Neoglacial climate anomalies and the Harappan metamorphosis [PDF]

Climate of the Past, 2018
Climate exerted constraints on the growth and decline of past human societies but our knowledge of temporal and spatial climatic patterns is often too restricted to address causal connections.

Holocene neoglacial events in the Bransfield Strait (Antarctica). Palaeocenographic and paleoclimatic significance

Scientia Marina, 2006
Geochemical analysis, micropalaeontological analysis and radiometric dating techniques were performed on four gravity cores, G-1, G-2, A-3 and A-6, recovered during the BIO Hesperides expeditions GEBRA-93 and FRUELA-96 from the Bransfield Strait

Pan-Arctic Peatlands Have Expanded During Recent Warming. [PDF]

Glob Chang Biol
Arctic peatland carbon is important because it represents a large carbon stock that may be vulnerable to climate change. This work explores the expansion and/or shrinkage of Arctic peatlands using observations in two north–south transects in Canada and in Europe.

Hydrology and Ecological Evolution in a Permafrost Region in Northeast China Since the Late Pleistocene. [PDF]

Ecol Evol
Continuous hydrology and ecological evolution records of permafrost regions in Northeast China since the late Pleistocene (30 cal. ka BP) are obtained. Responses of hydrology and ecosystem dynamics to the climate cycle on the millennial scale and regional environmental effects related to permafrost.

Mid-Holocene Antarctic sea-ice increase driven by marine ice sheet retreat [PDF]

Climate of the Past, 2021
Over recent decades Antarctic sea-ice extent has increased, alongside widespread ice shelf thinning and freshening of waters along the Antarctic margin. In contrast, Earth system models generally simulate a decrease in sea ice.

¹⁰Be age control of glaciation in the Beartooth Mountains, USA, from the latest Pleistocene through the Holocene [PDF]

Geochronology, 2022
Alpine glaciers in the western United States are often associated with late Holocene Little Ice Age (LIA) advances. Yet, recent studies have shown many of these glacial landforms are remnants of latest Pleistocene retreat with only the most cirque ...

Episodic Neoglacial expansion and rapid 20th century retreat of a small ice cap on Baffin Island, Arctic Canada, and modeled temperature change [PDF]

Climate of the Past, 2017
Records of Neoglacial glacier activity in the Arctic constructed from moraines are often incomplete due to a preservation bias toward the most extensive advance, often the Little Ice Age.

Neoglaciation in the Southern Kenai Mountains, Alaska [PDF]

Annals of Glaciology, 1990
A preliminary late-Holocene glacial chronology from the west flank of the southern Kenai Mountains, Alaska, is characterized by two major episodes of advance. Outlet glaciers of both the Harding Icefield and the Grewingk-Yalik ice complex were expanding across their present positions at 545 A.D. and again during the Little Ice Age, about 1500 A.D.

Cirque Glacier on South Georgia Shows Centennial Variability over the Last 7000 Years

Frontiers in Earth Science, 2018
A 7000 year-long cirque glacier reconstruction from South Georgia, based on detailed analysis of fine-grained sediments deposited downstream in a bog and a lake, suggests continued presence during most of the Holocene.

Precipitation as the main driver of Neoglacial fluctuations of Gualas glacier, Northern Patagonian Icefield [PDF]

Climate of the Past, 2012
Glaciers are frequently used as indicators of climate change. However, the link between past glacier fluctuations and climate variability is still highly debated.
