November 27, 2012 Policy Implications of Warming Permafrost Kevin Schaefer Ted Schuur Dave McGuire
Focus Discussion on Report • United Nations Environment Programme (UNEP) • Nov 2012 at Doha Conference of Parties (CoP) • Authors • Coordinator: Ron Witt • Kevin Schaefer • HuguesLantuit • Vladimir E. Romanovsky • Edward A. G. Schuur • http://www.unep.org/pdf/permafrost.pdf
Impact of Thawing Permafrost on Global Climate • ~1700 Gt of carbon in permafrost as frozen organic matter • Thawing permafrost will release CO2 and methane into atmosphere
The Permafrost Carbon Feedback • Amplifies surface warming • Irreversible • Emissions for centuries Projected annual permafrost emissions for A1B scenario
Estimates of Permafrost Fluxes a CO2 equivalent calculated assuming 2.7% of total emissions is methane (Schuur et al. 2011) and a global warming potential of 33 (Shindell et al. 2009) b calculated from emission rates in the paper c not available
Impact on Climate Change Treaty • 2°C warming target • Account for permafrost emissions • AR5 Projections don’t include permafrost emissions • Temperatures higher with feedback • Emissions targets may be too high • Risk overshooting 2°C warming target Temperature Projections 4th Assessment Report
Recommendation 1: Special IPCC report on permafrost emissions • IPCC special assessment report • Future permafrost degradation • Permafrost CO2and methane emissions • Projections with permafrost carbon feedback • Complement current projections • Support negotiation of emissions targets
Recommendation 2: Create National permafrost monitoring networks • Issue: Current networks not adequate • Take over TSP/CALM • increase funding • standard measurements • expand coverage • All countries, especially Russia, Canada, China, United States Circumpolar Active Layer Monitoring (CALM) Thermal State of Permafrost (TSP)
Recommendation 3: Plan for adaptation • Issue: No plans to address infrastructure impacts • Nations should develop adaptation Plans • Identify at-risk infrastructure • Evaluate risks, costs, mitigation • All countries, especially Russia, Canada, China, United States
Breakout Objectives • How to implement recommendations? • Special IPCC Assessment • Nationalize CALM and TSP • Adaptation Plans • Focus on (1) • International Permafrost Association will focus on (2) and (3) • All suggestions welcome
Questions to consider • How to make special assessment a priority? • Who should we talk to? • Which agencies should be involved? • How should science community be organized? • What should the special assessment include?

Permafrost is permanently frozen ground • Occurs in 24% of Northern Hemisphere land
