This reminds me of ancient tribes and sun worship
Obama's green guru calls for white roofs
President Obama's energy adviser has suggested all the world's roofs should be painted white as part of efforts to slow global warming
Professor Steven Chu, the US Energy Secretary, said the unusual proposal would mean homes in hot countries would save energy and money on air conditioning by deflecting the sun's rays.
More pale surfaces could also slow global warming by reflecting heat into space rather than allowing it to be absorbed by dark surfaces where it is trapped by greenhouse gases and increases temperatures.
