses over the past few centuries and millennia. Here we review how differences between fossil and modern data and the addition of recently available palaeontological information influence our understanding of the current extinction crisis. Our results confirm that current extinction rates are higher than would be expected from the fossil record, highlighting the need for effective conservation measures.

This fact lies at the heart of the notion of the Anthropocene. Documenting, understanding and responding to the present and future challenges posed by the recent, dramatic changes in the relationship between humans and their environment thus becomes an imperative for human society. This editorial presents the rationale for engaging with the Anthropocene across a wide range of disciplines from engineering and environmental science to the social sciences and humanities. This essentially transdisciplinary engagement requires the establishment of a new journal, The Anthropocene Review, the scope of which is outlined in this editorial.
