“…These marine sequences reveal rapid shifts between weak and strong modes of deep convection during the last deglaciation with potential consequences for European environments that need to be further assessed. The Northern Iberian Peninsula (IP), located within the polar front during the time of the coldest temperatures in GS-1 (10), is a very sensitive location to determine the exact sequence of temperature and hydrological changes in Southern Europe during this stadial, not yet well resolved due to the lack of high-resolution records (11)(12)(13). Here, we present the first stalagmite record, to our knowledge, that covers the entire GS-1 period in Southern Europe, providing an excellent and independent chronological framework and a high-resolution climate reconstruction of this event, allowing understanding of the climate mechanisms that caused the mid-GS-1 transition.…”

Greenland Stadial 1 (GS-1) was the last of a long series of severe cooling episodes in the Northern Hemisphere during the last glacial period. Numerous North Atlantic and European records reveal the intense environmental impact of that stadial, whose origin is attributed to an intense weakening of the Atlantic Meridional Overturning Circulation in response to freshening of the North Atlantic. Recent high-resolution studies of European lakes revealed a mid–GS-1 transition in the climatic regimes. The geographical extension of such atmospheric changes and their potential coupling with ocean dynamics still remains unclear. Here we use a subdecadally resolved stalagmite record from the Northern Iberian Peninsula to further investigate the timing and forcing of this transition. A solid interpretation of the environmental changes detected in this new, accurately dated, stalagmite record is based on a parallel cave monitoring exercise. This record reveals a gradual transition from dry to wet conditions starting at 12,500 y before 2000 A.D. in parallel to a progressive warming of the subtropical Atlantic Ocean. The observed atmospheric changes are proposed to be led by a progressive resumption of the North Atlantic convection and highlight the complex regional signature of GS-1, very distinctive from previous stadial events.

“…12,500 cal yr BP according to our chronology. It could be linked to warmer and wetter conditions towards the end of the Younger Dryas, and summer temperatures actually followed a steep increasing trend from approximately this date onwards in the nearby site of La Roya (Munoz Sobrino et al, 2013). Moreover, pine forests were important in other areas of northwestern Iberia during this stadial (Munoz Sobrino et al, 2007).…”

We reconstructed vegetation responses to climate oscillations, fire and human activities since the last glacial maximum in inland NW Iberia, where previous paleoecological research is scarce. Extremely sparse and open vegetation composed of steppic grasslands and heathlands with scattered pioneer trees suggests very cold and dry conditions during the Oldest Dryas, unsuitable for tree survival in the surroundings of the study site. Slight woodland expansion during the Bolling/Allerod was interrupted by the Younger Dryas cooling. Pinewoods dominated for most of the early Holocene, when a marked increase in fire activity occurred. Deciduous trees expanded later reaching their maximum representation during the mid-Holocene. Enhanced fire activity and the presence of coprophilous fungi around 6400-6000 cal yr BP suggest an early human occupation around the site. However, extensive deforestation only started at 4500 calyr BP, when fire was used to clear the tree canopy. Final replacement of woodlands with heathlands, grasslands and cereal crops occurred from 2700 cal yr BP onwards due to land-use intensification. Our paleoecological record can help efforts aimed at restoring the natural vegetation by indicating which communities were dominant at the onset of heavy human impact, thus promoting the recovery of currently rare oak and alder stands.

“…From the palaeoenvironmental viewpoint, one of the most important features of the early Holocene is a significant climatic amelioration, with a steady rise in both the temperature and precipitations (Bradley, 1999;Burroughs, 2005;Carri on et al, 2010;Muñoz-Sobrino et al, 2013).…”

a b s t r a c tThe present paper summarises the evolution of the vegetation and the evidences of anthropisation in the Western Pyrenees (Northern Iberian Peninsula) during the Holocene. All the palynological studies published about this region, about both natural and archaeological deposits, have been compiled, and special attention is paid on the available radiocarbon dates. We also present new results of the palynological study of the peat bog of Atxuri (Navarre). The main results document the arboreal colonisation in the early Holocene; the first evidences of anthropisation associated with the Early Neolithic (ca. 5500 e4500 cal BC); the consolidation of a productive economy (agriculture and pastoralism) in the Middle/ Late Neolithic (ca. 4500e3200 cal BC) and above all in the Chalcolithic (ca. 3200e2200 cal BC); and the rise of complex urban societies in the Bronze Age (ca. 2200e900 cal BC) and Iron Age (ca. 900 e200 cal BC) and their impact on the vegetation.
