C and N Isotopic Fractionation Along Permafrost Profiles: A Theoretical Framework and Empirical Tests Across the Arctic

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 7, July 2026.
Abstract Anticipating the decomposition of permafrost organic matter (OM) following thaw is critical for improving projections of climate‐carbon feedbacks. Stable carbon (C) and nitrogen (N) isotope profiles provide integrated records of the environmental and biogeochemical processes that shaped OM during its accumulation and may therefore improve our ...

Decline in Ice Coverage and Ice-Free Period Extension in the Kara and Laptev Seas during 1979–2022

Remote Sensing
The duration of ice-free periods in different parts of the Arctic Ocean plays a great role in processes in the climate system and defines the most comfortable sea ice conditions for economic activity. Based on satellite-derived sea ice concentration data

Effects of Wintertime Snow Depth Assimilation on Summertime Sea Ice Prediction Experiments Utilizing a Fully Coupled Regional Arctic Model With Perfect Boundary Conditions

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 7, July 2026.
Abstract During the past decades, the rapid decline of sea ice in the Arctic Ocean has substantially favored commercial navigation activities in the summertime. Numerical sea ice prediction on a seasonal scale plays a crucial role in guiding the programme of such activities, yet the role of snow depth data assimilation in numerical sea ice prediction ...

Slowed Rossby Wave Phase Speed Over Siberia Linking Arctic Warm Conditions to Mid‐Latitude Cold Anomalies

Earth's Future, Volume 14, Issue 7, July 2026.
Abstract The influence of Arctic warming on mid‐latitude cold extremes remains a subject of active debate, with the role of Rossby wave propagation emerging as a key aspect warranting investigation. Here, we examine wintertime Rossby wave phase speed changes over Siberia and their relationship with Arctic warm conditions on intraseasonal timescales. We

Changes in Arctic Sea Ice Lead Width Distribution: Model Development and Experiments

Journal of Geophysical Research: Oceans, Volume 131, Issue 7, July 2026.
Abstract Sea ice leads play a significant role in the atmosphere‐sea ice‐ocean systems. Model representation of leads of varying widths is desirable to enhance our understanding of the behavior of leads and associated processes. We have developed a lead width distribution (LWD) conservation equation to explicitly simulate the evolution of leads of ...

Terrestrial sources of summer arctic moisture and the implication for arctic temperature patterns

npj Climate and Atmospheric Science, 2021
Sea ice melt and ocean heat accumulation in the Arctic are strongly influenced by the presence of atmospheric water vapor during summer. While the relationships between water vapor concentration, radiation, and surface energy fluxes in the Arctic are ...

Enhanced Solar Radiation Attenuation in the Arctic Shelf Driven by Warming‐Induced Terrestrial Inputs

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Arctic warming accelerates permafrost thaw and coastal erosion, increasing terrestrial material transport to the ocean. Using Moderate Resolution Imaging Spectroradiometer (MODIS) data (2002–2023), we report a widespread increase in the diffuse attenuation coefficient Kd(490) across Arctic shelves since 2018, notably in the Laptev and Kara ...

Deployment Strategy Shapes the Polar Climate Response to Marine Cloud Brightening

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.
Abstract Marine cloud brightening (MCB) is a proposed solar climate intervention strategy that increases marine cloud reflectivity to cool Earth's surface. While previous studies have largely examined its global temperature and precipitation effects, little is known about how MCB deployment strategies influence polar climate and sea ice.
