To top it off, the ocean is heated from above, which means that we would have to wait the natural cycling of the ocean`s water in order to have it all heated up. This cycle takes several thousand years.
Your entire post makes sense to me, except for this last point (above). I was unaware that there are oceanic cycles that substantially disturb the global water column and occur with periods of several thousand years. Probably the effects of such dynamics are quite variable on a global scale. I was under the impression that deep-trench water, for example, is so firmly locked inplace as to be regarded as "fossilized water." Once I took part in a study for USDOE to determine if high-level nuclear wastes could be disposed of in these trenches. Dixie Lee Ray, the energy secretary back then, was promoting deep-sea burial of HLW. The study concluded, affirmatively for her, that once those HLW settled into a trench they would be there for a very long time, even while decay-heating the ambient water. (This is NOT my preferred method of HLW disposal.) So I am curious about these verticle natural cycles. Do you have a reference to recommend?
