On this date in 1953, it was an unbelievable 101 degrees at Indianola, Iowa. September days over 100 degrees used to be fairly common there, but they haven’t had one in over 60 years.
For the entire year, the frequency of 100 degree days has also plummeted.
Prior to 1960, one hundred degree days in Iowa were fairly common, but they almost never happen anymore.
This drop in temperature after the 1950’s was well understood at the time, but criminals in the US government have since erased it.
NASA now shows current temperatures much hotter than the 1950’s, which has no basis in reality.
An entire field of science is based around massively fraudulent data from NASA, NOAA and CRU.
