Here are some upcoming deadlines and news items that we would like to share with our network:

1) Poster abstracts are due May 20 for 'Arctic Futures 2050 Conference': This novel conference of Arctic scientists, Indigenous People, and policy makers jointly explores the knowledge needed to inform decisions concerning the Arctic in coming decades.

4-6 September 2019,Washington, DC

Conference Agenda Updates:The Arctic Futures 2050 Conference website has been udpated with the latest agenda and speaker updates

  • Poster Abstracts Deadline: 20 May 2019
  • Travel Award Applications Deadline: 20 May 2019
  • Conference Registration: early bird registration through 10 July 2019

 

2) Permafrost collapse is accelerating carbon release: This new Comment in Nature focuses on how large swaths of permafrost in the Arctic are collapsing and leading to abrupt thaw, a phenomenon and feedback current climate models have not accounted for. This work is a product of the Permafrost Carbon Network and the Study of Environmental Arctic Change. The authors call for better data gathering, support of global monitoring sites, incorporation into reports for policymakers and the development of holistic models.

 

3) Join the new IPA Permafrost and Carbon budgets Interest Group (IPaC):

The aim of the IPaC is to impact and improve how permafrost is treated in carbon budgets. IPaC will create and sustain a formalized pathway for IPA permafrost experts to give feedback on the representation of permafrost in datasets used for broad-scale carbon budgets. IPaC is led by a Steering Committee chaired by Dr. Gustaf Hugelius. See here for more information on the Interest Group.

Contact: Justine Ramage, Scientific coordinator IPaC
