This study highlights how the erosion-resistant bryozoan limestone forms overhanging projections, leading to recurrent collapses, while the underlying chalk is eroded by storm waves and debris shedding. The research provides insights into the dynamic processes shaping this iconic coastal cliff, offering a deeper understanding of its geological evolution.

Climate and Culture Change in North America AD 900–1600

Chaco Culture — 2012 — WHEA57D0F1C64

Climate change significantly influenced the cultural trajectory of Native American societies in North America between AD 900 and 1600. This study reveals that the Medieval Warm Period (MWP) and Little Ice Age (LIA) paralleled those in Europe, with profound impacts on population dynamics, agriculture, architecture, and art. During the MWP, Native peoples experienced a cultural renaissance marked by population growth, intensified agriculture, monumental construction, and sophisticated artistry, leading to the rise of dominant centers like Chaco Canyon, Cahokia, and Casas Grandes—comparable in scale to major European cities. The onset of the LIA reversed these trends, causing sharp declines in population, agricultural production, and societal complexity, culminating in the collapse of these cultural hubs and widespread abandonment or fortification of smaller villages.

Climate change, human response and the origins of urbanism at Timbuktu: archaeological investigations into the prehistoric urbanism of the Timbuktu region on the Niger Bend, Mali, West Africa

Timbuktu — 2012 — WHEDE5A10DCFA

Archaeological research at Timbuktu, Mali, reveals that the region's prehistoric urbanism emerged as a response to significant climate shifts during the Holocene. The study suggests that human settlements in the Niger Bend expanded and developed complex social structures around 300 BCE, coinciding with periods of increased rainfall and resource abundance. These findings challenge traditional narratives about the origins of urbanization in West Africa by demonstrating its deep historical roots and adaptability to environmental changes. Researchers employed a combination of sediment analysis, radiocarbon dating, and artifact studies to reconstruct past landscapes and human activities, providing a nuanced understanding of how climate variability shaped early urban societies.

Climatic determinants of white spruce cone crops in the boreal forest of southwestern Yukon

Kluane / Wrangell-St. Elias / Glacier Bay / Tatshenshini-Alsek — 2012 — WHE7EBEC8F7D5

A groundbreaking study reveals that white spruce cone crops in the boreal forest of southwestern Yukon are primarily influenced by weather conditions two years prior, challenging conventional assumptions. Researchers analyzed 26 years of data (1986–2011) from over 700 trees across multiple sites, finding that July and August temperatures from years t-1 and t-2, along with May precipitation from year t-2, explained 54% of cone crop variation. This contradicts the traditional view linking cone crops to summer weather in the current or previous year. The study also found no periodic pattern in cone crops, indicating synchronous large crops across the Kluane region. This is the first quantitative model for predicting white spruce cone crops, offering novel insights into boreal forest ecology.

Climatic stability in the Brazilian Cerrado: implications for biogeographical connections of South American savannas, species richness and conservation in a biodiversity hotspot

Cerrado Protected Areas: Chapada dos Veadeiros and Emas National Parks — 2012 — WHE003A04B26B

Research reveals that climatic stability is a stronger predictor of squamate reptile richness in the Brazilian Cerrado than current climate variables, challenging traditional biogeographical assumptions about South American savannas. The study used machine-learning models to project the Cerrado's distribution across four time periods—current, mid-Holocene (6 ka), Last Glacial Maximum (21 ka), and Last Interglacial (120 ka)—and identified two savanna corridors: an eastern coastal corridor during the Last Interglacial and an Andean corridor during the Last Glacial Maximum. Additionally, it predicted a large refugial area in the northeastern Cerrado, suggesting that Bolivian savannas should be included within the Cerrado range, contrary to previous hypotheses linking it to the Chaco and Caatinga biomes. The findings highlight the importance of climatic stability maps for future biodiversity studies and conservation planning.

