True to form Anders has commented that ” A recent paper by Lehner et al. shows that all large eruption since 1951 coincided with El Niño events.” Of course he completely fails to realise the importance of this and then digresses into a long irrelevant articles about global warming.
But as I have predicted that warming and volcanic activity are linked, this comment obviously made me think. There are as I suggest two possibilities:
- That the El Nino cycle in some way triggers volcanoes.
- That volcanoes trigger El Nino.
The first would obviously be the climate extremists preference … because by fabricating CO2 warming they could then get headlines of “humans trigger volcanoes” (in the same way everything is caused by CO2). And yes, I have predicted that crustal heating from changes in surface temperature would lead to volcanic activity. But the scale of change is far far too small. We are probably only talking about heat within a decade penetrating a few meters into the ground. Yes that will cause some stresses, but not enough I think to trigger geological processes.
But the second one is more interesting. Today I speculated that geothermal heat in the oceans would warm the bottom layers of the oceans and cause instabilities. In effect the bottom layer would heat up until it became lighter than the water above, and then we’d see a pretty rapid overturning of the ocean layers. This would explain the semi-periodic nature of the El Nino and other cycles.
But, if we were also to see an increase in geological processes (of which the volcano were but one symptom mid way through) … then potentially the geological processes might cause both the El Nino and the volcanoes.
However, I think that observation is just too obvious for some people:

James Edward Kamis has a theory somewhat like what you suggest. http://www.climatechangedispatch.com/why-el-nino-and-la-nina-are-one-continuous-geological-event.html?highlight=WyJrYW1pcyJd
“The reason these two very famous and supposedly different climate events look and act so similar is that they are actually not separate events, rather they are one geologically induced and continuous event. An event that is generated by a massive pulse of fluid flow from a major deep ocean fault zone located east of the Papua New Guinea / Solomon Island region.”
How megaplumes influence the climate much more than expected
Written by James Edward Kamis, guest post on 09 April 2015.
ventCCD Editor’s Note: Megaplumes, especially very large ones, have an underappreciated affect on climate and climate-related events, according to James Kamis, a geologist who has been working in the field for over 40 years. Below he describes how megaplumes, a powerful geologic force, have been relegated to the back burner in the ongoing climate change debate.
* * * * *
Megaplumes are massive three-dimensional cells of seawater that exhibit elevated heat and chemicals properties. They are generated by the sudden expulsion of super-heated and chemically charged seawater from geographically extensive and volcanically active deep-ocean regions such as major tectonic plate boundaries or upper mantle hotspots (Figure 1). The affected ocean region exhibits increased temperatures, altered chemical composition, modified currents, and increased turbulence, all of which act to vertically mix portions of the water column.

One example is the 1998 El Nino, which had a significant affect on the climate worldwide. This 1998 megaplume originated from a deep-ocean region east of Papua New Guinea that is known to be volcanically active and associated with several major plate boundaries.
The history of how megaplumes were discovered, researched, and then more or less ignored, however, is an interesting story itself. It went something like this: In 1986, scientists identified a massive cell of unusually hot and chemically charged seawater off the coast of Washington state. Baker et al discovered this phenomenon near the Juan de Fuca Ridge, and it was the first cataclysmic hydrothermal vent or megaplume.
The discovery shocked oceanographers and geologists for several reasons. First, it was of unprecedented size: 20 miles wide and 3,300 feet tall. Even more amazing, ocean temperature buoys showed that this entire cell was created in just 48 hours (Figure 2). It was stunning to witness this amount of energy released in such a short time period.

