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.
According to scientists, if rooftops and roads were painted white it would reduce the amount of CO2 by
billions of tons. This would be the same as taking every car in the world off the streets for 11 years. Not only
wouldn’t this, but homes with white rooftops and cars that are painted white absorb so much heat from the
sun. This means that they would be cooler and people wouldn’t have to turn on their air conditioners as much.
Consequently, we would save more energy and reduce the amount of CO2 released in the atmosphere.
Although the idea of white rooftops has been generally welcomed by the scientific and environmental
communities, there appear to be a few problems. One of these is the fact that the colour white would be too
bright if it was painted on too many large surfaces. Another concern is that keeping the white surfaces in good
condition for a long period of time would be too expensive.
Pessimists feel that though painting rooftops and pavements in light colour 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.

1) There has been an increase in the amount of greenhouse gases in recent years.
2) Professor Chu suggests painting every large surface on the Earth white.
3) Buildings with white rooftops don’t need air conditioning.
4) Professor Chu's suggestion has been accepted by many experts.
5) Some people feel that painting surfaces white will not be enough to solve the problem of global warming.
