How is this solution a psychological crutch? If there is evidence that painting roofs white will help cool off cities and reduce your a/c usage by 15%, why not do it?
The analogy you provided is not applicable.
- ars 17y ago"If there is evidence that painting roofs white will help cool off cities and reduce your a/c usage by 15%, why not do it?" Is there actually evidence for this? In the real world, not just some calculations? Various people have pointed out flaws such as: it won't stay white. In the winter it makes things worse, and depending on where you live the net is no good. One reason not to do it is that it costs more than it saves. And in the places where it's really bad, like Tuscon, they put white rocks on the roof, so I bet that anyplace where it's worth it - it's already being done!

The entire video is fascinating if you've got 2c of coffee in you.
