In Faulkner’s work, memories, the dead, and the inescapable circumstance of ancestry are all as present in the room as the characters who fail to overcome them. Geology similarly destroys this priority of the present moment, and as powerfully as any close reading of Absalom, Absalom!

To touch an outcrop of limestone in a highway road cut is to touch a memory, the dead, one’s very heritage, frozen in rock hundreds of millions of years ago—yet still somehow here, present. And because it’s here, it couldn’t have been any other way. This is now our world, whether we like it or not.

The Anthropocene, for Wing, simply states that humans are now a permanent part of this immutable thread of Earth history. What we’ve already done means that there’s no unspoiled Eden to which we could ever return, even if we disappeared from the face of the Earth tomorrow.

that’s what the Anthropocene means. It means: Let us recognize that we have permanently deflected the course of evolution. We have left this pretty much indelible record in sediments that is very comparable to, say, if you were looking around, 100 years after the [dinosaur’s] asteroid

In the particulars—the extent to which humans are destroying and have destroyed the living world, and have dramatically warped the chemistry of the oceans and atmosphere—we agreed.

The difference was perspective. In my essay I framed these planetary injuries in the context of our geologically brief human history. Severe, yes, but at 75 years old (according to Wing’s group) far, far, far too fast,

when the Earth begins its long, long recovery from this strange, technological blitzkrieg in the millions of years to come—and sediment finally begins to stack up in respectable quantities—I presumed that that would be a new

If we wipe ourselves out tomorrow it will still be the Anthropocene a million years from now, even if very little of our works remain.

Where, in my essay, I emphasized the potential transience of civilization, Wing and colleagues on the Anthropocene Working Group emphasize the eternal mark left on the biosphere, whether our civilization is transient or not. This, they argue, is the Anthropocene.

if you want to be a sentient species you have to reckon with the degree to which you have already changed things.”

And that change—whether through tens of thousands of years of human-driven extinctions, our spreading of invasive species across the face of the Earth, converting half of its land surface to farmland, or warming the planet and souring the seas—is undoubtedly profound.

consider the disruption inflicted on the planet by the rise of land plants more than 300 million years earlier. In the Paleozoic, land plants conquered the continents and geoengineered the planet, possibly contributing to, or even causing, at least 10 extinction pulses over 25 million years, including one of the worst mass extinctions in Earth history. Land plants profoundly and permanently altered Earth’s geochemical cycles, underwrote the flourishing of all subsequent life on land, and might have sequestered so much carbon dioxide that they kicked off a 90-million-year ice age.

“What motivates me, I confess, is not my concern for future geologists but my belief that this is philosophically a good thing to do because it makes people think about something that they otherwise wouldn’t think about,” Wing said

Ten million years from now, humans went extinct—give or take a few thousand years—10 million years ago. Huge grazing herbivores and cursorial predators move carbon and nitrogen around the landscape.

Though no one is alive to tell us what epoch it is, these creatures have nevertheless inherited a planet forever diverted by our legacy—as surely, in Faulkner’s words, “as Noah’s grandchildren had inherited the Flood although they had not been there to see the deluge.
