Another autumn, more fires, more refugees and incinerated homes. For California, flames have become the colors of fall.
Free-burning fire is the proximate provocation for the havoc, since its ember storms are engulfing landscapes. But in the hands of humans, combustion is also the deeper cause. Modern societies are burning lithic landscapes - once-living biomass now fossilized into coal, gas and oil - which is aggravating the burning of living landscapes.
Now the sources overload the sinks: Too much fossil biomass is burned to be absorbed within ancient ecological bounds. Fuels in the living landscape pile up and rearrange themselves. The climate is unhinged. When flame returns, as it must, it comes as wildfire.
Welcome to the Pyrocene
Widen the aperture a bit, and we can envision Earth entering a fire age comparable to the ice ages of the Pleistocene, complete with the pyric equivalent of ice sheets, pluvial lakes, periglacial outwash plains, mass extinctions, and sea level changes. It's an epoch in which fire is both prime mover and principal expression.
.Add up all the effects, direct and indirect — the areas burning, the areas needing to be burned, the off-site impacts with damaged watersheds and airsheds, the unraveling of biotas, the pervasive power of climate change, rising sea levels, a mass extinction, the disruption of human life and habitats — and you have a pyrogeography that looks eerily like an ice age for fire. You have a Pyrocene. The contours of such an epoch are already becoming visible through the smoke.
And as the article says, if you doubt it, just ask California.
