From the article ... > ACC has reduced global agricultural TFP by about 21% since 1961, a slowdown that is equivalent to losing the last 7 years of productivity growth. The effect is substantially more severe (a reduction of ~26–34%) in warmer regions such as Africa and Latin America and the Caribbean. https://www.nature.com/articles/s41558-021-01000-1 https://www.nature.com/articles/s41558-021-01000-1
