Elevated levels of CO2 make it difficult for plants to obtain the minerals necessary to grow and provide nutritious food..."Two main nutrients that are essential for human nutrition may be affected by this phenomenon. The first one is proteins built from nitrogen. The second one is iron."

Baloney. CO2 is the life breath of plants. The highest CO2 levels on the planet were the cause of the green world with megafauna supported by megaflora we do not have today.
Experts must be smoking something; was taught CO2 was the basic item for plant photosynthesis, without it they will die.
D’oh. Photosynthesis is what I meant...
Because modern corn is to make carbs and starch, to feed pigs and cattle to make protein.
If you want carbs eat corn, if you want protein eat a pig.
Simple evolved eating...don’t listen to the people who brought you the food pyramid, they faked that science for simplicity.

Sure, and less air is good for you.
The doubling and tripling of corn yields has much more to do with the hybrid genetically modified strains of maize cultivars than it has to do with carbon dioxide. The plant will continue to synthesize carbohydrates (sugars, starches and the cellulose structures that make up the roots, stalks and leaves), but in a different ratio than the old open-pollinated varieties, which makes for a kernel that may have lower proportion of protein content, but a larger proportion of sugars and starches.
During the Mesozoic era (The age of the dinosaurs), the Earth’s atmosphere had much higher CO2 concentration than current day, and that Era which was hundreds of millions of years in length, is noted for the explosion of life and overall warmth planet-wide. There weren’t even any ice caps on the planet, and the daily temps were around 120 degrees F.
Generally speaking, warmth is conflated with life, and to worry about it getting too hot is anti-science. We are never going to have a runaway greenhouse effect on Earth, as seen on Venus. We are too far from the Sun for that to happen.
Bull***t!
And even more importantly increased water hydration in fruits which carry very important vitamin cogeners. Vit C for example has additional cogener molecules that disappear rapidly in dehydrated fruit.
So, healthy plants make unhealthy food?
Sure...right...
We rotated our crops with pasture for our cattle. Still used fertilizer as needed.
Never worried for the CO2 was correct.π€
It would take some serious evidence to convince me daytime high temperatures were around a 120 degrees. That is some animal killing heat, when there is a fair amount of humidity in the air.
We only get that kind of heat, now, in desert areas, and very rarely.
Near 90, I could believe that.
With the ice caps gone, and much larger oceans, I would expect the temperatures to be much milder over the whole planet, while averaging higher. Just not as much variation.
Oceans are the great moderator in temperatures.
Exactly.
And this graph illustrates how a graph can be misleading.
It is a steep increase on the graph, making it look scary.
But the amount of increase is just 10 parts per MILLION, which is almost nothing.
Are you saying:
Exactly. Plants will take in as much or as little CO2 as they need...regardless of how much there is in the atmosphere.
Years ago, the oceans hadn’t warmed as much as computer models required to prove global warming. The warmists speculated that warm water was locked at the bottom of the sea by the colder water above. Apparently this was the well known scientific principle where warm water sinks and cold water rises.
Rather than reduced crop yields from less, or no, nitrogen fertilizers they will blame it on climate change.
Climate cnange causes everything bad, people. /s
Man is responsible for 3.4% of that 0.04%
The total amount of anthropogenic CO2 In the atmosphere is therefore 0.0014%
Completely eliminate man's contribution and the Earth's atmosphere still contains 0.04% CO2.
