Permafrost 41
Set 5 www.climatefresk.org 41 Permafrost refers to permanently frozen ground. We see that it begins to thaw, releasing methane and CO 2 into the atmosphere. These gases come from previously frozen organic matter which starts to decompose. Melting permafrost creates an amplifying feedback loop, just like forest fires and albedo changes due to melting sea ice.
