The Greenhouse Effect

The Greenhouse Effect is the name given to a suspected rise in temperatures around the world. This rise would be caused by the increasing amount of carbon dioxide and other "greenhouse gases"- such as methane and nitrous oxide- in the atmosphere. These gases come mainly from some power stations which burn coal or oil, vehicle exhausts and the burning of large areas of the world's rain forests. The Greenhouse Effect could lead to a rise in sea levels as polar ice caps melt, as well as very unpredictable weather.

>> There has been a 25 percent increase in amount of carbon dioxide in the atmosphere. This may be having a dangerous effect on the world's weather.
