      Phoenix exists as a monument to human hubris. You aren’t actually supposed to live there. /s

      Once we can vote out the conservative lunatics, we can make solar and wind farms in the uninhabited desert. It’s the conservative retards in Phoenix with the grass lawns and all the water wasting bullshit.

      Down here in left leaning Tucson, the vast majority of people do not have water wasting bullshit property fauna. Palm Springs is only about 5 hours away and that’s what they’re doing and they seem to be doing well with it.

    Anything but cutting off burning oil. I mean it’s a step towards short term comfort but it’ll keep getting hotter as we have polluted our air and have not stopped.

      Even if we got to Net Zero tomorrow, the world is going to continue to warm, and we have to develop and deploy adaptive measures.

      We can both support the ending of fossil fuel AND celebrate adjustments like this.

    The cool pavement technique is neither a gimmick nor a failure. It reduces the surface and sub-surface temperatures, which helps the road last longer. However, if the goal is pedestrian comfort, cities may need to consider shade, tree cover, and where these coatings are used, not just the color of the coating.

    Well, since pedestrians are like the 3rd or 4th concern when it comes to roads, it sounds like white and silver roads are in our future. — Cynical Snarky Online Comment.

    Am I thinking wrong?

    If you walk down the street and there is reflective coating under you, don’t you now get hit by sunbeams from top and bottom?

      it’s in the article.

      Also, Phoenix uses mostly white concrete for roads, it’s too hot for asphalt.

      Yes, but most of the time, on most of the street, there isn’t a person or other object absorbing sunlight from both directions. So the vast majority of the heat that would’ve been absorbed into some kind of temperature increase in the road itself (and surrounding air and objects) gets rejected back into the sky/space, at the cost of a little bit more sunlight being absorbed directly by the cars and people who happen to be walking by.

      47°C in Phoenix this week. You’re going to die outside regardless of how they paint the asphalt.

          That’s still survivable below 40% humidity. We can deal with a wet bulb temperature of 35°C or below. At 47°C that works out at around 40% humidity.

          I’ll quote the relevant passages for you. It describes the results from two different studies.

          Study #1:

          The research found that mean radiant temperature, a measure of the thermal radiation absorbed by the body outdoors, rose by an average of 5.5°F on the coated streets.

          Study #2:

          It noted […] mean radiant temperature over the [coated] pavement rose about 4°C (7.2°F) at midday

      Absolutely. You would get double the dose, like skiing in a bathing suit. I’ve seen people come off the hill just fried because it’s cool enough they don’t notice getting burned to a crisp by the snow reflection.

        Yep. Got a good sunburn when camping in the mountains for the first time in Arapaho National Forest. Snow 2 feet deep on the ground under the trees, but the UV up that high is pretty brutal and got my arms and legs pretty good. Thankfully was wearing a hat with a nice wide brim all the way around so my face, neck, and ears were unscathed. Definitely a learning experience.

      I think the argument is that being hit by sunbeams from both sides causes less heat exposure than by the sun from above and asphalt that gets beat on by the sun and radiates heat back up.

      I think I’ve seen other places use infrared reflective paint only to avoid excess heat and get similar results.
