Wildfires offset the increasing but spatially heterogeneous Arctic–boreal CO₂ uptake

How the carbon stocks of the Arctic–Boreal Zone change with warming is not well understood. Here the authors show that wildfires and large regional differences in net carbon fluxes offset the overall increasing CO₂ uptake.

Seasonal increase of methane emissions linked to warming in Siberian tundra

The authors provide long-term observational evidence of an increasing trend of early summer methane emissions from a permafrost site in the Lena River Delta linked to atmospheric warming. This observed trend constitutes a major development given the thick and cold permafrost in the study area.

Decadal increases in carbon uptake offset by respiratory losses across northern permafrost ecosystems

The future of carbon dynamics in the northern high latitudes is uncertain yet represents an important potential feedback under climate change. This study uses a comprehensive observational dataset to show an increasing carbon sink in non-permafrost systems; in permafrost systems uptake was offset by loss.

Temperature thresholds of ecosystem respiration at a global scale

The authors test for temperature dependency of ecosystem respiration rates across globally distributed eddy covariance sites, revealing consistent temperature thresholds where ecosystem metabolism changes.

Vegetation type is an important predictor of the arctic summer land surface energy budget

An international team of researchers finds high potential for improving climate projections by a more comprehensive treatment of largely ignored Arctic vegetation types, underscoring the importance of Arctic energy exchange measuring stations.

Substantial hysteresis in emergent temperature sensitivity of global wetland CH₄ emissions

Wetland methane emissions contribute to global warming, and are oversimplified in climate models. Here the authors use eddy covariance measurements from 48 global sites to demonstrate seasonal hysteresis in methane-temperature relationships and suggest the importance of microbial processes.

Large loss of CO₂ in winter observed across the northern permafrost region

Winter warming in the Arctic will increase the CO₂ flux from soils. A pan-Arctic analysis shows a current loss of 1,662 TgC per year over the winter, exceeding estimated carbon uptake in the growing season; projections suggest a 17% increase under RCP 4.5 and a 41% increase under RCP 8.5 by 2100.

Temporally dynamic carbon dioxide and methane emission factors for rewetted peatlands

Rewetting of a fen peatland site in Germany has led to a source-to-sink transition of annual carbon dioxide, a decreasing trend in methane fluxes and temporally dynamic emission factors, according to long-term eddy covariance observations.
