IRI scientists are presenting research at the AGU meeting on how climate influences global food systems. One study found that ENSO accounted for a little under one-fifth of global maize production variability between 1980 and 2010.
The finding quantifies how much global maize output swings with ENSO cycles, which helps buyers gauge weather-linked supply risk. It is background research and does not itself shift near-term prices.
