Arctic coastal erosion significantly impacts the global carbon cycle and Earth's climate
the verdict
SUPPORTED
the evidence backs this
confidence 88/100
Evidence strongly supports the claim that Arctic coastal erosion significantly impacts the global carbon cycle and Earth's climate by releasing massive amounts of previously frozen organic carbon into active marine and aquatic systems, thereby fueling greenhouse gas emissions and positive climate feedbacks.

Paper 2 shows that lateral thermo-erosion in Arctic landscapes increases the transfer of soil organic matter to aquatic systems, leading to high greenhouse gas emissions.
Paper 4 demonstrates that Arctic coastal erosion releases vast amounts of matrix-free, easily degradable organic carbon into the marine system, where it reenters the active carbon cycle.
