Arctic permafrost stores nearly 1,700 billion metric tons of frozen and thawing carbon.
Anthropogenic warming threatens to release an unknown quantity of this carbon to the …

Tundra vegetation productivity and composition are responding rapidly to climatic changes
in the Arctic. These changes can, in turn, mitigate or amplify permafrost thaw. In this Review …

Abstract The Russian invasion of Ukraine hampers the ability to adequately describe
conditions across the Arctic, thus biasing the view on Arctic change. Here we benchmark the …

The regional variability in tundra and boreal carbon dioxide (CO2) fluxes can be high,
complicating efforts to quantify sink‐source patterns across the entire region. Statistical …

Despite the importance of high-latitude surface energy budgets (SEBs) for land-climate
interactions in the rapidly changing Arctic, uncertainties in their prediction persist. Here, we …

Field-measured soil respiration (RS, the soil-to-atmosphere CO 2 flux) observations were
compiled into a global soil respiration database (SRDB) a decade ago, a resource that has …

Plant biomass is a fundamental ecosystem attribute that is sensitive to rapid climatic
changes occurring in the Arctic. Nevertheless, measuring plant biomass in the Arctic is …

Past efforts to synthesize and quantify the magnitude and change in carbon dioxide (CO 2)
fluxes in terrestrial ecosystems across the rapidly warming Arctic-Boreal Zone (ABZ) have …

Large changes in the Arctic carbon balance are expected as warming linked to climate
change threatens to destabilize ancient permafrost carbon stocks. The eddy covariance (EC) …

Accurate simulations of high‐latitude ecosystems are critical for confident Earth system
model (ESM) projections of carbon cycle feedbacks to global climate change. Land surface …
