New Books Terrestrial
paleoenvironmental studies in Beringia The Alaska Quaternary Center has published the proceedings of the 1991 Russian-American
conference on terrestrial paleoenvironmental studies. Copies are available from the AQC
and we are asking western colleagues to pay $10 to help defray printing costs, postage,
and the cost of sending copies to our Russian Order: Alaska Quaternary Center, University of Alaska Museum, 900 Yukon Drive, Suite 358, Fairbanks, AK 99775; 907-474-7758; fax: -5101; fyaqc@aurora.alaska.edu Tectonic Uplift and Climate Change A significant advance in climatological scholarship, Tectonic Uplift and Climate Change is a multidisciplinary effort to summarize the current status of a new theory steadily gaining acceptance in geoscience circles: that long-term cooling and glaciation are controlled by plateau and mountain uplift. Researchers in fields as diverse as geology, geophysics, atmospheric sciences, geochemistry, sedimentation/geomorphology, paleoceanography, and paleobotany, present data that substantiate this hypothesis. Among the areas addressed are most of the dramatic transformations of the Earth's surface in recent geologic history, including: The collision of continents; Changes in the position of the jet stream and westerly winds; The creation of monsoon circulations that deposit heavy rainfall on uplifted terrain; formation of permanent ice sheets over Antarctica and Greenland; The development of sea-ice cover in the Arctic Ocean; Replacement of tree and shrub vegetation by grassland in the subtropics; The onset of periodic fluctuations of massive ice sheets over North America and Eurasia.

Global Warming 125,000 Years Ago The ancient, boreal Eva forest, buried in frozen loess of the subarctic, forms the centerpiece in this evaluation of the time and nature of the environment during an interglaciation warmer than that of the present. This book brings together results of examination of hundreds of loess exposures over the past 50 years, when loess faces were still frozen in gold mining excavations, and new data on the character and age of the deposits from fission-track dating of tephra, paleomagnetism of the loess, thermoluminescence dating of loess, and new radiocarbon dating by liquid scintillation. Dendrochronology studies of trees and 13C/12C isotopic ratios of wood from the Eva forest bed care compared to those from trees of the modern boreal forest. This last interglaciation of 125,000 years ago is demonstrated for the first time to be a period of major erosion of loess and deep and rapid thawing of permafrost, followed by emplacement of the Eva forest bed. During the past 100,000 years, the treeless steppe environment returned and the deposits were refrozen.
