Thus, during an El - Nino, much of the heat content of the Indo - Pacific warm pool moves from being too deep for surface measurements to detect, to being spread out on the surface of the ocean, where surface measurements can detect it.

If more of the heat from global warming is going into the ocean, does that reduce the amount of surface warming (both transiently and long - term) that we should expect from doubling CO2?

Once heated, the ocean surface becomes warmer than the atmosphere above, and because of this heat flows from the warm ocean to the cool atmosphere above.

In today's ocean, warm, salty surface water from the Caribbean, the Gulf of Mexico, and the equatorial Atlantic flows northward in the Gulf Stream.

The first is to emphasize your point that degassing of CO2 from the oceans is not simply a matter of warmer water reducing CO2 solubility, and that important additional factors include changes in wind patterns, reduction in sea ice cover to reveal a larger surface for gas escape, and upwelling of CO2 from depths consequent to the changing climate patterns.

Other factors would include: — albedo shifts (both from ice > water, and from increased biological activity, and from edge melt revealing more land, and from more old dust coming to the surface...); — direct effect of CO2 on ice (the former weakens the latter); — increasing, and increasingly warm, rain fall on ice; — «stuck» weather systems bringing more and more warm tropical air ever further toward the poles; — melting of sea ice shelf increasing mobility of glaciers; — sea water getting under parts of the ice sheets where the base is below sea level; — melt water lubricating the ice sheet base; — changes in ocean currents -LRB-?)

Now, if we want to move further into the future, we have to include the oceans, which are also absorbing heat from the atmosphere — so if we warm the atmosphere, we warm the oceans (as well as the land surface).
