An anonymous reader shared this report from Axios:

Over 20% of the U.S.’ population — 80 million people — are expected to face an air temperature or heat index above 105 degrees Fahrenheit this weekend as a record-breaking heat wave persists over most of the South, the National Weather Service (NWS) warns…

The extreme temperatures, which have been exacerbated by human-caused climate change, will come after several days of excessive heat and will be an immediate risk to public healthHeat index is what the temperature feels like to the human body when relative humidity is combined with the air temperature, and indices 103 degreesF or above can lead to dangerous heat disorders.

“Dozens” of temperature records could break across the Southern U.S., including overnight highs, the NWS said… About 115 million people in over a dozen states from California to Florida were under heat alerts on Thursday morning… The threatening heat is forecast to continue over the Southwest through “at least” July 28 and may expand into other parts of the country…

Global temperatures are hitting unprecedented highs, too, this year amid climate change and global warming. Elevated temperatures are also contributing to Canada’s worst fire season on record, in which at least 27.1 million acres have burned across the country so far.


On Wednesday the city of Phoenix, Arizona — population 1.6 million — “experienced its 20th straight day with a temperature of over 110 degreesF,” the article points out. And meanwhile Austin Texas (population 960,000) “saw its 10th straight day of temperatures at or above 105 degreesF for the first time in recorded history.”

The National Weather Service’s advice? “Take the heat seriously and avoid extended time outdoors.”

The best things in life are for a fee.
