There’s little to no evidence man-made global warming is hurting U.S. crop yields in corn belt states, according to a climate scientist who’s spent years consulting on the issue.
In fact, it’s unclear the U.S. corn belt has gone through any statistically significant warming since 1960 despite climate model predictions the region would warm about 1.5 degrees Celsius over that period.
“That plot alone should tell you that something is wrong with the climate models,” according to Dr. Roy Spencer, a climate scientist at the University of Alabama in Huntsville. Spencer runs a satellite-based temperature data set along with climate scientist Dr. John Christy.
“It’s not even obvious a statistically significant warming has occurred, let alone attribute it to a cause, given all of the adjustments (or lack of proper adjustments) that have been made to the surface thermometer data over the years,” Spencer recently wrote in a blog post entitled “Global Warming Be Damned: Record Corn, Soybeans, Wheat.”
