Rapid Arctic environmental change affects the entire Earth system as thawing permafrost
ecosystems release greenhouse gases to the atmosphere. Understanding how much …

Climate warming threatens to destabilize vast northern permafrost areas, potentially
releasing large quantities of organic carbon that could further disrupt the climate. Here we …

Protecting or restoring aquatic ecosystems in the face of growing anthropogenic pressures
requires an understanding of hydrological and biogeochemical functioning across multiple …

Reconstructing climates of the past relies on a variety of evidence from a large number of
sites to capture the varied features of climate and the spatial heterogeneity of climate …

Carbon cycle models suggest that past warming events in the Arctic may have caused large-
scale permafrost thaw and carbon remobilization, thus affecting atmospheric CO2 levels …

The organic-carbon (OC) pool accumulated in Arctic permafrost (perennially frozen ground)
equals the carbon stored in the modern atmosphere. To give an idea of how Yedoma region …

The collapse of the steppe-tundra biome (mammoth steppe) at the end of the Pleistocene is
used as an important example of top-down ecosystem cascades, where human hunting of …

Radiocarbon dated chronologies are the most extensively applied dating technique when
investigating the last∼ 45,000 years. In lake and marine sediments, a single macrofossil or …

Recent hypotheses, based on atmospheric records and models, suggest that permafrost
carbon (PF-C) accumulated during the last glaciation may have been an important source …

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 …
