hurricanes happen, which accelerate the transition of living biomass of trees into
dead organic matter. If on the USA territory, 20 TgC are removed from the forests
every year, then 10
-
15 % of this is the result of one hurricane (McNulty 2002).
Hence, the hurricanes accelerate the return of carbon to the atmosphere, and their
global inventory is needed to more accurately estimate numerous components of the
global carbon cycle.
