The oceans buffer global warming in two ways: on the one hand, water absorbs a large part of the additional energy introduced into the climate system; on the other hand, some of the CO2 from the atmosphere is dissolved in the water and bound there. As the water temperature rises, however, this buffering effect decreases, so that CO2 is released again. This further intensifies the greenhouse effect and thus also causes the water temperature to rise further - an example of a positive (self-reinforcing) feedback process.
