Actually our use of fertilizer and irrigation makes CO2 level a significant limiter on plant growth rates. CO2 fixation is so expensive that plants adapted to arid environments have developed a better way of doing it, C4 carbon fixation.
I found the study: https://wattsupwiththat.com/2017/04/05/study-suggests-increased-atmospheric-co2-creates-a-30-growth-in-plant-photosynthesis-during-last-two-centuries/ https://wattsupwiththat.com/2017/04/05/study-suggests-increa...
- dpark 9y agoThat's an interesting study but I fail to see that it supports your claim. There's no mention of C4 fixation in the article, nor any claim that CO2 fixation is a significant limiter for agriculture. The article claims 30% increase in general (not just agricultural), but also does not attribute all that simply to more available CO2. Your own claim is self-contradicting as you use arid environments as the basis for your claim. Agricultural environments where plants are irrigated are not arid, by definition.
