Despite slower temperature shifts in ocean waters, ocean life from plankton to fish have begun moving in response to global warming

Antarctica was also more sensitive to global carbon dioxide levels, Cuffey said, which increased as the global temperature increased because of changing ocean currents that caused upwelling of carbon - dioxide - rich waters from the depths of the ocean.

However, in the 2013 Fifth Assessment Report (AR5), the IPCC concluded that «Modelling indicates that SRM methods, if realizable, have the potential to substantially offset a global temperature rise, but they would also modify the global water cycle, and would not reduce ocean acidification.»

By next year, the Argo project will have installed 3,000 floating sensors across all the oceans, offering a daily snapshot of global patterns of water temperature and salinity — crucial for predicting the nature and pace of climate change.

Our results indicate that for a large ‐ enough olivine deployment of small ‐ enough grain sizes (10 µm), atmospheric CO2 could be reduced by more than 800 GtC by the year 2100.

There is a clear impact on global temperature, too, though the mechanisms are complex: heat released from the oceans; increases in water vapor, which enhance the greenhouse effect, and redistributions of clouds.

In addition, since the global surface temperature records are a measure that responds to albedo changes (volcanic aerosols, cloud cover, land use, snow and ice cover) solar output, and differences in partition of various forcings into the oceans / atmosphere / land / cryosphere, teasing out just the effect of CO2 + water vapor over the short term is difficult to impossible.

[1] CO2 absorbs IR, is the main GHG, human emissions are increasing its concentration in the atmosphere, raising temperatures globally; the second GHG, water vapor, exists in equilibrium with water / ice, would precipitate out if not for the CO2, so acts as a feedback; since the oceans cover so much of the planet, water is a large positive feedback; melting snow and ice as the atmosphere warms decreases albedo, another positive feedback, biased toward the poles, which gives larger polar warming than the global average; decreasing the temperature gradient from the equator to the poles is reducing the driving forces for the jetstream; the jetstream's meanders are increasing in amplitude and slowing, just like the lower Missippi River where its driving gradient decreases; the larger slower meanders increase the amplitude and duration of blocking highs, increasing drought and extreme temperatures — and 30,000 + Europeans and 5,000 plus Russians die, and the US corn crop, Russian wheat crop, and Aussie wildland fire protection fails — or extreme rainfall floods the US, France, Pakistan, Thailand (driving up prices for disk drives — hows that for unexpected adverse impacts from AGW?)

Long waves (infrared) light from the sun, GHGs, clouds, are trapped at the surface of the oceans, directly leading to increased «skin» temperature, more water vapor (a very effective GHG), faster convection (with more loss of heat to space in the tropics),... How each of them converts to real regional / global temperature increases / decreases is another point of discussion...

Human water vapour emissions are irrelevant, as water vapour is in dynamic equilibrium with ocean water, an equilibrium controlled by global mean temperature, i.e., other greenhouse gases etc..

These record temperatures have been assisted by a very strong El Niño event, which brought warm water to the ocean surface, temporarily warming global surface temperatures.

If scientists need to rely on bucket samples of water to prove the historic global temperature of our oceans, perhaps it is time to recognise that there are some aspects of our climate data that are not worth relying on.

Global temperatures tend to decrease in the wake of La Niña, which occurs when upwelling cold water off the coast of Peru spreads westward in the equatorial Pacific Ocean.

Water takes longer to heat up and cool down than does the air or land, so ocean warming is considered to be a better indicator of global warming than measurements of global atmospheric temperatures at the Earth's surface.

From the article: A new study released Monday found that warming temperatures in Pacific Ocean waters off the coast of North America over the past century closely followed natural changes in the wind, not increases in greenhouse gases related to global warming.

Use of this type of modeling allows for better understanding of the effects of OTEC deployment in global phenomena (changes in water temperature and its effect on atmosphere - ocean interaction or global warming, to name some).

Having a high humidity allows ocean to get highest surface temperature, but less humidity would allow ocean store energy in form of water vapor [which allow more energy to stored in terms energy of earth's global budget].

