We moved to Tempe back around June 1987 and I had the summer off while the better half went to work. We moved from Gainesville, FL. One of us was raised in S. FL and the other GA. In Gainesville, we lived through the summers with an apartment and cars w/o AC. I worked in exterior renovation during one summer in Atlanta when it reached 100F regularly, and the summer after high school in S. FL installing attic HVAC metal ducts in new construction. So we thought we knew heat.

So I'm in the apartment in June and the complex has got a pool so like I'd always done I put the swimsuit on, grabbed a towel, and strode barefoot across the parking lot in the direction of the pool. It was probably 101F, nice day for June. About halfway across the lot I realized I was burning my (tough) feet. I'm a practical person and noticed the white stripes in the lot and ran to one. YUP! At least 20F cooler. Ever since I've wondered why you couldn't do something like that white paint for all the asphalt and concrete. Turns out you can. Hooray! I'm in Tucson now (it's currently 106F/22%). I'm out at 5AM for a bike ride many days and the lows have been steadily climbing over the past decades. Was 84F this morning, the lows increasing every day this week, YUK. When I ride out to the actual desert it gets noticeably cooler, maybe 5F. I want them to take this stuff and just coat the entire Tucson metro area with it.

I just simply don't understand why so many people live in Pheonix given the issues with heat and lack of water sources.

Meanwhile CA just passed zone zero regulations to defoliate the suburbs and increase the heat island effect while destroying wildlife habitats because we'd rather run scared than use better technology to fight wildfire risk...

Anyway, back to the story, I just saw this the other day: https://www.autonocion.com/us/target-mirror-panels-supermark...

Sigh. Fake pictures, plus internal links to the India Times.

The city of Phoenix has some web pages on this. There are pictures of the real coating, pictures of it being sprayed on, and links to technical studies. Phoenix has been doing this since 2021, gradually spraying more streets. It looks like grey paint but has asphalt in it.

Good idea, AI slop article.

I was in Tempe/Phoenix region during the peak of summer (August I remember). It was 115°F+ everyday. Even after dinner, when I wanted to stroll around outside the mall near ASU, it was 90°F. It was insane how hot it was. I’ve lived in Houston and the heat was not even that high. But Phoenix has almost zero humidity in the summer which makes the heat a lot more bearable comparing to the sauna in Houston. Anyway, would not go there during summer again!

Why not use concrete instead of asphalt? This person registered a 20 degree difference between the concrete sidewalk and asphalt road.

The equivalent of 6.6°C according to google.

Plants would lower it even more

>but pedestrians faced higher radiant heat

As would vehicles.

Phoenix is the hottest city I've ever visited. The people were great, but I struggle to imagine why anyone would want to live there, let alone build semiconductor factories in an area already short on water supply.

Has Phoenix tried less Asphalt?

Does anyone have any real photos of the reflective asphalt?

Phoenix Arizona is a fucking hellscape unfit for human habitation.
