Corn yields are up, but are likely to go down
For more than 40 years, U.S. corn yields have seen increases in the time period from 1974 to 2019.
Certain climate trends, like warmer temperatures and more rain, have helped the U.S. crop, according to data analytics firm, Verisk, but those same trends could also hurt the crop moving forward. Verisk says if plant genetics go unchanged, there will be more weather variability and bad years.
It is predicted we will see more extreme heat and cold moving forward, and that is the primary reason for crop insurance losses. Verisk says because of that, investors are interested in adding climate change to environmental, social, and governance analysis.
