I also found an interesting post and response that discussed fresh water possibly being behind sea level not behaving in
a way ocean cooling would indicate.

But sulphate pollution stays close to its source, and climatologists have been puzzled to find that the northern
oceans, a long

cooled in recent decades.
Climate models do not predict an even warming of the whole planet: changes in wind patterns and
ocean currents can change the
way heat is distributed, leading to some parts warming much faster than average, while a few may
cool, at least at first.
The same lack of waterproofing leads chicks to die from heat stroke on hot days, when a dip in the

I particularly enjoyed the slides that, when combined (1) provided an overview of hotter and
cooler CO2 molecules as it relates to how they are seen from outer space and from profile — because this will make it easier for me to explain this process to others; (2) walked through the volcanic and solar activity vs assigning importance to CO2 changes — because this another
way to help make it clearer, too, but in another
way; (3) discussed CO2 induced warming and
ocean rise vs different choices we might make — because this helps point out why every day's delay matters; and (4) showed Figure 1 from William Nordhaus» «Strategies for Control of Carbon Dioxide» and then super-imposed upon that the global mean temperature in colors showing pre-paper and post-paper periods — because this helps to show just how far back it was possible to make reasoned projections without the aid of a more nuanced and modern understanding.
In terms of the so - called «pause», it becomes more and more clear that the current
cool phase of the PDO is largely responsible for this «pause», but looking at the continued rise in
ocean heat content, and the nice job Cowtan &
Way have done interpolated Arctic temperatures, we see that the «pause», may have reflected a slowdown in the rise of tropospheric temperatures, but the energy imbalance of the climate system continues quite strongly.
From sheer thermal inertia of the
oceans, but also because if you close down all coal power stations etc., aerosol pollution in the atmosphere, which has a sizeable

