VAST OCEANIC CARBON SINKS. “Oceans are at present CO2 sinks, and represent the largest active carbon sink on Earth, absorbing more than a quarter of the carbon dioxide that humans put into the air. On longer timescales they may be both sources and sinks – during ice ages CO2 levels decrease to ~180 ppmv, and much of this is believed to be stored in the oceans. As ice ages end, CO2 is released from the oceans and CO2 levels during previous interglacials have been around ~280 ppmv.””
