New synthesis on abrupt thaw and carbon Published in Nature Geoscience

(February 2020)

The newest synthesis of the Permafrost Carbon Network got published in Nature Geoscience.

This synthesis provides a first estimate of thermokarst (abrupt thaw) carbon emissions using numerical models. Abrupt thaw occurs in <20% of the permafrost zone but could double permafrost carbon emissions.

New winter CO2 flux synthesis published in Nature Climate Change

(October 2019)

The newest synthesis of the Permafrost Carbon Network got published in Nature Climate Change.

Natali et al. write: Our results provide a baseline for winter CO2 emissions from northern terrestrial regions and indicate that enhanced soil CO2 loss due to winter warming may offset growing season carbon uptake under future climatic conditions.

Permafrost collapse is accelerating carbon loss

(April 2019)

A new Nature Comment authored by Merritt Turetsky and members of the Permafrost Carbon Network shows that a sudden collapse of thawing soils in the Arctic might double the warming from greenhouse gases released from tundra.

New Synthesis on soil thermal regimes in permafrost

(August 2018)

Vegetation and soils strongly influence ground temperature in permafrost ecosystems across the Arctic and sub-Arctic. These effects will cause differences rates of permafrost thaw related to the distribution of tundra and boreal forests. As the distribution of forests and tundra change, the effects of climate change on permafrost will also change. We review the ecosystem processes that will influence permafrost thaw and outline how they will feed back to climate warming.

New Permafrost model intercomparison published

(April 2018)

The results from this model intercomparison suggest that effective mitigation efforts during the remainder of this century could attenuate the negative consequences of the permafrost carbon–climate feedback.
