It's absolutely true though. I used to live in Kuala Lumpur, and there is one district called Cyberjaya where they removed all the trees. It was noticeably hotter than the surrounding districts from just that one change.

Such a what I would have thought innocuous change, but it made a massive difference in climate for that one area.

It's such a cheap and efficient way to cool down places as well, and seeing the climate catastrophe on our horizon it might be a great idea to get some shade requirements in building codes across the globe.
