«it is necessary to disentangle the simultaneous overlapping positive and negative effects of solar variation, PDO / ENSO and
the other oceanic cycles.
At present they are limited to guesses about ENSO but have nothing adequate about
any other oceanic cycles and nothing about air circulation shifts apart from seasonal changes and a simple observation that warming moves them poleward.
«from time to time
the other oceanic cycles can operate in the opposite mode to PDO / ENSO thereby offsetting it until any lag is worked through.
Before it is safe to attribute a global warming or a global cooling effect to any other factor (CO2 in particular) it is necessary to disentangle the simultaneous overlapping positive and negative effects of solar variation, PDO / ENSO and
the other oceanic cycles.
It logically follows that, from time to time,
the other oceanic cycles can operate in conjunction with PDO / ENSO to emphasise the effect on the global temperature.
Seasonal weather fluctuations also depend on factors such as proximity to oceans or other large bodies of water, currents in those oceans, El Nino / ENSO and
other oceanic cycles, and prevailing winds.

Other studies have linked these
oceanic cycles with earlier snowmelts and warmer winters in California since the 1940s, and with a decline in California's coastal fog since the early 20th century.
It will be hard to identify because, as I have mentioned in my
other articles, the filtering of the solar signal through the various
oceanic cycles is neither rapid nor straightforward.
Do scientists know enough to separate human factors from the numerous, powerful, interrelated solar, cosmic,
oceanic, terrestrial and
other forces that have repeatedly caused minor to major climate changes, climate
cycles and weather events throughout human and geologic history?
The natural
cycles can not be reasonable removed until it is known what in hell drives them, how long they last, what sort of feedbacks do they create independently and among
other cycles, how they interact with CO2 and
other first order anthro - forcings that alter the earths surface, atmospheric and
oceanic physiobiochemistry.
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.
Other studies have linked these
oceanic cycles with earlier snowmelts and warmer winters in California since the 1940s, and with a decline in California's coastal fog since the early 20th century.
Sometimes the solar
cycles operate in conjunction with the
oceanic oscillations but at
other times they work against each
other.
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 C

It will be hard to identify because, as I have mentioned in my
other articles, the filtering of the solar signal through the various
oceanic cycles is neither rapid nor straightforward and it appears that the effects are caused not by solar irradiance in itself but rather by changes in the mix of wavelengths and particles from the sun as solar activity varies.
Obviously
other very powerful factors play huge roles, such as natural
oceanic cycles and weather patterns over all Arctic atmospheric layers.
