Global Hydroclimatic Controls on Multithread River Dynamics

AGU Advances, Volume 7, Issue 2, April 2026.
Abstract Most large rivers in densely populated areas split flow into multiple channels, forming interconnected pathways called threads. Multithread rivers are sensitive to hydroclimatic changes, yet understanding their dynamics is challenging due to the lack of robust metrics to characterize their evolution.

Impact of Fire and Heat Stress on Soil Microorganisms: A Review of Community Changes, Molecular Responses and Plant‐Beneficial Roles

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.
This work reviewed the direct and indirect effects of fires on microbial communities and the resilience strategies microbes use to withstand high temperatures . ABSTRACT Fire, whether occurring on the surface or underground, significantly influences soil microbial dynamics by reshaping community composition, functional diversity and overall soil and ...

Using Texture‐Based Image Segmentation and Machine Learning With High‐Resolution Satellite Imagery to Assess Permafrost Degradation Landforms in the Russian High Arctic

Journal of Geophysical Research: Machine Learning and Computation
Amplified climate change across the Arctic causes significant permafrost thaw and an increase of permafrost degradation landforms. These landforms range from fine‐scale degrading ice wedge‐polygon‐networks to large‐scale features such as thermo‐erosional

Decoupling Hydroclimatic Controls on Displacement of Retrogressive Thaw Slumps in Qinghai‐Tibet Plateau

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract The retrogressive thaw slumps (RTS), a prevalent form of thermokarst hazard in permafrost regions, are increasing in both number and extent under contemporary changing environments. On the Qinghai‐Tibet Plateau, RTS threaten transportation infrastructure and disrupt ecosystems.

Inverse Grading Emerges From Particle‐Scale Migration Under Seasonal Freeze‐Thaw Forcing: Evidence From Multi‐Year Monitoring and Physical Modeling

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Inverse grading, where coarse particles overlay finer materials, is common on talus slopes, yet its progressive formation under realistic conditions is rarely quantified. We integrate multi‐year field observations with controlled freeze‐thaw experiments to elucidate the processes driving particle migration that result in inverse grading and ...

Trophic Changes off Southwest Greenland During the Holocene and Their Influence on Carbon Burial

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Organic carbon (OC) burial in sediments is partly controlled by catabolic biodegradation and remineralization by heterotrophic bacteria, but long‐term records of these bacterially‐mediated processes have not been available. Here, we use stable hydrogen isotope ratio of the saturated C16 fatty acid (δ2HC16:0) as a proxy of the prevalence of ...

How Does Fluid Exchange Between Pores in Unsaturated Porous Media?

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract The inter‐pore fluid exchange, driven by molecular diffusion, is referred to as pore coupling. The pore coupling affects subsurface pore‐scale physicochemical dynamics. Monitoring pore coupling is essential for understanding numerous hydrological and ecological processes.

DARTS: Multi-year database of AI-detected retrogressive thaw slumps in the circum-arctic permafrost region

Scientific Data
Retrogressive Thaw Slumps (RTS) are widespread mass-wasting hillslope failures triggered by thawing permafrost. While regional studies have provided insights into the spatial distribution and dynamics of RTS, a consistent and unbiased quantification and ...

Rainfall and Rain‐on‐Snow Events Over Greenland in Summer: Climatology, Trends, Synoptics

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract Rain‐on‐snow (ROS) events in the Arctic can lead to major impacts on the snow cover, cryosphere and environment. During the last decades, these events have significantly increased, mostly due to climate change. Here, we use outputs from the regional climate model MAR (version 3.14) driven by the ERA5 reanalysis at 10‐km resolution over ...
