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.

Look at Covid fiscal response causing permanent 30% inflation in the last 4 years. The climate+demographic response money printing operation will be way bigger than that.

Most of the inflation from the last 4 years is attributable to Russia invading Ukraine. You can't have the largest natural gas exporter and second largest oil exporter invade one of the largest grain exporters without causing basically everything in a supermarket or restaurant to be more expensive.

Also shipping interruptions and lockdowns. Giving people money to not work is goin to have a much larger inflationary effect than giving people money to build things we want.

Source? Other than media articles repeating "due to the war in Ukraine"

Assuming you are talking about the USA, supposedly the USA is a net /exporter/ of grains [0]

[0] Not loading for me but https://www.ers.usda.gov/data-products/ag-and-food-statistic... . Copilot said "The United States is a net grain exporter. According to the USDA Economic Research Service (ERS), the U.S. typically exports more agricultural goods, including grains, than it imports1. In fiscal year 2023, the value of U.S. agricultural exports was $178.7 billion, despite a decline from the previous year. Grains and feeds are among the leading U.S. agricultural exports"

When the prices of fungible products rise in one place, they rise everywhere, otherwise there would be arbitrage opportunities everywhere.
