NBC Meteorologist Bill Karins said on Friday , “We’ve never really seen a heat wave like this in the month of June.”
How hot is it? It’s so hot that all-time records are being set in June: “Nashville has reached its hottest temperature on record…109 degrees at 314 pm. The previous all time record was 107 from July 27th and 28th of 1952.”
How hot is it? It is so hot that NBC Washington’s Chief Meteorologist, Doug Kammerer, explained on air “If we did not have global warming, we wouldn’t see this.”
As Climate Central explains in its post, “Scorching June Heat Wave Puts 50 Million in U.S. on Alert”:
“During the June 22-to-28 period, there were 2,132 warm temperature records set or tied in the U.S., compared to 486 cold temperature records. This includes 267 monthly warm temperature records, and 54 all-time warm temperature records.
"For the year-to-date, warm temperature records have been outpacing cold temperature records by about 7-to-1.
"In a long-term trend that demonstrates the effects of a warming climate, daily record-high temperatures have recently been outpacing daily record-lows by an average of 2-to-1, and this imbalance is expected to grow as the climate continues to warm.
"According to a 2009 study, if the climate were not warming, this ratio would be expected to be even. Other studies have shown that climate change increases the odds of extreme heat events and may make them warmer and longer lasting.
"All-time records set Thursday included several in Kansas, where Norton Dam recorded a high of 118°F, beating the old record of 113°F set just a few days earlier. Dodge City, Kan., set a daily high temperature record with a mark of 108°F. That came one day after that town recorded its all-time highest temperature of 112°F, breaking the old record of 110°F, which had been recorded just two days earlier, on June 26.”
Since the science of attributing extreme events to global warming is still emerging, scientists still disagree to what extent a specific event like this heat wave is driven by global warming. But two of the leading experts explain at RealClimate why even small shifts in average temperature mean “the probability for ‘outlandish’ heat records increases greatly due to global warming.” Furthermore, “the more outlandish a record is, the more would we suspect that non-linear feedbacks are at play – which could increase their likelihood even more.”

July was so hot “that just by plotting the location of each daily heat record that was broken, a nearly complete image of the contiguous United States is visible,” reports NOAA. “Almost 9,000 daily records were broken or tied last month, including 2,755 highest maximum temperatures and 6,171 highest minimum temperatures (i.e., nighttime records).” “Some cities reached daily high temperatures 19 out of the 31 days in the month.” The data is incomplete, as they “only include weather stations with real-time electronic reporting, which accounts for about two-thirds of the locations.”
