Heat Indices Above 105 Degrees for 80 Million Americans This Weekend (axios.com) 135

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 health... Heat 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."

  • By weird its ten to fifteen degrees cooler than normal. Of course the humidity is hovering around 90 percent so its not exactly comfortable outside if you are working.

      Here in Arizona, it got so hot on my back porch the other day that the wireless on my remote temperature sensor stopped working. The last temperature reading I got from it was 123F, after that, who knows how hot it got. Really dumb that the wireless module goes out of spec at such a low high temperature.

      FYI, ambient outside temperatures weren't likely so hot in general, as my back porch (where the sensor is located) is artificially heated by the output of my house's A/C. Official high this year is only 115F so far, which is nothing considering we top out at 122F in a really hot summer in AZ.

      South where?

      I'm in Texas and if you go to almanac.com it's literally 5 degrees hotter lows, median daily temperature, and highs for this time of year than it was during the entire 1980s. It's also warmer than the 90s and the 2000's but not by as much--- because they were warmer than the 80s.

      And no, I didn't ignore the 70s- I just made an arbitrary cutoff before I started looking because it was 86 data points as it was. And I already knew it as even cooler than the 80s in the 1950s.

        OK. Weather is not climate. Climate gives you a set of probabilities of events happening and weather is the events that happen. This is weather. But it's weather that was made a lot more likely because of the way the probabilities of climate shifted.

      Nah, they're just geo-engineering extra heat in the atmosphere to keep the sheeple believing in global warming so they'll spend more money on combating it. It's a conspiracy concocted by corporations, aliens and probably the Energizer Bunny. I don't know why the bunny is involved though...perhaps he gets free power from the solar panels or something...

    Seems like it should be higher...

    • The problem with solar power is that it needs on one hand a lot of sunshine but on the other hand it doesn't handle heat terribly well.

      So... the best place to put it would probably be the poles. Just ship it halfway around the globe twice a year.

        Another advantage (besides the 2x to 4x power/area boost and theoretical efficiency limit over 90%) for the optical rectenna type solar panels now under development: If they use geometric rather than semiconductor diodes they should be essentially immune to high temperature voltage droop. (At least until the environment is getting warm enough to glow.)

  • God is testing the faith of the MAGA. But not even Jesus can convince those dummies. These same fools who couldn't understand why they had to take the vaccine if all it did was protect grandma and a few weak and sickly people. With this heat wave they'll blast their AC and keep pumping CO2 gas into the air, what's the worst that could happen? After all, God intervenes to protect the Earth the same way he protected the 90 million who died horribly in WW2. The same way he protected the people tortured by Unit

    The hilarious thing is that by the time this story broke, the weather made a drastic change and this weekend and the following week will be significantly cooler than the previous week.
