If we paint all our cities white, will we get more snow?

Some bright spark has found a way to make white paint extra reflective which will reduce cooling costs (but presumably increase heating costs in winter). In theory, this will cool the world, stop storms and save turtles.

Once, when we were rich we could afford to have colors on our buildings and to heat or cool them too.

Presumably this will also be good for the sunglass industry. Let’s hope it doesn’t cause more car accidents.

Climate change: ‘Cooling paint’ could cut emissions from buildings

Matt McGrath, BBC

A  new type of white paint has the potential to cool buildings and reduce the reliance on air conditioning, say researchers.

In a study, the new product was able to reflect 95.5% of sunlight and reduce temperatures by 1.7C compared to the ambient air conditions.

The engineers involved say the impact is achieved by adding different-sized particles of calcium carbonate.

Here’s wondering when the next study shows that a bunch of skyscrapers reflected white light away from themselves and towards other skyscapers, raising their cooling costs.
