So the report notes that the current «pause» in new global average temperature records since 1998 — a year that saw the second strongest El Nino on record and shattered warming records — does not reflect the long - term trend and may be explained by the oceans absorbing the majority of the extra heat trapped by greenhouse gases as well as the cooling contributions of volcanic eruptions.

Oceanographers may have solved one of the biggest sea mysteries in years: why the upper ocean didn't warm between 2003 and 2010, even as heat - trapping greenhouse gases accumulated in the air above.

While the planet's surface didn't warm as fast, vast amounts of heat energy continued to accumulate in the oceans and with the switch in the PDO, some of this energy could now spill back into the atmosphere.

Because existing phenomena — such as thermal expansion of water from warming — do not fully explain the corrected sea - level - rise number of 3.3 millimeters, stored heat in the deep ocean may be making a significant contribution, Cazenave said.

This warm air layer gets its heat reflected downwards during cloudy periods, especially during long night extensive cloudy periods, as a result, Arctic ocean ice doesn't thicken so much during darkness and leaves it up to summer sunlight (if there is some) to finish off what is left of it.

Regional trends are notoriously problematic for models, and seems more likely to me that the underprediction of European warming has to do with either the modeled ocean temperature pattern, the modelled atmospheric response to this pattern, or some problem related to the local hydrological cycle and boundary layer moisture dynamics.

He said he does think, however, that there will a broader shift to warmer ocean conditions that will last for several years and that means that global temperatures will hover around the level they have recently reached before moving upward again, like stairs on a staircase.

Gentlepeople, well done on nipping any controversy in the bud — as usual; though I'm left wondering if the warming trend isn't related to a subject that i'd like to see Real Climate Address more often; The possible shut - down of The North Atlantic Conveyor — as extreme warming of the Southern Oceans, along with the plunging of Europe into a new Ice Age would be the result of this, as I'm sure you all know.

Observations of upper ocean heat show some short term cooling but measurements to greater depths (down to 2000 metres) show a steady warming trend: However, the ocean cooling myth does seem to be widespread so I'll shortly update this page to clarify the issue.

Beachgoers may love ocean waters that are growing balmier in a warming world, but corals, and subsequently the ecosystems they support, do not.

I'd love to know what they did take into account in attempting to model that period — must include astronomical location, sun's behavior, best estimates about a lot of different conditions — where the continents were, what the ocean circulation was doing, whether there had been a recent geological period that laid down a lot of methane hydrates available to be tipped by Pliocene warming into bubbling out rapidly.

The former is likely to overestimate the true global SAT trend (since the oceans do not warm as fast as the land), while the latter may underestimate the true trend, since the SAT over the ocean is predicted to rise at a slightly higher rate than the SST.

Do these ocean findings finally lay to rest any arguments against anthropogenic global warming, according to news coverage claims?

How does a more acid ocean interact with things like warmer seas, or human encroachment such as overfishing or land - based run - off?

The former is likely to overestimate the true global surface air temperature trend (since the oceans do not warm as fast as the land), while the latter may underestimate the true trend, since the air temperature over the ocean is predicted to rise at a slightly higher rate than the ocean temperature.

This analysis by Sedláček & Knutti (2012) does not attempt to connect modelled and observed ocean warming patterns with human activity, but does demonstrate that natural variability is incompatible with the warming in the 20th century simulations, and with historical observations.

As it does so, it oxidises to CO2, dissolving in seawater or reaching the atmosphere as CO2 which causes far slower warming, but can nevertheless contribute to ocean acidification.

There's also plenty they don't know yet — how global warming might affect tornadoes, for example, or how quickly the massive ice caps on Greenland and Antarctica could slide into the oceans.

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?

You've got the radiative physics, the measurements of ocean temperature and land temperature, the changes in ocean heat content (Hint — upwards, whereas if if was just a matter of circulation moving heat around you might expect something more simple) and of course observed predictions such as stratospheric cooling which you don't get when warming occurs from oceanic circulation.

So although greenhouse gases, such as carbon dioxide, don't directly warm the oceans by channeling heat down into the oceans, they still do indeed heat the oceans, and are likely to do so for a very long time.
