Interpretive Summary:

Technical Abstract: Small-scale experiments indicate that ozone causes significant damage to crops, but it is not straightforward to scale these experiments to regions due to many assumptions involved. An article has been accepted to Nature Foods that avoids this issue by using observed regional data to estimate crop loss to ozone. This piece is a summary of the authors finding meant for a general audience, published separately from the study authors' manuscript. The authors find losses range from 2 to 22% depending on the crop and region. Notably, they find that losses have declined as ozone concentrations have decreased, but there are still substantial losses due to current ozone concentrations.
