Ever wondered how the whole planet could suddenly get warmer during an El Nino, and then suddenly cool again? William Kininmonth has the answer. As I read his words Im picturing a major pool of stored coldness (bear with me, I know cold is just a lack of heat) which is periodically unleashed on the surface temperatures. The vast deep ocean abyss is filled with salty and near freezing water. In years where this colder pool is kept in place we have El Ninos, and on years when the colder water rises and mixes up near the surface we have La Ninas. The satellites recording temperatures at the surface of the ocean are picking up the warmth (or lack of) on this top-most layer. Thats why it can be bitterly cold for land thermometers but at the same time the satellites are recording a higher world average temperature, due to the massive area of the Pacific.
In other words, just as youd expect, the actual temperature of the whole planetary mass is not rising and falling within months, instead, at times the oceans swallow the heat on the surface and give up some coldness. At other times, the cold stays buried deep down and the heat can collect and loll about on the surface.
William Kininmonth was chief of Australias National Climate Centre at the Bureau of Meteorology from 1986 to 1998. Below, he describes how a vast pool of cold water filled the deep ocean abyss over 30 million years, and why this water and the currents that shift it have a major impact our climate. The so-called Bottom Layer is not just pockets or pools, it forms around Antarctica, then sinks and flows along the bottom all the way across the equator and into the Northern Hemisphere. Bear in mind the average depth of the ocean is around 4 kilometers, and yet almost all the water below a depth of 1000 m is around 4°C or colder. The Antarctic Bottom Water itself is close to 0°C. The equivalent heat energy of the entire atmosphere is stored in just the top few meters of water. It gives us all some perspective on the relative importance of different factors affecting the climate. His thoughts are in response to the latest debate essay from Dr Andrew Glikson, so the figures 1 and 2 come from that article.
Kininmonth points out that small changes in the rate of the Thermohaline Circulation (also known as the Oceans Conveyor Belt) makes a huge difference to all corners of the globe, and that the climate models make large assumptions about the flow of energy. Since the cold bottom layer was created by a kind of Antarctic Refridgerator (set into play by the circumpolar current) this colossal cold pool of water will presumably hang around until the continents shift. Thats quite a few election cycles.

Of particular interest to me was the second panel of his Figure 1(see below). It shows that the temperature of the deep ocean fell from 12°C to 0°C , but without explanation. Bob Foster has spoken of this regularly the opening of Drake Passage and the isolation of the Antarctic continent from the warmer tropical surface temperatures by the Antarctic Circumpolar Current. This means that winter sea ice forms around the Antarctic coastline, and expels salt into the surrounding sea water which increases the salinity and density of the near freezing water under the sea ice. There is only one way for that cold saline water to go and that is down to form Bottom Water.

Next question. What drives the deep oceans?
Excellent question. Quarks, I believe.

Sorry, guys, it’s the Sun that does it.
If you take it down to the most basic level it’s all running on testosterone.
That one statement says volumes.
Well, yeah, and so does the sun, and the rotation of the Earth.
Good job, Ernest. Thanks!
Agenda driven research?
Cheney’s Halliburton Hurricane Horror, of course.
Someone or something is causing these “climate scientists” to look at the earth through the wrong end of the telescope. ;^)
"The ocean surface layer is a thin lens of warm water overlying the cold abyss"...and yet, the so-called scientists -- who are merely politically motivated demagogues -- pushing the global warming Big Lie used to claim (with no basis whatsoever) that the reason the Earth wasn't warming as they'd "projected" (a.k.a. made up crap) was because the heat was being sequestered in the depths of the oceans, and was going to suddenly appear and bite us in the ass. Naturally that just delayed the inevitable, as expensive studies were made -- studies which found that the claim was baseless, yet another tissue of lies.

Interesting article. I have for a long time believed the deep oceans as being the regulators this article brings out.
