Below are the high temperature records for July 13, at all Oklahoma USHCN stations which were operating in both 1930 and 2011. The year 1954 set the most records, and only one station managed to tie a record since the turn of the century. All but two of these records were set below 350 ppm CO2.
Our friends have been lying about evidence linking US heatwaves to CO2. The evidence simply does not exist. NCDC claims that July 2011 in Oklahoma was the hottest month in US history, but not a single record was set in Oklahoma on July 13, 2011.
