Card #41: Permafrost

Causes		Consequences
Temperature Rise ou Energy Budget		Other GHGs

Permafrost is permanently frozen ground.
Permafrost thawing leads to the decomposition of organic matter previously frozen underground, a phenomenon that releases methane and CO₂ into the atmosphere.
Beyond +2°C, it is almost certain this phenomenon will accelerate and make the climate spiral out of control.
