“…It also suggests that the study area was still largely sea ice-covered and that AW entering the Nordic Seas was subducted and below the usual habitat depth range of planktic foraminifers (Rasmussen et al, 2014a), implying a relatively deep position of the halocline. At our locations, no indications of enhanced surface warming during BøllingeAllerød (BeA) is found, in spite of relatively high air temperatures recorded over Greenland Rasmussen et al, 2006) and Europe (e.g., Friedrich et al, 2001;Ammann et al, 2013). The lack of a distinct BeA warming in paleoceanographic records from the Nordic Seas is a common feature (e.g., Rasmussen et al, 2007), although the warming is found in North Atlantic records (Waelbroeck et al, 2001).…”

“…In the late Pleistocene and early Holocene, rising atmospheric CO 2 concentrations, followed by intense warming and increases in humidity led to the rapid development of closed forests in most of northern and western Europe (e.g., [54, 55]). These forests would have been much more difficult for humans to burn, and indeed there is little evidence for anthropogenic burning in Europe in the early Holocene [56], while at the same time a large part of the Pleistocene megafauna went extinct [57].…”

Large Scale Anthropogenic Reduction of Forest Cover in Last Glacial Maximum Europe

et al. 2016

Reconstructions of the vegetation of Europe during the Last Glacial Maximum (LGM) are an enigma. Pollen-based analyses have suggested that Europe was largely covered by steppe and tundra, and forests persisted only in small refugia. Climate-vegetation model simulations on the other hand have consistently suggested that broad areas of Europe would have been suitable for forest, even in the depths of the last glaciation. Here we reconcile models with data by demonstrating that the highly mobile groups of hunter-gatherers that inhabited Europe at the LGM could have substantially reduced forest cover through the ignition of wildfires. Similar to hunter-gatherers of the more recent past, Upper Paleolithic humans were masters of the use of fire, and preferred inhabiting semi-open landscapes to facilitate foraging, hunting and travel. Incorporating human agency into a dynamic vegetation-fire model and simulating forest cover shows that even small increases in wildfire frequency over natural background levels resulted in large changes in the forested area of Europe, in part because trees were already stressed by low atmospheric CO2 concentrations and the cold, dry, and highly variable climate. Our results suggest that the impact of humans on the glacial landscape of Europe may be one of the earliest large-scale anthropogenic modifications of the earth system.

“…Van Husen (2000) correlates Daun advances to the Older Dryas, that lies between the Bølling and Allerød warm periods. In that case, the Daun stadial may correlate to either the Aegelsee (Older Dryas) or the Gerzensee (Intra-Allerød) cold pulse, which were recognized by del 18 O and paleobotanical evidence from lakes in northwest Swiss forelands (Lotter et al, 1992(Lotter et al, , 2012Ammann et al, 2013).…”
