Abstract. Sedimentary charcoal records are widely used to reconstruct regional changes in fire regimes through time the geological past. Existing global compilations not geographically comprehensive and do provide consistent metadata for all sites. Furthermore, age models provided these harmonised many based on older calibrations of radiocarbon ages. These issues limit use existing research into past regimes. Here, we present an expanded database records, accompanied by new recalibration...
Understanding the evolution of Holocene climate is key for predicting what different futures may look like. However, global proxy and model-based reconstructions disagree on general over past 11.7 thousand years. Proxy-based demonstrate a Climatic Optimum in mid-Holocene, whilst approaches show trend increasing temperatures throughout. This disagreement largely believed to relate seasonal biases within proxy-based reconstructions, although model based-reconstructions are not without their...
Future climate projections are expected to have a substantial impact on boreal lake circulation regimes, with warmer climates and higher organic loads leading intensified thermo-stratification brownification. Understanding sensitivity is therefore critical for mitigating potential ecological societal impacts. The Holocene Thermal Maximum (HTM; ca 7-5 ka BP) provides valuable analogue investigate responses devoid of major anthropogenic influences.In this presentation we present...
Internal variations of climate can significantly influence global warming trends, especially at the continental scale, and could contribute to recent abnormal observed over Europe. Model-based studies highlight that centennial variability North Atlantic strongly affect this sector. However, a lack high-resolution paleoclimate data does not allow proper evaluation real existence such mode nor its amplitude. Here, we compile series annual proxy-based reconstructions Europe from diverse sources...
Palaeoclimate archives record climate variability on a range of timescales from seasonal changes in the system to multi millennial variability. Decision makers working mitigation and adaptation typically work one year few decades ahead only. This means that order for palaeoclimate reconstructions be most relevant policy decisions, temporal resolution also need at an annual decadal scale. However, traditional approaches quantitatively reconstruct are often expensive require lot archive...
ABSTRACT The Last Glacial to Interglacial Transition (LGIT) is a period of climatic instability. δ 18 O records are ideal for investigating the LGIT as this proxy responds rapidly even minor oscillations. Lacustrine carbonates offer opportunity investigate spatial diversity in patterns change during but requires generation from range latitudinal and longitudinal settings. This study presents coupled pollen stable isotopic lacustrine spanning Windermere Interstadial (the British equivalent...
ABSTRACT Wood macrofossil remains of alder and willow/poplar have been recovered from a sediment sequence in the valley Turker Beck Vale Mowbray, North Yorkshire. These yielded radiocarbon dates early Devensian Late Glacial (14.7–14k cal bp ), equivalent to part Greenland Interstadial (GI‐1e) GRIP ice‐core record. are earliest recorded for presence British Isles. Associated biological provided palaeoenvironmental record this Interstadial, generally indicative open environments dominated by...
During the Holocene, European high latitudes experienced substantial alterations in temperature and precipitation patterns. These changes were driven by a complex combination of factors, including impacts orbital solar forcing on insolation, dynamics ocean-atmospheric circulation regimes, various related feedback mechanisms. Sedimentation regimes Boreal lakes can be sensitive to these climate thus provide valuable archive better understand climatic processes. Limitations sampling resolution,...
Palaeoclimate reconstructions from proxy data provides the opportunity to extend instrumental climate record over last few millennia. This extension allows identification of trends which are not observed in short observational period, contextualise current changes system, and be used model sensitivity tests strengthen future projections. The skill reconstructing accurate palaeoclimate on centennial millennial timescales using has increased past decades, however at high temporal resolutions...
Global warming is leading to more persistent boreal summers in the Northern Hemisphere, characterised by a longer season with extreme heat waves. These seasonal changes have already led many ecological and socio-economic implications. Statistical significance between summer weather persistence its potential drivers weak due short instrumental period, turn preventing skilful predictions. In this study, we develop new proxy for based on varve thickness measurements extend observations further...
Abstract. Quantification of proxy records obtained from geological archives is key for extending the observational record to estimate rate, strength, and impact past climate changes, but also validate model simulations, improving future predictions.

We have developed annually laminated...
The last British-Irish Ice Sheet (BIIS) created a landscape with many sedimentary basins that preserve archives of paleoenvironmental and paleoclimatic change during the Last Glacial-Interglacial Transition (LGIT; ~ 18-8 ka BP). typical lithostratigraphic succession these is composed minerogenic/allogenic sediments formed cold climatic conditions organic-rich/authigenic warmer climates. This paper presents multi-core lithostratigraphy compiled from extant lake surrounding basin at Llangorse...
