> For urban heat zones, AC seems to be criticized in isolation. There's never a mention of a lack of tree canopy in vast parts of the city, or that reflective pavements and green roofs are nonexistent.

I totally agree on the importance of trees, reflective pavements, green roofs, etc.

However, pretty much everybody who is critical of AC would also support the things you've listed. Is your complaint that people do not talk enough about it? That's not really my experience.

I have the feeling that widespread use of AC would make it even harder to make these changes. At the very least, these things must go hand in hand.
