However, there is also a huge reservoir of cold water in the deep oceans.

Setting aside the effects of the deep ocean, etc, — ie just using a single unified reservoir's heat capacity — and using only fast feedbacks (I didn't introduce any slow feedbacks anywhere in this particular series of comments), the expectation based on physics is that each delayed response T curve (each of which must correspond to a different value of heat capacity, for the same ECS) must have a maximum or minimum when it intersects the instantaneous response curve (my Teq value)-- maximum if it was below Teq before, minimum if it was above — because it is always going toward Teq.

The solutions they considered were: setting up a rural water supply program providing poor communities in Africa with deep boreholes and public hand pumps; developing campaigns that raise awareness of disease transmission, health costs, and the social benefits of sanitation; ensuring affected communities have access to technology to remove contaminants in raw water supplies; building reservoirs in some parts of Africa, such as the sparsely inhabited Blue Nile gorge in Ethiopia.

IF cool deep sea water were mixed relentlessly with surface water by some engineering method --(e.g. lots of wave operated pumps and 800m pipes) could that enouromous cool reservoir of water a) mitigate the thermal expansion of the oceans because of the differential in thermal expansion of cold and warm water, and b) cool the atmosphere enough to reduce the other wise expected effects of global warming?
