Can global warming be tackled with white paint?
In a new study, a scientist has come up with the suggestion that global warming may be tackled with white paint. According to a report in The Guardian, the scientist in question is Hashem Akbari from the Lawrence Berkeley National Laboratory in California, US, who suggests painting roads and the rooftops of buildings with the color white to fight global warming. Theory is based on the concept that white colour reflects enough of sunlight and heat back to the atmosphere which will help to delay global warming. He wants dozens of the world’s largest cities to unite in an effort to replace the dark-coloured materials used to cover roads and roofs with something a little more reflective. Study has shown that buildings with white roofs stay cooler during the summer. The change reduces the way heat accumulates in built-up areas (known as the urban heat island effect) and allows people who live and work inside to switch off power-hungry air conditioning units. Dark roofs reflect about 10-20 p
