Earth's recent climate spiral.

[Anomalocaris]

Soil isn't just a carbon trap, it's a dwindling commodity that takes roughly 800 years to produce an inch of.  There are no known shortcuts.

Good night, godspeed...and good luck....lol.

There are known short cuts.    The native Americans of Amazon rain forest figured it out about 500 BC.   

Using Stone Age tools and with a population of just perhaps one million at most, they systematically manufactured the richest agricultural soil in the new world, out of some of the most nutrient poor natural soil in the world, to cover an area larger than France to a depth of 2 meters and more over a period of about 1500 years.  

Not only does the artificial soil they manufactured, called Terra preta, rival the most fertile agricultural soil in. Euroasia, such as the fabled chernozem soil of Ukraine, in fertility.    it also has remarkable self-regenerative properties unrivaled by any known naturally fertile soil.    They can regenerate themselves at a rate of 1cm a year.  From a thin priming layer a inch deep, they can regenerate enough for most agricultural crops in 25 years.
