Worldwide increases in plant growth are nontrivial—indeed, Idso and others attribute significant por-
tions of modern agricultural yields to increased atmospheric CO
2
.

And there is a lot of evidence for this;
observe the increases in crop yield when the following crucial crops were exposed to 300 ppm more CO
2
than is in the atmosphere.

, More Crop Growth
