Not exact matches

Phenomena such as El Niño or La Niña, which warm or cool the tropical Pacific Ocean, can contribute to short - term variations in global average temperature.

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.

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.

It is in this ever - present mechanism that oceans are able to undergo long - term warming (or cooling).

Because of their effect on lowering the temperature gradient of the cool skin layer, increased levels of greenhouse gases lead to more heat being stored in the oceans over the long - term.

The main point is that just as surface temperatures has experienced periods of short term cooling during long term global warming, similarly the ocean shows short term variability during a long term warming trend.

Given how much yelling takes place on the Internet, talk radio, and elsewhere over short - term cool and hot spells in relation to global warming, I wanted to find out whether anyone had generated a decent decades - long graph of global temperature trends accounting for, and erasing, the short - term up - and - down flickers from the cyclical shift in the tropical Pacific Ocean known as the El Niño — Southern Oscillation, or ENSO, cycle.

In general, the regions of expanding warming upwelling water in the Indian Ocean, North Pacific, or wherever they are, must create slight bulges in the surface, and the regions of shrinking, cooling, sinking water in the Arctic must create slight depressions in the sea surface (again, I mean in a very low pass sense — obviously storms, tides, etc, create all kinds of short - terms signals obscuring this).

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.

This may lead to long term heating and warming cycles in the oceans that are the result of upwheling of cool water from deep within the oceans.

The real problem here is that this AMO explanation was picked up and broadcast by the press in a very uncritical manner, usually in these terms: «Surface waters of the Atlantic ocean warm up then cool down in long, subtle cycles.

It's important to note that a substantial short - term influence on the globe's average temperature, the cycle of El Niño warmth and La Niña cooling in the tropical Pacific Ocean, was in the warm phase until May but a La Niña cooling is forecast later this year, according to the Climate Prediction Center of the National Oceanic and Atmospheric Administration.

* The long - term cooling is related to the situation with the continents — not much subduction of carbonate - rich ocean crustnow.

This cooling is the result of natural long - term swings in ocean surface temperatures, particularly swings in the Interdecadal Pacific Oscillation or mega-El Niño - Southern Oscillation, which has lately been in a mega-La Niña or cool phase.

But as cogently interpreted by the physicist and climate expert Dr. Joseph Romm of the liberal Center for American Progress, «Latif has NOT predicted a cooling trend — or a «decades - long deep freeze» — but rather a short - time span where human - caused warming might be partly offset by ocean cycles, staying at current record levels, but then followed by «accelerated» warming where you catch up to the long - term human - caused trend.

Nice misconception you have going there but the real argument is that CO2 can lower the temperature gradient of the cool skin layer, which slows the heat loss to the atmosphere and increased levels of greenhouse gases lead to more heat being stored in the oceans over the long - term.

Yes, and I suppose when they do they will understand you can't ignore a troposphere that isn't warming at the appropriate rate to the surface; you can't ignore a stratosphere that isn't cooling at the appropriate rate per decade; you can't ignore an ocean that isn't warming despite an assumed large energy imbalance; you can't ignore that if you declare a long lag time or a large long term climate sensitivity then previous forcings are subject to the same principles; and you can't ignore that the rate of warming was no different this last time then the time before it and the time before that.

In nature terms, when the temperatures are cooler, the ocean water is able to hold much more CO2.

The cooling of the stratosphere, and reduction of Arctic Sea ice over the long - term are two other very strong indicators that the increased greenhouse gases are impacting the rate of heat flow from ocean to space.

Phenomena such as El Niño and La Niña — which warm and cool the tropical Pacific Ocean and cause corresponding variations in global wind and weather patterns — contribute to short - term variations in global temperatures.

I think warmer oceans is far more significant in term of some kind of buffer against cooling.

even if there were a period of predominantly positive PDO over the long - term, the oceans would cool as a consequence of the transfer of heat to the overlying air.

It is an oscillation which simply moves heat from oceans to air and vice-versa, so even if there were a period of predominantly positive PDO over the long - term, the oceans would cool as a consequence of the transfer of heat to the overlying air.

Over the past decade, aerosol emissions (which cause cooling by blocking sunlight) have risen, solar activity has been low, there has been a preponderance of La Niña events (which also cause short - term surface cooling), and heat has accumulated in the deep oceans.

