David Grinspoon Quote
Two stratigraphers asked, Is the Anthropocene an Issue of Stratigraphy or Pop Culture? In part, they argued that our presence is as yet too brief a perturbation to merit a named place in the stratigraphic column. The amount of ocean sediments laid down since World War II is less than a millimeter. And, of course, nobody knows how long the Anthropocene will last. That depends crucially on how we, collectively, respond to the novel realization that we’re now in such a time. Our presence, however, is already indelibly inscribed in Earth’s stratigraphic history, and as long as (or whenever) there are geologists, it will be identifiable. Whether or not it becomes official,
