GeoEngineering won't save Marine Life!

Breakthrough solar cell, captures CO2 and sunlight and produces burnable fuel, SynGas.

If 25 Billion Tonnes of CO2 is removed from the atmosphere, it still won't save the marine life.

Roughly one third of all emitted CO2 ends up dissolved in the ocean!  We need to actively remove CO2 from the Ocean to save the marine life.

We need either distillation plants or Reverse Osmosis plants (as we need drinking water worldwide aswell!) that separate out the salts, magnesium carbonate(magnesite) and calcium carbonate (aragonite and calcite) and all the other salts, preferebly in areas where they can access the  deep ocean currents preferably near the surface that are laden with CO2 at higher pressures and lower temperatures.  We need to separate out the carbonates from the other salts. and create either rock (basalt) with the CO2 in it or put the calcium and magnesium back into the ocean.  The Co2 can be turned into SynGas (a mixture of CO and H2 , a burnable fuel)  by using a tungsten catalyst to change CO2 into CO and O2.  The O2 can be put back into the atmosphere.  H2O can be electrolyzed  with energy from sunlight (see above) with potassium salt to create H2 and O2.  The O2 can be put back into the atmosphere, and the H2 can be mixed with the CO to create SynGas which can be burned in gas turbines to create electricity.  The waste gases from the turbines, H2O and CO2 , can be recycled back into SynGas for no net CO2 emissions.  Or can be released into the atmosphere for a CO2 neutral source of electricity.
If we release the CO2 back into the atmosphere, for every tonne of CO2 removed from the ocean, only 1/3 would go back into the ocean!
  This needs to be done world wide!  We also have to capture all the CO2 at Coal and Methane power plants and reengineer the gas turbines to run on SynGas and recycle the waste gases back into a fuel to improve fuel mileage and achieve net zero CO2 emissions!

Can we save the oceans from Ocean Acidity Climate Shock?!

Does anyone really, truly,  care about marine life, as long as we've got tins of tuna, and sardines, on the supermarket shelves?

Answer honestly!

[Tim the Plumber]

Given that the increased CO2 in the oceans is plant food which will result in increased life in the oceans and thus increased deposition
of limestone the new balance point where the level of CO2 coming into the ocean will be equal to the amount being lost to the deep
ocean will happen long before the oceans become acidic there is nothing to worry about.

The oceans are alkaline. It would take a vast amount of CO2 to make them acid. This has never happened in the past even when there
has been vast amounts of CO2 in the air.

Find something else to panic about.

The "Climate Change" people want to panic.   They are using "Climate Change" as a substitute for religious fervour.  They want to believe in the "End of Days".

All this stuff about "saving marine life"  with "Ocean Engineering"!

I don't want to save marine life - I want to eat it in a tuna-sandwich.
