This book features beautiful storytelling and lovely illustrations from Haley Hagerman. 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. The lifespan of Earth can 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. Few of us have any conception of the enormous timescales of our planet’s long history, and this narrow perspective underlies many of the environmental problems we are creating. 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.This month’s Book Club Pick is Timefulness by Marcia Bjornerud, a terrific selection as we approach Earth Day. This compelling book presents a new way of thinking about our place in time, enabling us to make decisions on multigenerational timescales.

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. 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. 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. 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. But spans of hundreds of years-the time a molecule of carbon dioxide resides in the atmosphere-approach the limits of our comprehension.

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. Why an awareness of Earth's temporal rhythms is critical to our planetary survivalįew 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.
