In Table 1, below, we list the all-time record daily maximum temperature observed
in each of the 52 entries (as compiled by the SCEC) and the date and location where
it was recorded. Notice that the vast majority of the all-time records were set more
than half a century ago and that there are exceedingly few records set within the
past few decades. This is not the picture that you would expect if global warming
from greenhouse gas emissions were the dominant forcing of the characteristics of
our daily weather. Instead, natural variability is still holding a strong hand.

In Table 2, we’ve compiled the top five years when the most records were set. When
multiple years tie for the high, each individual year gets a fraction of a “record”.
So, for example, 1954 and 1933 each get a half of a record for Colorado.
