Permafrost regions at high latitudes and altitudes store about half of the Earth's soil organic
carbon (SOC). These areas are also some of the most intensely affected by anthropogenic …

Many of the world's rivers are ice‐covered during winter months but increasing evidence
indicates that the extent of river ice will shift substantially as winters warm. However, our …

Hydrological transformations induced by climate warming are causing Arctic annual fluvial
energy to shift from skewed (snowmelt-dominated) to multimodal (snowmelt-and rainfall …

Climate change is intensifying the Arctic hydrologic cycle, potentially accelerating the
release of carbon and nutrients from permafrost landscapes to rivers. However, there are …

Climate change is creating widespread ecosystem disturbance across the permafrost zone,
including a rapid increase in the extent and severity of tundra wildfire. The expansion of this …

Mineral elements bind to dissolved organic carbon (DOC) in permafrost soils, and this may
contribute to the stabilization or the degradation of organic carbon along the soil to river …

Riverine exports of silicon (Si) influence global carbon cycling through the growth of marine
diatoms, which account for∼ 25% of global primary production. Climate change will likely …

Climate change is an existential threat to the vast global permafrost domain. The diverse
human cultures, ecological communities, and biogeochemical cycles of this tenth of the …

Arctic rivers are sensitive to climate and environmental change, but the biogeochemical
response remains poorly understood. Monthly size‐fractionated dissolved organic matter …

While over 99% of coastal arctic rivers drain small catchments, future projections of land-
ocean fluxes are based on data from large rivers. We encourage inclusion of and increased …
