Let’s take the worst projection of $50 trillion over 20 years.
We can reduce it at least by half straight away because that is a cost to get ‘that stuff’ up the atmosphere without the price of ‘that stuff’ itself.
Then the actual cost of damage caused by the intentional or unintentional climate-changing procedures will mount to $408 billion/year in direct household costs, power infrastructure, and transport. So taking off $8 trillion over 20 years.
Next, there is the agriculture field. The price of direct and indirect crop response on the food market. The losses of human life. The subsequent migration crises and health crises. The ecological crises. It goes on and on.
If the militaries were to stop what they do in the atmosphere, we would end up in trillion dollars of surpluses that could be used to teach ourselves to be more “profitable” to the CREATOR than to the stock exchange.
