Ocean’s heat cycle shows that atmospheric carbon may be headed elsewhere
A recent study in the journal Nature Geoscience examined the global carbon cycle and suggests that existing studies may have misgauged how carbon is distributed around the world, particularly between the northern and southern hemispheres. The results could change projections of how, when and where the currently massive levels of atmospheric carbon will result in environmental changes such as ocean acidification.
By re-examining ocean circulations and considering the carbon-moving power of rivers, the study’s authors suggest that as much as 40 percent of the world’s atmospheric carbon absorbed by land needs to be reallocated from existing estimates. In particular, the Southern Ocean encircling Antarctica and forests in the northern hemisphere — while still substantial absorbers or “sinks†of carbon — may not take up as much as scientists have figured.
