“Corn sweat” is pushing the heat index in Iowa above 110 degrees
What makes the weather? Is it just clouds and storm systems? Huge domes of air pressure, trapping heat over sweltering cities? It’s all that, and corn sweat, the Washington Post reports. Every summer, the water that evaporates from hot crops enters the atmosphere and creates unbearable, Florida-like humidity in some of the country’s least-tropical locations—like Iowa, where there’s over 13 million acres of corn. If a single acre can sweat about a swimming pool’s worth of water every week—well, you do the math. Man-made climate change, indeed.
