Iowa City — NEGOTIATORS en route to the United Nations conference on climate change in Paris, scheduled to begin later this month, should take a detour on rural roads here in Johnson County. A new climate narrative is emerging among farmers in the American heartland that transcends a lot of the old story lines of denial and cynicism, and offers an updated tale of climate hope.

Recent polls show that 60 percent of Iowans, now facing flooding and erosion, believe global warming is happening. From Winneshiek County to Washington County, you can count more solar panels on barns than on urban roofs or in suburban parking lots. The state’s first major solar farm is not in an urban area like Des Moines or Iowa City, but in rural Frytown, initiated by the Farmers Electric Cooperative.

In the meantime, any lingering traces of cynicism will vanish in the town of Crawfordsville, where children in the Waco school district will eventually turn on computers and study under lights powered 90 percent by solar energy. Inspired by local farmers, who now use solar energy to help power some of their operations, the district’s move to solar energy will not only cut carbon emissions but also result in enough savings to keep open the town’s once financially threatened school doors.

Wind turbines now line cornfields across the state, providing nearly 30 percent of Iowa’s electricity production. With some $10 billion invested in wind energy and manufacturing in Iowa, Republicans and Democrats alike recognize the benefits of green jobs.
