Pavement, especially blacktop, is just the worst.
I wonder why in the Midwest they tend to pave their city roads in cement, not blacktop. I came to the conclusion that maybe it's because the snow and cold make blacktop get potholes more easily? Cement deals with the cold better? But I don't know for sure.
But either of them, pavement or blacktop, are just awful in the desert. There are a few trees, very few, that can survive in such heat. One if the African Fern Tree and once they grow tall, they are quite good shade providers.

Palm trees are OK, but the huge mistake cities always make is that they plant them far apart, often as lone individuals meant to be more decorative than shade-producing. But in the wild, palm trees grow close together and that way they can actually provide shade. They are a pain in the rear to trim though. City has to figure that cost in.
But Phoenix, yeah, I'd put it on my list of Cities to Fix First for the heat of climate change.
That is the problem with Boom Towns. Everybody is busy counting money brought by the newcomers but they never sit down and actually PLAN for all the negative repercussions. The


blinds them.
The Jacaranda is another great shade tree that can survive in Phoenix.

These city & county leaders need to turn into tree-huggers STAT.
