Fossil fuel volcano

I’m reading Light of the Stars “Alien Worlds and the Fate of the Earth” — Adam Frank.

I’m about halfway through and so far Frank has supplied mostly background in his attempt, I’m assuming, to present various models — based on our solar system’s mechanics and planetary variations — to determine the probability of exo-civilizations, in the galaxy and the cosmos in general.

Humanity’s existence and technological capability is dependent on a host of serendipitous “coin-flips” all landing up heads. Two of the biggest and most impactful are plate tectonics and the availability of a billion years worth of stored solar energy in the form of fossil fuel.

Plate tectonics ensures that CO2 is recycled. (CO2 is fixed from the atmosphere as sediment and rock, calcium carbonate — limestone, taken below the crust, disassociated and then re-released by volcanoes around the planet.) Without this cycle, CO2 would stay fixed, the planet would cool (as it has done in the past) (Nitrogen and Oxygen, 78% and 21%, are not efficient greenhouse gases) and that would be it for Earth.

And we all know what fossil fuels have done for humanity; taken an energy starved species and give it unlimited access to millions of years of nearly-free solar power. Without fossil fuels, humanity would have killed off all the whales (for fuel), burned down all the forests (for fuel), and never seen the explosive population growth that produced copious ideas resulting in constant technological advancement.

Part of his premise (I’m guessing) is to determine the impact and potential mitigation of global warming during the Anthropocene. This unusual release of extra CO2 that is warming the planet is, as far as he’s concerned, a potential solution to the Fermi Paradox: exo-civilizations might kill themselves off by their shear size and impact on their planet.

As I read Adam Frank’s setup I thought about a strange “ready for fiction” story line:

What would happen if a volcano suddenly spawned beneath one (or more) vast crude oil fields? Imagine if a Kilauea sized volcano burst up from the sands of Saudi Arabia. The heat and fire would start the oil burning. Thirty mile-high plumes of smoke would spread out for decades. Nuclear winter would descend. This is much like what a super-volcano would do, but a smaller volcano would suffice to trigger the calamity.

This is typical, don’t you think, this reading of anything and the extrapolation of a fiction story from the material? The “what if”s. I thrive on them.


On attenuating pending climate change…

The exploration, examination, and exposure of underlying climate change factors and concerns are all good and well and I support and applaud the balance of them.

However, the fact remains that humanity it not paying attention. China and India are building and using more and more coal fired electricity generation plants – with no end, or even reduction, in sight. Nat.gas and oil exploration and acquisition is continuing apace if not faster. Green energy alternatives are barely getting by; sure they continue to expand, but at a comparatively slow rate.

At this point additional alarm raising appears futile. A more rational approach might be to accept 450+ ppm CO2, accept increasing climate change impact, and get on with dealing with what most assuredly will be, rather than what we might hope (but fail) to prevent.

Face it, for the next 100+ years the planet will enter and experience a vastly different climate than what humanity has enjoyed for the last 10,000+ years. Humanity is just too short sighted to look out 2-10 generations and try and fix a future world. Fixes in the past, FDA, EPA, toxic dumping, pollution, were all single generation fixes. Climate change is so large, extensive and drawn out that most humans cannot fathom a fix.

So, prepare for the inevitable. This train has left the station and will not be making stops for the next 100 years.
