“A Billion Black Anthropocenes or None”
K. Yusoff, 2019, University of Minnesota Press.
Page to purchase e-pub.
Kathryn Yusoff examines how the grammar of geology is foundational to establishing the extractive economies of subjective life and the earth under colonialism and slavery. She initiates a transdisciplinary conversation between black feminist theory, geography, and the earth sciences, addressing Continue reading
Scaling Deep Time: Encountering the History of Climate Change
The historian has rarely lived through the events of past times that he describes. He has not seen them with his own eyes; rather, he describes them on the basis of the documents at hand, whether these are the yellowed leaves of old codices and parchments, or the brown fossil leaves Continue reading
Earth Plasticity and Plasticity of Perception
One of my earliest memories as a freshman at UCLA took place in the front row of a cavernous, wood-paneled lecture hall equipped with a black-topped resin demonstration table. The class was Introductory Geology, and the professor a bearded, pony-tailed free spirit giddy with the anticipation of Continue reading
Pondering a diorama to perceive the Anthropocene
“This sprawling epic is as lively as a natural history museum diorama.” (Stephanie Zacharek, review of “10,000 BC”)
Perceiving means to become conscious of, to realize, to understand, to grasp. Natural history museums strive to enable the public to perceive, commonly in re-creations of past worlds. Who hasn’t gazed over a diorama of the Carboniferous Period, for example, Continue reading

An Age of Trump in the Anthropocene Epoch?
Stratigraphy is the science of rock strata; in geological terms, this translates to the science of time. But what IS time? Difficult to define, for certain, but most of us can agree that it marks the passage of events. We experience the passage of Continue reading
THIS POST IS PART OF OUR ANTHROPOCENE BIOSPHERE PROJECT–A SERIES OF POSTS ON ERLE ELLIS’ ‘ECOLOGY IN AN ANTHROPOGENIC BIOSPHERE‘ (ECOLOGICAL MONOGRAPHS, 85/3 (2015))
In preparation for Erle Ellis’ visit to OU’s campus in April, I’ve spent some time considering topics I hope we can address during his visit. Continue reading
“The Global Carbon Cycle: A Test of Our Knowledge of Earth as a System”
The Dust of Civilization
THIS POST IS PART OF THE SOCIAL MEDIA IN THE ANTHROPOCENE PROJECT—SEE THIS DESCRIPTION OF OUR SUBMISSION.
In an earlier post, I emphasized the strong link between the origins of agriculture and the positions of loess (loosely “dust”) regions—arguing in essence that, from dust arises life. If loess bestows habitation and habitability, then loess paved the way for Continue reading

Earth, Life, and Time: What is Natural?
Life on Earth has always altered its environment.1 “Deep” time records major shifts in atmospheric composition, for example, as life evolved photosynthesis, leading to a massive transfer of CO2 from the atmosphere to the biosphere. Given this, is the large-scale injection into the atmosphere of anthropogenically released carbon a completely natural consequence of biotic activity?
Atmospheric levels of CO2 have always changed, attributable in part to life — and well before the influence of humans. On geologic time scales such fluctuation results from Continue reading
