The Holocene temperature conundrum [PDF]

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2014
Significance Marine and terrestrial proxy records suggest global cooling during the Late Holocene, following the peak warming of the Holocene Thermal Maximum (∼10 to 6 ka) until the rapid warming induced by increasing anthropogenic greenhouses gases. However, the physical mechanism responsible for this global cooling has remained

Holocene glacier fluctuations

open access: yesQuaternary Science Reviews, 2015
A global overview of glacier advances and retreats (grouped by regions and by millennia) for the Holocene is compiled from previous studies. The reconstructions of glacier fluctuations are based on 1) mapping and dating moraines defined by ¹⁴C, TCN, OSL, lichenometry and tree rings (discontinuous records/time series), and 2) sediments from proglacial ...

Sedimentary Signatures of Persistent Subglacial Meltwater Drainage From Thwaites Glacier, Antarctica

open access: yesFrontiers in Earth Science, 2022
Subglacial meltwater drainage can enhance localized melting along grounding zones and beneath the ice shelves of marine-terminating glaciers. Efforts to constrain the evolution of subglacial hydrology and the resulting influence on ice stability in space

Palaeoecological reconstructions in the Tobol-Ishim interfluve: combination of on-site pollen data from cultural layers and off-site peatland records [PDF]

open access: yesВестник археологии, антропологии и этнографии, 2020
The study, based on uniformed criteria, summarizes a large series of palynological data and is aimed at reconstruction of the vegetation history of the second half of the Holocene based on pollen data from peatlands. The main objective of this work is to

Development history and activity characteristics of typical debris flows in the Grand Bend of the Yarlung Zangbo River since the Holocene

open access: yesDizhi lixue xuebao, 2022
Multi-period debris flows have been developed in the last glacial period of the late Pleistocene-Holocene near the Grand Bend of the Yarlung Zangbo River in southeast Tibet, which combined to form a modern large-scale fan-shaped accumulation.

Does foraminiferal test size reflect changes in palaeoenvironmental conditions?—a case study from the southern Svalbard shelf

open access: yesPolar Research, 2020
Although the environmental factors influencing the growth rate and reproduction of benthic foraminifera are known, the relationship between foraminifera test size and environmental variables remains unclear, especially on geological timescales.
