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

Although a useful metric about the size of economy, I dont think this gives any metric of the level of liquidity, or size of investment, or austerity measure necessary to change it

It doesnt give any indication about the level of debasement of currency to accomplish it to that scale, to pay for what? to whom?

and even if you identified some answers to those questions, this is where the disagreements are, ranging from cordial disagreement to outright denial of a problem

but most of it comes down to who is paying, for what, why are we paying, will it change anything, and how do we make a return on it
