From 2012 but worth a look back-----Dear NOAA and Seth, which 1930's were you comparing to when you say July 2012 is the record warmest? | Watts Up With That?

Dear NOAA and Seth, which 1930's were you comparing to when you say July 2012 is the record warmest? | Watts Up With That?
"The press release is out, and the usual serial bloviators are rushing to trumpet the news. July 2012 was the hottest ever on record! 
“Yikes! We’re gonna roast! Global Warming!” they wail on Twitter and blogs. 
The driver of this is AP’s Seth Borenstein, who never met a hot story he didn’t like.

Of course the first thing I do when I see these sorts of things is go look at the data. 
It tells a far more interesting and credible story. 
Here’s some graphs NCDC and Seth won’t ever put in a press release or AP story:
Now let’s compare to July 1936:
A few things stand out right away.
1. Due to regional weather pattern variability, one state in 1936 had below normal temperatures, Texas. Take the 1936 Texas below normal temperature out of the mix and there goes your 0.2F record making difference with July 2012.
2. Many states had warmer temperatures in 1936 than 2012.  
Here’s a table, all numbers in degrees Fahrenheit..."
