global warming

Global warming is when the temperature rises on the earth. It is the result of human activities such as deforestation and burning of fossil fuels.

It happens when a large amount of carbon dioxide by millions of factories is released into the air. Part of this carbon dioxide in the air causes the air temperature to rise.

Global warming causes problems such as prolonged droughts, torrential rains and sometimes a rise in sea level has been noted as glaciers are melting at a fast rate.
