Ok. That “streak” of consecutive months of more daily record highs than daily record lows for the U.S. is now up to 31 in the National Center for Environmental Information is up to 31. So what other trends in the June 2017 numbers can we spot?
When we start breaking down the numbers that trend of more daily high minimums (warm lows) followed by daily high maximums, then daily low maximums (cold highs) with daily record low minimum temperatures being the least number of reports holds for June:
2,461 DHMN 1,836 DHMX 953 DLMX 767 DLMN
Yep, the trend of nights warming faster than days, which is expounding upon in the link below, held for June.

This trend is holding true across the nation for 2017 and even across the planet (global counts in NCEI database through 6/30):
32,279 DHMN 26,431 DHMX 10,132 DLMX 7,725 DLMN
So after June at the halfway mark of 2017 we see the following stats that can be compared with the rest of the years for this decade:
The ratio of daily record highs to lows for the U.S. is less than the all-time record set in 2016. This is no surprise since the U.S. was highly affected by the warming from the last record El Nino of 2015/16, and the planet is now a hair cooler than it was last year.
These record counts are obviously proof of global warming and the tie-in to carbon pollution. At some point in between strong El Ninos I expect that “streak” to break. Perhaps after the next strong El Nino the next “streak” won’t end as the planet’s average temperature gets so warm that record cold temperatures become as rare as endangered species. Dangerous heat will increasingly become a threat, especially during the summers to come, and I’ll continue to report in that aspect of climate change for as long as I can type.

Good stuff. Unfortunately, a few typo-type errors that make the text a little confusing:
1) What’s DMMN? I think you meant DHMN. Obviously, important for acronyms (if not explained) to match the column headers.
2) Then you say “the trend of days warming faster than nights,” followed by a link that refers to nights warming faster than days.
Otherwise good, but just to be even clearer (for a general audience), I’d add a paragraph that explains the acronyms: “Here’s a numeric comparison: DHMN (record daily high minimum temperature), DHMX (record daily high maximum or “record high”), DLMX (record daily low maximum), and DLMN (record daily low minimum or “record low”)
