If the atmospheric CO2 content is increasing due to anthropogenic activities causing possible climate change then has the world oceans reached their limits as CO2 sink?

Over the geological past the world oceans have acted as veritable sinks of atmospheric CO2 that caused the formation of various carbonate deposits. This also had modulated the past climates. The relative efficacy and global-scale importance of oceans and forests in natural sequestration of CO2 is not known. Past ocean records however indicate that ocean waters are capable of absorbing large quantities of CO2. In this situation an answer is required for the question why the oceans are incapable of responding as CO2 sink to sequester the increasing volume of CO2 emission. We need to study physico-chemical aspects of ocean waters and ocean-atmosphere interface characters to get an answer.

There are still lots of uncertainties about the quality of human life and other species in view of the rapidly changing land-surface and its consequent interactions with the lower atmosphere. Gathering more information about this will help to redirect investments and draw up appropriate response to ensure human survival.
