SEARCH International Methane Budgets Workshop

The International Workshop to Reconcile Northern Permafrost Methane Budgets will be held 7-9 March 2017 in Seattle, Washington. Information on workshop objectives, expected products, agenda, participants, and other information is available on the Workshop website at: https://www.arcus.org/search-program/permafrost/methane-workshop

Call for Abstracts for AGU Session

The Permafrost Action Team is hosting a session at AGU:
Session Title: (B096) Vulnerability of Permafrost Carbon to Climate Change
This session invites papers that examine factors causing losses and gains in ecosystem carbon storage relating to the magnitude, timing and form of carbon release from permafrost. Papers may address any aspect of this topic from microbial communities to the global scale, using a range of measurements or modeling to detect and forecast permafrost thaw and the influence on the carbon cycle and future climate.

Session conveners:
Christina Schaedel, Northern Arizona University
Claire Treat, USGS
Ted Schuur, Northern Arizona University
Please consider submitting your abstract to our session. Abstract submission deadline is Wednesday, August 3, 2016.

Permafrost Carbon Network Updates

Upcoming Annual Permafrost Carbon Network Meeting

The annual Permafrost Carbon Network meeting takes place on the Sunday (December 11) before the American Geophysical Union Fall Meeting in San Francisco. Tentative meeting times are 9:00 am to 5:00pm. The meeting is open to new network participants.

Synthesis Leads Meeting

The Permafrost Carbon Network had a successful meeting for synthesis leads and co-leads the weekend before XI. ICOP in Potsdam, Germany (June 18-19). Synthesis leads gave short presentations and updated the group on synthesis progress. All presentations are made available online to signed up participants of the Permafrost Carbon Network on Google Drive through this link. There are always opportunities to get involved in these ongoing synthesis activities and we encourage you to have a look at the short presentations and to get in touch with the corresponding lead if you have data to share or are interested in participating. The full meeting agenda and a list of participants can be found online: http://www.permafrostcarbon.org/past%20meetings.html

Permafrost Carbon Network 5-Year Synthesis Report

Three major science synthesis efforts assessing the climate feedback from permafrost carbon are highlighted in this new report from the Permafrost Carbon Network. In addition to these science highlights, the report provides further details on the Permafrost Carbon Network workshops, public outreach activities, and the PCN's highly successful effort to build an engage a productive Arctic change research community.
