Prior to government data tampering, 1934 was the hottest year on record in the US. This was unacceptable to climate scientists who depend on global warming junk science funding, so they changed the data.
1934 was just behind 1936 in frequency of hot days.
May-August 1934 was spectacularly hot across the US.
And the US was in record drought.
So NASA and NOAA had to make the heat disappear.
