The Last Maximum Ice Extent and Subsequent Deglaciation of the Pyrenees: an Overview of Recent Research
Cuadernos de Investigación Geográfica 2015 Nº 41 (2) pp. 359-387 ISSN 0211-6820 DOI: 10.18172/cig.2708 © Universidad de La Rioja THE LAST MAXIMUM ICE EXTENT AND SUBSEQUENT DEGLACIATION OF THE PYRENEES: AN OVERVIEW OF RECENT RESEARCH M. DELMAS Université de Perpignan-Via Domitia, UMR 7194 CNRS, Histoire Naturelle de l’Homme Préhistorique, 52 avenue Paul Alduy 66860 Perpignan, France. ABSTRACT. This paper reviews data currently available on the glacial fluctuations that occurred in the Pyrenees between the Würmian Maximum Ice Extent (MIE) and the beginning of the Holocene. It puts the studies published since the end of the 19th century in a historical perspective and focuses on how the methods of investigation used by successive generations of authors led them to paleogeographic and chronologic conclusions that for a time were antagonistic and later became complementary. The inventory and mapping of the ice-marginal deposits has allowed several glacial stades to be identified, and the successive ice boundaries to be outlined. Meanwhile, the weathering grade of moraines and glaciofluvial deposits has allowed Würmian glacial deposits to be distinguished from pre-Würmian ones, and has thus allowed the Würmian Maximum Ice Extent (MIE) –i.e. the starting point of the last deglaciation– to be clearly located. During the 1980s, 14C dating of glaciolacustrine sequences began to indirectly document the timing of the glacial stades responsible for the adjacent frontal or lateral moraines. Over the last decade, in situ-produced cosmogenic nuclides (10Be and 36Cl) have been documenting the deglaciation process more directly because the data are obtained from glacial landforms or deposits such as boulders embedded in frontal or lateral moraines, or ice- polished rock surfaces. -
Medieval Warm Period in South America
M EDIEVAL WARM PERIOD IN OUTH MERICA S A SPPI & CO2SCIENCE ORIGINAL PAPER ♦ September 4, 2013 MEDIEVAL WARM PERIOD IN SOUTH AMERICA Citation: Center for the Study of Carbon Dioxide and Global Change. "Medieval Warm Period in South America.” Last modified September 4, 2013. http://www.co2science.org/subject/m/summaries/mwpsoutham.php. Was there a Medieval Warm Period anywhere in addition to the area surrounding the North Atlantic Ocean, where its occurrence is uncontested? This question is of utmost importance to the ongoing global warming debate, since if there was, and if the locations where it occurred were as warm then as they are currently, there is no need to consider the temperature increase of the past century as anything other than the natural progression of the persistent millennial- scale oscillation of climate that regularly brings the earth several-hundred-year periods of modestly higher and lower temperatures that are totally independent of variations in atmospheric CO2 concentration. Hence, this question is here considered as it applies to South America, a region far removed from where the existence of the Medieval Warm Period was first recognized. Cioccale (1999) assembled what was known at the time about the climatic history of the central region of the country over the past 1400 years, highlighting a climatic "improvement" that began some 400 years before the start of the last millennium, which ultimately came to be characterized by "a marked increase of environmental suitability, under a relatively homogeneous climate." And as a result of this climatic amelioration that marked the transition of the region from the Dark Ages Cold Period to the Medieval Warm Period, Cioccale reported that "the population located in the lower valleys ascended to higher areas in the Andes," where they remained until around AD 1320, when the transition to the stressful and extreme climate of the Little Ice Age began. -

Every day the news media is filled with dire predictions of impending disastersdcatastrophic melting of the Antarctic and Greenland ice sheets, drowning of major cities from sea level rise, drowning of major portions of countries, droughts, severe water shortages, no more snow, more extreme weather events (hurricanes, tor- nadoes), etc. With no unequivocal, cause-and-effect, tangible, physical evidence that increasing CO2 caused this most recent global warming, adherents of this ideology have had to rely on computer models that have proven to be unreliable. -

