# How Much Do Climate Fluctuations Matter for Global Crop Yields? | Columbia Science Commits

> A new study in Science Advances finds that ENSO has caused widespread, simultaneous crop failures in corn, wheat and soy across breadbasket regions. It estimates ENSO drove nearly 18 percent volatility in global corn production from 1980 to 2010.

## Why it matters

The finding challenges the assumption that distant breadbasket failures are unrelated, implying correlated global supply shocks that can lift corn, wheat and soy prices together during El Niño years.
