Obama Energy Secretary: Paint World White to Fight Global Warming

As a weapon against global warming, it sounds so simple and low-tech that it could not possibly work.

But the idea of using millions of buckets of whitewash to avert climate catastrophe has won the backing of one of the world’s most influential scientists.

Steven Chu, the Nobel prize-winning physicist appointed by President Obama as Energy Secretary, wants to paint the world white.

A global initiative to change the color of roofs, roads and pavements so that they reflect more sunlight and heat could play a big part in containing global warming, he said Tuesday.

Speaking at the opening of the St. James’s Palace Nobel Laureate Symposium, for which The Times is media partner, Professor Chu said that this approach could have a vast impact.

By lightening paved surfaces and roofs to the color of cement, it would be possible to cut carbon emissions by as much as taking all the world’s cars off the roads for 11 years, he said.
