New research shows that the impending climate disaster puts the world in danger of growing too much corn and soy. People won’t know what starving is!
H/t to CO2Science
Qiao et al discovered that when temperatures are raised by a “catastrophic” 2 degrees C, and CO2 is raised to 700 unthinkable ppm corn (aka maize) increases its yield by a remarkable 25%. When hit by both high temperatures and extra CO2, soy bean yield increased even more — by 31%.
Presumably this means crop prices will fall and corn and soy may take over your garden. (So make sure you put in a solar panel to control those new weeds!)
Rumour that nutrient densities will fall — proved to be false. Increased temperature raised the oil content of both crops. And the combo of warmer weather plus CO2 increased most of the nutrients as well. Both crops had more phosphorus, potassium, iron, and zinc. There was a statistically small decrease in calcium in maize, so small it may not be there. The only mineral that definitely declined was manganese in soybeans, and as far as humans go, there is apparently no one on Earth who has a clinical manganese deficiency […]
