As corals die due to warming oceans (SN: 2/3/18, p. 16), the overall complexity of the reef also diminishes, leaving a coast potentially more exposed.

However, certain areas in the oceans could be unusually warm and skew the overall long - term average temperature results of some of those prior studies, Shuman says.

The IPCC's overall estimate of global sea level rise, which includes all the other factors that affect sea levels, such as melt from Greenland's ice sheets and the oceans expanding as they warm, is 60 cm by 2100 (with a likely range of 42 to 80 cm).

Scientists believe climate change — the warming of oceans — has allowed some of the almost 2,000 jellyfish species to expand their ranges, appear earlier in the year and increase overall numbers, much as warming has helped ticks, bark beetles and other pests to spread to new latitudes.

Given the total energy content of the oceans, the result could only ever be minimal overall warming of that part of the ocean that exchanges energy with the troposphere.

Terrell Johnson, reporting on a recent NASA publication concluding that deep ocean temperatures have not increased since 2005 (http://www.weather.com/science/environment/news/deep-ocean-hasnt-warmed-nasa-20141007): «While the report's authors say the findings do not question the overall science of climate change, it is the latest in a series of findings that show global warming to have slowed considerably during the 21st century, despite continued rapid growth in human - produced greenhouse gas emissions during the same time.»

Given all the independent lines of evidence pointing to average surface warming over the last few decades (satellite measurements, ocean temperatures, sea - level rise, retreating glaciers, phenological changes, shifts in the ranges of temperature - sensitive species), it is highly implausible that it would lead to more than very minor refinements to the current overall picture.

However, a lot is not: instead it contributes to the overall warming of the deep ocean that has to occur for the climate system to equilibrate.

What this means is that the overall rate of absorption of CO2 by the oceans is a complex function of numerous processes — biological, chemical and physical — whose individual contributions are still a matter of active scientific research (and which are certainly changing as the planet warms).

If in exceeds out and the diffential MUST exist from top to bottom of the atmosphere, then before the hotter air can migrate to the deep ocean, the daily temerature cycling will force the hotter air at the bottom into an overall equlibrium ie hotter air will rise — or more correctly since GHGs have heated the air up more at the bottom, then the sun induced daily warming will add more heat to the top, & less at the bottom to force the equilibrium — ie effectively hot air rising even if not in actuality.

The news service reports, «Scientists believe climate change — the warming of oceans — has allowed some of the almost 2,000 jellyfish species to expand their ranges, appear earlier in the year and increase overall numbers, much as warming has helped ticks, bark beetles, and other pests to spread to new latitudes.»

A main control on atmospheric CO2 appears to be the ocean surface temperature, and remains a possibility that a significant part of the overall increase of atmospheric CO2 since at least 1958 (start of Mauna Loa observations) simply relflects the gradual warming of the oceans as a result of the prolonged period of high solar activity since 1920 (Solanki et al., 2004).

The «warming» of the troposphere as measured by sensible heat is only one very small part of the energy in the overall climate system, and the part with the very lowest thermal inertia and very sensitive to very small changes in ocean to atmosphere sensible and latent heat flux such as we see in the ENSO cycle.

So although warm water is reaching the continental shelves, and creating some melting, the overall effect is to deliver a cold freshwater layer to the top hundred metres or so of the surrounding ocean.

We do know that ocean basins produce this oscillatory behavior — the El Nino / Southern Oscillation, the Arctic Oscillation, the Pacific Decadal Oscialltion, the NAO, the Madden - Julian Oscillation (Indian Ocean), but they seem to have a bit of a random component, their forcing mechanisms are poorly understood, their «phase changes» appear impossible to predict very far in advance, and they must also be sensitive to the overall climate warocean basins produce this oscillatory behavior — the El Nino / Southern Oscillation, the Arctic Oscillation, the Pacific Decadal Oscialltion, the NAO, the Madden - Julian Oscillation (Indian Ocean), but they seem to have a bit of a random component, their forcing mechanisms are poorly understood, their «phase changes» appear impossible to predict very far in advance, and they must also be sensitive to the overall climate warOcean), but they seem to have a bit of a random component, their forcing mechanisms are poorly understood, their «phase changes» appear impossible to predict very far in advance, and they must also be sensitive to the overall climate warming.

They also found that, consistent with my team's research, about 30 % of overall global warming has gone into the deep oceans below 700 meters due to changing wind patterns and ocean currents.

This was the conclusion of a scientific paper I co-authored last year, in which our team found more overall global warming (of the oceans, air, land, and ice combined) over the past 15 years than during the prior 15 years.

While the warming of average global surface temperatures has slowed (though not nearly as much as previously believed), the overall amount of heat accumulated by the global climate has not, with over 90 percent being absorbed by the oceans.

And remember, the satellite data are one small part of a vast amount of data that overwhelmingly show our planet is warming up: retreating glaciers, huge amounts of ice melting at both poles, the «death spiral» of arctic ice every year at the summer minimum over time, earlier annual starts of warm weather and later starts of cold weather, warming oceans, rising sea levels, ocean acidification, more extreme weather, changing weather patterns overall, earlier snow melts, and lower snow cover in the spring...

