Residents of the Midwest have long been familiar with the phenomenon known as 'corn sweat,' where late-summer humidity spikes due to corn plants cooling themselves. This increase in humidity is becoming more pronounced due to climate change and the expansion of industrial agriculture.
Warmer temperatures and nights, along with increased moisture in the atmosphere, are all contributing factors. The changing climate has allowed for the planting of corn further north and an overall increase in corn production in the United States.
