The Ice Core Gas Age‐Ice Age Difference as a Proxy for Surface Temperature
Geophysical Research Letters, 2021 Ice cores provide detailed records of past climate change. Water stable isotopes are the most commonly used ice core climate proxy, but their quantitative interpretation remains challenging.

How cold was the Last Glacial Maximum? [PDF]
Geophysical Research Letters, 2006 We present a new approach to estimate the magnitude of global‐mean cooling (dTLGM) at the Last Glacial Maximum (LGM) relative to the pre‐industrial climate, by combining an ensemble of coupled climate model simulations with empirical constraints on regional cooling inferred from proxy data.

Geophysical Research Letters, 2016 Substantial quantities of organic carbon (OC) are stored in the thick, ice‐rich, and organic‐rich sediments called yedoma deposits, distributed in eastern Siberia and Alaska today.

Clumped‐Isotope Constraint on Upper‐Tropospheric Cooling During the Last Glacial Maximum
AGU Advances, 2022 Ice cores and other paleotemperature proxies, together with general circulation models, have provided information on past surface temperatures and the atmosphere's composition in different climates.

Glacial geomorphology of Newfoundland, Canada
Journal of MapsWe present a synthesis of glacial geomorphology comprising Newfoundland and the surrounding continental shelf. During the last glaciation, this region was encompassed by the Newfoundland Ice Cap that coalesced with the Laurentide Ice Sheet and extended ...

A flint artefact (Accession No. DONMG 2016.7.1) from Lindholme, South Yorkshire
Journal of Lithic Studies, 2016 One of the last papers which Alan was working on when he died was a short note on a flint artefact from the surface of a gravel scrape at Lindholme in South Yorkshire.

Tropical glacier reconstructions during the Last Glacial Maximum in Costa Rica
Revista Mexicana de Ciencias Geológicas, 2021 Numerous high elevation tropical mountains around the world show evidence of past glacial activity during the Last Glacial Maximum (LGM). Cerro Chirripó in Costa Rica exhibits paleoglacial landforms such as glacial cirques, moraine deposits and polished

Glacial history of the Antarctic Peninsula since the Last Glacial Maximum?a synthesis [PDF]
Polar Research, 2002 The extent of ice, thickness and dynamics of the Last Glacial Maximum (LGM) ice sheets in the Antarctic Peninsula region, as well as the pattern of subsequent deglaciation and climate development, are not well constrained in time and space. During the LGM, ice thickened considerably and expanded towards the middle–outer submarine shelves around the ...

How dusty was the last glacial maximum over Europe?
Quaternary Science Reviews, 2021 Our study focuses on European loess sequences, particularly the eolian intervals in between the observed pedogenic units. The classical concept of soil formation from parent material is reformulated to estimate of the duration and the associated sedimentation rate (SR) and mass accumulation rate (MAR) of these paleodust intervals.

FEBS Letters, EarlyView.We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.
