Human CO2 Emissions Are Supercharging Corn Yields
Higher CO2 levels also improve water-use efficiency in corn
Human CO2 Emissions Are Supercharging Corn Yields – California Globe

How can carbon dioxide, which has been portrayed as a dangerous pollutant threatening the very existence of humankind, be considered even remotely beneficial? Sadly, such a question can be expected from people – children and adults – who have been fed irrational fears in place of well-established science that shows CO2 to be an irreplaceable food for plants and necessary for all life.
Even some who recognize CO2 as sustenance consider increasing atmospheric concentrations of the gas to be potentially catastrophic, a view devoid of scientific basis and inimical to the fortunes of malnourished millions.
Corn, or maize, is foundational—along with rice, wheat, soyabean—to global food security, serving as a critical source of nourishment for both humans and livestock. Over the past few decades, increases in atmospheric CO2 from industrial emissions have tracked with notable boosts in corn yields.
But this remarkable impact of elevated CO2 is not just limited to C4 crops like corn. C3 plants, such as wheat, rice, potatoes, and soybeans, all rely on an enzyme called rubisco for carbon fixation. Rubisco’s efficiency improves significantly with higher CO2 concentrations because it reduces the enzyme’s tendency to bind with oxygen—a process known as photorespiration that limits productivity.
Consequently, elevated atmospheric CO2 often results in enhanced photosynthesis and biomass accumulation in C3 species, although to a lesser extent than with C4 plants. This is why rice and wheat yields can increase by up to 20-30% under elevated CO2 conditions. We have witnessed this in yield increases across most C3 food crops.
~Snip~
The relationship between rising atmospheric CO2 and crop yields is clearly a positive one. So, ignore fearmongering media headlines about toxic human CO2 emissions. You, your family and the industries that support our society have greened the planet with daily emissions of carbon dioxide, making food more plentiful and affordable for those grappling with poverty and everybody else.
Commentary:
It's no secret that plant life requires Carbon Dioxide to grow and the process includes the manufacture of the oxygen we breathe.
Atmospheric CO2 is roughly. 04% right now, or 420 parts per million.
Corn would grow best with 800-1,100ppm, varying by time of day and parietal.
Arguably we have too little CO2.
Science never has, nor ever will, be a friend of the Democrat Neo-Marxist Party.
Kamala will ban beans because it causes humans to emit methane and carbon dioxide. As to carbon dioxide, quit breathing. That will help her goal of reducing population. Eugenics in action. Only the, “Right People”, will be allowed to breathe...
