US Monocultures Adding To Heat/Humidity - One Acre Of Corn - 3-4,000 Gallons Of Water Vapor During Hot Weather

You won’t believe your ears, but corn is making the extreme heat the US midwest is battling feel more intense, according to experts. The moisture – or “sweat” – that corn and other crops release in high temperatures is contributing to the humidity in the air in the midwest US, where 55 million people have been under alerts for extreme heat in recent days. The increase in moisture pushes up dew points, making it harder for water vapor to condensate – and for it to feel cooler.

Exacerbating the situation is the fact that the US is the “largest producer, consumer, and exporter of corn in the world”, as well as ethanol, which the country primarily makes from corn kernel starch, according to the US Department of Agriculture. And two states in the grips of the heatwave – Iowa and Illinois – are responsible for a third of US-produced corn.

That has left residents of those states, along with other prolific corn-producing neighbors, feeling even warmer as they grapple with scorching temperatures forecasted to reach 105F (41C) to 115F (46C). “It is the plants reacting to that warmer weather. They also then need more moisture, so they’re uptaking more from stored-underground water and bringing that up to the atmosphere that we’re in,” Chris Clark, an agronomist at the University of Wisconsin-Madison told a local CBS news outlet.

One acre of corn, which is a little smaller than the size of an American football field, can can create 3,000 to 4,000 gallons of corn sweat, Clark said.

1. Yep.

As one who lives in the middle of a LOT of corn, you can see the corn transpiring as mist above the fields. You can't breathe water vapor, and as most of this corn is biofuel (we all know about how well that works), it is hard to breathe and there is no benefit from the corn as food.
