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

Electrical Conductivities of Conductors, Semiconductors, and Their Mixtures at Elevated Temperatures

Advanced Engineering Materials, Volume 28, Issue 8, 22 April 2026.
This article presents a comprehensive review of temperature‐dependent electrical conductivity data for multiple material classes at elevated temperatures, highlighting a persistent conductivity gap between metals and semiconductors in the range of 102$\left(10\right)^{2}$– 107$\left(10\right)^{7}$ S/m. Metal–ceramic irregular metamaterials are proposed

Satellite‐Based Detection of Methane Emissions From Permafrost Peatland Warming

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Column‐averaged methane (XCH4) observations spanning 2018–2023 by the Tropospheric Monitoring Instrument (TROPOMI) on the Sentinel‐5 Precursor satellite are assessed for evidence of methane (CH4) emissions from permafrost regions. Bi‐monthly TROPOMI XCH4 anomaly maps and soil temperature (Tsoil) anomaly maps from reanalysis data are generated ...

Mass Addition to Timpanogos Rock Glacier: Debris‐Covered Snow and the Importance of Interannual Variability in Headwall Erosion and Climate

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract The processes of ice incorporation into rock glaciers have been difficult to quantify in both permafrost and non‐permafrost conditions. Here, we develop a numerical model that regardless of the presence of permafrost, reveals how debris eroded from hillslopes and deposited on snow can add ice mass to rock glaciers in pulses.

Northern Eurasia Future Initiative (NEFI): facing the challenges and pathways of global change in the twenty-first century [PDF]

, 2017
During the past several decades, the Earth system has changed significantly, especially across Northern Eurasia. Changes in the socio-economic conditions of the larger countries in the region have also resulted in a variety of regional environmental ...

Multi‐Scale Drivers of Food‐Water‐Energy Related Ecosystem Services in the Context of Land Degradation: Insights From the Beijing‐Tianjin‐Hebei Agglomeration

Land Degradation &Development, Volume 37, Issue 6, Page 2058-2083, 15 April 2026.
ABSTRACT Land degradation poses significant challenges to maintaining food–water–energy (FWE) security, particularly in rapidly urbanizing regions. The ecosystem services (ES) related to FWE are critical for sustainable regional development. Yet, rapid urbanization in the Beijing–Tianjin–Hebei region has altered land use and ecological patterns ...

Why, Immunologically, Housing‐Related Fungi and Endotoxins (and Other Chronic Pro‐Inflammatory Stressors) Risk Latent Tuberculosis Reactivation, Severe Asthma, and Translocating and Invasive Infections in Indigenous Communities in Canada

American Journal of Human Biology, Volume 38, Issue 4, April 2026.
ABSTRACT Type 1/M1/TH1 and type 3/M1/TH17 pro‐inflammatory switches are risks for latent Mycobacterium tuberculosis (Mtb) reactivation and ongoing infection transmission. This paper considers the heavy toll of reactivation risk in Indigenous communities in Canada and the chronic, everyday pro‐inflammatory stressors connected with type 3/M1/TH17 immune ...
