As Wednesday’s rush hour dies down on Interstate 70, Scott Campbell is merging onto the highway.

“Off like a herd of turtles,” he says.

Campbell is with Missouri’s Department of Transportation and he’s spending the night here with the maintenance team to repaint the yellow stripe in the fast lane. The caravan of trucks, with mounted signs, flashing arrows and bright lights, spreads out for more than a mile creeping along at 10 miles per hour. Even all these emblazoned alerts didn’t protect Campbell when was struck by a pickup on the job two weeks ago.

Farmers can expect more challenges, thanks to climate change. That’s according to a recent report released by the White House.

Iowa State University professor Gene Takle co-authored the chapter on agriculture in the 2014 National Climate Assessment. He says expected changes in humidity, precipitation and temperature may produce more extreme weather events.

“We need to be thinking forward as to the kinds of adaptation strategies that we need to adopt while at the same time we are looking for measures to mitigate the underlying cause of climate change,” Takle says.
