Charles Travis, Francis Ludlow, Ferenc Gyuris, Historical Geography, GIScience and Textual Analysis: Landscapes of Time and Place, New York, Springer International Publising, 2020, 1 - 272pp, Notes: [This book illustrates how literature, history and geographical analysis complement and enrich each other's disciplinary endeavors. The Hun-Lenox Globe, constructed in 1510, contains the Latin phrase 'Hic sunt dracones' ('Here be dragons'), warning sailors of the dangers of drifting into uncharted waters. Nearly half a millennium earlier, the practice of 'earth-writing' (geographia) emerged from the cloisters of the great library of Alexandria, as a discipline blending the twin pursuits of Strabo's poetic impression of places, and Herodotus' chronicles of events and cultures. Eratosthenes, a librarian at Alexandria, and the mathematician Ptolemy employed geometry as another language with which to pursue 'earth-writing'. From this ancient, East Mediterranean fount, the streams of literary perception, historical record and geographical analysis (phenomenological and Euclidean) found confluence. The aim of this collection is to recover such means and seek the fount of such rich waters, by exploring relations between historical geography, geographic information science (GIS) / geoscience, and textual analysis. The book discusses and illustrates current case studies, trends and discourses in European, American and Asian spheres, where historical geography is practiced in concert with human and physical applications of GIS (and the broader geosciences) and the analysis of text - broadly conceived as archival, literary, historical, cultural, climatic, scientific, digital, cinematic and media. ], Book, PUBLISHED  DOI  URL
Mapping the Irish Rath (Ringfort): Landscape Settlement Patterns in the Early Medieval Period in, editor(s)Charles Travis, Francis Ludlow, Ferenc Gyuris , Historical Geography, GIScience and Textual Analysis: Landscapes of Time and Place, New York, Springer International Publising, 2020, [Robert Legg, Francis Ludlow, Charles Travis], Notes: [The landscape motif of the Irish rath, or ringfort, is closely associated with early medieval settlement in Ireland (400-1100 AD). Ringforts were circular or near-circular enclosures, typically constructed by digging a surrounding ditch, the material from which would be used to construct an adjacent earthen bank. The majority of ringfort sites feature a single ditch and bank (known as a univallate site), but double or triple banked sites are also known, and are described as bivallate and trivallate, respectively. Variations in ringfort morphology and in the physical geographical characteristics of their site location provides a valuable field record that is indicative of the diversity of socioeconomic roles played by these sites and of the status of individuals and clans responsible for their construction and occupation. Ringfort locations generally represented the habitation centre of the farmstead, comprising one or more dwellings. Petal-shaped fields would surround the site. This chapter discusses a geographical information science (GIScience) and geostatistical study of ringfort locations in the Irish Midlands, utilizing data sourced from the Irish Government's Department of the Environment, Heritage and Local Government archaeological site spatial database. This study also draws on archaeological and historical database records and fieldwork analysis in order to consider the relations between physical environmental context and ringfort settlement patterns.], Book Chapter, PUBLISHED  DOI
Guillet, S., Corona, C., Ludlow, F., Oppenheimer, C., Stoffel, M., Climatic and Societal Impacts of a "Forgotten" Cluster of Volcanic Eruptions in 1108-1110 CE, Scientific Reports, 10, 2020, p1-10 , Notes: [Recently revised ice core chronologies for Greenland have newly identified one of the largest sulfate deposition signals of the last millennium as occurring between 1108 and 1113 CE. Long considered the product of the 1104 CE Hekla (Iceland) eruption, this event can now be associated with substantial deposition seen in Antarctica under a similarly revised chronology. This newly recognized bipolar deposition episode has consequently been deemed to reveal a previously unknown major tropical eruption in 1108 CE. Here we show that a unique medieval observation of a "dark" total lunar eclipse attests to a dust veil over Europe in May 1110 CE, corroborating the revised ice-core chronologies. Furthermore, careful evaluation of ice core records points to the occurrence of several closely spaced volcanic eruptions between 1108 and 1110 CE. The sources of these eruptions remain unknown, but we propose that Mt. Asama, whose largest Holocene eruption occurred in August 1108 CE and is credibly documented by a contemporary Japanese observer, is a plausible contributor to the elevated sulfate in Greenland. Dendroclimatology and historical documentation both attest, moreover, to severe climatic anomalies following the proposed eruptions, likely providing the environmental preconditions for subsistence crises experienced in Western Europe between 1109 and 1111 CE.], Journal Article, PUBLISHED  TARA - Full Text  DOI  URL

