General Approach – Find the Cycles

My primary approach is to

seek out the causes of cyclic change
These will be controlled by orbital forcing, which is primarily gravitational by the Sun Earth Moon system, and variable solar radiance
I will suggest why the orbital forcing must be gravitational for volcanoes
Exceptional events do not repeat and are... exceptional
I am a physicist and professional engineer so only believes what the observations support, I won’t tell you what causes which, or expect consensual belief in my particular approach. It only takes one to prove everyone else wrong. There are no bad questions.
I will create a definite theory to test, and state conclusions
You can decide what to believe, with, perhaps, more research.

Moving along........

Theory Statement - Definite

“Submarine volcanism is significant, cyclically variable, and changes

global and regional climate by direct ocean heating, at a level capable of initiating and driving the sudden interglacial warmings of ice age cycles.”
Pre pub paper is at: http://dx.doi.org/10.2139/ssrn.3259379
Surface volcanoes have limited effect, the oceanic response quickly corrects the mainly cooling effects by evaporation & cloud albedo - 150W/m2
nb: Surface life maybe destroyed by fire & starvation, but the oceans soon stabilise the climate & nature recycles the carbon into new flora & fauna. Natural Re wilding
The majority of volcanoes, under the oceans, have quite different effects.
Oceans integrate & store the significant heat emitted continuously over extended periods across the whole active population and ocean volume
Volcanoes change the sea surface temperature hence global climate....

How much heat, and how much does it vary?

Some Facts About the Ocean Floor

The Earths tectonic plates mainly diverge

in the oceans, up to 24cm pa
Sea floor c.7km crust plus 0 > 120Km growing Lithosphere as plates age
Continental crusts are c.35km thick, depends who you ask
Thin, heavy, Oceanic plates are mostly subsumed by thicker lighter continents
Oceanic basaltic crust is no more than 200 million years old anywhere
The ocean is 70% of the Earth’s surface
The continents have 1,500 active volcanoes
The oceans should have at least 5,000
Perhaps more, given the shorter pathway through which magma must force its way

Why the World is Smooth and Round-ish

It isn’t rigid, its an

spinning oblate spheroid contained by gravity and CF
Most of the upper and lower mantle are deformable/visco-elastic hot rock
Under high pressure at many thousand degrees temperature, but mobile
Only the wafer-thin crust and Lithosphere is solid-ish - & the metal inner core.
NB: Crust is too thin to draw here, or represent on a screen/sheet of paper as a line (Visual)
The crust, atmosphere and oceans are held onto the mobile sphere by gravity, which gives them their pressure
Magma pressure is 10-30,000 Bar where it comes from, push, push....
So depth of oceans at exit has little effect (Deep ocean pressures are “only” 1,000 Bar)
The planetary body is in constant motion caused by gravitational orbital forcings

Earth is a flexible body wrapped in a wafer thin crust under a varying gravitational field that continually distorts the crust, while magma under huge pressure is constantly looking for ways out

The shape is constantly modulated by the gravitational orbital forcing of the Sun and Moon, currently there is a 0.5 metre per day solid tide as well as the liquid tides

Summary: What this means for Submarine Volcanoes

The ocean floor that oceanic

volcanoes must penetrate is thin, vs. continental
The driving pressure is huge and unaffected by the ocean above
Distance to the surface is 10% of the path through continental volcanoes
Crustal faults are continually stressed by gravitational tidal movement
That movement changes as orbital forcing changes
Forcing periods ranges from diurnal to the 100Ka Milankovitch eccentricity cycle
These factors help deliver an average output of 6.4 times surface volcanoes (*)
Largest is Hawaiian hot spot at 100 Million m3 pa volume accumulation
Average Output of a submarine volcano is about 28 million m3 pa (*)

But does it really vary?

nb: Author has so far declined to quantify the likely increase in emissions at Milankovitch maxima, but they are clearly substantial in the hundreds of percent. Most sustained during the 100Ka eccentricity maximum, most intense at the 41Ka obliquity maximum.

Volcanic maximums occur at Milankovitch orbital forcing maximums

How Much Warming is That? (Numbers at last!)

28x106m3/pa per volcano x

5,000 volcanoes = 140Km3 pa = 400 Billion tonnes pa
MUCH greater than ANY consensus figure, dwarfs the divergent ridge in-fill
Unit heat content:
Molten state: 1000 deg x 1,000kg x 1,000 Joules/kg deg = 1x109 Joules/tonne
Plus Heat of crystallisation = 400MJoules per tonne
Total Unit heat content is 1.4 Gigajoules per tonne
Hence Total Heat pa =5.5 x 1020 Joules per annum
Can raise 1m of the ocean by 0.36 deg ( = 5.5 x 1020 /(1x362x1012x1x103)x4.2x103)
0.034W/m2
Heat is added to the oceans, so retained for a considerable time, not lost, the intense heat will also cause increased overturning of the oceans

That’s how much, from volcanoes alone, and it varies by hundreds of percent at Milankovitch maxima

Can El Nino be Driven by Cyclic Volcanicity?

I additionally propose this

is the case, that is my definite theory
Galapagos region is a major volcanic hot spot, three plates meet here
El Nino events are characterised by warmer currents rising from the deep
What is warming them?
Viterito(i) has shown correlation between global seismic activity and El Ninos
Could orbital forcing cause El Ninos?
How much incremental heat is needed - TBD
Could Lunar eccentricity be the cause
Lunar forcings are the primary driver of change in liquid & solid Earth tides
Periods include 18.6y, 8.85y, plus other lesser forcings? 1998 – 2016 is 18 yrs
Now need to study El Nino cycle frequencies against all gravitational forcing
Watch this space .........there is no settled science.

What Controls the Planetary Climate? The atmosphere is primarily an effect

What Controls the Planetary Climate?

The atmosphere is primarily an effect of

dominant solar radiation, gravitational pressure and the much smaller heat input of internal heat, all kept in constant balance by the massive negative feedback to any change from the oceans, by changing evaporative cooling and the resulting cloud albedo. The atmosphere is not a control of climate, atmosphere is a medium in which these changes happen. A low heat capacity layer that determines the lapse rate to space.
The total global effect of the heat from submarine volcanic activity on the global surface climate is neither insignificant nor constant. The actual amount will become clearer as estimates of the total amount and variability of geothermal heat entering the deep oceans is better understood, combined with other significant natural cyclic oscillations of Earth’s multivariate systems that are not considered in climate models..

Primarily short term solar cycles, and long term orbital forcing cycles
Range and rate are consistent from cycle to cycle, including current warming
and turning point?

Proxies: Ice cores d18O, glacier position, tree rings, cosmogenic isotopes (Be10 and C14)
Direct: Weather stations, Satellites and probes, now focussed on oceans
Solar observations - Sun spots, now solar wind variation (Parker probe)
CMIP models presume most of last 2Ka change is due to anthropogenic causes
The geolgical observations say it isn’t
