Looking into the numbers a couple if months ago I was surprised how little it costs to stop climate change.

On the order of 100-200 trillion USD. Which is roughly 100-200% of global yearly GDP. Or 2-5% of yearly GDP until 2050. This could well be provided by printing money at all the federal reserve banks.

This investment will likely bring in a positive return on investment because it reduces the negative climate impacts.

Without such investments the downstream costs in climate change adaptation will be very expensive

Printing money wouldn't work - you just make all of the existing money less valuable.

You are essentially forced borrowing from the cash holders of the printed currency. So yeah it would work. Wouldn’t necessarily be fair or popular; but it would work. Just have to account for the new money also being worth less because of the increase in the denominator of this equation.
