• El Niño, a natural cycle of ocean warming, can exacerbate both flooding and drought, along with storm intensity, wildfires and other factors in the «vicious cycle» of climate change.

It plays a crucial role in the carbon cycle — the exchange of carbon dioxide between the atmosphere and the oceans — and in the buffering of blood and other bodily fluids.

For instance, perfect initialization of the state of the Atlantic ocean, a correct simulation of the next 10 years of the solar cycle, a proper inclusion of stratospheric water vapor, etc may be important for whether the next 5 years are warmer than the previous 5, but it has nothing to do with climate sensitivity, water vapor feedback, or other issues.

Coby, if the earth is warming as a result of increased periodic solar activity (or some other more complex reason) as suggested by the long term cycles mentioned above measured before man was on earth or industrialized, is it posssible that the observed increases in CO2 in the atmosphere are simply coming from warmer oceans, since liquids can not hold as much gas at a higher temperature than they can at lower temperature?

The late 20th century divergence is partly due to local anthropogenic warming and partly to other factors, such as longterm multicentennial linear trend in solar cycle frequency (thermal inertia of oceans and ice).

Expecting less than 5 % of Earths surface to filter the air mass from the other 95 % given actual air circulation patterns is patently absurd compared to natural CO2 scrubbing mechanisms like the biological carbon cycles, or Henry's law (which is leading to ocean acidification.

R Gates the skeptical warmist: «This really is exactly what Trenberth and others have been saying, though may may not so readily admit that at least 50 % of the 1976 - 1998 warming was because of natural ocean - atmsophere energy flux cycles.

1) It is such a smal part of Earth's energy system 2) It has such a low thermal inertia 3) It is so easily influenced by ocean cycles (i.e. the troposphere is the tail being wagged by the dog) 4) It is a poor metric (really a poor proxy) for climate sensitivity to GH gas forcing because energy quickly takes so many other forms in the system

«This really is exactly what Trenberth and others have been saying, though may may not so readily admit that at least 50 % of the 1976 - 1998 warming was because of natural ocean - atmsophere energy flux cycles.

The observation of a historically high level of TSI from 1961 to 2001 tends to fit with the theories set out in my other articles about the real cause of recent warming and the real link between solar energy, ocean cycles and global temperatures.

They have not only excised the water cycle, and excised rain from the carbon cycle, but have excised the whole atmosphere which is the heavy voluminous fluid ocean of real gas Air weighting a ton on our shoulders and in its place have empty space with imaginary ideal gas molecules travelling under their own molecular momentum at great speeds through this empty space miles apart from each other bouncing off each other in elastic collisions, no attraction, and so «thoroughly mixing».

The myriad of processes that transform energy, that result in the motion of mass in the atmosphere, in oceans, and on land, processes that drive the global water, carbon, and other biogeochemical cycles, all have in common that they are irreversible in their nature.»

In some way, that's the engine where all the other variations must be hanged (specially variations in albedo because of clouds - maybe connected with solar cycles as other authors are trying to prove -, variations in albedo because of sea ice extention, linked with the oceanic currents - as in the «stadium wave» that was presented by Curry and others, etc., variations in heat exchange between atmosphere and oceans, and so on.

Changes in sea level vary around the world and over time, because of the effects of ocean cycles, volcanic eruptions and other phenomena.

Whereas earlier it was believed that man's impact on the climate was gradual, and that the situation was deteriorating in a gradual way, now — in contrast to the previous report, which was being put together seven years ago — much more information has been obtained on ocean cycles and other natural fluctuations.

As Don Easterbrook and others note, hardly a significant length in temperatures that can cycle over hundreds and even thousands of years, caused by either solar input changes or circulations within the oceans.

Trees and other living organisms are key players in the global carbon cycle, a complex biogeochemical process in which carbon is exchanged among the atmosphere, the ocean, the biosphere and Earth's crust.

That's as far as I'm going with this, the next 1 or 2 years will be make or break for all theories — AGW, solar / ocean cycles, luke - warm, everyone, so there's no point going round and round on an argument that the actual observed climate will resolve one way or the other very soon.

But the «big climate picture» includes ocean feedbacks on all time scales, carbon and other elemental cycles, etc. and it has to be several decades before that is sorted out I would think.

They are mainly derived from the Shaviv reference (provided in the link above) that concludes that the solar signal is amplified as indicated by the magnitude of changes in ocean heat content (and other less direct measures) over the course of the 11 year solar cycle.

I read various reports regarding ocean current oscillations, solar influences and other possible natural contributors to these cycles.

Also — the ocean heat constant of 5 - 8 yrs calculated by Scafetta and others — is this related to (or reflected in) the ENSO cycle?

«A reduction in the rate of warming (not a pause) is a result of short - term natural variability, ocean absorption of heat from the atmosphere, volcanic eruptions, a downward phase of the 11 - year solar cycle, and other impacts over a short time period,» Cleugh says.

Other scientists dispute the necessity of life to the carbon cycle, for even without plankton calcium carbonate at sufficiently high concentration would precipitate out of ocean water.)

Because weather patterns vary, causing temperatures to be higher or lower than average from time to time due to factors like ocean processes, cloud variability, volcanic activity, and other natural cycles, scientists take a longer - term view in order to consider all of the year - to - year changes.

The ocean capacitor has a relatively steady flow or discharge to the atmosphere, which has the greatest short - term fluctuation seen in the ENSO cycle, but there are other cycles in this capacitor, such as the PDO and AMO.

While it is tempting to attribute the unexplained sea ice trends to other factors such as increased upwelling of relatively warm circumpolar deepwater (Thoma et al. 2008), an intensification of the hydrological cycle and increased ocean stratification (Liu and Curry 2010), or eastward propagation of sea ice anomalies (Holland et al. 2005), the observed northerly wind trends (Fig. 5a) are qualitatively consistent with the decrease in sea ice in the 30 ° W — 60 ° W sector.

The most likely candidate for that climatic variable force that comes to mind is solar variability (because I can think of no other force that can change or reverse in a different trend often enough, and quick enough to account for the historical climatic record) and the primary and secondary effects associated with this solar variability which I feel are a significant player in glacial / inter-glacial cycles, counter climatic trends when taken into consideration with these factors which are, land / ocean arrangements, mean land elevation, mean magnetic field strength of the earth (magnetic excursions), the mean state of the climate (average global temperature), the initial state of the earth's climate (how close to interglacial - glacial threshold condition it is) the state of random terrestrial (violent volcanic eruption, or a random atmospheric circulation / oceanic pattern that feeds upon itself possibly) / extra terrestrial events (super-nova in vicinity of earth or a random impact) along with Milankovitch Ccycles, counter climatic trends when taken into consideration with these factors which are, land / ocean arrangements, mean land elevation, mean magnetic field strength of the earth (magnetic excursions), the mean state of the climate (average global temperature), the initial state of the earth's climate (how close to interglacial - glacial threshold condition it is) the state of random terrestrial (violent volcanic eruption, or a random atmospheric circulation / oceanic pattern that feeds upon itself possibly) / extra terrestrial events (super-nova in vicinity of earth or a random impact) along with Milankovitch CyclesCycles.

On the topic of warmist scientists, one has to wonder why they define «climate» as a stretch of weather of 30 years when some of the ocean cycles take that long or longer and can run out of phase with each other.

And that's only the solar cycles, we haven't even touched on the major ocean oscillations, ENSO, volcanoes, or a raft of other possible factors that could seriously distort your very short base period (and the next few decades too, of course).
