Severe Arctic Permafrost Thaw Accelerating Global Climate and Human Risks
Recent Developments
01NOAA Arctic Report Card 2025 (released 2025) documents record warmth and wetness, thawing permafrost releasing iron and metals into rivers
02Comprehensive Alaska permafrost thaw database released (preprint 2025) with 19,540 locations spanning 1950-present
03Study (Sep 2025) shows 2°C warming enhances Arctic permafrost GHG sink but weakens alpine sinks
Interventions
- Permafrost thaw database for Alaska used to inform climate mitigation, adaptation strategies, and ground ice mapping
- NOAA Arctic Report Card tracking changes to guide policy and research on thaw impacts
What Works
- High-resolution spatial databases like Alaska's thaw dataset improve predictive modeling and field campaign targeting
- Integrated data synthesis from 1,090 sites reveals regional GHG responses to warming, aiding targeted interventions
How to Help
- Support research organizations like NOAA Arctic program
- Advocate for permafrost monitoring and adaptation funding
- Contribute to citizen science on Arctic environmental changes

IARPC's Collaborations Risk Team hosts webinars featuring PDG data, enabling federal agencies to use geospatial tools for permafrost risk assessment. They facilitate integration of thaw impacts into policy, focusing on infrastructure, community relocation, and emissions monitoring.
Woodwell’s Permafrost Pathways program conducts field measurements, synthesis, and model‑integration to quantify greenhouse gas emissions from thawing permafrost and to translate those results for policy. They operate Arctic field campaigns (soil carbon and greenhouse gas flux measurements), compile and analyze permafrost carbon inventories, develop process understanding to inform Earth system models, and produce policy‑relevant syntheses and briefings to ensure permafrost emissions are included in national and international climate assessments and policy frameworks.
NSIDC supports and publishes research synthesizing observations and model results on permafrost thaw and its climate feedbacks, maintains and distributes long‑term cryosphere datasets used to track thaw and subsidence, and issues science communications and press releases that make permafrost impacts accessible to policymakers and the public. NSIDC scientists collaborate on modeling studies that quantify carbon release from permafrost and help integrate those findings into broader climate assessments.
USGS monitors and documents groundwater decline and depletion through extensive networks of observation wells, publishing data on water level changes, saturated thickness reductions, and aquifer status. They develop tools like MODFLOW for simulating groundwater flow to predict impacts of extraction and support sustainable management strategies nationwide.
