White roofs cool the earth

If you want to slow down climate change and thinking of a roof paint job, choose the color white. Researchers concluded that painting roofs white increases albedo, the amount of light reflected from the earth’s surface back to space. In effect, the heat on the planet is reduced.

This report reminds me of Peru, where stones in Chalon Sombrero are being painted white to restore an extinct glacier.

Should we stop installing solar panels or tending the green gardens on our roofs, and switch to this cheaper alternative to cool the earth’s surface? One thing is for sure: if there were a worldwide contest for the highest albedo, Santorini would win.
