Arctic Permafrost: Methane Emissions and Tipping Points

Integrated satellite and ground sensors map thermokarst formation and methane release, revealing spatially clustered hotspots that can accelerate regional warming.

Management

Data-informed mitigation focuses on wetland restoration and fire management to reduce thaw triggers.

FAQs

Runaway effect? Local feedbacks are strong; global outcomes depend on emissions trajectories.
