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.

El Niño — a warming of tropical Pacific Ocean waters that changes weather patterns across the globe — causes forests to dry out as rainfall patterns shift, and the occasional unusually strong «super» El Niños, like the current one, have a bigger effect on CO2 levels in the atmosphere.

I'm a fish geneticist so I won't bother commenting on «paleo - ocean current - ology», but it seems to me that glaciation would result in a reduction of fresh water inputs to the North Atlantic (during the ice age) and would therefore be quite different from the mechanism in question (which is related to early phases of global warming).

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-?)

There is some discussion over what effect greenhouse warming will have on ocean currents, particularly the Gulf Stream, which warms Europe with tropical water.

In order to properly understand, what is going on in the Arctic ocean, we first must understand the oceanic oscillation and the currents in this vast ocean, it is interesting to note, Sweden is recalling its ice breaker from the USA Antarctic survey, and there is concern in the sea of Okhotsk — where, for the last couple of years breaking the winter sea ice has been a major problem, colder here, relatively «warmer» there etc..

And that estimate was based on the idea that ocean warming and acidification will stay at current rates.

Warm currents transport heat from lower latitudes poleward and tend to occur on the western sides of oceans.

It's very clear (thanks to Steve M, Willis etc) that there are issues with both but given the current hyped claim by the «warmers» that the past effects of man - caused global warming have largely been masked by the warming of the oceans and that unless we reduce CO2 emissions now that we won't be able to mitigate future global warming when this «stored heat» eventually comes back out of the oceans and leads to catastrophic effects, I'm very interested in getting to the punchline of this debate on SSTs.

But if you accept that the greenhouse effect is real, and that CO2 is a GHG, and that CO2 has increased (along with other GHGs), you have to accept the merit of my point: that solar, volcanoes, ocean currents and other natural variations do their thing, they vary, but GHGs exert a steady, constant upward forcing on temperature, which upward forcing is only offset by increased heat losses to space from a warmer planet.

So while admitting, there probably is a very modest amount of AGW in the current warming cycle, it could just as easily have been caused by: i) the effects of the huge increase in global irrigation, ii) tiny changes in the sun's radiation, and / or iii) the knock on effects of changes in the intensity and direction of ocean currents.

For example, reductions in seasonal sea ice cover and higher surface temperatures may open up new habitat in polar regions for some important fish species, such as cod, herring, and pollock.128 However, continued presence of cold bottom - water temperatures on the Alaskan continental shelf could limit northward migration into the northern Bering Sea and Chukchi Sea off northwestern Alaska.129, 130 In addition, warming may cause reductions in the abundance of some species, such as pollock, in their current ranges in the Bering Sea131and reduce the health of juvenile sockeye salmon, potentially resulting in decreased overwinter survival.132 If ocean warming continues, it is unlikely that current fishing pressure on pollock can be sustained.133 Higher temperatures are also likely to increase the frequency of early Chinook salmon migrations, making management of the fishery by multiple user groups more challenging.134

A section on current conditions shows the last two months are characterized by relatively normal atmospheric conditions over the Arctic Ocean, but warmer than normal conditions over the subpolar seas and land around the Arctic Ocean.

Two items: the first, the layered Ocean currents, fresh water on top, then the warmer but saltier layer and finally the deep bottom layer.

Over the past fifty million years, earth cooled because land moved, ocean currents changed, more and more warm water was circulated in higher Latitudes and Polar Oceans to melt more and more sea ice to support more and more snowfall to promote more and more ice on land.

Other feared effects — such as the sudden release of large volumes of methane from thawing Arctic tundra or the disruption of the Atlantic Ocean currents that carry warm water into the northern latitudes — were given a low chance of occurring on a rapid scale.

Adding heat to the ocean, in contrast, slows down the overturning circulation because ocean currents depend on temperature gradients — moving from warmer locations to cooler locations — that weaken under global warming as cooler waters heat up.

Compiled recent findings on the interconnection of warming trends, and possible implications for ocean currents and what it could mean.

Continents drifted and changed ocean currents and routed more and more warm tropical water into Polar Regions and that thawed more and more of the Polar Oceans to promote more and more snowfall and that did support more and more ice on land.

Ocean currents cool or warm nearby coasts, depending on their temperature.
