Or so that's the bottom-line conclusion of what the latest research is telling us, about the relationship between the PDO cycle [Pacific Decadal Oscillation], and the global-caching of the Global Warming warmth, deep within the reservoirs of the western Pacific Ocean.
Turn off the PDO Trade Winds -- and watch out for all that latent GW Heat, rising up out of the Ocean -- into the 'ocean of air' otherwise known as our Atmosphere.
And those Trade Winds are due to 'turn off' ... right. About. NOW. (... ie. soon.)
Looming Warming Spurt Could Reshape Climate Debate
by John Upton, climatecentral.org -- Feb 27, 2015
Humanity is about to experience a historically unprecedented spike in temperatures.
That’s the ominous conclusion of a vast and growing body of research that links sweeping Pacific Ocean cycles with rates of warming at the planet’s surface -- warming rates that could affect how communities and nations respond to threats posed by climate change.
Papers in two leading journals this week reaffirmed that the warming effects of a substantial chunk of our greenhouse gas pollution have been avoided on land for the last 15 to 20 years because of a phase in a decades-long cycle of ocean winds and currents.

You've heard about
reading 'tree-rings', to gauge ancient Climates -- well apparently those "Science Guys" just figured out how to do the same thing in the Oceans, using the 'fingerprints' left by ancient coral.
Clues in Coral Hint at Looming Temperature Spike
by John Upton, climatecentral.org -- Dec 22, 2014
Chemical clues in skeletons produced by coral growing at Kiribati contain a newly discovered warning. They caution of a global climate system that’s capable of drawing decades’ worth of hoarded heat out of the Pacific Ocean, and belching it back into the atmosphere.
A cryptic chemical weather log kept by Tarawa Atoll’s stony coral in the tropical Pacific archipelago has been cracked, helping scientists explain a century of peaks and troughs in global warming -- and inflaming fears that a speedup will follow the recent slowdown.
Added to a growing body of research, the newly published findings indicate that all it would take to trigger what could be an historically unparalleled period of rising global temperatures would be a shift in the winds. And that type of change in the intensity of Pacific trade winds appears to happen every 20 to 30 years or so.

Well that's putting it colloquially --
"decades’ worth of hoarded heat," "
belching" itself of out of the depths of the Pacific.
Well, excuse us!
If only we could 'trade' {cough} those winds for some 21st-century carbon capture tech, eh?
Pacific trade winds stall global surface warming -- for now
phys.org -- Feb 09, 2014
[...]
Heat stored in the western Pacific Ocean caused by an unprecedented strengthening of the equatorial trade winds appears to be largely responsible for the hiatus in surface warming observed over the past 13 years.
New research published today in the journal Nature Climate Change indicates that the dramatic acceleration in winds has invigorated the circulation of the Pacific Ocean, causing more heat to be taken out of the atmosphere and transferred into the subsurface ocean, while bringing cooler waters to the surface.
[...]
"But the heat uptake is by no means permanent: when the trade wind strength returns to normal -- as it inevitably will -- our research suggests heat will quickly accumulate in the atmosphere. So global temperatures look set to rise rapidly out of the hiatus, returning to the levels projected within as little as a decade."

[This is a schematic of the trends in temperature and ocean-atmosphere circulation in the Pacific over the past two decades. Color shading shows observed temperature trends (C per decade) during 1992-2011 at the sea surface (Northern Hemisphere only), zonally averaged in the latitude-depth sense (as per Supplementary Fig. 6) and along the equatorial Pacific in the longitude-depth plane (averaged between 5 N S). Peak warming in the western Pacific thermocline is 2.0 C per decade in the reanalysis data and 2.2 C per decade in the model. The mean and anomalous circulation in the Pacific Ocean is shown by bold and thin arrows, respectively, indicating an overall acceleration of the Pacific Ocean shallow overturning cells, the equatorial surface currents and the Equatorial Undercurrent (EUC). The accelerated atmospheric circulation in the Pacific is indicated by the dashed arrows; including the Walker cell (black dashed) and the Hadley cell (red dashed; Northern Hemisphere only). Anomalously high SLP in the North Pacific is indicated by the symbol "H." An equivalent accelerated Hadley cell in the Southern Hemisphere is omitted for clarity. Credit: Nature Climate Change.]
Don't you love it when those "Science Guys" figure out how to explain stuff, so that high school educated folks can understand it? {... sometimes.}
Will Looming Spikes Change Minds on Warming?

“Their results make sense to me, and are consistent with other evidence,” National Center for Atmospheric Research scientist Kevin Trenberth, who has published research dealing with the relationship between Pacific Decadal Oscillation (PDO) phases and surface warming, but who was not involved with either of the new studies, said. “The PDO clearly plays a key role -- and very high PDO values in recent months appear to signal a change.”
The growing body of research helps explain why ocean temperatures have been rising faster than anticipated, and, perhaps more compellingly, why land temperatures rose less than models had projected after the turn of the century -- a mystery, sometimes dubbed the warming “hiatus,” “pause” or “faux pause,” that confounded science until just the last couple of years.
“The hiatus is associated with the negative PDO phase -- with strong subtropical trade winds that pile the warm water up in the tropical western Pacific, and bury some warm water in the subtropics,” Trenberth said. “If you turn that off, then the waters warm more generally and over a shallower layer, with consequences for the atmosphere above.”
