Well, many people might associate this to the increase in the movement of particles that occurs along with the increase in temperature, but that might not be enought to move ocean water to different places.
I'd relate it to density. Because, the higher the movement of particles, the lover the density. Which means that if we start cooling and sinking bringing new water to the surface, and if that becomes a cycle, along with water currents, we can create a movement.
↑ In my opinion, that is a really good point, so you should elaborate more on how the water currents will affect the process, and that should be it.
Hope it helped,