An Archaeological Inventory of Alamance County, North Carolina
AN ARCHAEOLOGICAL INVENTORY OF ALAMANCE COUNTY, NORTH CAROLINA Alamance County Historic Properties Commission August, 2019 AN ARCHAEOLOGICAL INVENTORY OF ALAMANCE COUNTY, NORTH CAROLINA A SPECIAL PROJECT OF THE ALAMANCE COUNTY HISTORIC PROPERTIES COMMISSION August 5, 2019 This inventory is an update of the Alamance County Archaeological Survey Project, published by the Research Laboratories of Anthropology, UNC-Chapel Hill in 1986 (McManus and Long 1986). The survey project collected information on 65 archaeological sites. A total of 177 archaeological sites had been recorded prior to the 1986 project making a total of 242 sites on file at the end of the survey work. Since that time, other archaeological sites have been added to the North Carolina site files at the Office of State Archaeology, Department of Natural and Cultural Resources in Raleigh. The updated inventory presented here includes 410 sites across the county and serves to make the information current. Most of the information in this document is from the original survey and site forms on file at the Office of State Archaeology and may not reflect the current conditions of some of the sites. This updated inventory was undertaken as a Special Project by members of the Alamance County Historic Properties Commission (HPC) and published in-house by the Alamance County Planning Department. The goals of this project are three-fold and include: 1) to make the archaeological and cultural heritage of the county more accessible to its citizens; 2) to serve as a planning tool for the Alamance County Planning Department and provide aid in preservation and conservation efforts by the county planners; and 3) to serve as a research tool for scholars studying the prehistory and history of Alamance County. -
Oxygen Isotope Evidence for Paleoclimate Change During The
PALEOCLIMATE RECONSTRUCTION IN NORTHWEST SCOTLAND AND SOUTHWEST FLORIDA DURING THE LATE HOLOCENE Ting Wang A dissertation submitted to the faculty of the University of North Carolina at Chapel Hill in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the Department of Geological Sciences. Chapel Hill 2011 Approved by: Dr. Donna M. Surge Dr. Joseph G. Carter Dr. Jose A. Rial Dr. Justin B. Ries Dr. Karen J. Walker © 2011 Ting Wang ALL RIGHTS RESERVED ii ABSTRACT TING WANG: Paleoclimate Reconstruction in Northwest Scotland and Southwest Florida during the Late Holocene (Under the direction of Dr. Donna M. Surge) The study reconstructed seasonal climate change in mid-latitude northwest Scotland during the climate episodes Neoglacial (~3300-2500 BP) and Roman Warm Period (RWP; ~2500-1600 BP) and in subtropical southwest Florida during the latter part of RWP (1-550 AD) based on archaeological shell accumulations in two study areas. In northwest Scotland, seasonal sea surface temperature (SST) during the Neoglacial and RWP was estimated from high-resolution oxygen isotope ratios (δ18O) of radiocarbon-dated limpet (Patella vulgata) shells accumulated in a cave dwelling on the Isle of Mull. The SST results revealed a cooling transition from the Neoglacial to RWP, which is supported by earlier studies of pine pollen in Scotland and European glacial events and also coincident with the abrupt climate deterioration at 2800-2700 BP. The cooling transition might have been driven by decreased solar radiation and weakened North Atlantic Oscillation (NAO) conditions. In southwest Florida, seasonal-scale climate conditions for the latter part of RWP were reconstructed by using high-resolution δ18O of archaeological shells (Mercenaria campechiensis) and otoliths (Ariopsis felis). -

A Possible Late Pleistocene Impact Crater in Central North America and Its Relation to the Younger Dryas Stadial
A POSSIBLE LATE PLEISTOCENE IMPACT CRATER IN CENTRAL NORTH AMERICA AND ITS RELATION TO THE YOUNGER DRYAS STADIAL SUBMITTED TO THE FACULTY OF THE UNIVERSITY OF MINNESOTA BY David Tovar Rodriguez IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF SCIENCE Howard Mooers, Advisor August 2020 2020 David Tovar All Rights Reserved ACKNOWLEDGEMENTS I would like to thank my advisor Dr. Howard Mooers for his permanent support, my family, and my friends. i Abstract The causes that started the Younger Dryas (YD) event remain hotly debated. Studies indicate that the drainage of Lake Agassiz into the North Atlantic Ocean and south through the Mississippi River caused a considerable change in oceanic thermal currents, thus producing a decrease in global temperature. Other studies indicate that perhaps the impact of an extraterrestrial body (asteroid fragment) could have impacted the Earth 12.9 ky BP ago, triggering a series of events that caused global temperature drop. The presence of high concentrations of iridium, charcoal, fullerenes, and molten glass, considered by-products of extraterrestrial impacts, have been reported in sediments of the same age; however, there is no impact structure identified so far. In this work, the Roseau structure's geomorphological features are analyzed in detail to determine if impacted layers with plastic deformation located between hard rocks and a thin layer of water might explain the particular shape of the studied structure. Geophysical data of the study area do not show gravimetric anomalies related to a possible impact structure. One hypothesis developed on this works is related to the structure's shape might be explained by atmospheric explosions dynamics due to the disintegration of material when it comes into contact with the atmosphere.
