100% nonsense. It amazes me that even the smartest climate activists are uniformly ignorant of agronomy!
Of course most crops are C3 & eCO2 is hugely beneficial for them. But C4 crops also benefit greatly from eCO2.

Here's a study which measured large benefits of eCO2 for corn:

They're often grown in arid climates, like the Sahel, because they're quite drought-hardy.

eCO2 is ESPECIALLY beneficial under those conditions, because it makes both C3 & C4 plants need less water.

sciencedirect.com/science/articl…

EXCERPT:
"There have been many studies on the interaction of CO2 and water on plant growth. Under elevated CO2, less water is used to produce each unit of dry matter by reducing stomatal conductance."

But C4 crops are favored for their drought-hardiness & eCO2 is especially beneficial in dry conditions.

In fact, eCO2 even helps pine forests withstand bark beetles.

In fact, scientists call warm climate periods "climate optimums."
