In 2002, Noble Laureate Paul Crutzen wrote in the journal Nature:
“For the past three centuries, the effects of humans on the global environment have escalated.
Because of these anthropogenic emissions of carbon dioxide, global climate may depart
significantly from natural behaviour for many millennia to come. It seems appropriate to assign
the term ‘Anthropocene’ to the present, in many ways human-dominated, geological epoch,
supplementing the Holocene — the warm period of the past 10–12 millennia. The Anthropocene
could be said to have started in the latter part of the eighteenth century, when analyses of air
trapped in polar ice showed the beginning of growing global concentrations of carbon dioxide
and methane. This date also happens to coincide with James Watt’s design of the steam engine
in 1784.”