Coarsely crystalline cryogenic cave carbonate – a new archive to estimate the Last Glacial minimum permafrost depth in Central Europe

Caves of Aggtelek Karst and Slovak Karst — 2012 — WHE84A7BE6FA3

Researchers have identified coarsely crystalline cryogenic cave carbonate (CCC) as a novel paleoclimate proxy, revealing that permafrost during the Last Glacial period penetrated to depths of at least 65 meters in Central European lowlands and uplands, with an isolated finding suggesting depths of up to 285 meters in the High Tatra mountains. This discovery contrasts with typical speleothem formation, which ceased during glacial periods, while CCC precipitation was restricted to them. By analyzing stable isotope values, U-series ages, and depth data from 20 caves across Germany, the Czech Republic, Slovakia, and Poland, the study estimates permafrost depths and demonstrates that permafrost thawing phases occurred repeatedly during marine isotope stages 4, 3, and 2, with significant CCC formation between 40–21 ka BP and 17–12 ka BP. This provides critical insights into the extent and variability of permafrost in glacier-free regions.

While the Monument's visual appeal and historical importance are central to its allure, the research also explores how it interacts with other notable sites like the Baha’i temple, India Gate, Chattarpur temple, and the Red Fort itself. This work delves into the complexities of code-switching—where different cultural or symbolic codes intersect—and code-clashing, examining how these dynamics shape visitor experiences and the site's identity.

Coffee Palaces in Australia: A Pub with No Beer

Royal Exhibition Building and Carlton Gardens — 2012 — WHE8728A48EF5

Coffee palaces, unique temperance hotels built in late 19th-century Australia, emerged as grand architectural marvels designed to promote sobriety and family values. These structures, adorned with High Victorian ornamentation, were a response to the temperance movement's peak during the 1880s, reflecting the economic boom fueled by the gold rush and the demand for ostentatious display. While their lifespan was short-lived, coffee palaces significantly influenced Australia's cultural landscape, drawing parallels to Enlightenment-era European coffee houses that fostered intellectual discourse and progress. This study examines the rise and decline of coffee palaces, arguing that they were modeled on historical coffee houses, which symbolized modernity and reason. The research approach involves historical analysis, architectural context, and social implications, providing insights into the temperance movement's legacy and its impact on Australian society.

Comercio protohistórico: el registro del Nordeste peninsular y circulación de mineral de plomo en Ibiza y el Bajo Priorato (Tarragona)

Ibiza, Biodiversity and Culture — 2012 — WHE3ACE22BB85

A new analysis of mineral and metal samples from Ibiza reveals that the island's silver-bearing galena was exploited alongside lead ore from Cartagena during the Phoenician-Tartessian period, challenging previous assumptions about trade networks in the region. While prior research suggested lead from the Baix Priorat (Tarragona) was circulating in these networks, this study found no evidence of it on Ibiza, indicating a more complex and localized trade system. The findings suggest that Ibiza served as a key hub for metal exchange between the Iberian Peninsula and Carthage, with possible bidirectional flows of materials. The research combines archaeological and analytical techniques to trace the origins and circulation of lead ore, offering insights into ancient economic and cultural connections in the western Mediterranean.

Commemoration and Pilgrimage in the Ancient World: Troy and the Stratigraphy of Cultural Memory

Archaeological Site of Troy — 2012 — WHED9E90DD5D0

Troy, a Bronze Age site on the Hellespont, emerged as a focal point for ancient commemoration and pilgrimage, driven by enduring cultural memory of the Trojan War. Over centuries, its landscape became a destination for 'pilgrims' seeking to engage with the mythic narratives of heroes like Helen and Achilles. The study reveals how shared memories, though likely distorted, shaped Troy's significance as both an archaeological site and a symbolic landmark in ancient Greek culture. By analyzing stratigraphic layers of cultural memory—linking Homer's Iliad to physical and emotional experiences of the Trojan landscape—the research demonstrates the interplay between legend, geography, and collective identity.

Commensuration and styles of reasoning: Venice, cost–benefit, and the defence of place

Venice and its Lagoon — 2012 — WHE2B5422870F

Quantitative economic calculations in environmental assessments can both stabilize and disrupt the objectivity of numbers, depending on how the subject and object of calculation are represented. This study analyzes a controversial cost–benefit analysis for Venice’s flood protection scheme, revealing that the 'commensuration' and standardization facilitated by numerical data depend heavily on the conceptual framing of urban and natural environments. The research traces differing 'styles of calculation,' demonstrating how economic representations intersect with political symbolism and intervention aims, ultimately influencing debates over realism and accuracy in such assessments.

Communicating Environment in the Okavango Delta, Botswana

Okavango Delta — 2012 — WHE184186BF3F

A study on environmental communication in the Okavango Delta, Botswana, reveals that diverse media channels significantly influence pro-environmental behaviors and attitudes.
