# Contrasting long-term temperature trends reveal minor changes in projected potential evapotranspiration in the US Midwest

> A Nature Communications study published March 5, 2021 analyzed Midwest summer temperature records and found minimum temperatures rising while maximum temperatures have fallen, lowering vapor pressure deficit and potential evapotranspiration. Projections to 2050 suggest minor changes in evaporative demand with corn yield effects under 6%.

## Why it matters

Lower projected water stress reduces the case for expensive irrigation expansion and supports stable Midwest corn supply expectations, a mildly bearish influence on long-run corn price risk premiums.
