This document discusses global warming, including its causes, effects, and potential solutions. It begins by defining global warming as a slow increase in Earth's atmosphere temperature attributed to increased greenhouse gases. One prominent cause mentioned is the greenhouse effect, where gases like carbon dioxide trap heat. Effects discussed include more intense droughts and tropical storms, and rising sea levels. The document suggests reducing wasteful energy usage and developing alternative energy as ways to mitigate global warming impacts.

8. What is Global
Warming ?
A slow but sure escalation in
the overall temperature of the
Earth's atmosphere generally
attributed to the g r e e n h o u s e
effect caused by increased
levels of c ar bo n d io x i d e ,
CF C s, and other pollutants is
called G l o b a l W a r m i n g .

11. When greenhouse gases
like carbon dioxide, methane,
chlorofluorocarbon(CFC’s) etc.
trap the outgoing solar
radiations of the sun
reflected by the surface of
the earth and do not allow the
heat to escape then this is
known as greenhouse effect
which causes GLOBAL

12. Effects
Global Warming has numerous
harsh effects which are

19. What can be done ?
"As a society, we can blunt
the worsening of global warming by
immediately cutting back on our
wasteful energy usage. If we do
nothing, the effects will be much
worse."
