Abstract: Global events such as mass extinctions, the onset of Ice Ages, and changes in geochemistry linked with changes in atmospheric chemistry are timeposts in geological strata. In the timeline for Earth history, they allow segmentation of its 4.6 billion year existence into eons, eras, periods, and epochs. As human activity makes its recently initiated yet globally extensive mark that is leading to mass extinctions, changes in atmospheric and marine chemistry, and altering terrestrial features, should a new epoch be declared? Can such an Anthropocene be geologically standardized in strata? Zalasiewicz et al make their case in this article featured in ES&T’s April 1, 2010 print issue recognizing the 40th Anniversary of Earth Day.
