Anthropogenic interference and climatic change control long‐term dissolved silicate variation in the Yellow River

Limnology and Oceanography Letters, Volume 11, Issue 2, March 2026.
Abstract Dissolved silicate (DSi) export from rivers is shaped by both natural processes and human activities. Using long‐term observations at Lijin station combined with chemical weathering and reservoir silicon cycling models, we reconstructed annual DSi fluxes and source‐sink dynamics in the Yellow River Basin since the 1980s.

Climate Shapes the Ratio Between Aboveground Plant Biovolume and Topsoil Macronutrients Worldwide

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 1, March 2026.
ABSTRACT Soil nutrients are a major limiting factor for plant biomass, yet paradoxically, some of the most productive ecosystems thrive in nutrient‐poor soils. Here, we conducted a global field survey in 421 sites across all major biomes to investigate the environmental factors controlling the ratio between plant biovolume (a proxy for aboveground ...

Frozen Soil Hydrological Processes and Their Effects: A Review and Synthesis

Reviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract Frozen soils, including seasonally frozen ground and permafrost, are rapidly changing under a warming climate, with cascading effects on water, energy, and carbon cycles. We synthesize recent advances in the physics, observation, and modeling of frozen‐soil hydrology, emphasizing freeze–thaw dynamics, infiltration regimes and preferential flow,

Capturing Grasslands in Nationally Determined Contributions and Integrated Assessment Models: Review and Perspective

Earth's Future, Volume 14, Issue 3, March 2026.
Abstract Grasslands support the majority of global livestock production systems while providing vital ecosystem services. Expansion of the livestock sector over recent decades has however placed enormous pressure on grasslands, with increasing greenhouse gas emissions that challenge the aspirations of climate mitigation.

The Arctic Coastal Erosion Model: Overview, Developments, and Calibration at Drew Point, Alaska

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 3, March 2026.
Abstract Permafrost coastlines are experiencing significant erosion as polar amplification has enhanced the effects of climate change in the Arctic. Warmer temperatures are increasing thermo‐denudation and more energetic oceans are increasing thermo‐abrasion in unlithified, ice‐bonded permafrost coastlines which comprise at least 40% of the circum ...
