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

Worst part is 10x this money in real terms will be printed anyway and spent for exactly this purpose in the future, just way too late.

I fear you're an optimist.

I would be if I said it’ll work… at that point there won’t be anything to lose so might as well print.
