RESUMENEste estudio analiza los impactos de sequías e inundaciones en el Bajo Segura durante la primera mitad del siglo xviii. Apoyándonos en trabajos precedentes, hemos tratado de aportar datos inéditos sobre las repercusiones de los riesgos naturales. Para ello hemos analizado los Libros de Actas Capitulares del cabildo eclesiástico oriolano, custodiados en el Archivo Diocesano de Orihuela. El resultado es un recorrido cronológico por los contrastes climáticos del marco geográfico, acentuando los episodios hidrometeorológicos más extremos y delimitando en el tiempo los períodos de mayor irregularidad. Igualmente nos aproximamos a la relación entre el clima y el devenir histórico de las vulnerables sociedades preindustriales desde la perspectiva de la referida institución religiosa. Para dotar de mayor dimensión al estudio, nos acercaremos sucintamente a las fundamentales rogativas pro pluvia y pro serenitate, y cómo estas evolucionaron entre 1700 y 1750.PALABRAS CLAVEOrihuela, Pequeña Edad del Hielo, sequías, inundaciones, riadas, rogativas. TITLEFrom droughts to fl oods: high climatic variability cases from the ecclesiastical sources of Orihuela (1700-1750)ABSTRACTThis study analyzes the droughts and floods impacts in Bajo Segura during the first half of the 18th century. Supporting us in the precedents works, we tried to provide unpublished data on the repercussions of natural risks. For this purpose, we have turned over and analyzed the Chapter Record Books of the Oriolan Ecclesiastical Chapter, kept in the Diocesan Archives of Orihuela (A.D.O). The result is a chronological journey through the climatic contrasts of the geographical frame, accentuating the most extreme hydrometeorological episodes and delimiting periods of greatest irregularity over time. We also approach the relationship between the climate and the historical evolution of the vulnerable pre-industrial societies from the aforementioned religious institution perspective. To give a greater dimension to the study, we will briefly approach the fundamental rogation pro pluvia and pro serenitate, and how they evolved between 1700 and 1750.KEY WORDSOrihuela, Little Ice Age, droughts, floods, stream, rogation.

Abstract. We present results of analysis of biological (diatoms and ostracodes) and non-biological (Ti, Ca / Ti, total inorganic carbon, magnetic susceptibility) variables from an 8.8 m long, high-resolution (~ 20 yr sample−1) laminated sediment sequence from Lake Santa María del Oro (SMO), western Mexico. This lake lies at a sensitive location between the dry climates of northern Mexico, under the influence of the North Pacific subtropical high-pressure cell and the moister climates of central Mexico, under the influence of the seasonal migration of the intertropical convergence zone and the North American monsoon (NAM). The sequence covers the last 2000 years and provides evidence of two periods of human impact in the catchment, shown by increases in the diatom Achnanthidium minutissimum. The first from AD 100 to 400 (Early Classic) is related to the shaft and chamber tombs cultural tradition in western Mexico, and the second is related to Post-Classic occupation from AD 1100 to 1300. Both periods correspond to relatively wet conditions. Three dry intervals are identified from increased carbonate and the presence of ostracodes and aerophilous Eolimna minima. The first, from AD 500 to 1000 (most intense during the late Classic, from AD 600 to 800), correlates with the end of the shaft and chamber tradition in western Mexico after ca. AD 600. This late Classic dry period is the most important climatic signal in the Mesoamerican region during the last 2000 years, and has been recorded at several sites from Yucatan to the Pacific coast. In the Yucatan area, this dry interval has been related with the demise of the Maya culture at the end of the Classic (AD 850 to 950). The last two dry events (AD 1400 to 1550 and 1690 to 1770) correspond with the onset of, and the late, Little Ice Age, and follow largely the Spörer and Maunder minima in solar radiation. The first of these intervals (AD 1400 to 1550) shows the most intense signal over western Mexico; however this pattern is different at other sites. Dry/wet intervals in the SMO record are related with lower/higher intensity of the NAM over this region, respectively.

The Sidi El Hani Wetland is located in Eastern Tunisia. It represents the natural outlet of an endorheic system, Mechertate-Chrita-Sidi El Hani, and it collects all the eroded sediment from this watershed. In this chapter, the visual core description focused on three reference sandy bands and on the concept of grey scale variability in order to infer the clay pan response to the climatic variability and erosion during the last two millennia. First, in the uppermost part, the stage Warming Present (WP) stretches from (1954-80= 1874) to 1993, i.e. ≈120yrs; the establishment of modern conditions is characterized by stable conditions with high grey scale. Added to a small salt crust, this period is dominated by a clayey sedimentation. Second, the stage C4 is called the Late Little Ice Age (Late LIA); it stretches between the 80yrBP and 400yrBP, i.e., 320yrs. It is characterized by intermediate GS values; the clayey sedimentation makes up the twofold and threefold laminates. Based on laser granulometer, the genetic approach shows the interplay of eolian and hydraulic erosion.

