Last Glacial Maximum and deglacial branched GDGT‐based palaeotemperature reconstruction from a subtropical Australian wetland

Journal of Quaternary Science, EarlyView.
ABSTRACT Future projections of climate change in the subtropics suggest warming and drying, while evidence from warm periods in the past shows increases in subtropical temperatures and precipitation. Eastern Australia is subject to interannual hydroclimate drivers and has experienced extreme flooding and droughts in recent years.

Climate and catchment influence the postglacial succession of three lakes in south‐central Baffin Island (Nunavut), Canada

Journal of Quaternary Science, EarlyView.
ABSTRACT Understanding postglacial ontogeny in Arctic lakes helps contextualize modern‐day climatic change. We used sediment cores to characterize ecological succession in three south‐central Baffin Island lakes from deglaciation (c. 7–8k cal a BP) to present.

Stad Slide: Preconditioning and failure of one of the world's largest megaslides

Journal of Quaternary Science, EarlyView.
ABSTRACT Submarine landslides can generate tsunamis and pose risks to underwater infrastructure, but a lack of direct observations of such slides hinders our understanding of their development and hazard potential. Studying the morphology of past slides can offer insights into their preconditioning and failure.

The mineral and isotopic signatures of glacially eroded sediments exported from Hudson Strait to the Labrador Sea during Hudson Strait Heinrich events H0 to H4

Journal of Quaternary Science, EarlyView.
ABSTRACT The sediment signature of glacial erosion products exported from Hudson Strait to the Labrador Sea during Hudson Strait Heinrich (HS‐H) events is evaluated using four distinct proxies: paired δ18Ο and δ13C data on the carbonate fraction, εNd and U–Pb isotopes in the silicate fraction, the mineral composition of the <2 mm bulk sediment fraction,

Intensification of the Southern Hemisphere westerly winds during the last deglaciation (18.5–14.0 cal ka BP): Evidence from Pearly Beach wetland on the southern Cape coast of South Africa

Journal of Quaternary Science, EarlyView.
ABSTRACT The southwestern Cape of South Africa experiences a complex and dynamic climate, shaped by the interplay between the temperate Southern Hemisphere westerly winds and the subtropical easterlies. Despite the climatic sensitivity of the region, relatively few studies have examined how conditions have varied since the last deglaciation in response

Charcoal evidence traces diverse fungal metabolic strategies to the Late Paleozoic

iScience
Summary: Wood decomposition through fungal activity is essential to the natural carbon cycle. There are three primary patterns of wood decay: white rot, brown rot, and soft rot. However, geological records of wood decay mainly originate from fossil woods,

High‐resolution coral oxygen and carbon isotope records reveal temperature and autotrophy dynamics in a Mediterranean climate change hotspot

Limnology and Oceanography, EarlyView.
Abstract The Mediterranean Sea is warming at a rate exceeding the global average. Long‐term, high‐resolution data are essential for contextualizing changes within broader temporal scales, and coral skeletons provide valuable environmental archives, especially in data‐sparse regions or as supplements to existing records.
