Untold Stories: Indigenous Knowledge Beyond the Changing Arctic Cryosphere

Frontiers in Climate, 2021
Scientific attention to climate change in the Arctic has spurred extensive research, including many studies of Indigenous knowledge and the effects of climate change on Indigenous peoples. These topics have been reported in many scientific papers, books,

Evaporation From Soil and Thermokarst Lakes Contribute More to Local Precipitation Than Plant Transpiration in Permafrost Regions of the Central Qinghai—Tibet Plateau

Water Resources Research, Volume 61, Issue 11, November 2025.
Abstract Permafrost degradation on the Qinghai—Tibet Plateau (QTP) directly affects evapotranspiration and moisture recycling processes by changing the underlying land surface conditions. However, the contributions of thermokarst lake evaporation and plant transpiration to local precipitation in permafrost regions of the QTP remain unknown.

Arctic Sea Ice Seasonal Melt‐Freeze Transitions Observed by ASCAT From 2007 to 2022

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 20, 28 October 2025.
Abstract Seasonal melt‐freeze transitions of Arctic sea‐ice play a vital role in Arctic climate patterns. They are detectable by satellite remote sensing. In this study, we present a sea ice type‐independent machine learning algorithm using Advanced Scatterometer (ASCAT) data at 4.45 km resolution, offering a means to complement melt‐freeze onset ...

A Tool to Assess the Accuracy of Glacial Isostatic Adjustment Predictions of Present‐Day Crustal Uplift Rates

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.
Abstract Ongoing glacial isostatic adjustment (GIA) is detectable in geodetic height time series and changes in the temporal gravity field. Global GIA models are often used to remove these signals from data but quantifying the errors in such models is difficult due to insufficient knowledge of Earth rheology and past ice history.

The research station "Vaskiny Dachi", Central Yamal, West Siberia, Russia – a review of 25 years of permafrost studies

Fennia: International Journal of Geography, 2015
The research station "Vaskiny Dachi" on the Yamal Peninsula was established in 1988. Activities aimed at monitoring of permafrost and related environmental features under a relatively low level of nature disturbances caused by gas field development ...

Estimating the Impact of Impounding an 85‐km2 Hydropower Reservoir in a Subarctic Environment on the Local Radiation Balance

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 20, 28 October 2025.
Abstract This study focuses on the net radiative forcing caused by the impoundment of an 85‐km2 hydroelectric reservoir in the subarctic Côte‐Nord, Quebec, Canada (50.69°N, 63.24°W, mean depth of 44 m). Using spectral bands from the Landsat 7 ETM+ and Landsat 8 OLI/TIRS satellites, we observed spatial and temporal variations in albedo and surface ...

Atmospheric Tides Cause Semidiurnal Variation of Marine Air Temperature

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract Surface marine air temperature (MAT) is a fundamental variable in weather and climate applications. However, non‐aspirated MAT sensors, commonly used on ocean observing platforms due to power constraints, often experience radiative heating when the sun is low, producing secondary mid‐morning and mid‐afternoon peaks typically considered ...

Recent Change—Terrestrial Cryosphere [PDF]

, 2015
This chapter compiles and assesses information on recent and current change within the terrestrial cryosphere of the Baltic Sea drainage basin. Findings are based on long-term observations. Snow cover extent (SCE), duration and amount have shown a widespread decrease although there is large interannual and regional variation.

Thermohaline Preconditioning for Sea Ice Formation in the Beaufort Sea

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract The influence of ocean stratification and heat content on the timing of sea ice formation and its subsequent growth remains an open question. Here we investigate the thermohaline conditions prior to fall sea ice formation as well as the roles of stratification and heat content on sea ice growth rates through the analysis of in situ ...

Ice Sheets Without Dynamic Topography

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract Dynamic topography results in uplift and subsidence events on Earth's surface with amplitudes on the order of a kilometer. These vertical motions are known to have influenced ice sheet evolution, but how dynamic topography has controlled the current state of present ice sheets is unknown.
