, 2021 Since the middle of the 19th century, the Earth has experienced a climate shift marked by a high rise in temperature (+ 0.85 °C over the period 1880-2012). The Arctic is the region of the world that is warming the most rapidly, at a rate of 2 to 3 times faster than the global average.

Hidden subsurface suspended sediment export from Greenland's marine‐terminating glaciers
Limnology and Oceanography Letters, Volume 11, Issue 6, November 2026.Abstract Runoff and calved ice volumes from the Greenland Ice Sheet are well constrained, but quantifying the associated suspended sediment flux remains challenging. Here we present near‐terminus observations from three glacierized fjords in southeast Greenland, combining full‐depth turbidity profiles and current velocity from summer 2024 to evaluate ...

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 11, November 2026.Abstract Open bedrock fractures are common features in unstable rock slopes and alter subsurface thermal conditions of fractured rock masses through convective air ventilation and atmospheric exchange. These processes are particularly relevant in cold mountain environments, where variations in ground temperature affect rock mass stability and may allow

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.Abstract Extratropical cyclones strongly influence Arctic sea ice thermodynamics through episodic heat and moisture transport, yet their thickness‐dependent impacts remain poorly quantified. Using comprehensive observations from the Multidisciplinary Drifting Observatory for the Study of Arctic Climate (MOSAiC), we investigate how sea ice thickness ...

Why April Stands Out: Monthly Impacts of Internal Variability on Arctic Amplification
Journal of Geophysical Research: Atmospheres, Volume 131, Issue 19, 16 October 2026.Abstract Observed Arctic amplification (AA), defined as the ratio of Arctic‐mean to global‐mean surface air temperature (SAT) trends, peaks in April, a feature not captured by climate models. Here, we quantify the impact of internal variability on Arctic‐mean SAT trends in March, April, and May from 1980 to 2022 using multiple approaches, including ...

Japanese glaciological activities in the Arctic region (report)
Japanese glaciological activities in the Arctic region (report)P(論文) The objectives of the Japanese Arctic Glaciological Expedition were to study the regional characteristics of glacier processes and the climatic and environmental changes for the last few hundred years in the Arctic cryosphere. During 1987-1996,glaciological observation and shallow ice core drilling were carried out at various places such as the ...
