The first number is the number of billions of dollars ($140B) in benefit that carbon dioxide added to global crop production in 2011.
The second is how many trillions of dollars ($3.2T) in benefits that CO2 added to global crop production between 1961 and 2011.
The third number is how many trillions of dollars ($9.8T) in benefits that carbon dioxide is projected to add to global crop production over the next 50 years.
In other words, as atmospheric CO2 has increased in recent decades, it has supported economic prosperity and the well-being of families and individuals by bolstering agricultural production around the world.
These figures come from a study of the impact on global agricultural production caused by the additional carbon dioxide that has been emitted into the atmosphere over the last five decades.
