There are 901 USHCN stations which were operating during both 1930 and 2011. Out of those stations, eighty-nine percent set their all time July 14 maximum temperature record with CO2 below 350 ppm.
Thirty-eight percent (347) set their all time July 14 record during the 1930s and eighteen percent (162) set their all-time July 14 record during the 1950s.
Only three stations have set their all time July 14 record during the current decade.
There is no basis for attributing US heat waves to CO2. How can NOAA lie about this?
