One such feedback loop is the thawing of the permafrost. Some of the permafrost found today was formed thousands of years ago in previous ice ages. Within this ancient layer of frozen ground many organic materials are stored intact, kept from decomposing by the frigid temperature. Entire mammoths - complete with hair and muscle - have been pulled from this arctic carbon storehouse!

Question: As anthropogenic emissions cause temperature to increase, the top layer of permafrost which temporarily thaws in summer is thawed to a greater depth. How would you expect the increased depth of this seasonally defrosted layer to increase GHG emissions?
