WHITE ROOFS FOR A BRIGHT FUTURE!
The effects of global warming are becoming more and more noticeable with the passing of the
years. The number of floods, storms and heatwaves has increased as a result of carbon
dioxide (CO2) and other greenhouse gases that do not allow the sun’s heat to escape the
Earth’s atmosphere. However, a simple and quite possibly effective idea has been suggested
as a way to help lessen the consequences of climate change.
Professor Steven Chu, the US Energy Secretary and a Nobel Prize winner, suggests that
painting our rooftops white will help the Earth’s temperature to drop. The idea is that if enough
surfaces - rooftops, pavements, roads - are painted white, more sunlight will reflect off these
surfaces and go back into space. This will help cool our planet down.
Pessimists feel that though painting rooftops and pavements in light colours is good in theory,
it is just a very small step to take towards reducing the Earth’s temperature. What we must
remember though, is that there is not one solution to global warming. It’s the combination of
different methods that will help our planet get back on its feet.
