 Hell on Earth: With an average temperature of 107.39 degrees in July, Death Valley set the record for hottest month at a single location in U.S. history. 
 
 Keep in mind that that number is an average of all the high and low temperatures. The average daily high temperature was an unbearable 119.6 degrees. 
 
 “It should be noted that this is the hottest average monthly temperature ever measured in the U.S. or, for that matter, anywhere in the Western Hemisphere,” Weather Underground weather historian Christopher Burt told the Capital Weather Gang. 
 
 It was not a world record, however: Climatologist Brian Brettschneider said the world record warm month was in August 2015, when King Khaled, Saudi Arabia, measured an average temperature of 107.44 degrees.

 And nights were no bargain in Death Valley last month: The temperature didn't drop below 89 degrees the entire month of July, the National Weather Service said. Three days, the overnight low temperature was over 100 degrees. 
 
 July's hottest day was the 7th, when Death Valley hit 127 degrees. It was also 127 on two June days. 
 
 Death Valley is a national park with no permanent residents except for a few park service staff and rangers. It is the hottest, driest and lowest of all U.S. national parks. 
 
 Several other cities set record warm months in the West, as did Miami, the weather service said.

 (This post, originally posted on June 29, was updated on July 3.) 
 
 A city in southwest Iran posted the country’s hottest temperature ever recorded Thursday afternoon, and came very close to the world record for the most extreme high temperature. 
 
 Etienne Kapikian, a forecaster at French meteorological agency MeteoFrance, posted to Twitter that the city of Ahvaz soared to “53.7°C” (128.7 degrees Fahrenheit). Kapikian said the temperature is a “new absolute national record of reliable Iranian heat” and that it was the hottest temperature ever recorded in June over mainland Asia. Iran’s previous hottest temperature was 127.4. 
 
 This reading, if verified, fell just short of the hottest temperature ever measured on Earth in modern times of 129.2 degrees (54.0 Celsius). 
 
 Christopher Burt, a weather historian for Weather Underground, has exhaustively analyzed world temperature extremes and determined the 129.2 degree readings posted in Mitribah, Kuwait on July 21, 2016, and Death Valley, Calif., on June 30, 2013, are the hottest credible temperature measurements that exist in modern records. 
 
 Officially, Death Valley set the record for the hottest temperature ever recorded on Earth on July 10, 1913, soaring to 134 degrees (57 Celsius). But Burt posted a devastating critique of that measurement in October 2016, concluding it was “essentially not possible from a meteorological perspective,” and that the weather observer committed errors. 
 
 For the 128.7 degree-reading Ahvaz posted on Weather Underground to stand and rank among the highest observed world temperatures, it will require review by the World Meteorological Organization. 
 
 The scorching temperature reading was brought about by a dome of heat centered over the Middle East. 
 
 The excessively hot air over Ahvaz, a city of 1.1 million people, felt even more stifling due to high humidity. As the temperature climbed into the high 120s, the dew point, a measure of humidity, peaked in the low 70s; a high level for the desert location (due to moist air flow from the Persian Gulf, to the south). The heat index — a measure of how hot it feels factoring in the humidity — exceeded 140 degrees. This combination of heat and humidity was so extreme that it was beyond levels the heat index was designed to compute. 
 
 In the Persian Gulf city of Jask, Iran, about 800 miles southeast of Ahvaz, the humidity was even more suffocating. The dew point on Wednesday morning hit 91.4 degrees. Dew points above 90 are quite rare. The highest dew point ever measured on Earth is 95 degrees (35 Celsius), set at Dhahran, Saudi Arabia, on July 8, 2003. 
 
 Thursday marked the second straight day of record heat in Ahvaz. On Wednesday, it hit 127.2 degrees (52.9 Celsius), breaking the record for Iran’s hottest June temperature, only to be exceeded the next day. 
 
 These Iranian temperature extremes come just a month after several locations in the Middle East recorded their hottest May temperatures during another exceptional heat wave. 
 
 On May 28, the western Pakistani town of Turbat hit 128.3 degrees (53.5 Celsius), tying the all-time highest temperature in that country and the world record temperature for May, according to Weather Underground meteorologist Jeff Masters. 
 
 At the same time Masters reported that at the military base of Konarak in eastern Iran, the temperature reached 127 degrees, “destroying the record of the highest temperature ever recorded in May in Iran (50.5°C in Bostan in May 1999).” 
 
 All of these record-breaking temperatures in recent years, including Thursday’s reading in Ahvaz as well as those set in Kuwait and Death Valley in 2016 and 2013, represent temperature extremes consistent with what climate scientists expect to see in a warming world. 
 
 The National Academy of Sciences published a report in 2016 that said worsening heat waves are among the weather events that can be most easily connected to human-caused climate change. 
 
 A study published in the journal Nature Climate Change in 2015 cautioned that by the end of the century, due to climate change, temperatures in the Middle East may become too hot for human survival. 
 
 Correction, July 3, 2017: The original version of this post said Ahvaz may have tied the world-record high temperature of 129.2 degrees based on an observation posted on the Weather Underground website. It turns out Weather Underground rounds temperatures in Celsius up to the nearest degree, which artificially increased the actual high of 53.7 Celsius (128.7 Fahrenheit) to 54 degrees (129.2 Fahrenheit). This post has been corrected to note that real high was 128.7 degrees (53.7 Celsius) – which is 0.5 degrees lower than the highest observed world temperature in modern times of 129.2 degrees.
– It's probably been a hot summer where you are, but nothing like this: California's Death Valley registered an average temperature of 107.4 degrees for the month of July, per the National Weather Service. The previous record, set in 1917, was 107.2 degrees. It's not only a record for Death Valley: "It should be noted that this is the hottest average monthly temperature ever measured in the US, or, for that matter, anywhere in the Western Hemisphere," a climatologist tells the Washington Post. If 107.4 doesn't seem insanely high, keep in mind that was the average temperature of both days and nights, notes the Los Angeles Times. During the day, it typically got up to 120 degrees before cooling down to about 95 at night. The hottest day came on July 7, which saw a temperature of 127. Fortunately, few people were affected: As USA Today notes, Death Valley is a national park with no permanent residents save for park rangers.
