An Almanac of Extreme Weather

THE news from this Midwestern farm is not good. The past four years of heavy rains and flash flooding here in southern Minnesota have left me worried about the future of agriculture in America’s grain belt. For some time computer models of climate change have been predicting just these kinds of weather patterns, but seeing them unfold on our farm has been harrowing nonetheless.

My family and I produce vegetables, hay and grain on 250 acres in one of the richest agricultural areas in the world. While our farm is not large by modern standards, its roots are deep in this region; my great-grandfather homesteaded about 80 miles from here in the late 1800s.

He passed on a keen sensitivity to climate. His memoirs, self-published in the wake of the Dust Bowl of the 1930s, describe tornadoes, droughts and other extreme weather. But even he would be surprised by the erratic weather we have experienced in the last decade.

In August 2007, a series of storms produced a breathtaking 23 inches of rain in 36 hours. The flooding that followed essentially erased our farm from the map.
