The Quaternary Ice Age is a comprehensive scientific book written by William Bourke Wright and first published in 1914. The book is focused on the geological history of the earth during the Quaternary period, which spans from 2.6 million years ago to the present day. Wright's work is based on extensive research and analysis of geological evidence, including the study of sedimentary rocks, fossils, and ice cores. He explores the various theories and hypotheses that have been proposed to explain the causes and effects of the Quaternary Ice Age, including changes in the earth's orbit, solar radiation, and atmospheric composition.The book is divided into several chapters, each of which focuses on a different aspect of the Quaternary Ice Age. Wright begins by providing an overview of the period and its significance in the history of the earth. He then delves into the various types of evidence that have been used to study the Ice Age, including glacial deposits, sea-level changes, and the distribution of flora and fauna.Wright also discusses the impact of the Ice Age on human evolution and migration, as well as the role of climate change in shaping the earth's ecosystems. He concludes by examining the potential implications of ongoing climate change and the risks posed by rising sea levels and other environmental threats.Overall, The Quaternary Ice Age is a seminal work of geological science that provides a detailed and insightful exploration of one of the most significant periods in the earth's history.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