The volume of debris in the left-lateral, Little Ice Age (LIA:AD1550–1850) moraine of the Feegletscher, Valais, Switzerland was compared with the actual volume being transported currently by the glacier. The latter is smaller by a factor of about two. In Tröllaskagi, north Iceland, a surface cover of debris on top of a very slow moving glacier ice mass (glacier noir, rock glacier) has been dated by lichenometry. The age of the oldest part is commensurate with LIA moraines in the area. Knowing the volume of debris of a given age allows an estimate of the debris supply to the glacier in a given time. Again, there appears to have been a significant reduction in debris to the glacier since the turn of the 19th century. Debris input in the early LIA seems to have been particularly copious and this may be important in the formation of some glacier depositional forms such as rock glaciers.

Abstract. The maximum glacier extent during the "Little Ice Age" (mid 18th century AD) in Jotunheimen, southern Norway, was mapped using remote sensing techniques. Interpretation of existing glaciochronological studies, analysis of geomorphological maps, and own GPS-field measurements were applied for validation of the mapping. The length of glacier centrelines and other inventory data were determined using a Geographical Information System (GIS) and a Digital Elevation Model. "Little Ice Age" maximum extent for a total of 233 glaciers comprising an overall glacier area of about 290 km2 was mapped. Mean length of the centreline was calculated to 1.6 km. Until AD 2003, the area and length shrank by 35% and 34%, respectively, compared with the maximum "Little Ice Age" extent.

“Power of Attorney in Oaxaca, Mexico: Native People, Legal Culture, and Social Networks” is an ongoing digital research project that constructs a geography of indigenous legal culture through digital maps and visualizations. The Power of Attorney website analyzes relationships among people, places, and courts that were created by the granting of power attorney, a notarial procedure common across the Spanish empire. The primary actors in this story are indigenous individuals, communities, and coalitions of communities in the diocese of Oaxaca, Mexico, and the legal agents who represented them, some of whom were untitled indigenous scribes, and others, titled lawyers and legal agents of Spanish descent. The relationship between indigenous litigants and their legal agents created social networks and flows of knowledge and power at a variety of scales, some local and some transatlantic, whose dimensions changed over time. The pilot for the project focuses on the district of Villa Alta, Oaxaca, during the 18th century. “Power of Attorney in Oaxaca, Mexico: Native People, Legal Culture, and Social Networks” is an ongoing digital research project that constructs a geography of indigenous legal culture through digital maps and visualizations.

The pilot for the project focuses on the district of Villa Alta, Oaxaca, during the 18th century. The multiscalar narrative of the Power of Attorney project speaks to multiple audiences, and the digital multimedia format allows visitors to further tailor their interactions with information. The site operates on many levels. It provides maps and visualizations based on original research, data culled from primary sources that can be used as a research tool, historical and geographical background information, information about how to read letters of attorney, and microhistorical narratives of power of attorney relationships. For undergraduates learning about the relationship between Spanish administration and pueblos de indios, the maps and visualizations provide an at-a-glance overview of the spatial and social connections among Indian towns, ecclesiastical and viceregal courts, and the court of the king in Madrid from the perspective of an indigenous region rather than a top-down perspective. Graduate students and scholars interested in the production of notarial records in native jurisdictions, social history and ethnohistorical methodology and the relationship between local and transatlantic processes can explore the maps, visualizations, and data in greater detail. An educated general audience interested in the history of Oaxaca’s native peoples can find a general introduction to the region, its history and geography, and the long-standing relationship between Mexico’s native people and the law.

The Relationship

The Late Antique Little Ice Age, spanning the period from 536 CE to roughly 560 CE, saw temperatures in the Northern Hemisphere drop by a degree C in less than a decade. This rapid cooling is thought to have caused widespread famine, epidemic disease, and social disruption. The relationship between cooling and social disruption is examined here using a set of high-resolution climate and historical data. A significant link between cooling and social disruption is demonstrated, but it is also demonstrated that the link is highly variable, with some societies experiencing dramatic cooling changing very little, and others experiencing only slight cooling changing dramatically. This points to variation in vulnerability, and serves to establish the Late Antique Little Ice Age as a context within which naturalistic quasi-experiments on vulnerability to climate change might be conducted.