B.M.S. Campbell, F. Ludlow, Climate, disease and society in late-medieval Ireland, Proceedings of the Royal Irish Academy, 120C, 2020, Notes: [Palaeoclimatic data are used to track the significant changes in atmospheric circulation patterns and weather conditions that affected Ireland between 1000 and 1500CE. How these climatic developments and associated shifts in the epidemiological environment were mapped onto Irish society is explored using a tree-ring chronology reflecting the retreat and advance of oak woodland. Years characterised by significant weather-related food scarcities are identified from the Irish Annals in combination with the independent record of English chronicles, grain yields and prices. Between the thirteenth and the fifteenth centuries the experience of the two countries is shown to have diverged. It is suggested that in late-medieval Ireland scarcity heightened the resort to violence and was from 1348 often a proximate cause of plague outbreaks. In combination, scarcity, violence and plague helped entrap fifteenth-century society in a low-level equilibrium of sparse population, economic under-development, scarcely disguised poverty and low resilience to natural hazards.], Journal Article, IN_PRESS

Volcanic fallout in well-dated Arctic ice core records, climate proxies, and Earth system modeling show that this transition occurred during an extreme cold period resulting from a massive eruption of Alaska's Okmok volcano early in 43 BCE. Written sources describe unusual climate, crop failures, famine, disease, and unrest in the Mediterranean immediately following the eruption-suggesting significant vulnerability to hydroclimatic shocks in otherwise sophisticated and powerful ancient states. Such shocks must be seen as having played a role in the historical developments for which the period is famed.], Journal Article, PUBLISHED  DOI  URL

L., Demystifying Collapse: Climate, Environment, and Social Agency in Pre-Modern Societies, Millennium, 17, 2020, Notes: [Collapse is a term that has attracted much attention in social science literature in recent years, but there remain substantial areas of disagreement about how it should be understood in historical contexts. More specifically, the use of the term collapse often merely serves to dramatise long-past events, to push human actors into the background, and to mystify the past intellectually. At the same time, since human societies are complex systems, the alternative involves grasping the challenges that a holistic analysis presents, taking account of the many different levels and paces at which societies function, and developing appropriate methods that help to integrate science and history. Often neglected elements in considerations of collapse are the perceptions and beliefs of a historical society and how a given society deals with change; an important facet of this, almost entirely ignored in the discussion, is the understanding of time held by the individuals and social groups affected by change; and from this perspective 'collapse' depends very much on perception, including the perceptions of the modern commentator. With this in mind, this article challenges simplistic notions of 'collapse' in an effort to encourage a more nuanced understanding of the impact and process of both social and environmental change on past human societies.], Journal Article, IN_PRESS  DOI

Here, we analyse some of the longest available precipitation records globally, for England and Wales, Scotland and Ireland. To assess the credibility of these records and extend them further back in time, we statistically reconstruct (using independent predictors) monthly precipitation series representing these regions for the period 1748-2000. By applying the Standardised Precipitation Index at 12-month accumulations (SPI-12) to the observed and our reconstructed series we re-evaluate historical meteorological droughts. We find strong agreement between observed and reconstructed drought chronologies in post-1870 records, but divergence in earlier series due to biases in early precipitation observations. Hence, the 1800s decade was less drought prone in our reconstructions relative to observations. Overall, the drought of 1834- 1836 was the most intense SPI-12 event in our reconstruction for England and Wales. Newspaper accounts and documentary sources confirm the extent of impacts across England in particular. We also identify a major, 'forgotten' drought in 1765-1768 that affected the British-Irish Isles. This was the most intense event in our reconstructions for Ireland and Scotland, and ranks first for accumulated deficits across all three regional series. Moreover, the 1765-1768 event was also the most extreme multi-year drought across all regional series when considering 36-month accumulations (SPI-36). Newspaper and other sources confirm the occurrence and major socio-economic impact of this drought, such as major rivers like the Shannon being fordable by foot. Our results provide new insights into historical droughts across the British Irish Isles. Given the importance of historical droughts for stress-testing the resilience of water resources, drought plans and supply systems, the forgotten drought of 1765-1768 offers perhaps the most extreme benchmark scenario in more than 250-years.], Journal Article, ACCEPTED  TARA - Full Text  DOI  URL

