According to NCDC,
- 1933 was the hottest June on record in the US.
- 1936 was the hottest July on record in the US.
- 1936 was the hottest summer on record in the US
- The summers of 1930-1939 averaged the hottest of any decade since the start of the database in 1895.
Even with all the cheating, bumping post 2000 temperature upwards by more than half a degree, and knocking a tenth of a degree off the 1930s – the 1930s still stands out as the hottest summers.
Next time James Hansen claims that the recent warm spring is proof of global warming, please remind him that he has no idea what he is talking about, and is hurting lot of people with his incompetence.
