Humans have caused 1.5 °C of long-term global warming according to new estimates

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

Only 1% of GDP is agriculture, yet 100% of society relies on agriculture for survival. Because we don't have food shortages right now, GDP is heavily slanted towards things that don't really matter. You can't take that sort of monopoly money and try to influence the real world, if it were that easy then governments would be changing gas prices to win elections a lot more effectively.

Not disagreeing that there should be a lot more funding of climate change reducing endeavors, I just don't think that GDP should/could be an anchor to base that on.