Extensive follow-up research proved that this megaplume was generated by the rapid expulsion of superheated and chemically charged water from a major deep-ocean geological feature, the Juan de Fuca Ridge. This pull-a-part fault complex is a portion of the plate boundary between the North American Continent and the Pacific Ocean Plate.
Scientists hailed the discovery of megaplumes as significant and a game changer as expressed in Discover Magazine:
Baker was particularly interested in learning more about megaplumes, observed only seven times before. Hot geysers of water, such as those on Axial’s flanks, rise only a few hundred feet above the seafloor, then diffuse like a pall of low-hanging smoke. Megaplumes, however, can soar more than several thousand feet off the ocean floor and spin like slow but gargantuan tornadoes. They can be 12 miles across and travel hundreds of miles. “It’s a bomblike event,” says Baker, who was among a group of oceanographers who discovered the phenomenon in 1986. Shortly thereafter, the researchers dubbed the underwater cyclones megaplumes.
The plumes have attracted interest for three reasons. First, they’re new. “You don’t often get a chance to find something that’s not known to exist,” Baker says. “And this isn’t some tiny feature, like a little rock. This is a whole giant process that no one knew about.”
Second, megaplumes stir up huge amounts of ocean, carrying minerals and gases and heat almost to the sea’s surface. Vertical mixing doesn’t happen easily in the ocean. Cool, dense water tends to stay near the bottom and warmer buoyant water near the top. As they rise from the ocean’s depths, megaplumes may bring energy and food to animals in shallow water. “They could be doing things to the energy of the ocean that we don’t even know about,” says David Butterfield, a chemist at the marine environmental lab.
Third, megaplumes move great distances horizontally too. In their travels, they may have helped some of the oddest and oldest beasts in the world colonize the planet. A hydrothermal hellhole like Axial may seem like a poor choice for a home, but it supports vibrant communities. Bacteria, which feed on methane and other noxious chemicals, provide sustenance for three-foot-long hollow tube worms and tiny clams. These critters can live only in hot spots on the seafloor, yet they have been found all over the world. How do they cross vast nutrient-free expanses of the sea to find new places to live? Megaplumes, which remain intact, spinning and drifting for months and traveling hundreds of miles, could be mobile ecosystems. “Maybe they’re like express buses,” Bake says. (In Search of Mega Plumes 1999)
Also during this time period (1983), the National Oceanic and Atmospheric Administration (NOAA) developed an entire group, the VENTS Program, to research hydrothermal vents. The group was largely composed and directed by oceanographers and geologists. They realized that earth’s oceans were not static pools of seawater; to the contrary, they now understood that the oceans were very dynamic, powerful and ever-changing systems much like the atmosphere. Additionally, they understood that geological forces played an important role in driving ocean dynamics and as a result likely affecting climate patterns. How much influence these geological forces had on ocean dynamics would have to be resolved with future research.
As research by the VENTS and other groups progressed, even larger megaplumes were identified, for instance in the Indian and Atlantic oceans. These plumes were immense: 44 miles by 20 miles by 5,000 feet tall. Calculations of total energy release per megaplume were astounding, clearly enough energy to significantly effect ocean dynamics. Eventually researchers identified a worldwide network of hydrothermal vents, mantle hotspots, and megaplume generation locations. Many of these features were associated with active tectonic plate boundaries or upper mantle hotspots.
At this point scientists were beginning to get a handle on the effect geological forces have on the ocean, and as a result the climate.
Then it happened.
Atmospherically trained climate scientists proposed the theory of manmade global warming. Seemingly overnight, these scientists had waylaid further investigation into the megaplumes’ effect on the climate.
Bolstered by environmental groups and fear-mongering tactics, climate scientists discarded years of sound geological research and its influence on the climate and replaced it with a new “consensus” theory: Namely, the climate could only be affected by man’s influence on the atmosphere. By default, geological forces were relegated to a minor secondary role in the great climate change debate.
Atmospheric-based solutions for all climate patterns and climate-related events were force-fitted into this shiny new manmade global warming theory. This force-fitting process worked well for a while, until it became apparent that not all climate events and pattern variations could be ascribed to the atmosphere.
Slowly at first, then more quickly during the last few years, climate scientists have started to “reinvent the wheel” so to speak. New and much more accurate data that demonstrates geological forces, including megaplumes, play far greater roles in altering the oceans and our climate is simply discarded.
A new theory,Plate Climatology, first proposed here, has emerged as the best explanation for the relationship between geological forces and climate.
Credible evidence increasingly supports plate climatology theory, which states that geological forces influence El Niños, Arctic sea ice melt patterns, hydrothermal methane and CO2 emission rates, deep-ocean currents, coral reef bleaching, plankton blooms, mega-droughts, and so on.
The discovery of geologically induced megaplumes played an important historical role in the evolution of climate science. To the satisfaction of field geologists, that notion is currently experiencing a resurrection.
James Edward Kamis is a Geologist and AAPG member of 40 years and has always been fascinated by the connection between Geology and Climate. Years of research / observation have convinced him that the Earth’s Heat Flow Engine, which drives the outer crustal plates, is also an important driver of the Earth’s climate.

Thanks for that.
I was having a moment last night where I suddenly thought “how can I write so much and be so certain when all I have is a few graphs”. The reason is because when you understand the features of the global temperature graph, you have very specific types of influences occurring at very specific points in the cycle.
Likewise, I know “natural variation” is a full explanation for almost everything that happens in the climate. However, when I try to explain what makes up that natural variation, I have phenomenon like El Nino with characteristic signatures – which suggest resonance of some kind, but also they require some kind of semi-random energy flow.
And when I start searching for things that could cause those signatures, there are very few candidates that give the right kinds of triggers. It doesn’t mean its the right mechanism, but its certainly one of the better explanations.

There does seem to be a link between Solar activity, Earhquakes and the PDO.

I have wondered for some time how much underwater volcanoes contribute to the warming of the oceans. Perhaps they are the triggers for the ice age? Cold air during solar minimums and the heat of the oceans transfer to the air until equalized? Add to that the westerlies blowing the heat to the hot spots until they can no longer accept more and so the excess wends it way back eastwards, when it travels north of the equator? Anyway, I’d like to thank El Nino because where I live, our snow has been drastically less, this year.
Damien Scott, I’ve been studying the electric universe theory and it has some promising points, IMO. Where it fails, IMO, is when it disputes that the Sun does not operate on fission but electricity. I can see that for the outer surface but on the interior, crushed by gravity, the pressured involved will produce fission and/or fusion. I can see parts of the theory having promise – explaining why we don’t need dark energy and dark matter to explain the expanding universe observations. I think it is a step in the right direction but it doesn’t answer all of my questions, as of yet. We’ll see.
