Modern atmospheric CO2 increases, driven mainly by human activities, have led to a marked increase in global mean temperatures and rates of sea-level rise in part through melting of ice-sheets. (© C N Waters).

The Anthropocene Working Group (AWG) is the body tasked to propose a formal definition for the Anthropocene as a geological time unit. Join us at the EGU2021 General Assembly on Wednesday 28th April at 14:15-15:00 CEST for a series of presentations on the Anthropocene in session SSP2.6. The Anthropocene concept Geologists cope with the enormity of 4.5 billion years of Earth history by divid ...[Read More]
