The Problem of Global Warming
The problem of global warming, an increase in the average temperature on
Earth, is getting worse. The Earth has warmed 0.3 to 0.6 degrees Celsius since
the late 1800s. Scientists believe that the cause is the greenhouse effect, the
process of trapping heat in the Earth's atmosphere because of the presence of
large amounts of carbon dioxide, chlorofluorocarbons, methane, and nitrogen
oxides. Less oxygen is being produced and cleaning the atmosphere allowing more
of these gases to do its work on the environment.
