I say it's total BS.

I used to hang out at a beach near the yacht harbor next to the Ilikai
hotel in Waikiki.

For years and years, the parking lot was just plain old dirt - light
brown, somewhat dusty.

Then somebody got the bright idea of paving the parking lot with
blacktop.

It made a huge difference. The parking lot area and adjacent beach went
from being comfortable to being almost unbearably hot without a strong
breeze to mitigate it.

So, unencumbered by any other knowledge, my money's on the white
roofs...

There is also a big difference in artificial grass vs natural.

Driving around the city suburbs, it's often a relief to drive through a
heavy tree area. Seems 15-20 degrees cooler.
