The "one study" I was referring to was in response to the previous commentor,,and this is the link they had.
I am just as skeptical as you are. The argument they seem to be making is that white roofs reflect heat back into the atmosphere instead of absorbing it, which leads to reduced cloud cover and rainfall. Their conclusion is that white roofs result in lower temperatures locally, but higher temperatures across larger regions.
They could potentially be on to something, but it's also possible that either they are mistaken or biased by the same money these corporations are throwing at legislatures.
But we also have a lot of data about how reduced ice coverage in places like Greenland is resulting in a positive feedback loop that increases temperatures in part because more light gets absorbed by the ground and less gets reflected back, which leads to more ice melting. If this one study is correct, I would expect to see much more stable temperatures and ice sheets in the poles than we see today and have seen historically.