With a rise in the overall temperature of the ocean, ocean - borne storms such as tropical storms and hurricanes, which get their fierce and destructive energy from the warm waters they pass over, could increase in force.

Steve, is it you belief that events like «ENSO» represent overall changes in heating and cooling of the oceans or represent a change in the movement of warm and cool waters?

It seems clear enough from evidence of the geologic past that before the earth started ringing like a bell every 120K years from glacial to interglacial with the former dominating the other 10:1 in persistence, the Eocene optimum 50 million years ago the earth was ice - free, green from pole to pole, it was about 11F warmer overall, with the most dramatic warming in the highest latitudes (right where you'd want it if you could ask for it), and atmspheric CO2 was several times what it is today, which makes sense in light of much warmer global ocean not able to hold as much CO2.

The «unnatural» warming so far seen is however trended strongly to the alterations to the planetary surface by Humanity over the past 400 years and the rebalance towards greater kinetic induction (in its cumulative effect) is now producing observable alterations not only to the Land Surface median Temperature, but to the Ocean (vie conduction / convection) and a still unconfirmed claim of a small overall rise in Median Atmospheric Temperature, which if «true» would place the Planetary Biosphere on the «Human Population Plot» with regard to «warming».

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).

Elsewhere on this site there is a graph of overall ocean heat content which is building indicating that while the sst is decreasing slightly the overall ocean is warming, It is likely that this overall ocean warming which has nothing to do with changes to the atmospheric temperature because it is the sea surface and not the deep ocean that is in contact with the atmosphere is what is resulting in the overall rise in atmospheric CO2 concentration which is currenly increasing at 2ppmv / year.

Some parts of the ocean are warming less rapidly than we thought, and the overall rate of warming is less than the models projected (modeled, etc..)

Remember that there is a variable lag between the initial solar effect of warming or cooling on the Pacific Ocean and that effect then working through all the other oceanic oscillations so it is difficult to establish the overall balance of the oceanic oscillations at any given time.

I do think, however, that it is significant (short term, not a firm trend) that CO2, as measured at MLO, has been increasing at a smaller rate than in previous years despite the fact that overall anthropogenic CO2 output is not decreasing and, furthermore, that the short term trend of the absolute increase is also down which indicates a greater rate of absorption of CO2 than in previous years — which to me would indicate an ongoing cooling of the oceans as per the theory that a cooling ocean absorbs more CO2 while a warming ocean releases more CO2.

The IPCC's overall estimate of global sea level rise, which includes all the other factors that affect sea levels, such as melt from Greenland's ice sheets and the oceans expanding as they warm, is 60 cm by 2100 (with a likely range of 42 to 80 cm).

The results here reveal a larger picture — that the western tropical Indian Ocean has been warming for more than a century, at a rate faster than any other region of the tropical oceans, and turns out to be the largest contributor to the overall trend in the global mean sea surface temperature (SST)»

Only approximately 15 percent of that decline can be attributed to a warmer mixed - layer, with the remainder being «consistent with an overall decrease in the exchange between surface waters and the ocean interior» (Helm et al., 2011).

The problem is that when Davey correctly pointed out that surface temperatures are only one small piece of overall global warming (about 2 percent), and melting ice and warming oceans must also be considered (over 90 percent of the overall heating of the planet), Neil remained focused exclusively on surface temperatures.

Since the ocean surface warms overall at about only half the rate of the land surface (due to the larger thermal inertia), it is to be expected that the lower troposphere wouldn't warm as fast as the global surface average.

By averaging temperature measurements all round the world, including the surface of the oceans, they have all found essentially the same result — average temperature varied little until the 1920s, and since then there has been an overall warming of about 0.8 °C.

Atmosforests.org It supports the theory that: The sun, the earth, atmosphere, oceans and rainforests, are a complex living organism and the only natural system of the creation, able to adjust and maintain the balance of the atmosphere, of the global warming, oxygen, ozone, general DNA and the overall balance of the planet.

But, he added, human - induced global warming has been raising the overall temperature of the surface ocean, by about one degree Fahrenheit since the 1970s.

Scientists believe climate change — the warming of oceans — has allowed some of the almost 2,000 jellyfish species to expand their ranges, appear earlier in the year and increase overall numbers, much as warming has helped ticks, bark beetles and other pests to spread to new latitudes.

So, if you wish to commit yourself to a net positive feedback to ocean warming resulting in greater overall warming as a result of internal variations in SST, then you are also committed to increased humidity as a net positive feedback to warming due to CO2 forcing.

Presumably if the deep ocean warms significantly, that could eventually reduce the level of surface cooling due to upwelling, since there would be less overall temperature change between the deep and the surface.

Warm ocean temperatures are one of the key factors that strengthen hurricane development when overall conditions are conducive for their formation and growth.

The highly toxic short term engineered cool - downs come at the cost of an even worse overall planetary warming, this includes the Earth's oceans.
