I've been following Tony Heller for years and watching ... as Toto pulls back the curtain ....

Not only do they change where they start, they leave out years, as 1923 (the hottest year in the U.S. on record) totally disappears from NASA's calculations. Look at the cooling trend, shown by NASA's own data and THEIR charts, in 1999. Take a look at their 2014, covering the same period ... (hottest decade was the thirties), they've actually dropped the daily high, and average, of each year from the 1930s, by 5 to 10 degrees.

And, think about this .... there are people actually SO stupid as to believe NASA's lies.
