Doubling, or more of plant growth, with a higher atmospheric concentration of CO2, is widespread across almost all plant species. Coffee is no exception, in some cases doubling the growth rate with an extra 300ppm of CO2 in the atmosphere: click here.

Not only do plants grow very well, but some have much improved protein values.
The Net Impact of Elevated CO2 and Concomitant Drought Stress on Sorghum Grain Biomass Production and Its Protein Content (9 May 2016)
Although grain biomass at harvest was not significantly impacted by the increase in the atmosphere’s CO2 concentration, its protein content was. Read on to learn by how much … and marvel at the answer!…
Yes, the title is correct, this is Post no 118 on pindanpost.com about the benefits of increased CO2 in the atmosphere! Go to co2science and see a lot more there. Canada, especially is benefiting by the billions, in wheat growing and oil refining.

Projected spring wheat yield change with (green bars) and without (red bars) CO2 effects for the period 2041–2070 (relative to 1971–2000 means) averaged from 11 locations across the Canadian Prairies under eight climate scenarios. Adapted from Qian et al. (2016).
