Unless we contain carbon, our food supply will be under threat. By 2050, US corn yields could decline by 30%

I know a stiff wind. They call this place Storm Lake, after all. But until recently most Iowans had never heard of a “derecho”. They have now. Last Monday, a derecho tore 770 miles from Nebraska to Indiana and left a path of destruction up to 50 miles wide over 10m acres of prime cropland. It blew 113 miles per hour at the Quad Cities on the Mississippi River.
