All hot and sweaty this summer? It could be the corn.
Climatologists are building evidence that crops, particularly corn, are driving up dew points as they put water into the atmosphere through evaporation. They also may make corn-growing areas cooler and alter rain patterns....In some ways, researchers are taking a second look at a 19th century adage — "rain follows the plow." Popularized by Charles Dana Wilber in an 1881 book touting the agricultural promise of Nebraska, the phrase supported a grand notion that the western Great Plains, which in the early 19th century had been labeled the "Great American Desert," could be transformed into a garden if people would expose its moist soil to the atmosphere.
