Keith Cherkauer, an assistant professor of agricultural and biological engineering, ran simulation models that show Indiana, Illinois, Wisconsin and Michigan could see as much as 28 percent more precipitation by the year 2070, with much of that coming in the winter and spring. His projections also show drier summer and fall seasons.
"This was already a difficult spring to plant because of how wet it was. If you were to add another inch or so of rain to that, it would be a problem," said Cherkauer, whose findings were published in the early online version of the Journal of Great Lakes Research. "It could make it difficult to get into fields. There's also a potential for more flooding."
Cherkauer used three different scenarios based on the amount of carbon that could be emitted into the atmosphere in the coming decades. Carbon calculations were based on assumptions including population, technological advancements, the economy and other factors.

Kann dies aus eigener Erfahrung bestätigen. War öfters in Afrika unterwegs und meist das Problem ums Wasser.
