This textbook documents and explains the natural climatic and ecological changes that have occurred during the past 2.6 million years. It also outlines the emergence and global impact of humans during this period. Exploring a wide range of records of climate change, the authors demonstrate the connections between the components of the Earth's climate system, show how the evidence for such change is obtained, and explain some of the problems in collecting and dating proxy climate data.
The book reveals how the rise of humankind coincided with the beginnings of major environmental changes and a mass extinction. It shows that human effects on the world are not merely modern matters but date back a million years or more.

The Great Ice Age documents and explains the natural climatic and palaeoecologic changes that have occurred during the past 2.6 million years, outlining the emergence and global impact of our species during this period. Exploring a wide range of records of climate change, the authors demonstrate the interconnectivity of the components of the Earths climate system, show how the evidence for such change is obtained, and explain some of the problems in collecting and dating proxy climate data.
One of the most dramatic aspects of humanity's rise is that it coincided with the beginnings of major environmental changes and a mass extinction that has the pace, and maybe magnitude, of those in the far-off past that stemmed from climate, geological and occasionally extraterrestrial events. This book reveals that anthropogenic effects on the world are not merely modern matters but date back perhaps a million years or more.

The invited, original chapters by both American and British scientists make this an unusually up-to-date text which attests to the vitality of the present-day concerns of Earth scientists. During the past decade, research by oceanographic geophysicists which has led to the wide acceptance that continents drift about the face of the Earth and to the concept of sea-floor spreading has culminated in an all-embracing theory known as 'plate tectonics'. This theory draws sea-floor spreading, continental drift, crustal structures and world patterns of seismic and volcanic activity together as aspects of one coherent picture. Not only does it explain geophysical evidence and provide a framework within which geological data accumulated over the past two centuries can be fitted; it has also taken the Earth sciences to the stage where they can explain what has happened at the present time, and predict what will happen in the future. In addition, the book covers other currently exciting advances in the Earth sciences such as the accurate dating of rocks by radiometric methods; the Earth's internal composition, magnetic field, heat and internal temperatures; the Chandler Wobble; meteorites; and the Earth-Moon system. Three final chapters illustrate the role of the Earth sciences in society: earthquake prediction and modification, nuclear explosions and earthquakes, and a cautionary yet illuminating account of the Mohole project, which became "perhaps the greatest fiasco in the history of science." Although the book is arranged in a sequence the editors feel is a logical one for straightforward reading, each chapter is self-contained and is introduced by a brief explanatory preface.