In terms of average going from say 80 to 30 C - and in terms getting everything back to normal - depends how long it takes to cool oceans - a relatively very slow process.

Likewise, the term «global warming» is somewhat problematic as well since the planet isn't warming uniformly — a few places have a short - lived cooling trends — and the word «warming» sounds downright cozy on a cold day, when, in fact, substantially heating of the atmosphere and ocean is happening.)

Regardless of near term outcomes — it is odds on for a cooler sun and more upwelling in the Pacific Ocean this century — providing a cooling influence on the oceans and atmosphere and the inevitable regional variability in rainfall.

Figure 1: Short - term cooling trends from Jan»70 to Nov» 77, Nov»77 to Nov» 86, Sep»87 to Nov» 96, Mar»97 to Oct» 02, and Oct»02 to Dec»11 (blue) vs. the 42 - year warming trend (Jan»70 to Dec» 11; red) using NOAA NCDC land - ocean data.

This global tidal «standing wave» leads to a long term disspation of tidal power of ~ 1 terra Watt which is sufficent to provide about 1/2 of the total power needed to drive the up welling of cool water from the deep oceans.

Volcanic eruptions and El Niño events are identified as sharp cooling events punctuating a long - term ocean warming trend, while heating continues during the recent upper - ocean - warming hiatus, but the heat is absorbed in the deeper ocean.

Dessler finds that the short - term changes in surface temperature are related to exchanges of heat to and from the ocean - which tallies well with what we know about El Niño and La Niña, and their atmospheric warming / cooling cycles.

Kevin C's excellent trend tool shows us what the new data mean for the surface temperature trend since 1970: it's about +0.17 C per decade, but there's a range in that because short term wiggles are caused by things like the El Nino - La Nina cycle in the Pacific which warm or cool the atmosphere by storing or releasing heat from the oceans.

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.

Preliminary comparison of solar results with observations indicates that, if the solar influence exists, it is not being manifested in terms of simple cooling; changes in the ocean - atmosphere system may be significantly modifying the response.

The important metric for ocean warming and cooling is net TOA flux — in which in the medium term cloud variability is overwhelmingly the significant factor.

In terms of upward energy flow the cooler interacting layer pulls energy upward exactly as much as the warmer skin slows it down for a zero net effect on the upward rate of flow from the ocean.

Yet the skin layer does show warming and the sub skin is cooler than the ocean bulk Observations rule and as we have seen already the science on these issues is vague and inconclusive so I wouldn't use the term «impossible».

Surface temperatures can show short - term cooling when heat is exchanged between the atmosphere and the ocean, which has a much greater heat capacity than the air.

One suggestion for the long term cooling is that the arctic ocean has become partially land locked, leading to an ice cap and increasing the Earth's albedo.

The peer reviewed journals in oceanography show many long term cooling effects of oceans that show not just slowing of warming but actual reversing and to date, significant trends in reduction in warming.

Just for one example, if it turns out that, between melt of sea ice and Greenland ice, the North Atlantic Current slows or stops, we would expect to see fairly dramatically colder weather in Europe for a while, even thought this condition could be directly linked to results produced by GW (though in the long term, the warming would, presumably eventually overtake the cooling from change in ocean currents).

Phenomena such as El Niño or La Niña, which warm or cool the tropical Pacific Ocean, can contribute to short - term variations in global average temperature.

For instance, Mojib Latif of the Leibniz Institute of Marine Sciences in Germany and his colleagues published a paper in 2008 that suggested ocean circulation patterns might cause a period of cooling in parts of the Northern Hemisphere, even though the long - term pattern of warming remained in effect.

Or any time one has more ocean mixing, one gets cooler conditions [over short term] and anytime one has less ocean mixing, one gets warmer conditions [again over short term].

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.

But after several decades, carbon dioxide would begin diffusing from the ocean into the atmosphere, diminishing the cooling effect and warming the Earth in the long term.

In simple terms it seems that the effect of downwelling LR radiation is not to heat the ocean directly, but to turn the thin cool skin layer into a thermal insulating barrier and thus increase OHC by reducing heat transmission to the atmosphere.