So how our environmental future plays out now is that as the poles melt, the ocean heats, and water surface area increases, atmospheric H2O skyrockets and some time later as the temperature passes through 4 deg C heading for 5 deg C global temperature rise, the ocean currents start to stall.

Global surface temperatures in the last few years have received a bump in recent years because of a large El Niñ0 event, which brought warm water up from the depths of the Pacific ocean and released the energy into the atmosphere.

This is so because climate change has already caused changes to the global climate system such as raising ocean temperatures and increasing the amount of water in the atmosphere.

In addition to rising temperatures, the report discussed a variety of «other possible effects of an increase in atmospheric carbon dioxide», including melting of the Antarctic ice cap, rise of sea level, warming of sea water, increased acidity of fresh waters (which also applies to the danger of ocean acidification, global warming's evil twin), and an increase in plant photosynthesis.

Ragnaar, the water vapor is in equilibrium with the ocean temperature that has risen less than the global temperature, so its response relative to the global temperature may be less than 7 % per degree, while it is 7 % per degree for the ocean.

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).

Dead zones — massive stratified columns of oxygen - deprived water — could become the new normal in oceans around the world as global temperatures continue to rise.

Reports show the ocean's unique ecosystems are adapting to fluctuation in water temperatures likely caused by global warming, but increasing acidic levels may prove fatal for the world's coral reefs.

As global temperature increases, thermal expansion of ocean water and melting of glaciers occur.

A slight change of ocean temperature (after a delay caused by the high specific heat of water, the annual mixing of thermocline waters with deeper waters in storms) ensures that rising CO2 reduces infrared absorbing H2O vapour while slightly increasing cloud cover (thus Earth's albedo), as evidenced by the fact that the NOAA data from 1948 - 2008 shows a fall in global humidity (not the positive feedback rise presumed by NASA's models!)

The Pacific, and what happens in local waters in its east and west is the focus of ENSO studies and these phenomena are commonly compared to the march in global temperatures but its what happens in the global ocean that is really important for temperature gain and loss on a global basis.

We know that as the global average temperature rises, more water evaporates from the oceans.

The potential spoiler is the cyclical El Nino event: a band of unusually warm ocean water that periodically forms along the equatorial Pacific Ocean and drives up global temperatocean water that periodically forms along the equatorial Pacific Ocean and drives up global temperatOcean and drives up global temperatures.

It is not «conduction» but exchange of radiation; if you keep your hands parallel at a distance of some cm the right hand does not (radiatively) «warm» the left hand or vice versa albeit at 33 °C skin temperature they exchange some hundreds of W / m ² (about 500 W / m ²) The solar radiation reaching the surface (for 71 % of the surface, the oceans) is lost by evaporation (or evapotranspiration of the vegetation), plus some convection (20 W / ²) and some radiation reaching the cosmos directly through the window 8µm to 12 µm (about 20 W / m ² «global» average); only the radiative heat flow surface to air (absorbed by the air) is negligible (plus or minus); the non radiative (latent heat, sensible heat) are transferred for surface to air and compensate for a part of the heat lost to the cosmos by the upper layer of the water vapour displayed on figure 6 - C.

Global surface temperatures were the 8th or 9th highest recorded, partly because the first two months were cool - ish thanks to a La Nina in the Pacific, where cooler waters sit on the top of the ocean and suck up heat from the atmosphere.

Figure 15 - A has shown the global pacing by the El Niños (and their tele - connections) of the temperature changes of the lower troposphere as function of both time and latitude; this pacing may be due to the coming to the surface, at high latitudes, of warm water from the Pacific warm pool, as they move to higher latitudes on the western rim of the oceans after an El Niño.

ANSWER: There is not «A» temperature of the oceans but a constantly changing distribution of temperatures and of partial pressures of the gases; figure 17 - D from the Publications Office of the European Union gives a global view with some time averaging: it is anywhere between 280 µatm and 430 µatm in the water!

Global climate change has contributed to the higher sea surface and sub-surface ocean temperatures, a warmer and moister atmosphere above the ocean, higher water levels around the globe, and perhaps more precipitation in storms.»
