Good point.

Random thought experiment - how much should the global 'fund' be to attack greenhouse gas emissions. Not that it should be spent in proportion to % of total emissions, but I wonder what 3.3% of that number would be.

Say you spent 1T on cows, and spent it proportionally. That's a 30T fund overall. So around half from memory of what the US spent on the post 9/11 wars.
