USHCN Temperature Record of the Week: Galva, IL

To bolster our claim that "There Has Been Little Net Global Warming Over the Past 70 Years," each week we highlight the temperature record of one of the 1221 U.S. Historical Climatology Network (USHCN) stations from 1930-2005.

This issue's temperature record of the week is from Galva, IL.  During the period of most significant greenhouse gas buildup over the past century, i.e., 1930 and onward, Galva's mean annual temperature has cooled by 0.32 degrees Fahrenheit.  Not much global warming here!