At the local scale, erupted lava, ash and gases can have a drastic impact on the environment, with sometimes severe impacts on ecosystems, human health and economies. Global scale impacts can be produced by major volcanic eruptions, like those of Mt. Pinatubo (1991), or Tambora (1815). Such large-scale effects are due primarily to the injection of sulfur into the stratosphere, resulting in the formation of sulfate aerosols. The primary impact of these aerosols is a decrease in global temperature; however, the aerosols can also affect atmospheric circulation and precipitation patterns, leading to complex regional-scale climate impacts. Information on the climate anomalies resulting from volcanic eruptions in the Earth's past therefore provides important insights for understanding the global and regional climate responses to external forcing agents. This in turn informs predictions of future climate change, such as that due to projected increases in anthropogenic greenhouse gases. Volcanically induced climate changes also provide valuable test cases for understanding the impact of climate variability on society.], Journal Article, PUBLISHED

My main research interests lie in climate history, a discipline at the intersection of environmental history and climatology. It is a young field but has grown in prominence with concerns over the pace of current and projected climate change, as well as the extent to which societies might adapt (or fail to adapt) to these changes. Climate history offers important insights here, with its major foci being (1) the reconstruction of past climatic conditions using the evidence of historical archives (an approach also often defined as historical climatology), and (2) the impacts of past climatic changes on societies. In my experience, most climate historians focus on one strand, but my broad background in geography, economics and statistics (TCD) and history (Harvard, Yale, Munich) has positioned me well to contribute to both. My interest is frequently to act as a bridge between scholars in the natural and human sciences, communicating (and "translating") findings, methods and sources of relevance. I also aim to promote best practice in climate history, taking a leadership role through, for example, involvement in the PAGES Working Groups ("Volcanic Impacts on Climate and Society", "Climate Reconstruction and Impacts from the Archives of Societies"). This frequently involves emphasizing the need to critically examine all written sources (e.g., bringing to bear knowledge of authorial intent and historical context) and the avoidance of environmentally deterministic interpretations of correspondences between historical events and climatic trends extracted from natural archives such as tree-rings and ice-cores. My approach is best illustrated by reference to two studies. In 2015 I was lead historian in major corrections to Greenland and Antarctic ice-core chronologies that detail the history of past explosive volcanism, assessing the accuracy of corrections by reference to historically observed volcanic "dust-veils" (associated with discoloured or diminished sunlight, often reported by past observers). This study was published in Nature in 2015 (Sigl et al., 2015) and has over 480 citations (Google Scholar, as of January 2020). I next built upon this new volcanic history with a study in Nature Communications (Manning et al., 2017), in which I acted as corresponding author. This employed written observations of Nile flooding (622-1902 CE) to establish the impact of explosive volcanism on the Nile, confirming climate models that predicted post-eruption reductions of the agriculturally critical summer flooding. The study then applied this understanding to questions concerning the causes of violent revolts in Ancient Egypt's Ptolemaic era (305-30 BCE), showing that these aligned with explosive eruptions (and hence poor summer flooding and related socioeconomic problems). This study received widespread attention, having an Attention score falling in the top 5% of all tracked research (Altmetric). It is also the subject of a documentary that first aired on the Smithsonian Channel in January 2020, scheduled for world release in later 2020. Citations: Manning, J.
