The global carbon cycle comprises two parts: firstly, the human derived (anthropogenic) flux of about 8 PgCy-1of which the oceans take up about 2 PgCy-1, and the Southern Ocean contributes about 1PgCy-1.  Secondly, a very much larger but up to now balanced ocean – atmosphere exchange of natural CO2 of approximately 90GtCy-1. The steady-state magnitudesRead More..
