Naturally occurring interannual and multidecadal shifts in regional ocean regimes such as the Pacific El Niño - Southern Oscillation, the North Atlantic Oscillation, and the Atlantic Multidecadal Oscillation, for example, are bimodal oscillations that cycle between phases of warmer and cooler sea surface temperatures.
Speculative frenzy rarely cools down without the bear phase of the credit cycle showing up.
4) The AMO might be heading for a cool phase, and this combined with a continued cool PDO, on top of a weak Solar Cycle 24 could prove interesting.
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.
And Now we have the beginning of a cool phase starting sometime in 2007 as the PDO reversed and other cycles seem about to follow suit.

There's the gas of the atmosphere additionally which the refrigerant, cycling through it's phases, also cools.
Since the PDO entered its 30 - yr cool phase in 2008, it would tend to support future falling temps as indicated on the graph, especially in light of weakening solar cycles which also started from 2008, leading to, in scientific parlance, a super-duper double whammy....
In 1975 Wallace Broeker (the guy who first used the phrase «global warming», predicted a rapid transition to warming in the 1980s, caused by a combination of rapidly rising CO2 emissions and a natural temperature cycle (derived from work on Greenland ice cores at Camp Century) which showed a rapid warming phase up to 1940, followed by the cooling phase which was attenuated by CO2.
The warming cycle of the past three hundred years is likely over, or nearly over and we are entering the next several hundred year cooling phase.
If the slower cooling phase is still evident (as there is more CO2 in the atmosphere during the peak of the warm cycle which should keep temperatures warmer for longer) then this should constitute empirical evidence for CO2's effects on the climate.
There are two main explanations for the 1940s to 1970s global temperature stagnation (or slight cooling): aerosol forcing and the negative phase of an ocean cycle known as the Atlantic Multi-decadal Oscillation (AMO), with the former contributing more than the latter.
«The global warming in 1970 - 1998 was merely a phase in the 60 - year cycles of natural warming and cooling,» Dr. Bashkirtsev says.
Scientists studying oceans demonstrate that the recent warming, to the end of the last century, is part of the natural cycle of oceanic oscillations and predict a thirty year cooling phase.
The study Harris authored found that «the data... clearly shows the nominal 100KY cycle for glaciation and the interglacial phases and it shows that we have reached the end of the typical interglacial cycle and are due for a sudden cooling climate change.
«The cooling phase will last for about 45 - 65 years, for four to six 11 - year cycles of the Sun, after which on the Earth, at the beginning of the 22nd century, will begin the new, next quasi-bicentennial cycle of warming.»
From here to item 20 is simply the reverse (cooling) phase of the same global climate cycle described in items 1 to 10.
The paper being discussed here makes the claim that the current hiatus in warming is due to the heat going into the Atlantic ocean as the Atlantic ocean is currently in the 30 year cooling phase of it's ~ 60 year warming / cooling cycle.
If that is the cooling phase of a natural cycle, and that cycle was in a warming phase during the late 20th century, then about half the late 20th C warming was natural, and half due to AGW.
So in the past, as shown from the ice core records, when the interglacial cycle reaches its cooling phase and the atmosphere starts to cool in spite of increasing CO2 levels (proven that changes in CO2 lags temperature change by about 800 years) you are saying that didn't happen?
«Thirty - five vertical temperature profiles during the warming and cooling phases of the diurnal cycle (Fig. 6) were obtained by free - rising profiler at low wind speed.»
I did suggest some time ago to Dr Bob Tisdale across at WUWT that perhaps a difference in the rate of energy loss during both the warming and cooling phases of ENSO and PDO cycles, because of a change in the atmospheric albedo, could provide a physical explanation for the correlation they were describing, but the hypothesis was not favoured.
By analyzing a number of time series of phenomena influenced by climate, they found that the earth has global climate cycles of 50 - 70 years with an average of about 60 years and which have cool and warm phases of 30 years each.
They show that increasing world fuel consumption (i.e., increasing CO2 emission) does not correlate with cool and warm phases of the 60 year global climate cycle.
With a new awareness that climate could change in serious ways, in the early 1970s some scientists predicted a continued gradual cooling, perhaps a phase of a long natural cycle or perhaps caused by human pollution of the atmosphere with smog and dust.
