Lateglacial and Holocene chronology of climate‐driven postglacial landscape evolution in northeast Greenland Open
The Greenland Ice Sheet is highly sensitive to climate change, leading to significant retreat along its edges. This rapid ice loss contributes to rising sea levels and impacts the Earth's climate stability. Understanding the extent of rece…

Assessing the effect of climatic forcing on the landscape evolution of a mountainous setting: A case study of the northern flank of Sierra de Gredos (Central Spain) Open
Glaciers in mountainous landscapes reshape the topography by forming wide-open valleys. Besides valley excavation, the amount of available glaciogenic sediment stored after deglaciation is paramount since this is used by rivers to incise a…

A ∼5000 year multiproxy record of summer climate in NE Greenland Open
The High Arctic plays a vital role in Earth's climate system, and its ecosystems are highly sensitive to global climate change. High Arctic lakes are valuable sentinels of climate change, as their sediments integrate long-term natural clim…

Geomorphological record of the glacial to periglacial transition from the Bølling–Allerød to the Holocene in the Central Pyrenees: the Lòcampo cirque in the regional context Open
In the highest tributaries of the Upper Garonne Basin, Central Pyrenees, cirques up to 2600 m a.s.l. were already deglaciated by 15–14 ka. The long‐term deglaciation during Termination‐1 (T‐1) was interrupted by glacial advances within the…
