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.

It wouldn't work linearly, but it still works. If you print 10% of your GDP in a year, you'll be sitting on only 1/11th of the GDP in cash at the end of the process.
