I just had to include Bob's graphs for the Arctic Ocean SSTs and the Southern Ocean SSTs.  Perhaps this has been mentioned before,
but it can't hurt to mention again ... note the abrupt shift in anomaly sign in 2007 in both oceans ... and the extreme variance in both.

So what happened in 2007?  We hit solar minimum yes ... but am I missing something?  Do others have a clue to what I'm missing?
Because it seems big.

'The blob': how marine heatwaves are causing unprecedented climate chaos

First seabirds started falling out of the sky, washing up on beaches from California to Canada.

Then emaciated and dehydrated sea lion pups began showing up, stranded and on the brink of death.

A surge in dead whales was reported in the same region, and that was followed by the largest ever toxic algal bloom seen along the Californian coast. Mixed among all that, there were population booms of several marine species that normally aren’t seen surging in the same year.

Plague, famine, pestilence and death was sweeping the northern Pacific ocean between 2014 and 2015.

This chaos was caused by a single massive heatwave, unlike anything ever seen before. But it was not the sort of heatwave we are used to thinking about, where the air gets thick with warmth. This occurred in the ocean, where the effects are normally hidden from view.

Nicknamed “the blob”, it was arguably the biggest marine heatwave ever seen. It may have been the worst but wide-scale disruption from marine heatwaves is increasingly being seen all around the globe, with regions such as Australia seemingly being hit with more than their fair share.

It might seem strange given their huge impact but the concept of a marine heatwave is new to science. The term was only coined in 2011. Since then a growing body of work documenting their cause and impact has developed.

Ocean temperatures have been consistently rising for at least three decades. Scientists believe that global sea surface temperatures will continue to increase over the next decade as greenhouse gases build up in the atmosphere.

According to a report by the International Union for Conservation of Nature released last week, the Southern Hemisphere has experienced intense warming over the past decade, with strong heat accumulation in the midlatitude regions of the Pacific and Indian Oceans.

The soaring temperature of the oceans is the “greatest hidden challenge of our generation” that is altering the make-up of marine species, shrinking fishing areas and starting to spread disease to humans, according to the most comprehensive analysis yet of ocean warming.

The oceans have already sucked up an enormous amount of heat due to escalating greenhouse gas emissions, affecting marine species from microbes to whales, according to an International Union for Conservation of Nature (IUCN) report involving the work of 80 scientists from a dozen countries.

They must think that nobody thinks when they read these things.  First they say ...

For several decades, more energy has been absorbed than emitted at the top of Earth’s atmosphere. According to Gregory Johnson, an oceanographer at NOAA, the rate of energy gained between 1971 and 2010 was roughly equal to the power required to run 140 billion 1,500-watt hair dryers over the same number of years. The rate has only increased in the past decade.  This excess energy has largely been sucked up by the oceans,

Doesn't this suggest a solar source??

Then they say ...

The oceans act as Earth’s enormous heat sponge, sheltering continents and the people who live on them from atmospheric extremes. The near-surface ocean takes only decades to warm in response to elevated greenhouse gas concentrations,

Perhaps they just left out something.

The Physical Flaws of the Global Warming Theory and Deep Ocean Circulation Changes as the Primary Climate Driver

Abstract

Increases in CO2 and other greenhouse gases will not be able to bring about significant climate
disruption in the next 75-100 years. The main problem with the Anthropogenic Global Warming
(AGW) theory is the false treatment of the global hydrologic cycle which is not adequately understood
by any of the AGW advocates. The water vapor, cloud, and condensation-evaporation assumptions
within the conventional AGW theory and the (GCM) simulations are incorrectly designed to block too
much infrared (IR) radiation to space. They also do not reflect-scatter enough short wave (albedo)
energy to space. These two misrepresentations result in a large artificial warming that is not realistic.
A realistic treatment of the hydrologic cycle would show that the influence of a doubling of CO2 should
lead to a global surface warming of only about 0.3°C – not the 3°C warming as indicated by the climate simulations.

The global surface warming of about 0.7°C that has been experienced over the last 150 years and
the multi-decadal up-and-down global temperature changes of 0.3-0.4°C that have been observed
over this period are hypothesized to be driven by a combination of multi-century and multi-decadal
ocean circulation changes. These ocean changes are due to naturally occurring upper ocean salinity
variations. Changes in CO2 play little role in these salinity driven ocean climate forcings.

Nice eulogy here from Phil Klotzbach: Dr. Bill Gray – A Eulogy

The oceans act as Earth’s enormous heat sponge, sheltering continents and the people who live on them from atmospheric extremes. The near-surface ocean takes only decades to warm in response to elevated greenhouse gas concentrations,

Yet we know that is not true as the oceans are if anything cooled by any 'downwelling' infrared as it causes evaporation removing latent heat of evaporation and so speeds up the cooling from the hydrologic cycle. As more than 66% of the surface of the Earth is water the downwelling infrared will cool the Earth overall. The clouds formed by the condensation of the water vapor will then act to increase albedo and reduce the amount of incoming higher frequency energy that could have warmed the oceans.

But the CAGW proponents, all blowing on their coffees to keep them warm, do not seem to do basic observational science.

I posted something a whole back which described n atlantic cooling as a function of wind mixing the water column...

This guy take the whole description of this possible effect and analyses to a pretty in-depth level, what you all think? Plausible conclusions??

I'm open to anything other than the "CO2 is the only driver of climate" theory.

Interesting read; shame I'm not qualified to comment.

"The ocean is an incredibly dynamic, constantly changing three dimensional system." Like the rest of the climate, apart from the number of dimensions?

Good article Acid.  

As we already saw, more wind results in cooling because of upwelling/mixing. Therefore, the most logical conclusion here is that warming seas enhanced global wind speed and that global wind speed in turn started the cooling process.

Only thing I'd add would be ... and if the sun cools down when you're already cooling the oceans, you're screwed.

Not sure I'm a fan of "logical conclusions" any more .......
