Revolutions that Made the Earth

by Tim Lenton, Andrew Watson

Overview

The Earth that sustains us today was born out of a few remarkable, near-catastrophic revolutions, started by biological innovations and marked by global environmental consequences. The revolutions have certain features in common, such as an increase in the complexity, energy utilization, and information processing capabilities of life. This book describes these revolutions, showing the fundamental interdependence of the evolution of life and its non-living environment. We would not exist unless these upheavals had led eventually to 'successful' outcomes - meaning that after each one, at length, a new stable world emerged.

The current planet-reshaping activities of our species may be the start of another great Earth system revolution, but there is no guarantee that this one will be successful. This book explains what a successful transition through it might look like, if we are wise enough to steer such a course.

This book places humanity in context as part of the Earth system, using a new scientific synthesis to illustrate our debt to the deep past and our potential for the future.

About the Author

Tim Lenton is a Professor at the University of Exeter. His research focuses on understanding the behaviour of the Earth as a whole system, especially through the development and use of Earth system models. After gaining a BA in Natural Sciences at Cambridge University, he investigated what regulates the nutrient balance of the ocean and the oxygen content of the atmosphere as a PhD student of Andrew Watson. He also worked closely with James Lovelock developing the Gaia theory and trying to reconcile it with evolutionary theory. Moving to the Centre for Ecology and Hydrology in Edinburgh, he focused on understanding the feedbacks between the carbon cycle and the Earth's climate. Having returned to the University of East Anglia in 2004, his work identifying climate tipping points won the Times Higher Education Award for Research Projects of the Year 2008. He holds a number of other awards and fellowships.

Andrew Watson holds a Royal Society Research Professorship at the University of East Anglia. His career has spanned planetary and atmospheric sciences, oceanography, and climate, giving him a strong interest in the evolution of the Earth system as a whole. After obtaining a BSc in physics from Imperial College, he investigated the history of oxygen in Earth's atmosphere as a PhD student of James Lovelock. He worked on NASA's Pioneer Venus space mission at the University of Michigan. Returning to England and the marine research laboratories in Plymouth, he developed a new method of tracing large scale water movements. He became a professor at the University of East Anglia in 1996, was elected a Fellow of the Royal Society in 2003, and became a Royal Society Research Professor in 2009. He holds a number of other fellowships and awards.

Editorial Reviews

"This is an up-to-date version of such integrated views of Earth history as a time series of stable environmental states, or steps, each of which is punctuated by biologically induced 'revolutions'... This work may become one of the better avenues for the intelligent undergraduate to grasp the scientific version of the Gaia hypothesis... Highly recommended." —CHOICE
