Freshwater and carbon export to northern Alaska estuaries increased
Model-based analysis reveals intensified freshwater and organic carbon discharge to northern Alaska’s Beaufort Sea estuaries driven by permafrost thaw and hydrological cycle changes.
Ice- and peat-rich permafrost degraded gradually on Eboling Ridge
Organic-rich permafrost on China’s Qilian Eboling Ridge degrades slowly due to ice-carbon coupling that provides thermal insulation, reducing climate sensitivity compared to mineral-dominated regions.
Old dissolved carbon from permafrost thaw accumulates in Siberian lakes
Study reveals that up to 75% of dissolved organic carbon in Siberian thermokarst lakes originates from permafrost thaw, yet this ancient carbon accumulates rather than rapidly converting to.
