3,477,403 submarine volcanoes worldwide

More than 139,000 of those are active, pumping vast amounts of CO2 into the oceans

Lava contains a surprising amount of carbon dioxide, says consulting geologist Timothy Casey.  In fact, CO2 is the second most abundantly emitted volcanic gas next to steam.

Carbon dioxide emissions from volcanoes – especially from underwater volcanoes – dwarf anthropogenic (man-made) contributions sources, says Casey.

Since seawater in the vicinity of hydrothermal vent systems is saturated with carbon dioxide, and since seawater elsewhere is not saturated with CO2, it stands to reason that this saturation came from the hydrothermal vent system, Casey argues.

In point of fact, says Casey, carbon dioxide escapes these hydrothermal vent systems in such quantities that it sometimes accumulates in submarine lakes of liquid carbon dioxide. There is nothing to prevent that superheated carbon dioxide from dissolving into the seawater or otherwise making its way to the surface.

As part of his argument, Casey points to a study by Hillier and Watts. After surveying 201,055 submarine volcanoes, they estimated that a total of 3,477,403 submarine volcanoes exist worldwide.

Of those 3,477,403 underwater volcanoes, Casey estimates that 139,096 are active.

More than 139,000 ACTIVE underwater volcanoes. No wonder CO2 levels are rising.

    It’s also a peer reviewed fact that volcanism significantly rises during solar grand minimums due to the gravitation effects of the Sun’s trefoil orbit on the Earth’s tectonic plates during this first cycle of the Modern Grand Minimum.
    I would expect that atmospheric CO2 will continue to rise as the minimum progresses, even as the World Wide Avg. temperature falls by 1.5C over the next 30 years, as it has done during previous Grand Minimums during the whole of this Interglacial period.
    We now need accurate measurements of EUV, Sun Spots, Solar Energy output, rather than the Green Anarchist fictions trumpeted by the Anglo Saxon Met offices, designed to maintain the Green taxation base of the Anglo Saxon Bankrupt Governments.
    Humanity needs science to return to working for the betterment of Human kind rather than this unedifying scramble for biased government grants which are used to promote personal self-aggrandisement at the expense of science, and more importantly Truth as opposed to the climate lies we are being fed.

  2. Maybe planet nine be a cause oc the ocean warming not just the sun affecting core flows.Just last week 5 trans Newtonian objects were spoted 110 degrees moving against the plane movi clockwise in the solar system. Scientists cannot figure it out.

    • Do you mean trans-Neptunian? Yeah there do seem to be a lot of objects out there moving in directions that are not the norm for our solar system. Go far enough out, of course, and you reach the Oort Cloud, where the comets originate and they are just a spherical shell of early Solar System remnants that are moving in literally any and all directions. This could be the reason for some larger bodies moving contrary to the rotation of the Solar System

      • Are they not just captured bodies, which explains their retrograde orbit? Nothing mysterious there. Venus and Uranus spin is retrograde, but they are still orbiting the Sun in the same direction as the other planets. Planet 9 is still a hypothetical planet. I would be very surprised if it was having an ‘effect’ on anything, mrc. Let’s not jump to conclusions here. Leave that to the AGW lot. They’re very good at that. 🙂

  3. If we accept that changes to the location of the Solar System BarryCentre, which the Sun attempts to follow via an abrupt Trefoil Orbit, which then changes the energy output of the Sun, caused by the seven thousand year orbital progression of the Jovian Gas Giants around the Sun and the Solar System BarryCentre.
    Then Planet Nine, if it is a Jovian class sized Newtonian object on a ten thousand year orbit may be the gravitational kicker to start and end an Interglacial in the same way the four existing Jovian Gas Giants moderate the Sun’s activity into three distinct phases as per the paper on Gleissberg cycles on much shorter time scales.
    The energy moderating force on the Sun is Gravity and the Sun’s changing orbit around the Solar System BarryCentre.

  4. This reminds me of volcanic pipe near the Spanish river near Sudbury , Ontario. It is a volcano with alkali lava that is roughly 50% calcite. The deposit is a source of CO2 . 21.3% in the assay.

    Spanish River Carbonatite is a rare magmatic, alkalic deposit characterized by:
    Chemical and mineralogical complexity:
    o Loosely bonded nanocrystalline calcium, potassium and phosphorous are the main minerals.
    o A wide array of trace elements including rare earths.
    No radioactive or toxic metals.
    Disproportionate concentration of:
    o Hydrolysable bases (Ca, K, Mg, Na etc.).
    o Volatiles (H2O, CO2).
    o Lithophile elements, (defined as a strong affinity for oxygen, having a greater free energy of oxidation).

    The most naturally fertile regions on Earth exist where these characteristics (mineralogical-biological interactions) are found in association with extremely reactive alkalic rocks The essential primary minerals contained in these rocks are the first to be utilized in biological systems. These extremely fragile minerals do not survive geological transformations (physical, chemical or biological) and break down easily to supply the ecosystem with nutrients.

    The point to all this is that CO2 is available from all volcanoes active and extinct and in large mounts. In the Eifel volcanic field there are cold geysers that are driven by CO2.

    Considering how long this has been occurring the idea that CO2 is a serious problem should be dismissed as nonsense.
