Indeed, and this article highlights a very thorny political issue - if a carbon tax was in place, would this finding mean it would have 100x the impact on food prices that was modeled?
If a carbon tax is so high that fertiliser becomes uneconomic to use (which is sorta the goal of a carbon tax at some point, to squeeze people who emit so they behave differently) that is maybe going to start impacting food prices. Somebody is going to feel that. As a political topic fertiliser needs careful handling.
