WHAT IS GLOBAL WARMING?
Global warming is the rise in average
temperature of the Earth’s atmosphere and
oceans. The Earth’s mean temperature has
increased by about 0.8 degree Celsius since
the late 19th century with about two-third of
the increase occurring after 1980.
According to scientists it is primarily caused
by increasing concentrations of greenhouse
gases produced by human activities such as
the burning of fossil fuels and deforestation.
