Increasing Warming May Inhibit Land Carbon Uptake in Northern High Latitudes

open access: yesGeophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Arctic ecosystems are warming at an accelerated rate, with heatwaves becoming more frequent and intense. We examined productivity responses of Arctic ecosystems to major warming events from 2000 to 2022. Results indicated that early‐season warming generally enhances productivity, whereas prolonged high temperatures suppress productivity later ...

Three‐Fourths of Carbon Emissions From 2023 Record‐Breaking Wildfires in Canada Traced to Soil and Peat Combustion

open access: yesGeophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract In 2023, wildfires burned vast areas in Canada, emitting large amounts of carbon (C). The area burned by the 2023 wildfires is the largest ever recorded in Canada, but the partitioning of C emissions between aboveground biomass and soil sources remains unknown.

Substantial Accumulation of Chemically Oxidizable Organic Carbon in Continental Margin Sediments

open access: yesGeophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract The balance between organic carbon (OC) sequestration and oxidation regulates the oceanic carbon cycle, and OC reactivity determines its susceptibility to remineralization or long‐term burial. However, the stability of sedimentary OC on continental margins remains poorly understood.

Hydrological Threshold for Optimizing Wetland Climate Mitigation

open access: yesGeophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Wetland carbon cycling reflects an intrinsic balance between CO2 sequestration and anaerobic methane production, though hydrological drivers remain insufficiently quantified. Here, we synthesize eddy covariance data from 43 natural wetlands spanning diverse climates and hydrological regimes to quantify greenhouse gas (GHG) responses to water ...

Experimental Proof to Natural Hydrogen Generated Through Serpentinization of Olivine at Room Temperature and Ambient Pressure With Mechanochemistry

open access: yesChemSusChem, Volume 19, Issue 13, 14 July 2026.
This work shows experimentally the possibility of serpentinization (main mechanism of natural hydrogen) at room temperature and ambient pressure, which may provide the rapidly growing hydrogen economy with inspirations to explore new natural hydrogen deposits and new methods for hydrogen production. Natural hydrogen, or “white hydrogen,” is a promising
