Why an awareness of Earth’s temporal rhythms is critical
to our planetary survival
Few of us have any conception of the enormous timescales in our
planet’s long history, and this narrow perspective underlies many
of the environmental problems we are creating for ourselves. The
passage of nine days, which is how long a drop of water typically
stays in Earth’s atmosphere, is something we can easily grasp. But
spans of hundreds of years—the time a molecule of carbon dioxide
resides in the atmosphere—approach the limits of our comprehension.
Our everyday lives are shaped by processes that vastly predate us,
and our habits will in turn have consequences that will outlast us
by generations. Timefulness reveals how knowing
the rhythms of Earth’s deep past and conceiving of time as a
geologist does can give us the perspective we need for a more
sustainable future.
Marcia Bjornerud shows how geologists chart the planet’s past,
explaining how we can determine the pace of solid Earth processes
such as mountain building and erosion and comparing them with the
more unstable rhythms of the oceans and atmosphere. These
overlapping rates of change in the Earth system—some fast, some
slow—demand a poly-temporal worldview, one that Bjornerud calls
“timefulness.” She explains why timefulness is vital in the
Anthropocene, this human epoch of accelerating planetary change,
and proposes sensible solutions for building a more time-literate
society.
This compelling book presents a new way of thinking about our place
in time, enabling us to make decisions on multigenerational
timescales. The lifespan of Earth may seem unfathomable compared to
the brevity of human existence, but this view of time denies our
deep roots in Earth’s history—and the magnitude of our effects on
the planet.
Marcia Bjornerud is professor of geology and environmental studies at Lawrence University. She is the author of Reading the Rocks: The Autobiography of the Earthand a contributing writer for Elements, the New Yorker’s science and technology blog. She lives in Appleton, Wisconsin.
