Maybe true, but academic.
Because still we would be converting what took millions of years of solar energy to create, back to the heat that would have existed before nature put it into storage as coal, as if nature never did anything with the solar energy at all.
This is why I emphasise creating hydrogen, which is our capability to do, direct from solar, at whatever efficiency is possible. It's a no brainer.
By that we would be re-doing what nature did, to bring down temperature, we would be replacing the solar energy stored in coal, and all the other fossil fuels, with our own human made version of that storage.
The good news is, we can do it in minutes, seconds, hours, days, weeks, months, rather than millions of years.
Even at 20 or 30 percent efficiency, this would be 20 or 30 percent efficient creation, activity which has a negative temperature impulse.
Whereas even 70 or 80 percent efficient use of coal, (Its nothing of the kind, 50 percent theoretical maximum) is still 30 or 20 percent destruction respectively.
This goes for any form of energy stored by nature on Earth, it can be stored in wind, hydro, geothermal, you name it, when we use it, we end up with a positive temperature impulse, can't get around it, unless it was us who did the storage, using solar - that is the one exception.
This is why hydrogen from solar looks inevitable, and actually really cool, it even converts to food in the form of Solein (Google it), and it filtrates drinking water, and it keeps all aerospace airborne.
Might be true we will use it almost as quick as we create it, converting it back to the heat it would have become if we never created it, but, the nature of creating and consuming anything is that we will accumulate it, because this is what drives us, each and every one of us, to minimise the uncertainty of supply of our own energy per the free energy principle of life, we need to metabolise to live 24/7, about 150 Joules per second, which we obtain via money, but we can never know the future, when our demand can rise to 600 or more Joules per second, in times of crisis for example, hence why we each have an instinct to accumulate money.
By accumulating hydrogen instead, as a species, we can and will pull the temperature back down, repaying what is effectively an energy debt we owe to the planet, just like every plant does thousands of times over, that had to withdraw energy from the Earth in its lifetime, before it formed leaves.
We just started to form our first leaves.
This is why I say we are on the cusp of being born as a species, if we recognise it, and allow it to happen, by starting to issue solar indexed stimulus, which is also the only way to preserve the energy value in money, whilst the economic product from solar inevitably ramps up, failure to monetise it by issue of money for free, the way the energy was received, for free, nothing asked in return, is resulting in inflation, which will not stop, until we do this.
Otherwise we will finish very shortly all as paupers, with Armageddon, killed by the hand of nature, because frankly, we were too stupid as a species, to be allowed to live.