The Marboré Cirque, which is located in the southern Central Pyrenees on the north face of the Monte Perdido Peak (42°40′0″N; 0.5°0″W; 3355 m), contains a wide variety of Holocene glacial and periglacial deposits, and those from the ‘Little Ice Age’ (‘LIA’) are particularly well developed. Based on geomorphological mapping, cosmogenic exposure dating and previous studies of lacustrine sediment cores, the different deposits were dated and a sequence of geomorphological and paleoenvironmental events was established as follows: (1) The Marboré Cirque was at least partially deglaciated before 12.7 kyr BP. (2) Some ice masses are likely to have persisted in the Early Holocene, although their moraines were destroyed by the advance of glaciers during the Mid Holocene and ‘LIA’. (3) A glacial expansion occurred during the Mid Holocene (5.1 ± 0.1 kyr), represented by a large push moraine that enclosed a unique ice mass at the foot of the Monte Perdido Massif. (4) A melting phase occurred at approximately 3.4 ± 0.2 and 2.5 ± 0.1 kyr (Bronze/Iron Ages) after one of the most important glacial advances of the Neoglacial period. (5) Another glacial expansion occurred during the Dark Age Cold Period (1.4–1.2 kyr), followed by a melting period during the Medieval Climate Anomaly. (6) The ‘LIA’ represented a clear stage of glacial expansion within the Marboré Cirque. Two different pulses of glaciation were detected, separated by a short retraction. The first pulse occurred most likely during the late 17th century or early 18th century (Maunder Minimum), whereas the second occurred between 1790 and ad 1830 (Dalton Minimum). A strong deglaciation process has affected the Marboré Cirque glaciers since the middle of the 19th century. (7) A large rock avalanche occurred during the Mid Holocene, leaving a chaotic deposit that was previously considered to be a Late Glacial moraine.

This paper aimed to study the record of the climatic variability during the last two millennia within the sebkha of Dkhila. Six climatic stages were recognized along the 104 cm core: the Warming Present (WP), the Late Little Ice Age (Late LIA), the Early Little Ice Age (ELIA), the Medieval Climatic Anomaly (MCA), the Dark Age (DA), and the Roman Warm Period (RWP). The WP stretches along the uppermost 1 cm with a high grey scale as sign of a dry climate. The Late LIA is located between 1 cm and 6 cm. The ELIA is located between 6 cm and 40 cm. The MCA spanning from 40 cm to 72 cm is marked by a sharp increase of the GS revealing a wet period. The DA appears along the part between 72 cm and 84 cm; a shift from light to dark sediments is recorded. The RWP appears between 84 cm and 104 cm. Based on the grain size distribution, two low frequency cycles were identified indicating radical global changes of climatic conditions, the differential tectonics, and the groundwater fluctuations. On the other hand, high frequency cycles indicate local modifications of the climatic conditions.

AbstractThis paper covers work intended to study the interplay of sedimentary dynamics and climatic variability over the last two millennia within Tunisia’s sebkha Souassi. Based on the Visual Core Description, and magnetic susceptibility, we date the core from sebkha Souassi to the last two millennia. Genetic grain-size distribution then provided a basis for the identification of six climatic stages, i.e. the Warming Present (WP), the Late Little Ice Age (Late LIA), the Early Little Ice Age (ELIA), the Medieval Climatic Anomaly (MCA), the Dark Ages (DA), and the Roman Warm Period (RWP). The WP stretches across the uppermost 3 cm, with a high grey scale indicating a dry climate. The Late LIA is located between 3 and 7 cm, and the ELIA between 7 and 28 cm. Intermediate values for GS indicate that this stage may be classified as moderate. The MCA spanning from 28 to 40 cm is marked by a sharp decrease in GS indicative of a wet period. The DA appear along the part between 40 and 79 cm, a shift from light to dark sediments being recorded. The RWP in turn appears between 79 and 114 cm. Based on the grain-size distribution, two low-frequency cycles were identified, indicating radical global changes in climatic conditions, differential tectonics and groundwater fluctuations. High-frequency cycles in turn attest to local modifications of climatic conditions.

And Diffusion

This essay examines the definition and early development of the term “Little Ice Age,” a source of controversy in early modern studies and historical climatology. American geologist François Matthes first used the term “little ice-age” to describe the preceding 4,000 years, during which glaciers reached their greatest extent since the final Ice Age of the Pleistocene. Matthes’s reports for the American Geophysical Union’s Committee on Glaciers, however, demonstrate the critical importance of the sixteenth through nineteenth century. This essay discusses the relationship between Matthes’s theories of glaciation and climatic periodization and those of his predecessors and contemporaries, including Charles Rabot, Gordon Manley and G.S. Callendar. This essay also examines the early adoption and diffusion of Matthes’s evocative term, which appeared in popular publications only a decade after its initial introduction.
