158ºF or 70ºC in Southern Iran last Sunday

But percentages in the stock market seem to be more important to efficiently combat climate change.

Heat index or apparent temperature is not the same as actual temperature. Would still suck but at least you aren't being pasteurized.

Jesus Christ, 158 F heat index is so far out of bounds on that scale it's insane. What's after "Extreme Danger"? "People will die"? "Being outside is suicide"?

A [wet-bulb temperature] reading of 35 °C (95 °F) – equivalent to a heat index of 71 °C (160 °F) – is considered the theoretical human survivability limit for up to six hours of exposure.

Ah phew. It’s just the absolute limit for human survivability 😮‍💨

It's when it feels really hot and you look at the thermometer and think, "wow is that it? I better arbitrarily add a few more degrees so people know it's really hot"

Down voted. Please repost with a link to the source. We're better than this.

A heat index is not an actual temperature reading. This is disingenuous and people whom don't want to believe in things like climate change will latch on to and discredit people for things like this.

People who.

But the point is we'll taken. It seems like a really misleading headline. That doesn't help things at all.

If you're gonna correct someone else's grammar, you better make sure your own grammar is squeaky clean first, lol.

Would like to see the option to add "Misleading Title" to articles, similar to what used to exist on "R". Not enough people downvote misleading stuff.

probably faulty sensor, there's no way the temp is 15 degrees higher than the current highest temperature ever measured

It would be amazing if some how the heat would cut off access to the persian gulf, it would definitely push the world to think of alternative energy

Choking off that straight would absolutely grind to a halt the economic engines of every asian major power faster than they could find a solution to exporting the hundreds of millions barrels a day though that hostile environment.

The real temperature are 58ºC, but relevant is the index, that is, how we percive the temperature. With a dry air you can support more than 70º (eg in a Sauna), but with high air humidity, which evite the evaporation cooling by your sweat, even 50ºC result lethal in a short time, rising corporal temperature over 43ºC. Because of this, it's the index which is the relevant value, not the one shown by the thermometer.

Yep.

100f+ degree weather with zero humidity? Sweat evaporates so quickly that with a fan on you or a breeze you can actually feel briefly chilled at times.

I know. There's also this:

https://en.wikipedia.org/wiki/Wet-bulb_temperature

But mentioning the actual temperature is less misleading.

With a dry air you can support more than 70º (eg in a Sauna), but with high air humidity, which evite the evaporation cooling by your sweat, even 50ºC result lethal in a short time,

Over 90C dry, 50C wet, 10-15 minutes. Longer/hotter if you take dips in cold water to cool down or if you're Finnish. They sometimes go over 100C, they're used to it.

Is hot but Washington Post article says the temperature in recent weeks has got as high as 51C and all time max is 54C. Where are you getting 58C from?

The title is a little clickbait-y: Heat Index is different from Temperature and not everyone knows that.
While it's still bad, it sensationalizes the matter and this can be used against you from people that have a different opinion on the subject.
