Subject: Corn Belt May_Jul climate anomalies



Centre county Pennsylvania, USA
NOAA publishes corn belt growing season climate anomaly history here:

https://www.ncdc.noaa.gov/cag/regional/time-series/261/tavg/2/6/1895...

Attached screen snap show the most recent 59 years of NOAA data for May_Jul and it's linear trend. It shows that average temperature has been trending up 0.021 degrees F/year (2.1 degrees F/100 years) and and average rainfall has been trending up 0.034 inches/year (3.4 inches/100 years).

The NOAA data is showing that US corn belt growing season average rainfall has been increasing faster than growing season average temperature. In other words, we need to grow corn in a much wetter growing season than our grandpa faced. That could explain our switch to 24+ row planters and 1000+ acre farms from grandpa's 4 row planters and 100 acre farms.

edit: corrected errors in linear trends.
