That’s why we need passive daytime radiative cooling. In theory, it could completely eliminate the urban heat island, but it still seems to be mostly at the pilot project stage so far. I did read somewhere that you can DIY with some packaging tape (which somehow has the right properties?) over a reflective backing. Maybe I’ll experiment a bit this summer.
I’m planning on making some panels to help cool my garden in an attempt to help plants survive extreme heat and sun by shooting some of that heat into space! The combination of partial shading with cooling mass vs heating mass should help a bit. People think it doesn’t work, but I’d imagine growing a garden on a asphalt blacktop vs white cement would make a few degrees difference. This technology does the same thing, it just pushes the boundaries further to cool below atmospheric temperature.
You’re the first person I’ve seen bring this up, not sure why it’s not more popular, just new I guess. Also, usually when I bring it up people say it’s’ bad because it will encourage more fossil fuel growth and they totally miss the point.

You totally can.
