The reality is that most farmers are not idiots, and the higher CO2 levels go the more productive our farms will be. That's not speculation, that's the measured conclusion of thousands of rigorous agronomy studies.

That will vary around the globe
The increase in CO2 and CO2 fertilization should be everywhere
Another figure

You're in denial of thousands of rigorous agronomy studies, over more than a century, which have measured the very large benefits of rising CO2 levels for agriculture. Of course, despite the benefits of elevated CO2, it's still possible to destroy agricultural productivity with bad governance.

Mao demonstrated that 60+ years ago, in pursuit of socialist utopia.
Gotabaya Rajapaksa proved it again in Sri Lanka in 2021. Sri Lanka's humanitarian and economic disaster is the poison fruit of climate alarmism.
Leftist politicians and climate activists are doing their best to lower crop yields, and return us to the days of mass famines. Most young people don't know much history, so they don't know what that's like. They're in for a very rude awakening, if the climate activists get their way. Compare:
β Covid-19 has killed about 0.1% of world population, so far
β The 1918 flu killed β2%
β WWII killed β2.7%
β But the global drought & famine of 1876-78 killed an estimated 3.7% of world population
Dutch farmers are some of the most productive in the world, but their leftist, climate-conscious government is doing their best to end that: https://reuters.com/business/environment/dutch-farmers-protest-plan-curb-nitrogen-pollution-2022-06-22/
So is Baby Trudeau's leftist, climate-conscious government in Canada: https://agweb.com/news/policy/politics/new-policy-forces-canadian-producers-cut-back-fertilizer
The Left and the Climate Industry are at war against agriculture, and against against humanity https://sealevel.info/learnmore.html?0=famine#famine
In fact, the Climate Industry is ultimately at war against science itself. The IPCC's 2022 AR6 Report explicitly promotes homeopathic climatology (TCRE/RCB), which is just as unscientific as it sounds.
Eli Rabett @EthonRaptor won't answer the question; so how about you, Willard? Do you agree with AR6 that CO2 which was FORMERLY in the air STILL has a warming effect? Or do you reject the IPCC's unscientific homeopathic climatology?
Climate activists are like modern Lysenkoists, pretending to be scientific, while shredding real science. Or are you going to pretend there's anything scientific about GISS "climate scientist" @DrKateMarvel Kate Marvel's "intersectional science"?

CO2 fertilization would βlift all boatsβ leading to similar slopes
Differences in implementing the Green Revolution would mean dissimilar slopes
What does the data say??

2/7. By displaying high productivity countries like the USA along with Niger, you forced OurWorldInData to scale the graphs so that it's hard to see the trend in Niger.
But if you display Niger alone, as I've done here, you'll see that cereal yields declined there until about thirty years ago, but they've improved since then (except for 2021).

The other major staple crop in Niger is cassava. Its yields have improved considerably.

4/7. That's probably because cassava benefits tremendously from additional CO2, especially in the dry conditions which are prevalent in most of Niger. Here's a paper about it:
https://www.tandfonline.com/doi/abs/10.1080/03650340.2018.1446523
Cruz et al 2018. Elevated CO2 reduces whole transpiration and substantially improves root production of cassava grown under water deficit. Archives of Agronomy and Soil Science 64: 1623-1634. doi:10.1080/03650340.2018.1446523

5/7. Most of Niger is desert or near-desert, which means most of its land is poorly suited for growing crops. Over the 60 year period shown, Niger's population increased by about 640%. As a result, the amount of land under cultivation drastically increased, resulting in more marginal land being put to the plow.
That, of course, can be expected to lower the average cereal yield per hectare. Nevertheless, other than a bad year in 2021, yields there have been improving since the mid 1990s.

6/7. That's probably because of the well-known fact that, in addition to improving production by CO2 fertilization, rising CO2 levels improve crops' water use efficiency and drought resilience. Here's a paper about wheat:

The science has been settled for over a century: elevated CO2 is tremendously beneficial for agriculture. The climate activists who refuse to acknowledge that established fact are science deniers.
