The Anthropocene epoch: have we entered a new phase of planetary history? By Nicola Davison
From the pragmatic stratigraphic perspective, no marker is as distinct, or more globally synchronous, than the radioactive fallout from the use of nuclear weapons that began with the US army’s Trinity test in 1945. Since the early 1950s, this memento of humankind’s darkest self-destructive impulses has settled on the Earth’s surface like icing sugar on a sponge cake. Plotted on a graph, the radioactive fallout leaps up like an explosion. Zalasiewicz has taken to calling it the “bomb spike”.
he slowly realized that the sciences were not a way to limit violence but to fuel it. He decided to hear and to feel this terrible earth shaking tremor travelling from Hiroshima, the only date in history that he takes as a real turning-point; the earth has been shaking ever since….

It was February 2000 and the Nobel laureate Paul Crutzen was sitting in a meeting room in Cuernavaca, Mexico, stewing quietly. Five years earlier, Crutzen and two colleagues had been awarded the Nobel prize in chemistry for proving that the ozone layer, which shields the planet from ultraviolet light, was thinning at the poles because of rising concentrations of industrial gas. Now he was attending a meeting of scientists who studied the planet’s oceans, land surfaces and atmosphere. As the scientists presented their findings, most of which described dramatic planetary changes, Crutzen shifted in his seat. “You could see he was getting agitated. He wasn’t happy,” Will Steffen, a chemist who organised the meeting, told me recently.

What finally tipped Crutzen over the edge was a presentation by a group of scientists that focused on the Holocene, the geological epoch that began around 11,700 years ago and continues to the present day. After Crutzen heard the word Holocene for the umpteenth time, he lost it. “He stopped everybody and said: ‘Stop saying the Holocene! We’re not in the Holocene any more,’”..
