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…

Extreme Arctic lakes reveal accelerating ecological shifts linked to 21st century warming Open
The Arctic is among the most rapidly warming regions on Earth, and climate change has triggered widespread alterations to its cryosphere and ecosystems. Among these, extreme northern lakes are highly sensitive to rising temperatures due to…

Projected climate change will double the Late Holocene maximum to present ice loss in Central-Western Greenland by 2070 Open
Greenland's peripheral glaciers and ice caps (GICs) have experienced accelerated mass loss since the 1990s. However, the extent to which present and future trends of GICs are unprecedented within the Holocene is poorly understood. This stu…

Cryosphere degradation in a changing climate Open
Over the last few decades, the instrumental climate record shows a progressive global warming. As one of the most sensitive elements of the Earth's climate system, the cryosphere is significantly affected by this trend. As a result, its va…

Glacier ice loss in Central-Western Greenland from last-millennium maximum to present Open
The melting of snow and ice in Greenland has accelerated since the 1990s, resulting in significant impacts on the ecosystem, such as sea-level rise. However, the spatiotemporal evolution of Greenland's peripheral glaciers and ice caps (GIC…

Rising Extreme Meltwater Trends in Greenland Ice Sheet (1950–2022): Surface Energy Balance and Large-Scale Circulation Changes Open
The Greenland Ice Sheet (GrIS) meltwater runoff has increased considerably since the 1990s, leading to implications for the ice sheet mass balance and ecosystem dynamics in ice-free areas. Extreme weather events will likely continue to occ…

Contrasting glacier terminus position trend rates between Central-Western Greenland peripheral glaciers and ice sheet:  spatiotemporal patterns and trends (1985 to 2022) Open
Greenland's snow and ice melting trends have increased since the conclusion of the Little Ice Age (LIA), leading to the emergence of new ice-free zones. Given its significant impacts on ecosystems and climate, a comprehensive understanding…

Rain-on-snow responses to warmer Pyrenees: a sensitivity analysis using a physically based snow hydrological model Open
Climate warming is changing the magnitude, timing, and spatial patterns of mountain snowpacks. A warmer atmosphere may also induce precipitation phase shifts, resulting in a decreased snowfall fraction (Sf). The combination of Sf and snowp…

Evidence of summer thermal stratification in extreme northern lakes Open
Rapid warming in the High Arctic has induced changes in terrestrial environments that have included major recent shifts in lakes and ponds. Numerous studies exist of spatial trends in water chemistry, bioindicator groups, and paleoenvironm…

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…