way down, while CO2 stays high.
Either a big chunk of ice has been melting extraordinarily fast — which would
cool the surrounding air — or somehow
ocean currents would have changed in a
way that favoured more rapid warming of deep water.
I also suspect that a good portion of the additional warming shown in the hybrid version of the Cowtan and
Way (2013) data (versus their Krig data) comes from the Southern
Ocean surrounding Antarctica, where sea surface temperatures are
cooling and lower troposphere temperatures are warming.
Only in certain regions, notably in the Antarctic and northwest Atlantic
Oceans, does a combination of evaporation (which increases the water's salt content) and wintertime
cooling make surface water dense enough to sink all the
way down.
All the sea surface water, warmed by the tropical sun, is blown to the west of the Pacific and, to compensate part of the imbalance,
cooler deep
ocean waters well up on the western shores of Latin America (and spread all the
way up to the Solomon Islands).
The liquid condensed at the bottom evaporates creating local
cooling and rises; the
way ocean water and all water does from the surface as an enormous pool of evaporative phase change refrigerant for the surface (and the atmospheric bath of nitrogen / oxygen).
Now there is another on the
way, and we wait to see whether it will do the same, or whether the Arctic
Ocean has
cooled enough to protect the remaining ice somewhat.
Tomorrow we'll pay attention to that very interesting new study about clouds — a bombshell we think — but today we have another one that should serve as a foundation to scientific thinking about climate forcing, namely the suggestion that «not all climate forcers are equal» — equal in the
way they act as a
cooling or warming force, considering important factors like time scale and the geographical characteristics of a planet with a 3D atmosphere and a northern hemisphere with land masses and a southern hemisphere with just mainly a lot of
oceans.
To point out just a couple of things: —
oceans warming slower (or
cooling slower) than lands on long - time trends is absolutely normal, because water is more difficult both to warm or to
cool (I mean, we require both a bigger heat flow and more time); at the contrary, I see as a non-sense theory (made by some serrist, but don't know who) that
oceans are storing up heat, and that suddenly they will release such heat as a positive feedback: or the water warms than no heat can be considered ad «stored» (we have no phase change inside
oceans, so no latent heat) or
oceans begin to release heat but in the same time they have to
cool (because they are losing heat); so, I don't feel strange that in last years land temperatures for some series (NCDC and GISS) can be heating up while
oceans are slightly
cooling, but I feel strange that they are heating up so much to reverse global trend from slightly negative / stable to slightly positive; but, in the end, all this is not an evidence that lands» warming is led by UHI (but, this effect, I would not exclude it from having a small part in temperature trends for some regional area, but just small); both because, as writtend, it is normal to have waters warming slower than lands, and because lands» temperatures are often measured in a not so precise
way (despite they continue to give us a global uncertainity in TT values which is barely the instrumental's one)-- but, to point out, HadCRU and MSU of last years (I mean always 2002 - 2006) follow much better waters» temperatures trend; — metropolis and larger cities temperature trends actually show an increase in UHI effect, but I think the sites are few, and the covered area is very small worldwide, so the global effect is very poor (but it still can be sensible for regional effects); but I would not run out a small warming trend for airport measurements due mainly to three things: increasing jet planes traffic, enlarging airports (then more buildings and more asphalt — if you follow motor sports, or simply live in a town / city, you will know how easy they get very warmer than air during day, and how much it can slow night - time
cooling) and overall having airports nearer to cities (if not becoming an area inside the city after some decade of hurban growth, e.g. Milan - Linate); — I found no point about UHI in towns and villages; you will tell me they are not large cities; but, in comparison with 20-40-60 years ago when they were «countryside», many small towns and villages have become part of larger hurban areas (at least in Europe and Asia) so examining just larger cities would not be enough in my opinion to get a full view of UHI effect (still remembering that it has a small global effect: we can say many matters are due to UHI instead of GW, maybe even that a small part of measured GW is due to UHI, and that GW measurements are not so precise to make us able to make good analisyses and predictions, but not that GW is due to UHI).
The best
way to envision the relation between ENSO and precipitation over East Africa is to regard the Indian
Ocean as a mirror of the Pacific
Ocean sea surface temperature anomalies [much like the Western Hemisphere Warm Pool creates such a SST mirror with the Atlantic
Ocean too]: during a La Niña episode, waters in the eastern Pacific are relatively
cool as strong trade winds blow the tropically Sun - warmed waters far towards the west.
Losing the perennial Arctic sea ice is speeding up the melting and partial disintegration of the great Greenland Ice Sheet, and is also having an effect in Antarctica, partly through disruption of the «great
ocean conveyor» which sends Arctic -
cooled water all the
way to the Antarctic.
Jim, my thoughts are that the deepening of the Antarctic
ocean allowing a circumnavigation of waters, the closure of the Panama opening, the
cool waters going up Atlantic
way increasing productivity and blooms of krill evidenced by whales to get to their massive size in the last two million years.
Heat does transfer from the warmer upper part of the
ocean to the deeper
cooler part, not the other
way around as you claim, but it's balanced by flows of cold water descending into the deep
ocean near the poles.
Finally, each step along the
way that resulted in
cooler oceans would have caused an eventual drop in CO2 levels.
Others accept (correctly) that that is unlikely due to the thermal inertia of our
oceans and their
cooling effect on the air so they propose an «
ocean skin'theory whereby warming of the topmost molecules on the
ocean surface from extra downwelling infra red radiation from extra human CO2 in the air is supposed to reduce the natural energy flow from sea to air so that the
oceans get warmer and then heat the air and kill us off that
way.
To my understanding this is not a big effect, and it could cut both
ways - warm rain can fall on a
cool ocean as well.
Dr. Mojib Latif, a prize - winning climate and
ocean scientist from the Leibniz Institute of Marine Sciences at the University of Kiel, wrote a paper last year positing that cyclical shifts in the
oceans were aligning in a
way that could keep the next decade or so relatively
cool, even as the heat - trapping gases linked to global warming continue to increase.
The powerful Antarctic Circumpolar Current began to sweep all the
way around the continent, effectively isolating Antarctica from most of the warmth from the global
oceans and provoking large - scale
cooling.
But I do not see any simple
way to verify the no - feedback sensitivity; if you include evaporative
cooling from the
ocean surface (for example), then you immediately get into the feed - back issues of water vapor and cloud cover.
