41 - Permafrost

Permafrost 41
Set 5 www.climatefresk.org 41 Permafrost is permanently frozen ground. It is starting to thaw, releasing into the atmosphere previously locked in methane and CO 2 from decomposed biomass. This creates a positive feedback loop, just like forest fires and albedo changes due to melting sea ice.

Energy Budget

If we take the idea of energy conservation all the way, we can link the energy budget to the thawing of permafrost.

Additional Greenhouse Effect

Permafrost

The permafrost card can be linked either to Other GHGs or to Additional Greenhouse Effect. The Other GHGs card is about GHGs emitted by human activities, while the methane in permafrost is not of human origin.
