• Sommario/riassunto: Examines the various forms of evidence used to establish the history and scale of environmenal changes during the Quaternary. The evidence is extremely diverse, ranging from landforms and sediments to fossil assemblages and isotope ratios, bringing the book fully up to date since its last publication.
