Question

Carbon dioxide diffuses into the ocean carbon cycle via the air-sea surface exchange. Molecules of CO2 enter the ocean by diffusing into the surface waters and dissolving. The amount of CO2 that diffuses and dissolves in the surface water depends on several variables. Scientists have noted that sea more CO2 diffuses and dissolves in colder sea surface water and less CO2 diffuses and dissolves in warmer water. Let's assume the predictions of scientists predicting a warming climate are true. Can you predict the outcome if average ocean temperatures increase as well? Include the effects on appropriate components of the biosphere as well as the hydrosphere.

Answer 1

Warmer oceans would mean less dissolved CO2 as well as other gases such as oxygen in the global ocean. Lower CO2 would result in a decrease in photosynthesis of autotrophs living in the oceans.
