Abstract Temperature and precipitation variability in monsoonal Asia is central to understanding regional climate dynamics and global teleconnections. How post‐LGM warming and hydroclimate change unfolded in Northeast Asia, and how they were linked to external forcing, remain poorly constrained. Here we present high‐resolution pollen‐derived reconstructions of mean annual temperature (MAT) and precipitation (MAP) from Xiaolongwan Maar Lake, spanning the Last Glacial Maximum (LGM) to the present. From the LGM to the mid‐Holocene, MAT increased by ∼9.0 ± 2.2°C and MAP by ∼470 ± 121 mm. During ∼1

    There is no contradiction . The traditional textual interpretations of Noah's Ark as a global, conventional wooden ship inherently conflict with the laws of material physics (structural elasticity versus mass load), biogeographical distribution of endemic fauna, and global hydrological constraints. This working paper proposes a novel alternative hypothesis by shifting the paradigm from a maritime vessel to a highly secure, terrestrial, semi-subterranean bunker complex equipped with ancient disaster-mitigation technologies.

    Abstract A lack of well-dated archaeological and palaeontological sequences containing proxy-based palaeoenvironmental information has hindered the reconstruction of long-term human-biodiversity interactions in Mexico. Here, we re-evaluate the stratigraphy of the Huechil Chamber in Loltún Cave, a key Yucatán site whose archaeo-palaeontological sequence, dating from the Pleistocene to the Late Holocene, provides critical insights into the environmental conditions that shaped human settlement from near the onset of our species’ presence in this part of the world. Despite localised disturbances,

    This dataset contains multiproxy palaeoecological and geochemical data used to reconstruct Late Glacial and Early Holocene environmental and climatic changes at Lake Prokoško (1670 m a.s.l.), located in the Vranica Mountains, Bosnia and Herzegovina. The primary research objective was to provide a high-resolution, quantitative mean July air temperature (TJuly) reconstruction for the climatically transitional Western Balkan region, and to evaluate the spatial expression of the Younger Dryas (YD) cooling along the European West-East summer climatic gradient. Data were collected from an 11.4 m con

    Introduction to Archaeological Science offers a clear, comprehensive introduction to archaeological science for students encountering the field for the first time. This book presents the principal areas that shape contemporary archaeological science, combining accessible explanations with strong conceptual foundations. It introduces the development of the discipline from the 19th century to the present, before exploring relative and absolute dating methods; past environments and climate; geoarchaeology; archaeobotany; zooarchaeology; human osteology; biomolecular archaeology, including ancient

    Ballantyne [2026. Did the Cairngorm Mountains support glaciers during the Little Ice Age? Scottish Geographical Journal (this issue)] expresses scepticism of the evidence for glacier ice during the Little Ice Age (LIA) in Coire an Lochain (Cairngorm Mountains), arguing that the Holocene exposure ages of moraine boulders [Kirkbride, M.P., Everest, J.D., Benn, D.I., Gheorghiu, D.

    This paper began as an attempt to understand the geology of the Boston Basin for purposes determining a risk profile and remediation plan as part of a Clean Water Act legal notice. That research resulted in an assessment that no coherent, evidence-based explanation for the geology of the Boston Basin exists in the published literature. However, the literature captured extensive evidence that could be analyzed under new theories and methodologies. Over a century of geological surveys, engineering boring logs, and geotechnical investigations have documented a suite of anomalies that the prevaili

    The Younger Dryas Period, dating approximately 12,800 years ago, is characterized by an abrupt cooling event associated with widespread ecological disruption and mass extinction. Evidence suggests that this rapid climate shift may have been triggered by a cosmic event, forming the basis of the Younger Dryas impact hypothesis. This study compares sedimentary markers associated with the Younger Dryas with those found at known high-energy impact sites, including comets, airbursts, and lightning-related events. To establish a baseline for cosmic impact features, we analyzed soil and mineral sample

    This study investigates the hypothesis that Earth collided with fragments of a disintegrating comet, triggering Younger Dryas climate change 12,800 years ago. This collision created environmental conditions at Abu Hureyra, Syria, that favored the earliest known continuous cultivation of domestic-type grains and legumes, along with animal management, adding to the pre-existing practice of hunting-and-gathering. The proposed airburst coincided with a significant decline in local populations and led to architectural reorganizations of the village. These events immediately followed the deposition

    One explanation of the abrupt cooling episode known as the Younger Dryas (YD) is a cosmic impact or airburst at the YD boundary (YDB) that triggered cooling and resulted in other calamities, including the disappearance of the Clovis culture and the extinction of many large mammal species. We tested the YDB impact hypothesis by analyzing ice samples from the Greenland Ice Sheet Project 2 (GISP2) ice core across the Bølling-Allerød/YD boundary for major and trace elements. We found a large Pt anomaly at the YDB, not accompanied by a prominent Ir anomaly, with the Pt/Ir ratios at the Pt peak exce
